Passport-LINE (passport-line)

Passport strategy for authenticating with LINE using the OAuth 2.0 API. (Updated to support LINE Login v2.1)

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

Install

$ npm install passport-line

Usage

Configure Strategy

The LINE authentication strategy authenticates users using a LINE 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 channelID, channelSecret, and callback URL.

passport.use(new LineStrategy({
    channelID: YOUR LINE CHANNEL ID,
    channelSecret: YOUR LINE CHANNEL SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/line/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ id: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/line',
  passport.authenticate('line'));

app.get('/auth/line/callback', 
  passport.authenticate('line', { failureRedirect: '/login', successRedirect : '/' }));
