Passport strategy for authenticating with EchoSign using the OAuth 2.0 API.
This module lets you authenticate using EchoSign in your Node.js applications. By plugging into Passport, EchoSign authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
The EchoSign authentication strategy authenticates users using a EchoSign
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 app ID, app secret, and callback URL.
passport.use(new EchoSignStrategy({
clientID: ECHOSIGN_APP_ID,
clientSecret: ECHOSIGN_APP_SECRET,
callbackURL: "http://localhost:3000/auth/echosign/callback"
}, function (accessToken, refreshToken, profile, done) {
// store credentials, etc
});
}
));
Use passport.authenticate(), specifying the 'echosign' strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/echosign', passport.authenticate('echosign'));
app.get('/auth/echosign/callback',
passport.authenticate('echosign', { failureRedirect: '/login' }),
function(req, res) {
// Successul authentication, redirect home.
res.redirect('/');
});
