Username Checker

The Username Checker allows you to check the availability of a username across multiple websites.

Installation

npm install username-checker --save

Usage

To use the Username Checker, you first need to import the package.

import { UsernameChecker } from 'username-checker';

OR

const { UsernameChecker } = require('username-checker');

Create an instance of the UsernameChecker class and then use the isAvailable method to check the availability of a username on a specific website:

const usernameChecker = new UsernameChecker();
const result = usernameChecker.isAvailable('twitter', 'my-desired-username');
console.log(result); // { service: 'twitter', url: 'https://github.com/my-desired-username', available: true }

The isAvailable method takes two arguments - the website name (as a string) and the username to check (also a string). The method returns a Promise that resolves to an object containing information about the availability of the username on the specified website. The object has the following properties:

• service - the name of the website checked.
• url - the URL used to check the username.
• available - a boolean value indicating whether the username is available on the website. This could also be undefined in case there was no deterministic way to deduce the availability.
• reason - A potential reason of what could have gone wrong that resulted in available = undefined.

The getServices method returns an array of supported website names:

const services = usernameChecker.getServices();
console.log(services); // ['github', 'twitter', 'instagram', ... ]
