passport-crypt-oauth20

Passport strategy for authenticating with CryPt using the OAuth 2.0 API.

This module lets you authenticate using CryPt in your Node.js applications.

Install

$ npm install passport-crypt-oauth20

Usage

Create An Application

Before using passport-crypt-oauth20, you must register an application with CryPt. If you have not already done so, a new application can be created in the CryPt Developers Console. Your application will be issued a client ID and client secret, which need to be provided to the strategy. You will also need to configure a redirect URI which matches the route in your application.

Configure Strategy

The CryPt authentication strategy authenticates users using a CryPt account and OAuth 2.0 tokens. The client ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's CryPt profile. The verify callback must call cb (done is used as cb in following code snippet) providing a user to complete authentication.

const CryPtStrategy = require('passport-crypt-oauth20')

passport.use(new CryPtStrategy({
         clientID: CONSUMER_CLIENT_ID,
         clientSecret: CONSUMER_CLIENT_SECRET,
         callbackURL: 'http://example.com/crypt/oauth/callback',
         scope:'profile'
       },
       function(accessToken, refreshToken, profile, done) {
        User.findOne({cryptId:profile.cryptId},(err,user)=>{
            if(err) throw err
            else if(user){return done(err,user)}
            else{
                User.create({...profile,
                    access_token:accessToken,
                    refersh_token:refreshToken
                },(error,userdoc)=>{
                    return done(error,userdoc)
                })
            }
        })
       }
     ));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/crypt/oauth/login',passport.authenticate('crypt'))

app.get('/crypt/oauth/callback', 
  passport.authenticate('crypt', { failureRedirect: '/loginfail',successRedirect:'/protected' }))
