passport-openid-oauth20

Passport strategy for authenticating with OpenID providers using the OAuth 2.0 API.

Install

npm install passport-openid-oauth20

Usage

Configure Strategy

The strategy requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's OpenID profile. The verify callback must call cb providing a user to complete authentication.

var OpenIdOAuth2Strategy = require("passport-openid-oauth20").Strategy;

// Example using Google OpenID profile.
passport.use(
  "google",
  new OpenIdOAuth2Strategy(
    {
      authorizationURL: "https://accounts.google.com/o/oauth2/v2/auth",
      tokenURL: "https://www.googleapis.com/oauth2/v4/token",
      userProfileURL: "https://www.googleapis.com/oauth2/v3/userinfo",
      clientID: GOOGLE_CLIENT_ID,
      clientSecret: GOOGLE_CLIENT_SECRET,
      callbackURL: "https://www.example.net/auth/google/callback"
    },
    function(accessToken, refreshToken, profile, cb) {
      User.findOrCreate(
        { providerId: profile.id, provider: profile.provider },
        function(err, user) {
          return cb(err, user);
        }
      );
    }
  )
);

Authenticate Requests

Use passport.authenticate(), specifying the strategy name, or 'openid-oauth20', to authenticate requests.

For example, as route middleware in an Express application:

app.get(
  "/auth/google",
  passport.authenticate("google", { scope: ["profile"] })
);

app.get(
  "/auth/google/callback",
  passport.authenticate("google", { failureRedirect: "/login" }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect("/");
  }
);
