Chalkable (OAuth2) authentication strategies for Passport.


Passport strategies for authenticating with Chalkable using OAuth 2.0.

This module lets you authenticate using Chalkable in your Node.js applications. By plugging into Passport, Chalkable authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

$ npm install passport-chalkable-oauth2

The Chalkable OAuth 2.0 authentication strategy authenticates users using a Chalkable account and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a client ID, client secret, and callback URL.

var ChalkableStrategy = require('passport-chalkable-oauth2').OAuth2Strategy;

passport.use(new ChalkableStrategy({
    callbackURL: ""
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ chalkableId: }, function (err, user) {
      return done(err, user);

Use passport.authenticate(), specifying the 'chalkable' strategy, to authenticate requests.

For example, as route middleware in an Express application:

  passport.authenticate('chalkable', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
