Build System

The relayer uses esbuild for fast bundling into a single IIFE file.

Command​

node build.mjs

Output​

dist/
├── relayer.iife.js      ← injectable bundle
└── relayer.iife.js.map  ← source map

Config highlights​

// build.mjs
await esbuild.build({
  entryPoints: ['src/index.ts'],
  bundle: true,
  format: 'iife',       // Self-executing — no module system required
  platform: 'browser',
  target: ['es2020'],
  outfile: 'dist/relayer.iife.js',
  sourcemap: true,
  alias: {
    events: 'eventemitter3',
    crypto: './src/polyfills/crypto.js',
  },
  define: {
    global: 'globalThis',
    'process.env.NODE_ENV': '"production"',
  },
});

The iife format wraps everything in a self-executing function, making it safe to inject into any page without polluting the global namespace (except for window.ethereum).
