Quick Start

deno add jsr:@sandros94/deno-bundler

Usage Examples

# Basic usage
deno run -A jsr:@sandros94/deno-bundler

# With external packages
deno run -A jsr:@sandros94/deno-bundler \\
  --entrypoints="./main.ts" \\
  --external="h3,rendu"

# With string replacements
deno run -A jsr:@sandros94/deno-bundler \\
  --replace="Bunny.v1.serve=Bunny.v1.serve" \\
  --replace="Deno.env=Bun.env"

import { build } from "@sandros94/deno-bundler";

const result = await build({
  entrypoints: ["./main.ts"],
  external: ["h3", "rendu"],
  minify: true,
});

console.log(`Bundled in ${result.duration}ms`);
console.log(`Output files: ${result.outputFiles.join(", ")}`);

import { build } from "@sandros94/deno-bundler";

await build({
  entrypoints: ["./main.ts"],
  replace: {
    "Bunny.v1.serve": "Bunny.v1.serve",
    "Deno.env": "Bun.env",
  },
