passport-sanity

Passport strategy for authenticating with Sanity using the OAuth 2.0 API.

This module lets you authenticate with Sanity.io in your Node.js applications. By plugging into Passport, Sanity.io authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-sanity

Usage

Create an Application

Before using passport-sanity, you must register an application with Sanity. Your application will be issued a client ID and client secret, which need to be provided to the strategy. You will also need to configure a callback URL which matches the route in your application.

Configure Strategy

The Sanity authentication strategy authenticates users using a Sanity account and OAuth 2.0 tokens. The client ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token, as well as profile which contains the authenticated user's Netilify profile. The verify callback must call cb providing a user to complete authentication.

const SanityStrategy = require('passport-sanity').Strategy;
 
passport.use(new SanityStrategy({
    clientID: SANITY_CLIENT_ID,
    clientSecret: SANITY_CLIENT_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/sanity/callback",
    state: true // use OAuth2 state param to protect against csrf attacks (requries express-session)
  },
  (accessToken, refreshToken, profile, cb) => {
    User.findOrCreate({provider: 'sanity': providerId: profile.id }, (err, user) => {
      return cb(err, user)
    })
  }
))

Note: While Sanity doesn't support refresh tokens (as for Jul. 2019), the verify callback still uses a second parameter refreshToken to conform to the OAuth2 standard. This makes it easier to share a verify callback function for all passport-oauth2 based authentications you use with Passport.js. The refreshToken will be undefined with this strategy, and should just be ignored.

Authenticate Requests

Use passport.authenticate(), specifying the 'sanity' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/sanity', passport.authenticate('sanity'))
 
app.get('/auth/sanity/callback', 
  passport.authenticate('sanity', { failureRedirect: '/login' }),
  (req, res) => {
    // Successful authentication, redirect home.
    res.redirect('/');
  })
