This module lets you authenticate using Topcoder in your Node.js applications. By plugging into Passport, Topcoder authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
$ npm install passport-topcoder
The Topcoder authentication strategy authenticates users using a Topcoder account
and OAuth tokens. The strategy requires a verify callback function, which receives the
access token and corresponding refresh token as arguments, along with a profile which
contains the authenticated user's Topcoder profile. The verify callback must
call done providing a user to complete authentication.
In order to identify your application to TopCoder, specify the client id,
client secret, and callback URL within options.
passport.use(new TopcoderStrategy({
clientID: MY_CLIENT_ID,
clientSecret: MY_CLIENT_SECRET,
callbackURL: MY_CALLBACK_URL
},
function(accessToken, refreshToken, params, profile, done) {
var tokenDTO = {
accessToken: accessToken,
expirationTime : params.expires_in,
scope : params.scope.split(" ")
};
return done(null, tokenDTO);
}
));
Use passport.authenticate(), specifying the 'Topcoder' strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/topcoder', passport.authenticate('Topcoder', {scope: ["FORUMS_REST", "CONTEST_REST"]}));
app.get('/auth/topcoder/callback', function (req, res, next) {
passport.authenticate('Topcoder', function (err, token) {
if (req.query.error) {
res.render("login", {error: req.query.error});
} else {
res.render("login", {token: token});
}
})(req, res, next);
});
