This is a
playground to test code. It runs a full
Node.js environment and already has all of
npm’s 400,000 packages pre-installed, including
all-the-package-names with all
npm packages installed. Try it out:

A list of all the public package names on npm.
npm install all-the-package-names --save
The module exports a big flat array of package names:
const names = require("all-the-package-names") // Most-depended-on names are first. See what's popular! names.slice(0,5) // [ // 'mocha', // 'chai', // 'lodash', // 'grunt', // 'eslint' // ] names.includes('superagent') // => true // Check if a given package name exists names.includes('crazy-new-package-name') // => false names.length // => 286289 names.filter(name => name.includes('banana')) // => [ 'banana', 'banana-banana', 'banana-split', ...] // Note: This example requires node 4 or greater because it uses // const, arrow functions, and the `includes` array/string helper.
You can also use it on the command line. Newline-delimited names are piped to STDOUT:
npm i -g all-the-package-names all-the-package-names | grep spell
Note that while mixed-case package names are no longer allowed to be published to the npm registry, there are over 2800 legacy mixed-case packages, many of which have the same spelling as other existing lowercase packages. See nice-registry/mixed-case-package-names for the the full list.
To avoid the mixed-case names when working with this data, just filter them out:
const names = require('all-the-package-names') .filter(name => name === name.toLowerCase())
npm install npm test
