A list of all the public package names on npm.

• Includes scoped packages
• Updated daily

Installation

1npm install all-the-package-names --save

Usage

The module exports a big flat array of package names:

1const names = require("all-the-package-names")
2
3names.includes('superagent')
4// => true
5
6// Check if a given package name exists
7names.includes('crazy-new-package-name')
8// => false
9
10names.length
11// => 286289
12
13names.filter(name => name.includes('banana'))
14// => [ 'banana', 'banana-banana', 'banana-split', ...]
15
16// Note: This example requires node 4 or greater because it uses
17// const, arrow functions, and the `includes` array/string helper.

CLI Usage

You can also use it on the command line. Newline-delimited names are piped to STDOUT:

1npm i -g all-the-package-names
2all-the-package-names | grep spell

⚠️ Gotchas

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:

1const names = require('all-the-package-names')
2  .filter(name => name === name.toLowerCase())

Tests

1npm install
2npm test
