Bundle

The Bundle resource uses esbuild to bundle JavaScript and TypeScript files into optimized output.

Minimal Example

Bundle a TypeScript file into an ESM module:

import { Bundle } from "alchemy/esbuild";

const bundle = await Bundle("handler", {
  entryPoint: "src/handler.ts",
  format: "esm"
});

Node.js Bundle

Bundle a file specifically for Node.js with sourcemaps:

import { Bundle } from "alchemy/esbuild";

const bundle = await Bundle("api", {
  entryPoint: "src/api.ts",
  format: "cjs",
  platform: "node", 
  target: "node18",
  sourcemap: true,
  external: ["aws-sdk"]
});

Browser Bundle

Create a minified browser bundle:

import { Bundle } from "alchemy/esbuild";

const bundle = await Bundle("app", {
  entryPoint: "src/app.ts",
  outfile: "dist/app.min.js",
  format: "iife",
  platform: "browser",
  target: ["es2020", "chrome58"],
  minify: true
});
