Manifest

The project manifest (rfw.json) defines build options and plugin configuration. Running rfw init generates this file with build.type set to ssc by default.

build.type

Controls the build mode:

• unset → standard Wasm build
  
• ssc → enables Server-Side Computed builds and compiles host components
  

{
  "build": {
    "type": "ssc"
  }
}

plugins

The plugins section lists build plugins, each with its own configuration.

Tailwind CSS

Generate stylesheets using the Tailwind CLI:

{
  "plugins": {
    "tailwind": {
      "input": "input.css",
      "output": "tailwind.css",
      "minify": true
    }
  }
}

• input: source file with @import "tailwindcss" directives (Tailwind v4)
  
• output: compiled CSS file (default: tailwind.css)
  
• minify: set false to disable minification
  
• args: extra CLI arguments for tailwindcss
  

Environment Variables

Expose variables prefixed with RFW_ through the generated rfwenv package.

{
  "plugins": {
    "env": {}
  }
}

Static Assets

Copy files from a directory into the build:

{
  "plugins": {
    "assets": {
      "dir": "public",
      "dest": "dist"
    }
  }
}

• dir: source directory (default: assets)
  
• dest: output folder (default: dist)
  

Copy Files

Copy files based on glob patterns:

{
  "plugins": {
    "copy": {
      "files": [
        { "from": "examples/**/*", "to": "build/static/examples" }
      ]
    }
  }
}

Plugins run during rfw build and also watch files in development.
