Wasm build, made easy

• Build a set of code that can run seamlessly in Node.js, Deno, Bun, and browsers.
• No setup needed, just use directly.
• The generated package.json in pretty order.
• Add parameter validation to functions.

pnpm install -D wasmup

{
    // ...
    "scripts": {
        "build": "wasmup build --clean ."
    }
}

The Wasmup configuration file may be named any of the following:

• wasmup.config.js
• wasmup.config.cjs
• wasmup.config.mjs
• wasmup.config.ts
• wasmup.config.mts
• wasmup.config.cts
• wasmup.config.json

It should be placed in the root directory of your project and export an configuration objects. Here’s an example:

import { defineConfig } from "wasmup"

export default defineConfig({
    clean: true,
    output: "packages/toml-edit-js",
    scope: "rainbowatcher",
})

you can pass wasm-opt params by config in Cargo.toml, details ref to this link: cargo-toml-configuration

[package.metadata.wasm-pack.profile.release]
wasm-opt = [
    # Optimize level 4
    "-O4",
    # Run passes to convergence, continuing while binary size decreases
    "--converge",
    "--strip-debug",
    "--strip-dwarf",
    # flattens out code, removing nesting
    "--flatten",
    # inline small functions
    "--inlining",
    # removes unreachable code
    "--dead-code-elimination",
    "--minify-imports-and-exports-and-modules",
    # Grand Unified Flow Analysis
    "--gufa",
