JavaScript Boilerplate Generator
Scaffold a starter JavaScript (or TypeScript) file — pick a module format (ESM, CommonJS, UMD, IIFE) and a skeleton (class, singleton, module pattern, tiny event emitter, state store, debounce/throttle, fetch wrapper, Web Component, DOM-ready) with strict mode, JSDoc, exports and error handling toggled to taste.
What this tool does
It writes the boilerplate at the top of a new JavaScript file for you — the module wrapper, a chosen skeleton, and the small conventional extras — so you can start on the actual logic.
Module formats
ES module (import /
export) for modern code. CommonJS
(require / module.exports) for older Node.
UMD works as ESM, CJS or a browser global.
IIFE is a self-contained browser script.
Skeletons
Empty, class, singleton, the module (revealing) pattern, a tiny
on/off/emit event emitter, a subscribe-based state store,
a debounce + throttle pair, a
fetch wrapper with a timeout and JSON handling, a
customElements Web Component, and a DOM-ready wrapper.
Extras
'use strict' where it applies, a JSDoc
@fileoverview header, named or default export, a
CONFIG object, and a top-level try/catch.
Privacy
Everything runs in your browser. Nothing is uploaded.
