OAuth 2.0 Client Package

Description

This is a simple OAuth 2.0 Client package in JavaScript, designed to facilitate the authentication process with an OAuth 2.0 provider. It supports the password and refresh token grant types.

Installation

Before using this package, ensure you have the axios library installed. You can install it using the following command:

npm install axios
npm install oauth-client-package

## USAGE
const OAuthClient = require('oauth-client-package');

// Create an instance of the OAuthClient with your OAuth 2.0 credentials and token endpoint.
const oauthClient = new OAuthClient({
  clientId: 'your_client_id',
  clientSecret: 'your_client_secret',
  tokenEndpoint: 'https://example.com/token',
});

// Example usage for obtaining an access token using the password grant type:
const username = '[email protected]';
const password = 'user_password';

oauthClient.getAccessToken(username, password)
  .then((accessToken) => {
    console.log('Access Token:', accessToken);
  })
  .catch((error) => {
    console.error('Error:', error.message);
  });

// Example usage for refreshing an access token using the refresh token grant type:
const refreshToken = 'your_refresh_token';

oauthClient.refreshToken(refreshToken)
  .then((accessToken) => {
    console.log('Refreshed Access Token:', accessToken);
  })
  .catch((error) => {
    console.error('Error:', error.message);
  });
