A package that makes using the OAuth2 PKCE flow easier

Installation

npm i js-pkce

Create a new instance

Create a new instance of js-pkce with all of the details needed.

import PKCE from 'js-pkce';
const pkce = new PKCE({
  client_id: 'myclientid',
  redirect_uri: 'http://localhost:8080/auth',
  authorization_endpoint: 'https://authserver.com/oauth/authorize',
  token_endpoint: 'https://authserver.com/oauth/token',
  requested_scopes: '*',
});

Start the authorization process

Typically you just need to go to the authorization url to start the process. This example is something that might work in a SPA.

window.location.replace(pkce.authorizeUrl());

Trade the code for a token

After logging in with the authorization server, you will be redirected to the value in the redirect_uri parameter you set when creating the instance. Again, this is an example that might work for a SPA.

When you get back here, you need to exchange the code for a token.

const url = window.location.href;
pkce.exchangeForAccessToken(url).then((resp) => {
  const token = resp.access_token;
  // Do stuff with the access token.
});
