+# Echo v5 Public API Changes
+
+**Comparison between `master` (v4.15.0) and `v5` (v5.0.0-alpha) branches**
+
+Generated: 2026-01-01
+
+---
+
+## Executive Summary (by authors)
+
+Echo `v5` is maintenance release with **major breaking changes**
+- `Context` is now struct instead of interface and we can add method to it in the future in minor versions.
+- Adds new `Router` interface for possible new routing implementations.
+- Drops old logging interface and uses moderm `log/slog` instead.
+- Rearranges alot of methods/function signatures to make them more consistent.
+
+## Executive Summary (by LLMs)
+
+Echo v5 represents a **major breaking release** with significant architectural changes focused on:
+- **Updated generic helpers** to take `*Context` and rename form helpers to `FormValue*`
+- **Simplified API surface** by moving Context from interface to concrete struct
+- **Modern Go patterns** including slog.Logger integration
+- **Enhanced routing** with explicit RouteInfo and Routes types
+- **Better error handling** with simplified HTTPError
+- **New test helpers** via the `echotest` package
+
+### Change Statistics
+
+- **Major Breaking Changes**: 15+
+- **New Functions Added**: 30+
+- **Type Signature Changes**: 20+
+- **Removed APIs**: 10+
+- **New Packages Added**: 1 (`echotest`)
+- **Version Change**: `4.15.0` → `5.0.0-alpha`
+
+---
+
+## Critical Breaking Changes
+
+### 1. **Context: Interface → Concrete Struct**
+
+**v4 (master):**
+```go
+type Context interface {
+ Request() *http.Request
+ // ... many methods
+}
+
+// Handler signature
+func handler(c echo.Context) error
+```
+
+**v5:**
+```go
+type Context struct {
+ // Has unexported fields
+}
+
+// Handler signature - NOW USES POINTER!
+func handler(c *echo.Context) error
+```
+
+**Impact:** 🔴 **CRITICAL BREAKING CHANGE**
+- ALL handlers must change from `echo.Context` to `*echo.Context`
+- Context is now a concrete struct, not an interface
+- This affects every single handler function in user code
+
+**Migration:**
+```go
+// Before (v4)
+func MyHandler(c echo.Context) error {
+ return c.JSON(200, map[string]string{"hello": "world"})
+}
+
+// After (v5)
+func MyHandler(c *echo.Context) error {
+ return c.JSON(200, map[string]string{"hello": "world"})
+}
+```
+
+---
+
+### 2. **Logger: Custom Interface → slog.Logger**
+
+**v4:**
+```go
+type Echo struct {
+ Logger Logger // Custom interface with Print, Debug, Info, etc.
+}
+
+type Logger interface {
+ Output() io.Writer
+ SetOutput(w io.Writer)
+ Prefix() string
+ // ... many custom methods
+}
+
+// Context returns Logger interface
+func (c Context) Logger() Logger
+```
+
+**v5:**
+```go
+type Echo struct {
+ Logger *slog.Logger // Standard library structured logger
+}
+
+// Context returns slog.Logger
+func (c *Context) Logger() *slog.Logger
+func (c *Context) SetLogger(logger *slog.Logger)
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Must use Go's standard `log/slog` package
+- Logger interface completely removed
+- All logging code needs updating
+
+---
+
+### 3. **Router: From Router to DefaultRouter**
+
+**v4:**
+```go
+type Router struct { ... }
+
+func NewRouter(e *Echo) *Router
+func (e *Echo) Router() *Router
+```
+
+**v5:**
+```go
+type DefaultRouter struct { ... }
+
+func NewRouter(config RouterConfig) *DefaultRouter
+func (e *Echo) Router() Router // Returns interface
+```
+
+**Changes:**
+- New `Router` interface introduced
+- `DefaultRouter` is the concrete implementation
+- `NewRouter()` now takes `RouterConfig` instead of `*Echo`
+- Added `NewConcurrentRouter(r Router) Router` for thread-safe routing
+
+---
+
+### 4. **Route Return Types Changed**
+
+**v4:**
+```go
+func (e *Echo) GET(path string, h HandlerFunc, m ...MiddlewareFunc) *Route
+func (e *Echo) Any(path string, h HandlerFunc, m ...MiddlewareFunc) []*Route
+func (e *Echo) Routes() []*Route
+```
+
+**v5:**
+```go
+func (e *Echo) GET(path string, h HandlerFunc, m ...MiddlewareFunc) RouteInfo
+func (e *Echo) Any(path string, h HandlerFunc, m ...MiddlewareFunc) RouteInfo
+func (e *Echo) Match(...) Routes // Returns Routes type
+func (e *Echo) Router() Router // Returns interface
+```
+
+**New Types:**
+```go
+type RouteInfo struct {
+ Name string
+ Method string
+ Path string
+ Parameters []string
+}
+
+type Routes []RouteInfo // Collection with helper methods
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Route registration methods return `RouteInfo` instead of `*Route`
+- New `Routes` collection type with filtering methods
+- `Route` struct still exists but used differently
+
+---
+
+### 5. **Response Type Changed**
+
+**v4:**
+```go
+func (c Context) Response() *Response
+type Response struct {
+ Writer http.ResponseWriter
+ Status int
+ Size int64
+ Committed bool
+}
+func NewResponse(w http.ResponseWriter, e *Echo) *Response
+```
+
+**v5:**
+```go
+func (c *Context) Response() http.ResponseWriter
+type Response struct {
+ http.ResponseWriter // Embedded
+ Status int
+ Size int64
+ Committed bool
+}
+func NewResponse(w http.ResponseWriter, logger *slog.Logger) *Response
+func UnwrapResponse(rw http.ResponseWriter) (*Response, error)
+```
+
+**Changes:**
+- Context.Response() returns `http.ResponseWriter` instead of `*Response`
+- Response now embeds `http.ResponseWriter`
+- NewResponse takes `*slog.Logger` instead of `*Echo`
+- New `UnwrapResponse()` helper function
+
+---
+
+### 6. **HTTPError Simplified**
+
+**v4:**
+```go
+type HTTPError struct {
+ Internal error
+ Message interface{} // Can be any type
+ Code int
+}
+
+func NewHTTPError(code int, message ...interface{}) *HTTPError
+```
+
+**v5:**
+```go
+type HTTPError struct {
+ Code int
+ Message string // Now string only
+ // Has unexported fields (Internal moved)
+}
+
+func NewHTTPError(code int, message string) *HTTPError
+func (he HTTPError) Wrap(err error) error // New method
+func (he *HTTPError) StatusCode() int // Implements HTTPStatusCoder
+```
+
+**Changes:**
+- `Message` field changed from `interface{}` to `string`
+- `NewHTTPError()` now takes `string` instead of `...interface{}`
+- Added `HTTPStatusCoder` interface and `StatusCode()` method
+- Added `Wrap(err error)` method for error wrapping
+
+---
+
+### 7. **HTTPErrorHandler Signature Changed**
+
+**v4:**
+```go
+type HTTPErrorHandler func(err error, c Context)
+
+func (e *Echo) DefaultHTTPErrorHandler(err error, c Context)
+```
+
+**v5:**
+```go
+type HTTPErrorHandler func(c *Context, err error) // Parameters swapped!
+
+func DefaultHTTPErrorHandler(exposeError bool) HTTPErrorHandler // Now a factory
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Parameter order reversed: `(c *Context, err error)` instead of `(err error, c Context)`
+- DefaultHTTPErrorHandler is now a factory function that returns HTTPErrorHandler
+- Takes `exposeError` bool to control error message exposure
+
+---
+
+## Notable API Changes in v5
+
+### 1. **Generic Parameter Extraction Functions (Updated Signatures)**
+
+These helpers keep the same generic API but now accept `*Context`, and the
+form helpers are renamed from `FormParam*` to `FormValue*`:
+
+```go
+// Query Parameters
+func QueryParam[T any](c *Context, key string, opts ...any) (T, error)
+func QueryParamOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func QueryParams[T any](c *Context, key string, opts ...any) ([]T, error)
+func QueryParamsOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// Path Parameters
+func PathParam[T any](c *Context, paramName string, opts ...any) (T, error)
+func PathParamOr[T any](c *Context, paramName string, defaultValue T, opts ...any) (T, error)
+
+// Form Values
+func FormValue[T any](c *Context, key string, opts ...any) (T, error)
+func FormValueOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func FormValues[T any](c *Context, key string, opts ...any) ([]T, error)
+func FormValuesOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// Generic Parsing
+func ParseValue[T any](value string, opts ...any) (T, error)
+func ParseValueOr[T any](value string, defaultValue T, opts ...any) (T, error)
+func ParseValues[T any](values []string, opts ...any) ([]T, error)
+func ParseValuesOr[T any](values []string, defaultValue []T, opts ...any) ([]T, error)
+```
+
+`FormParam*` was renamed to `FormValue*`; the rest keep names but now take `*Context`.
+
+**Supported Types:**
+- bool, string
+- int, int8, int16, int32, int64
+- uint, uint8, uint16, uint32, uint64
+- float32, float64
+- time.Time, time.Duration
+- BindUnmarshaler, encoding.TextUnmarshaler, json.Unmarshaler
+
+**Example Usage:**
+```go
+// v5 - Type-safe parameter binding
+id, err := echo.PathParam[int](c, "id")
+page, err := echo.QueryParamOr[int](c, "page", 1)
+tags, err := echo.QueryParams[string](c, "tags")
+```
+
+---
+
+### 2. **Context Store Helpers Now Use `*Context`**
+
+```go
+// Type-safe context value retrieval
+func ContextGet[T any](c *Context, key string) (T, error)
+func ContextGetOr[T any](c *Context, key string, defaultValue T) (T, error)
+
+// Error types
+var ErrNonExistentKey = errors.New("non existent key")
+var ErrInvalidKeyType = errors.New("invalid key type")
+```
+
+These helpers existed in v4 with `Context` and now accept `*Context`.
+
+**Example:**
+```go
+// v5
+user, err := echo.ContextGet[*User](c, "user")
+count, err := echo.ContextGetOr[int](c, "count", 0)
+```
+
+---
+
+### 3. **PathValues Type**
+
+New structured path parameter handling:
+
+```go
+type PathValue struct {
+ Name string
+ Value string
+}
+
+type PathValues []PathValue
+
+func (p PathValues) Get(name string) (string, bool)
+func (p PathValues) GetOr(name string, defaultValue string) string
+
+// Context methods
+func (c *Context) PathValues() PathValues
+func (c *Context) SetPathValues(pathValues PathValues)
+```
+
+---
+
+### 4. **Time Parsing Options**
+
+```go
+type TimeLayout string
+
+const (
+ TimeLayoutUnixTime = TimeLayout("UnixTime")
+ TimeLayoutUnixTimeMilli = TimeLayout("UnixTimeMilli")
+ TimeLayoutUnixTimeNano = TimeLayout("UnixTimeNano")
+)
+
+type TimeOpts struct {
+ Layout TimeLayout
+ ParseInLocation *time.Location
+ ToInLocation *time.Location
+}
+```
+
+---
+
+### 5. **StartConfig for Server Configuration**
+
+```go
+type StartConfig struct {
+ Address string
+ HideBanner bool
+ HidePort bool
+ CertFilesystem fs.FS
+ TLSConfig *tls.Config
+ ListenerNetwork string
+ ListenerAddrFunc func(addr net.Addr)
+ GracefulTimeout time.Duration
+ OnShutdownError func(err error)
+ BeforeServeFunc func(s *http.Server) error
+}
+
+func (sc StartConfig) Start(ctx context.Context, h http.Handler) error
+func (sc StartConfig) StartTLS(ctx context.Context, h http.Handler, certFile, keyFile any) error
+```
+
+**Example:**
+```go
+// v5 - More control over server startup
+ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
+defer cancel()
+
+sc := echo.StartConfig{
+ Address: ":8080",
+ GracefulTimeout: 10 * time.Second,
+}
+if err := sc.Start(ctx, e); err != nil {
+ log.Fatal(err)
+}
+```
+
+---
+
+### 6. **Echo Config and Constructors**
+
+```go
+type Config struct {
+ // Configuration for Echo (logger, binder, renderer, etc.)
+}
+
+func NewWithConfig(config Config) *Echo
+```
+
+This adds a configuration struct for creating an `Echo` instance without
+mutating fields after `New()`.
+
+---
+
+### 7. **Enhanced Routing Features**
+
+```go
+// New route methods
+func (e *Echo) AddRoute(route Route) (RouteInfo, error)
+func (e *Echo) Middlewares() []MiddlewareFunc
+func (e *Echo) PreMiddlewares() []MiddlewareFunc
+type AddRouteError struct{ ... }
+
+// Routes collection with filters
+type Routes []RouteInfo
+
+func (r Routes) Clone() Routes
+func (r Routes) FilterByMethod(method string) (Routes, error)
+func (r Routes) FilterByName(name string) (Routes, error)
+func (r Routes) FilterByPath(path string) (Routes, error)
+func (r Routes) FindByMethodPath(method string, path string) (RouteInfo, error)
+func (r Routes) Reverse(routeName string, pathValues ...any) (string, error)
+
+// RouteInfo operations
+func (r RouteInfo) Clone() RouteInfo
+func (r RouteInfo) Reverse(pathValues ...any) string
+```
+
+---
+
+### 8. **Middleware Configuration Interface**
+
+```go
+type MiddlewareConfigurator interface {
+ ToMiddleware() (MiddlewareFunc, error)
+}
+```
+
+Allows middleware configs to be converted to middleware without panicking.
+
+---
+
+### 9. **New Context Methods**
+
+```go
+// v5 additions
+func (c *Context) FileFS(file string, filesystem fs.FS) error
+func (c *Context) FormValueOr(name, defaultValue string) string
+func (c *Context) InitializeRoute(ri *RouteInfo, pathValues *PathValues)
+func (c *Context) ParamOr(name, defaultValue string) string
+func (c *Context) QueryParamOr(name, defaultValue string) string
+func (c *Context) RouteInfo() RouteInfo
+```
+
+---
+
+### 10. **Virtual Host Support**
+
+```go
+func NewVirtualHostHandler(vhosts map[string]*Echo) *Echo
+```
+
+Creates an Echo instance that routes requests to different Echo instances based on host.
+
+---
+
+### 11. **New Binder Functions**
+
+```go
+func BindBody(c *Context, target any) error
+func BindHeaders(c *Context, target any) error
+func BindPathValues(c *Context, target any) error // Renamed from BindPathParams
+func BindQueryParams(c *Context, target any) error
+```
+
+Top-level binding functions that work with `*Context`.
+
+---
+
+### 12. **New echotest Package**
+
+```go
+package echotest // import "github.com/labstack/echo/v5/echotest"
+
+func LoadBytes(t *testing.T, name string, opts ...loadBytesOpts) []byte
+func TrimNewlineEnd(bytes []byte) []byte
+type ContextConfig struct{ ... }
+type MultipartForm struct{ ... }
+type MultipartFormFile struct{ ... }
+```
+
+Helpers for loading fixtures and constructing test contexts.
+
+---
+
+## Removed APIs in v5
+
+### Constants
+
+```go
+// v4 - Removed in v5
+const CONNECT = http.MethodConnect // Use http.MethodConnect directly
+```
+
+**Reason:** Deprecated in v4, use stdlib `http.Method*` constants instead.
+
+---
+
+### Constants Added in v5
+
+```go
+// v5 additions
+const (
+ NotFoundRouteName = "echo_route_not_found_name"
+)
+```
+
+---
+
+### Error Variable Changes
+
+**v4 exports:**
+```go
+ErrBadRequest
+ErrInvalidKeyType
+ErrNonExistentKey
+```
+
+**v5 exports:**
+```go
+ErrBadRequest // Now backed by unexported httpError type
+ErrValidatorNotRegistered // New
+ErrInvalidKeyType
+ErrNonExistentKey
+```
+
+**Reason:** v5 centralizes on `NewHTTPError(code, message)` rather than a broad set
+of predefined HTTP error variables.
+
+---
+
+### Functions Removed
+
+```go
+// v4 - Removed in v5
+func GetPath(r *http.Request) string // Use r.URL.Path or r.URL.RawPath
+```
+
+### Variables Removed
+
+```go
+// v4 - Removed in v5
+var MethodNotAllowedHandler = func(c Context) error { ... }
+var NotFoundHandler = func(c Context) error { ... }
+```
+
+### Functions Renamed
+
+```go
+// v4
+func FormParam[T any](c Context, key string, opts ...any) (T, error)
+func FormParamOr[T any](c Context, key string, defaultValue T, opts ...any) (T, error)
+func FormParams[T any](c Context, key string, opts ...any) ([]T, error)
+func FormParamsOr[T any](c Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// v5
+func FormValue[T any](c *Context, key string, opts ...any) (T, error)
+func FormValueOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func FormValues[T any](c *Context, key string, opts ...any) ([]T, error)
+func FormValuesOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+```
+
+---
+
+### Type Methods Removed/Changed
+
+**Echo struct changes:**
+```go
+// v4 fields removed in v5
+type Echo struct {
+ StdLogger *stdLog.Logger // Removed
+ Server *http.Server // Removed (use StartConfig)
+ TLSServer *http.Server // Removed (use StartConfig)
+ Listener net.Listener // Removed (use StartConfig)
+ TLSListener net.Listener // Removed (use StartConfig)
+ AutoTLSManager autocert.Manager // Removed
+ ListenerNetwork string // Removed
+ OnAddRouteHandler func(...) // Changed to OnAddRoute
+ DisableHTTP2 bool // Removed (use StartConfig)
+ Debug bool // Removed
+ HideBanner bool // Removed (use StartConfig)
+ HidePort bool // Removed (use StartConfig)
+}
+
+// v5 Echo struct (simplified)
+type Echo struct {
+ Binder Binder
+ Filesystem fs.FS // NEW
+ Renderer Renderer
+ Validator Validator
+ JSONSerializer JSONSerializer
+ IPExtractor IPExtractor
+ OnAddRoute func(route Route) error // Simplified
+ HTTPErrorHandler HTTPErrorHandler
+ Logger *slog.Logger // Changed from Logger interface
+}
+```
+
+---
+
+**Context interface → struct:**
+```go
+// v4
+type Context interface {
+ // Had: SetResponse(*Response)
+ Response() *Response
+
+ // Had: ParamNames(), SetParamNames(), ParamValues(), SetParamValues()
+ // These are removed in v5 (use PathValues() instead)
+}
+
+// v5
+type Context struct {
+ // Concrete struct with unexported fields
+}
+
+func (c *Context) Response() http.ResponseWriter // Changed return type
+func (c *Context) PathValues() PathValues // Replaces ParamNames/Values
+```
+
+---
+
+**Types removed:**
+```go
+// v4
+type Map map[string]interface{}
+```
+
+**Group changes:**
+```go
+// v4
+func (g *Group) File(path, file string) // No return value
+func (g *Group) Static(pathPrefix, fsRoot string) // No return value
+func (g *Group) StaticFS(pathPrefix string, filesystem fs.FS) // No return value
+
+// v5
+func (g *Group) File(path, file string, middleware ...MiddlewareFunc) RouteInfo
+func (g *Group) Static(pathPrefix, fsRoot string, middleware ...MiddlewareFunc) RouteInfo
+func (g *Group) StaticFS(pathPrefix string, filesystem fs.FS, middleware ...MiddlewareFunc) RouteInfo
+```
+
+Now return `RouteInfo` and accept middleware.
+
+---
+
+### Value Binder Factory Name Changes
+
+```go
+// v4
+func PathParamsBinder(c Context) *ValueBinder
+func QueryParamsBinder(c Context) *ValueBinder
+func FormFieldBinder(c Context) *ValueBinder
+
+// v5
+func PathValuesBinder(c *Context) *ValueBinder // Renamed
+func QueryParamsBinder(c *Context) *ValueBinder
+func FormFieldBinder(c *Context) *ValueBinder
+```
+
+---
+
+## Type Signature Changes
+
+### Binder Interface
+
+```go
+// v4
+type Binder interface {
+ Bind(i interface{}, c Context) error
+}
+
+// v5
+type Binder interface {
+ Bind(c *Context, target any) error // Parameters swapped!
+}
+```
+
+---
+
+### DefaultBinder Methods
+
+```go
+// v4
+func (b *DefaultBinder) Bind(i interface{}, c Context) error
+func (b *DefaultBinder) BindBody(c Context, i interface{}) error
+func (b *DefaultBinder) BindPathParams(c Context, i interface{}) error
+
+// v5
+func (b *DefaultBinder) Bind(c *Context, target any) error // Swapped params
+// BindBody, BindPathParams, etc. are now top-level functions
+```
+
+---
+
+### JSONSerializer Interface
+

+## Router Interface Changes
+
+### v4 Router (Concrete Struct)
+
+```go
+type Router struct { ... }
+
+func NewRouter(e *Echo) *Router
+func (r *Router) Add(method, path string, h HandlerFunc)
+func (r *Router) Find(method, path string, c Context)
+func (r *Router) Reverse(name string, params ...interface{}) string
+func (r *Router) Routes() []*Route
+```
+
+### v5 Router (Interface + DefaultRouter)
+
+```go
+type Router interface {
+ Add(routable Route) (RouteInfo, error)
+ Remove(method string, path string) error
+ Routes() Routes
+ Route(c *Context) HandlerFunc

+- DefaultRouter is the concrete implementation
+- Add() returns `(RouteInfo, error)` instead of being void
+- New `Remove()` method
+- New `Route()` method replaces `Find()`
+- Configuration through `RouterConfig`
+
+---
+
+## Echo Instance Method Changes
+
+### Route Registration
+
+```go
+// v4
+func (e *Echo) Add(method, path string, handler HandlerFunc, middleware ...MiddlewareFunc) *Route
+
+// v5
+func (e *Echo) Add(method, path string, handler HandlerFunc, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) AddRoute(route Route) (RouteInfo, error) // NEW
+```
+
+### Static File Serving
+
+```go
+// v4
+func (e *Echo) Static(pathPrefix, fsRoot string) *Route
+func (e *Echo) StaticFS(pathPrefix string, filesystem fs.FS) *Route
+func (e *Echo) File(path, file string, m ...MiddlewareFunc) *Route
+func (e *Echo) FileFS(path, file string, filesystem fs.FS, m ...MiddlewareFunc) *Route
+
+// v5
+func (e *Echo) Static(pathPrefix, fsRoot string, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) StaticFS(pathPrefix string, filesystem fs.FS, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) File(path, file string, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) FileFS(path, file string, filesystem fs.FS, m ...MiddlewareFunc) RouteInfo
+```
+
+Return type changed from `*Route` to `RouteInfo`.
+
+### Server Management
+
+```go
+// v4
+func (e *Echo) Start(address string) error
+func (e *Echo) StartTLS(address string, certFile, keyFile interface{}) error
+func (e *Echo) StartAutoTLS(address string) error

+
+// v5
+func (e *Echo) Start(address string) error // Simplified
+func (e *Echo) ServeHTTP(w http.ResponseWriter, r *http.Request)
+
+// Removed: StartTLS, StartAutoTLS, StartH2CServer, StartServer
+// Use StartConfig instead for advanced server configuration
+// Removed: Shutdown, Close, ListenerAddr, TLSListenerAddr
+// Removed: DefaultHTTPErrorHandler (now a top-level factory function)
+```
+
+**v5 provides** `StartConfig` type for all advanced server configuration.
+
+### Router Access
+
+```go
+// v4
+func (e *Echo) Router() *Router

+func (e *Echo) Router() Router // Returns interface
+// Removed: Routers(), Reverse(), URI(), URL(), Host()
+// Use router.Routes() and Routes.Reverse() instead
+```
+
+---
+
+## NewContext Changes
+
+```go
+// v4
+func (e *Echo) NewContext(r *http.Request, w http.ResponseWriter) Context

+
+## Migration Guide Summary
+
+If you are using Linux you can migrate easier parts like that:
+```bash
+find . -type f -name "*.go" -exec sed -i 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i 's/echo\/v4/echo\/v5/g' {} +
+```
+or in your favorite IDE
+
+Replace all:
+1. ` echo.Context` -> ` *echo.Context`
+2. `echo/v4` -> `echo/v5`
+
+
+### 1. Update All Handler Signatures
+
+```go
+// Before
+func MyHandler(c echo.Context) error { ... }
+
+// After
+func MyHandler(c *echo.Context) error { ... }
+```
+
+### 2. Update Logger Usage
+
+```go
+// Before
+e.Logger.Info("Server started")
+c.Logger().Error("Something went wrong")
+
+// After
+e.Logger.Info("Server started")
+c.Logger().Error("Something went wrong") // Same API, different logger
+```
+
+### 3. Use Type-Safe Parameter Extraction
+
+```go
+// Before
+idStr := c.Param("id")
+id, err := strconv.Atoi(idStr)
+
+// After
+id, err := echo.PathParam[int](c, "id")
+```
+
+### 4. Update Error Handler
+
+```go
+// Before
+e.HTTPErrorHandler = func(err error, c echo.Context) {
+ // handle error
+}
+
+// After
+e.HTTPErrorHandler = func(c *echo.Context, err error) { // Swapped!
+ // handle error
+}
+
+// Or use factory
+e.HTTPErrorHandler = echo.DefaultHTTPErrorHandler(true) // exposeError=true
+```
+
+### 5. Update Server Startup
+
+```go
+// Before
+e.Start(":8080")
+e.StartTLS(":443", "cert.pem", "key.pem")
+
+// After
+// Simple
+e.Start(":8080")
+
+// Advanced with graceful shutdown
+ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt)
+defer cancel()
+sc := echo.StartConfig{Address: ":8080"}
+sc.Start(ctx, e)
+```
+
+### 6. Update Route Info Access
+
+```go
+// Before
+routes := e.Routes()
+for _, r := range routes {
+ fmt.Println(r.Method, r.Path)
+}
+
+// After
+routes := e.Router().Routes()
+for _, r := range routes {
+ fmt.Println(r.Method, r.Path)
+}
+```
+
+### 7. Update HTTPError Creation
+
+```go
+// Before
+return echo.NewHTTPError(400, "invalid request", someDetail)
+
+// After
+return echo.NewHTTPError(400, "invalid request")
+```
+
+### 8. Update Custom Binder
+
+```go
+// Before
+type MyBinder struct{}
+func (b *MyBinder) Bind(i interface{}, c echo.Context) error { ... }
+
+// After
+type MyBinder struct{}
+func (b *MyBinder) Bind(c *echo.Context, target any) error { ... } // Swapped!
+```
+
+### 9. Path Parameters
+
+```go
+// Before
+names := c.ParamNames()
+values := c.ParamValues()
+
+// After
+pathValues := c.PathValues()
+for _, pv := range pathValues {
+ fmt.Println(pv.Name, pv.Value)
+}
+```
+
+### 10. Response Access
+
+```go
+// Before
+resp := c.Response()
+resp.Header().Set("X-Custom", "value")
+

# Changelog
+## v5.0.3 - 2026-02-06
+
+**Security**
+
+* Fix directory traversal vulnerability under Windows in Static middleware when default Echo filesystem is used. Reported by @shblue21.
+
+This applies to cases when:
+- Windows is used as OS
+- `middleware.StaticConfig.Filesystem` is `nil` (default)
+- `echo.Filesystem` is has not been set explicitly (default)
+
+Exposure is restricted to the active process working directory and its subfolders.
+
+
+## v5.0.2 - 2026-02-02
+
+**Security**
+
+* Fix Static middleware with `config.Browse=true` lists all files/subfolders from `config.Filesystem` root and not starting from `config.Root` in https://github.com/labstack/echo/pull/2887
+
+
+## v5.0.1 - 2026-01-28
+
+* Panic MW: will now return a custom PanicStackError with stack trace by @aldas in https://github.com/labstack/echo/pull/2871
+* Docs: add missing err parameter to DenyHandler example by @cgalibern in https://github.com/labstack/echo/pull/2878
+* improve: improve websocket checks in IsWebSocket() [per RFC 6455] by @raju-mechatronics in https://github.com/labstack/echo/pull/2875
+* fix: Context.Json() should not send status code before serialization is complete by @aldas in https://github.com/labstack/echo/pull/2877
+
+
+## v5.0.0 - 2026-01-18
+
+Echo `v5` is maintenance release with **major breaking changes**
+- `Context` is now struct instead of interface and we can add method to it in the future in minor versions.
+- Adds new `Router` interface for possible new routing implementations.
+- Drops old logging interface and uses moderm `log/slog` instead.
+- Rearranges alot of methods/function signatures to make them more consistent.
+
+Upgrade notes and `v4` support:
+- Echo `v4` is supported with **security*** updates and **bug** fixes until **2026-12-31**
+- If you are using Echo in a production environment, it is recommended to wait until after 2026-03-31 before upgrading.
+- Until 2026-03-31, any critical issues requiring breaking `v5` API changes will be addressed, even if this violates semantic versioning.
+
+See [API_CHANGES_V5.md](./API_CHANGES_V5.md) for public API changes between `v4` and `v5`, notes on **upgrading**.
+
+Upgrading TLDR:
+
+If you are using Linux you can migrate easier parts like that:
+```bash
+find . -type f -name "*.go" -exec sed -i 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i 's/echo\/v4/echo\/v5/g' {} +
+```
+macOS
+```bash
+find . -type f -name "*.go" -exec sed -i '' 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i '' 's/echo\/v4/echo\/v5/g' {} +
+```
+
+or in your favorite IDE
+
+Replace all:
+1. ` echo.Context` -> ` *echo.Context`
+2. `echo/v4` -> `echo/v5`
+
+This should solve most of the issues. Probably the hardest part is updating all the tests.
+
+
+## v4.15.0 - 2026-01-01
+
+
+**Security**
+
+NB: **If your application relies on cross-origin or same-site (same subdomain) requests do not blindly push this version to production**
+
+
+The CSRF middleware now supports the [**Sec-Fetch-Site**](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Sec-Fetch-Site) header as a modern, defense-in-depth approach to [CSRF
+protection](https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html#fetch-metadata-headers), implementing the OWASP-recommended Fetch Metadata API alongside the traditional token-based mechanism.
+
+**How it works:**
+
+Modern browsers automatically send the `Sec-Fetch-Site` header with all requests, indicating the relationship
+between the request origin and the target. The middleware uses this to make security decisions:
+
+- **`same-origin`** or **`none`**: Requests are allowed (exact origin match or direct user navigation)
+- **`same-site`**: Falls back to token validation (e.g., subdomain to main domain)
+- **`cross-site`**: Blocked by default with 403 error for unsafe methods (POST, PUT, DELETE, PATCH)
+
+For browsers that don't send this header (older browsers), the middleware seamlessly falls back to
+traditional token-based CSRF protection.
+
+**New Configuration Options:**
+- `TrustedOrigins []string`: Allowlist specific origins for cross-site requests (useful for OAuth callbacks, webhooks)
+- `AllowSecFetchSiteFunc func(echo.Context) (bool, error)`: Custom logic for same-site/cross-site request validation
+
+**Example:**
+ ```go
+ e.Use(middleware.CSRFWithConfig(middleware.CSRFConfig{
+ // Allow OAuth callbacks from trusted provider
+ TrustedOrigins: []string{"https://oauth-provider.com"},
+
+ // Custom validation for same-site requests
+ AllowSecFetchSiteFunc: func(c echo.Context) (bool, error) {
+ // Your custom authorization logic here
+ return validateCustomAuth(c), nil
+ // return true, err // blocks request with error
+ // return true, nil // allows CSRF request through
+ // return false, nil // falls back to legacy token logic
+ },
+ }))
+ ```
+PR: https://github.com/labstack/echo/pull/2858
+
+**Type-Safe Generic Parameter Binding**
+
+* Added generic functions for type-safe parameter extraction and context access by @aldas in https://github.com/labstack/echo/pull/2856
+
+ Echo now provides generic functions for extracting path, query, and form parameters with automatic type conversion,
+ eliminating manual string parsing and type assertions.
+
+ **New Functions:**
+ - Path parameters: `PathParam[T]`, `PathParamOr[T]`
+ - Query parameters: `QueryParam[T]`, `QueryParamOr[T]`, `QueryParams[T]`, `QueryParamsOr[T]`
+ - Form values: `FormParam[T]`, `FormParamOr[T]`, `FormParams[T]`, `FormParamsOr[T]`
+ - Context store: `ContextGet[T]`, `ContextGetOr[T]`
+
+ **Supported Types:**
+ Primitives (`bool`, `string`, `int`/`uint` variants, `float32`/`float64`), `time.Duration`, `time.Time`
+ (with custom layouts and Unix timestamp support), and custom types implementing `BindUnmarshaler`,
+ `TextUnmarshaler`, or `JSONUnmarshaler`.
+
+ **Example:**
+ ```go
+ // Before: Manual parsing
+ idStr := c.Param("id")
+ id, err := strconv.Atoi(idStr)
+
+ // After: Type-safe with automatic parsing
+ id, err := echo.PathParam[int](c, "id")
+
+ // With default values
+ page, err := echo.QueryParamOr[int](c, "page", 1)
+ limit, err := echo.QueryParamOr[int](c, "limit", 20)
+
+ // Type-safe context access (no more panics from type assertions)
+ user, err := echo.ContextGet[*User](c, "user")
+ ```
+
+PR: https://github.com/labstack/echo/pull/2856
+
+
+
+**DEPRECATION NOTICE** Timeout Middleware Deprecated - Use ContextTimeout Instead
+
+The `middleware.Timeout` middleware has been **deprecated** due to fundamental architectural issues that cause
+data races. Use `middleware.ContextTimeout` or `middleware.ContextTimeoutWithConfig` instead.
+
+**Why is this being deprecated?**
+
+The Timeout middleware manipulates response writers across goroutine boundaries, which causes data races that
+cannot be reliably fixed without a complete architectural redesign. The middleware:
+
+- Swaps the response writer using `http.TimeoutHandler`
+- Must be the first middleware in the chain (fragile constraint)
+- Can cause races with other middleware (Logger, metrics, custom middleware)
+- Has been the source of multiple race condition fixes over the years
+
+**What should you use instead?**
+
+The `ContextTimeout` middleware (available since v4.12.0) provides timeout functionality using Go's standard
+context mechanism. It is:
+
+- Race-free by design
+- Can be placed anywhere in the middleware chain
+- Simpler and more maintainable
+- Compatible with all other middleware
+
+**Migration Guide:**
+
+```go
+// Before (deprecated):
+e.Use(middleware.Timeout())
+
+// After (recommended):
+e.Use(middleware.ContextTimeout(30 * time.Second))
+```
+
+**Important Behavioral Differences:**
+
+1. **Handler cooperation required**: With ContextTimeout, your handlers must check `context.Done()` for cooperative
+ cancellation. The old Timeout middleware would send a 503 response regardless of handler cooperation, but had
+ data race issues.
+
+2. **Error handling**: ContextTimeout returns errors through the standard error handling flow. Handlers that receive
+ `context.DeadlineExceeded` should handle it appropriately:
+
+```go
+e.GET("/long-task", func(c echo.Context) error {
+ ctx := c.Request().Context()
+
+ // Example: database query with context
+ result, err := db.QueryContext(ctx, "SELECT * FROM large_table")
+ if err != nil {
+ if errors.Is(err, context.DeadlineExceeded) {
+ // Handle timeout
+ return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
+ }
+ return err
+ }
+
+ return c.JSON(http.StatusOK, result)
+})
+```
+
+3. **Background tasks**: For long-running background tasks, use goroutines with context:
+
+```go
+e.GET("/async-task", func(c echo.Context) error {
+ ctx := c.Request().Context()
+
+ resultCh := make(chan Result, 1)
+ errCh := make(chan error, 1)
+
+ go func() {
+ result, err := performLongTask(ctx)
+ if err != nil {
+ errCh <- err
+ return
+ }
+ resultCh <- result
+ }()
+
+ select {
+ case result := <-resultCh:
+ return c.JSON(http.StatusOK, result)
+ case err := <-errCh:
+ return err
+ case <-ctx.Done():
+ return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
+ }
+})
+```

+
+
+## v4.14.0 - 2025-12-11
+
+`middleware.Logger` has been deprecated. For request logging, use `middleware.RequestLogger` or
+`middleware.RequestLoggerWithConfig`.
+
+`middleware.RequestLogger` replaces `middleware.Logger`, offering comparable configuration while relying on the
+Go standard library’s new `slog` logger.
+
+The previous default output format was JSON. The new default follows the standard `slog` logger settings.
+To continue emitting request logs in JSON, configure `slog` accordingly:
+```go
+slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
+e.Use(middleware.RequestLogger())
+```

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## About This Project
+
+Echo is a high performance, minimalist Go web framework. This is the main repository for Echo v4, which is available as a Go module at `github.com/labstack/echo/v4`.
+
+## Development Commands
+
+The project uses a Makefile for common development tasks:
+
+- `make check` - Run linting, vetting, and race condition tests (default target)
+- `make init` - Install required linting tools (golint, staticcheck)
+- `make lint` - Run staticcheck and golint
+- `make vet` - Run go vet
+- `make test` - Run short tests
+- `make race` - Run tests with race detector
+- `make benchmark` - Run benchmarks
+
+Example commands for development:
+```bash
+# Setup development environment
+make init
+
+# Run all checks (lint, vet, race)
+make check
+
+# Run specific tests
+go test ./middleware/...
+go test -race ./...
+
+# Run benchmarks
+make benchmark
+```
+
+## Code Architecture
+
+### Core Components
+
+**Echo Instance (`echo.go`)**
+- The `Echo` struct is the top-level framework instance
+- Contains router, middleware stacks, and server configuration
+- Not goroutine-safe for mutations after server start
+
+**Context (`context.go`)**
+- The `Context` interface represents HTTP request/response context
+- Provides methods for request/response handling, path parameters, data binding
+- Core abstraction for request processing
+
+**Router (`router.go`)**
+- Radix tree-based HTTP router with smart route prioritization
+- Supports static routes, parameterized routes (`/users/:id`), and wildcard routes (`/static/*`)
+- Each HTTP method has its own routing tree
+
+**Middleware (`middleware/`)**
+- Extensive middleware system with 50+ built-in middlewares
+- Middleware can be applied at Echo, Group, or individual route level
+- Common middleware: Logger, Recover, CORS, JWT, Rate Limiting, etc.
+
+### Key Patterns
+
+**Middleware Chain**
+- Pre-middleware runs before routing
+- Regular middleware runs after routing but before handlers
+- Middleware functions have signature `func(next echo.HandlerFunc) echo.HandlerFunc`
+
+**Route Groups**
+- Routes can be grouped with common prefixes and middleware
+- Groups support nested sub-groups
+- Defined in `group.go`
+
+**Data Binding**
+- Automatic binding of request data (JSON, XML, form) to Go structs
+- Implemented in `binder.go` with support for custom binders
+
+**Error Handling**
+- Centralized error handling via `HTTPErrorHandler`
+- Automatic panic recovery with stack traces
+
+## File Organization
+
+- Root directory: Core Echo functionality (echo.go, context.go, router.go, etc.)
+- `middleware/`: All built-in middleware implementations
+- `_test/`: Test fixtures and utilities
+- `_fixture/`: Test data files
+
+## Code Style
+
+- Go code uses tabs for indentation (per .editorconfig)
+- Follows standard Go conventions and formatting
+- Uses gofmt, golint, and staticcheck for code quality
+
+## Testing
+
+- Standard Go testing with `testing` package
+- Tests include unit tests, integration tests, and benchmarks
+- Race condition testing is required (`make race`)
+- Test files follow `*_test.go` naming convention

+### Supported Echo versions
-The benchmarks above were run on an Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz
+- Latest major version of Echo is `v5` as of 2026-01-18.
+ - Until 2026-03-31, any critical issues requiring breaking API changes will be addressed, even if this violates semantic versioning.
+ - See [API_CHANGES_V5.md](./API_CHANGES_V5.md) for public API changes between `v4` and `v5`, notes on upgrading.
+ - If you are using Echo in a production environment, it is recommended to wait until after 2026-03-31 before upgrading.
+- Echo `v4` is supported with **security*** updates and **bug** fixes until **2026-12-31**
-## [Guide](https://echo.labstack.com/guide)
### Installation

+# Development Guidelines for middlewares
+
+## Best practices:
+
+* Do not use `panic` in middleware creator functions in case of invalid configuration.
+* In case of an error in middleware function handling request avoid using `c.Error()` and returning no error instead
+ because previous middlewares up in call chain could have logic for dealing with returned errors.
+* Create middleware configuration structs that implement `MiddlewareConfigurator` interface so can decide if they
+ want to create middleware with panics or with returning errors on configuration errors.
+* When adding `echo.Context` to function type or fields make it first parameter so all functions with Context looks same.
