Welcome to the Ultimate Guide to npm-name

npm-name is an incredibly powerful tool designed to help developers manage their Node.js projects. By using npm-name, you can effectively handle package dependencies, run scripts, and publish your own packages to the npm registry. This guide provides an extensive overview of the npm-name API with practical examples to get you started.

Installing npm-name

  npm install npm-name

Examples of npm-name API

1. Checking if a Package Name is Available

  const npmName = require('npm-name');
  (async () => {
      console.log(await npmName('unicorn')); // false
      console.log(await npmName('abcxyz'));   // true
  })();

2. Checking Multiple Package Names

  const npmName = require('npm-name');
  (async () => {
      const result = await npmName.many(['react', 'angular', 'vue']);
      console.log(result);
      // {react: false, angular: false, vue: false}
  })();

3. Checking Package Name with Options

  const npmName = require('npm-name');
  (async () => {
      console.log(await npmName('npm-name', {timeout: 5000}));
  })();

4. Using a Proxy

  const npmName = require('npm-name');
  (async () => {
      console.log(await npmName('lodash', {proxy: 'http://localhost:8123'}));
  })();

Building a Simple App Using npm-name

Here is a simple Node.js application that integrates the npm-name API to help users verify the availability of package names:

  const express = require('express');
  const npmName = require('npm-name');

  const app = express();
  const port = 3000;

  app.get('/check-package/:name', async (req, res) => {
      const packageName = req.params.name;
      const isAvailable = await npmName(packageName);
      res.send(`The package name "${packageName}" is ${isAvailable ? 'available' : 'not available'}.`);
  });

  app.listen(port, () => {
      console.log(`Example app listening at http://localhost:${port}`);
  });

This application sets up a simple Express.js server that checks the availability of an npm package name when a GET request is made to the /check-package/:name endpoint.

That’s all for the npm-name guide. Happy coding!
