An HTTP client driven by Kotlin scripts.

Example:

// Basic GET Request
GET("https://api.example.com/users") {
  header("Authorization", "Bearer token123")
  queryParam("limit", 10)
}

//POST Request with JSON Body
POST("https://api.example.com/users") {
  contentType("application/json")
  body(
    """
        {
            "name": "John Doe",
            "email": "john@example.com"
        }
        """
  )
}

// Handling Responses
GET("https://api.example.com/users/1") then {
  val userData = jsonPath().json<Map<String, Any>>()
  assertEquals("John Doe", userData["name"])
}

// Store value into variable
val userId: String by POST("https://api.example.com/users") {
  contentType("application/json")
  body("""{"name": "John Doe"}""")
}.then {
  userId.set(jsonPath().read("$.id"))
}

// Use value from another request using variable
GET("https://api.example.com/users/$userId")

The Connekt installer sets up a CLI tool that allows you to run Kotlin scripts inside a Dockerized runtime with environment support.

• Downloads the Connekt launcher script (bash or batch version)

• Installs it into your home directory at:

  • ~/.connekt (Linux/MacOS)
  • %USERPROFILE%\.connekt (Windows)

• Adds ~/.connekt or %USERPROFILE%\.connekt to your PATH if needed

• Makes the connekt command available in your terminal

• Does not download Docker images during install — images are pulled lazily on first script run

curl -sSf https://raw.githubusercontent.com/Amplicode/connekt/main/install/install.sh | bash

curl -fsSL https://raw.githubusercontent.com/Amplicode/connekt/main/install/install.bat -o %TEMP%\install-connekt.bat && %TEMP%\install-connekt.bat

connekt my-script.kts

• Docker must be installed and running

• curl must be available (preinstalled on macOS, most Linux, and Windows 10+)

• On Windows:

  • Use CMD, PowerShell, or Git Bash
  • connekt.bat is used under the hood

You can run any .kts or .connekt.kts script with the connekt command.

Pull Connekt Docker container:

docker pull ghcr.io/amplicode/connekt:0.2.10

Run container:

docker run --rm \
  --add-host=host.docker.internal:host-gateway \
  -v /absolute/path/to/your/scripts:/connekt/scripts \
  -v /absolute/path/to/connekt.env.json:/connekt/scripts/connekt.env.json \
  ghcr.io/amplicode/connekt:0.2.10 \
  --env-name=dev \
  --env-file=scripts/connekt.env.json \
  --script=scripts/your_script_name.cnt.kt \
  --env-param param1=value1 \
  --env-param param2=value2

Connekt consists of two main modules:

1. Connekt Script Definition: A Kotlin scripting library that provides a domain-specific language (DSL) for defining HTTP requests, handling responses, and managing state between requests.

2. Connekt Scripting Host: A command-line tool and runtime environment for executing Connekt scripts. It can be run directly or as a Docker container.

• Kotlin Scripting: Write scripts with the .connekt.kts extension using Kotlin's scripting capabilities
• HTTP Methods: Support for all standard HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, TRACE)
• Request Configuration:
  • Headers
  • Query parameters
  • Path parameters
  • Request body (JSON, text, form data, multipart)
  • Cookies
  • SSL/TLS configuration
• Response Handling:
  • JSON parsing with JSONPath
  • Response validation
  • File downloads
• Handling Authorization
  • OAuth2 Authorization Code
• State Management:
  • Variables store for sharing data between requests
  • Environment configuration
• Use Cases: Group related requests into use cases for better organization
• Dependency Management: Add Maven dependencies to your scripts

1. Clone the repository
2. Build the project:

./gradlew build

1. Run the application:

./gradlew :connekt-scripting-host:run --args="path/to/your/script.connekt.kts"

• connekt-script-definition: Core library that defines the DSL for HTTP requests
• connekt-scripting-host: Command-line tool and runtime environment for executing scripts
