The 'raindrop' strategy authenticates a user by confirming the user has input an API-generated message into the Hydro mobile app.
$ npm install passport-raindrop
The verify callback is required to verify a valid site user is being authenticated. Authentication
fails if no user is found.
const passport = require('passport'),
RaindropStrategy = require('passport-raindrop')
// Initialize the raindrop. Declared as a variable in order to access Raindrop SDK functions later.
let raindrop = new RaindropStrategy({
environment: ENVIRONMENT,
clientId: CLIENT_ID,
clientSecret: CLIENT_SECRET,
applicationId: APPLICATION_ID
}, function (authUser, done) {
// This verifies the user and returns it to the authentication
let user = userDB.find(usr => usr.hydroId === authUser.hydroId);
return user ? done(null, user) : done(new Error('User not found.'), null);
});
// Pass the strategy into passport
passport.use(raindrop);
Use passport.authenticate() and specify the 'raindrop' strategy.
passport.authenticate('raindrop', {
successRedirect: '/pass',
failureRedirect: '/fail'
})(req, res, next);
let message = HydrogenAPI.raindrop.generateMessage();
In this example HydrogenAPI is the export from the above 'Configuration'. See the 'Complete Example' below for the full
