Note: This package is a working npm library template. Use it as a starting point and replace the sample package identity and API before publishing your own library. Follow Customize This Template after forking or copying the project.

mazey-npm-template

A TypeScript template for publishing npm packages in CJS, ESM, and browser formats.

• Project website
• Live playground
• API documentation

Installation

Use mazey-npm-template via npm.

npm install mazey-npm-template

For direct browser usage, load the published lib/mazey-npm-template.min.js IIFE bundle.

Quick Start

import { createGreeting } from "mazey-npm-template";

const message = createGreeting("Cheng");

console.log(message); // "Hello, Cheng!"

Usage

ESM And TypeScript

Import runtime values and public types from the package root:

import { createGreeting, type CreateGreetingOptions } from "mazey-npm-template";

const options: CreateGreetingOptions = {
  punctuation: ".",
};

console.log(createGreeting("community", options)); // "Hello, community."

CommonJS

const { createGreeting } = require("mazey-npm-template");

console.log(createGreeting("CommonJS")); // "Hello, CommonJS!"

Browser Script

Load the IIFE bundle directly from a CDN when a package manager or bundler is not available:

<script src="https://cdn.jsdelivr.net/npm/mazey-npm-template/lib/mazey-npm-template.min.js"></script>
<script>
  const { createGreeting } = MAZEY_NPM_TEMPLATE;

  document.querySelector("#message").textContent = createGreeting("browser");
</script>

Pin an exact package version in the CDN URL for production applications.

API Reference

createGreeting(name, options?)

Creates a greeting and returns it as a string.

| Parameter | Type | Description | | --------------------- | ----------------------- | ---------------------------------------------- | | name | string | Name included in the greeting. | | options | CreateGreetingOptions | Optional output formatting. | | options.punctuation | string | Final punctuation. Defaults to an exclamation. |

Whitespace is trimmed from name. A blank name falls back to "friend".

createGreeting("Cheng"); // "Hello, Cheng!"
createGreeting("  team  ", { punctuation: "." }); // "Hello, team."
createGreeting("   "); // "Hello, friend!"

The generated API documentation describes the complete public surface.

Package Formats

| Consumer | Package condition | Published file | | ------------------ | ----------------------- | ------------------------------- | | ESM and bundlers | exports.import | lib/index.esm.js | | Node.js CommonJS | exports.require | lib/index.cjs | | Browser/CDN | unpkg | lib/mazey-npm-template.min.js | | TypeScript tooling | exports.types/types | lib/index.d.ts |

Source maps are generated for all JavaScript bundles. The root declarations also load the published browser type augmentations from lib/global.d.ts.

Development

Repository workflows use Node.js 22. Install dependencies and start the example development server:

npm install
npm run dev

The project website is served at http://localhost:8080/. The playground is available at http://localhost:8080/playground/ and imports the public API directly from src.

Package metadata remains in package.json. A package-safe helper derives bundle names without loading website settings, while shared repository, website, theme, SEO, and PWA settings flow through project.config.js. See Customize This Template for the post-fork checklist.

Generate the complete GitHub Pages artifact, including the website, playground, API documentation, robots.txt, and sitemap.xml:

npm run docs
npm run seo:validate
npm run pwa:validate

The deployed crawler files are /mazey-npm-template/robots.txt and /mazey-npm-template/sitemap.xml.

Add The Website To Your Device

The project website is a Progressive Web App scoped to /mazey-npm-template/. Supported Chrome and Edge browsers may show their own install icon or the site's Install app action when the browser exposes an install prompt. Other browsers may require installation through their menus. On iPhone and iPad, Safari users can choose Share, then Add to Home Screen; its capabilities are not identical to a Chrome installation.

Installed standalone mode keeps Home, Playground, Install, Usage, API, GitHub, and npm navigation available. Adding the website to your device and the browser Fullscreen API are separate capabilities, so using the standalone app does not guarantee native fullscreen support.

Build and serve a production-like local PWA at http://127.0.0.1:4173/mazey-npm-template/:

npm run pwa:preview

Normal npm run dev does not register the production service worker. When testing worker updates, use the browser's Application tools to unregister older workers or clear site data before a clean install. Do not open generated HTML directly from the filesystem; service workers require HTTPS or a trusted local origin such as localhost.
