Passport-Telegram

Passport strategy for authenticating with Telegram Messenger using the unofficial OAuth 2.0 API.

Note: this project is unofficial and is not affiliated with Telegram.

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

Installation

$ npm install passport-telegram

Usage

Getting credentials

First of all you need to sign in to telepass.me, register your application and obtain the APP_ID and APP_SECRET.

Configure Strategy

The Telegram authentication strategy authenticates requests by delegating to unofficial bridge using the OAuth 2.0 protocol.

Applications must supply a verify callback which accepts an accessToken, refreshToken and service-specific profile, and then calls the done callback supplying a user, which should be set to false if the credentials are not valid. If an exception occured, err should be set.

Options:

• clientID your application's App ID
• clientSecret your application's App Secret
• callbackURL URL to which the user will be redirected after granting authorization

Example

For more detailed example see the example folder.

 passport.use(
    new TelegramStrategy({
        clientID: '123-456-789',
        clientSecret: 'shhh-its-a-secret'
        callbackURL: 'https://www.example.net/auth/telegram/callback'
    },
    function(accessToken, refreshToken, profile, done) {
        User.findOrCreate(..., function (err, user) {
            done(err, user);
        });
    }
 ));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/telegram', 
    passport.authenticate('telegram'),
    function(req, res) {
        // The request will be redirected to telepass.me for authentication,
        // so this function will not be called.
    }
);
 
app.get('/auth/telegram/callback', 
    passport.authenticate('telegram', { failureRedirect: '/login' }),
    function(req, res) {
        // Successful authentication, redirect home.
        res.redirect('/');
    }
);
