Tauque (pronounced /tɔːk/, like torque) is a zero-configuration JS/TS bundler with serious pulling power. It uses esbuild under the cover, meaning it transpiles up to 100x quicker than Rollup/Webpack with Babel.

Install:

npx install-tauque

Create a dist folder with bundles (no-config needed):

npm run dev

Tauque can bundle

• JavaScript (with optional transpilation)
• TypeScript
• JSX
• CSS (files and js imports)
• JSON

Dev mode watching for file changes and running cumulative builds, most taking around 10ms:

Install

Install Tauque on a project that's already set up, and it'll take your entry point from package.json (or try to find it elsewhere) and automatically create a config file that's ready to run.

npx install-tauque

Ready to go!

Tauque is now ready to run. Bundles will be written to the dist folder by default. Run tauque dev mode with:

npm run dev

A single time build can also be run with:

npm run build

Alternative install

You can also Tauque without building config and readme files:

npm install tauque

Config options

A tauque.json config file will automatically be generated when you first install Tauque. This should be placed alongside package.json in your project root.

All config options, with default settings:

// Name of the final file (required)
"name": "packageName"

// Location of the entry point (required)
"source": "src/index.js",

// Package type: "module" (also "esm"); "browser" (also "iife"); "node" (also "cjs"); "all"
"type": "all",

// Global variable name of export in browser/iife packages
"global": "packageName",

// Directory for output package
"outputDir": "dist",

// Directory to watch for changes
"watchDir": "src",

// Target environment, eg: ["es2020", "chrome58", "firefox57", "node12.19.1"]
"target": ["es6"],

// Bundle imports: true, false
"bundle": true,

// Minify package: true, false
"minify": true,

// Generate separate source map file
"sourceMap": true,

// Automatically add environment variables
"useEnvVariables": true,

// Native esbuild settings to pass on (overrides Tauque)
"esbuild": {}
