@git.zone/tsbundle

A powerful multi-bundler tool supporting esbuild, rolldown, and rspack for painless bundling of web projects.

Installation

# Global installation for CLI usage
pnpm add -g @git.zone/tsbundle

# Local installation for project usage
pnpm add --save-dev @git.zone/tsbundle

Quick Start

Interactive Setup

The easiest way to get started is with the interactive wizard:

tsbundle init

This guides you through setting up your bundle configuration with preset options:

element - Web component / element bundle (./ts_web/index.ts -> ./dist_bundle/bundle.js)
website - Full website with HTML and assets (./ts_web/index.ts -> ./dist_serve/bundle.js)
npm - NPM package bundle (./ts/index.ts -> ./dist_bundle/bundle.js)
custom - Configure everything manually

Build Your Bundles

Once configured, simply run:

tsbundle

Your bundles will be built according to your smartconfig.json configuration.

CLI Commands

Command	Description
`tsbundle`	Build all bundles from `smartconfig.json` configuration
`tsbundle custom`	Same as above (explicit)
`tsbundle init`	Interactive wizard to create/update bundle configuration

Configuration

tsbundle uses smartconfig.json for configuration. Here's an example:

{
  "@git.zone/tsbundle": {
    "bundles": [
      {
        "from": "./ts_web/index.ts",
        "to": "./dist_bundle/bundle.js",
        "outputMode": "bundle",
        "bundler": "esbuild",
        "production": false
      },
      {
        "from": "./ts_web/index.ts",
        "to": "./dist_serve/bundle.js",
        "outputMode": "bundle",
        "bundler": "esbuild",
        "includeFiles": ["./html/**/*.html", "./assets/**/*"]
      }
    ]
  }
}

Bundle Configuration Options

Option	Type	Default	Description
`from`	`string`	-	Entry point TypeScript file
`to`	`string`	-	Output file path
`outputMode`	`"bundle"` \| `"base64ts"`	`"bundle"`	Output format (see below)
`bundler`	`"esbuild"` \| `"rolldown"` \| `"rspack"`	`"esbuild"`	Which bundler to use
`production`	`boolean`	`false`	Enable minification
`includeFiles`	`string[]`	`[]`	Glob patterns for additional files (HTML, assets)
`maxLineLength`	`number`	`0` (unlimited)	For `base64ts` mode: max chars per line in output

Output Modes

`bundle` (default)

Standard JavaScript bundle output. Additional files specified in includeFiles are copied to the output directory.

`base64ts`

Generates a TypeScript file with base64-encoded content - perfect for Deno compile scenarios where you need everything embedded in a single executable:

// Auto-generated by tsbundle
export const files: { path: string; contentBase64: string }[] = [
  { path: "bundle.js", contentBase64: "Y29uc3QgaGVsbG8gPSAid29ybGQi..." },
  { path: "index.html", contentBase64: "PCFET0NUWVBFIGh0bWw+..." },
];

If you're working with AI tools that have line length limitations, set maxLineLength (e.g., 200) to split long base64 strings across multiple lines.

Available Bundlers

tsbundle supports three modern bundlers, each with different strengths:

Bundler	Speed	Bundle Size	Best For
esbuild	Fastest	Medium	Development, quick iterations
rolldown	Fast	Smallest	Production builds, tree-shaking
rspack	Fast	Largest (webpack runtime)	Webpack compatibility

API Usage

TsBundle Class

The core bundling class, usable programmatically:

import { TsBundle } from '@git.zone/tsbundle';

const bundler = new TsBundle();

await bundler.build(
  process.cwd(),           // Working directory
  './src/index.ts',        // Entry point
  './dist/bundle.js',      // Output path
  {
    bundler: 'esbuild',    // 'esbuild' | 'rolldown' | 'rspack'
    production: true
  }
);

Each bundler runs in a separate child process via smartspawn.ThreadSimple, keeping the main process clean and isolated from bundler-specific dependencies.

HtmlHandler Class

Process and optionally minify HTML files:

import { HtmlHandler } from '@git.zone/tsbundle';

const htmlHandler = new HtmlHandler();

await htmlHandler.processHtml({
  from: './html/index.html',
  to: './dist/index.html',
  minify: true
});

AssetsHandler Class

Copy static assets between directories:

import { AssetsHandler } from '@git.zone/tsbundle';

const assetsHandler = new AssetsHandler();

await assetsHandler.processAssets({
  from: './assets',
  to: './dist/assets'
});

Base64TsOutput Class

Generate TypeScript files with base64-encoded content for embedding:

import { Base64TsOutput } from '@git.zone/tsbundle';

const output = new Base64TsOutput(process.cwd());
output.addFile('bundle.js', bundleBuffer);
await output.addFilesFromGlob('./html/**/*.html');
await output.writeToFile('./ts/embedded-bundle.ts', 200); // optional maxLineLength

CustomBundleHandler Class

Process multiple bundle configurations from smartconfig.json:

import { CustomBundleHandler } from '@git.zone/tsbundle';

const handler = new CustomBundleHandler(process.cwd());
const hasConfig = await handler.loadConfig();
if (hasConfig) {
  await handler.processAllBundles();
}

Embedding for Deno Compile

For single-executable scenarios with Deno:

tsbundle init
# Select "custom", set outputMode to "base64ts"

Config:

{
  "@git.zone/tsbundle": {
    "bundles": [
      {
        "from": "./ts_web/index.ts",
        "to": "./ts/embedded-bundle.ts",
        "outputMode": "base64ts",
        "bundler": "esbuild",
        "production": true,
        "includeFiles": ["./html/index.html"],
        "maxLineLength": 200
      }
    ]
  }
}

Then in your Deno app:

import { files } from './ts/embedded-bundle.ts';

// Decode and serve your embedded files
const bundle = files.find(f => f.path === 'bundle.js');
const html = files.find(f => f.path === 'html/index.html');

const bundleContent = atob(bundle.contentBase64);
const htmlContent = atob(html.contentBase64);
