Three-Letter Name (tln)

The npm package registry is running out of three-letter names! The shortage has created a competitive environment for aspiring JavaScript library and framework creators. Today might be your last chance to claim your three-letter package name for your new incredible library/framework, but fear not - tln is here for you.

To generate your very own (still) available three-letter npm package name, simply run:

$ npx tln

It might take a second to find the perfect three-letter name for you, as most of them are already taken. But there, fgu is the exciting name of your new intriguing component library!

You can also generate multiple names at a time:

$ npx tln -n 6

Pass the -u flag to only get unique letters in names.

Or you can check the availability of any npm package name:

$ npx tln -c 'tln'
Name tln is taken:

For all possible options, run tln with the -h flag:

$ npx tln -h
tln - Generate available three-letter npm package names.

usage: tln
       tln [-n|--count] <count>
       tln [-c|--check] <name>
       tln [-h|--help]

    -n, --count <count>     The number of names to generate.
    -c, --check <name>      Check if NAME is an available package name on npm.
    -u, --unique-letters    Only generate names with unique letters.
    -h, --help              Show this message.

API Reference

For advanced usage, tln may be installed as a library using:

$ npm i tln

You may then use it inside ES Modules like so:

import { availableNames } from 'tln';
// ...
const myNames = await availableNames(3);
// ...

Or inside CommonJS modules:

const tln = require('tln');
// ...
const myNames = await tln.availableNames(3);
// ...


availableNames(count, options?)

Generate unique available names.

  • count: the number of names to be generated
  • options.uniqueLetters: a boolean, if true, only generate names, only containing unique letters (default: true)

Returns a Promise<string[]> of size count, containing the generated names.
