The Snapchat authentication strategy authenticates requests by delegating to Snapchat 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 cb 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 Snapchat application's App ID
• clientSecret your Snapchat application's App Secret
• callbackURL URL to which Snapchat will redirect the user after granting authorization
• profileFields array of fields to add to query. Valid fields are 'id', 'displayName', 'bitmoji'.
• scope array of scopes. Valid scopes are 'user.display_name' & 'user.bitmoji.avatar'.

Examples:

  passport.use(new SnapchatStrategy({
      clientID: '123-456-789', // process.env.clientID
      clientSecret: 'shhh-its-a-secret', // process.env.clientSecret
      callbackURL: 'https://www.example.net/auth/Snapchat/callback',
      profileFields: ['id', 'displayName', 'bitmoji'],
      scope: ['user.display_name', 'user.bitmoji.avatar'],
    },
    function(accessToken, refreshToken, profile, cb) {
      User.findOrCreate(..., function (err, user) {
        cb(err, user);
      });
    }
  ));
