[Passport](http://passportjs.org/) strategy for authenticating with Twitter using [OAuth 2.0](https://developer.twitter.com/en/docs/authentication/oauth-2-0).

This module lets you authenticate using Twitter in your Node.js applications.
By plugging into Passport, Twitter authentication can be integrated into any application or framework that supports
[Connect](http://www.senchalabs.org/connect/)-style middleware, including
[Express](http://expressjs.com/).

[Twitter announced OAuth 2.0 general availability](https://twittercommunity.com/t/announcing-oauth-2-0-general-availability/163555) on December 14 2021 and encourages developers to use Twitter API v2.0 with OAuth 2.0 authentication.

Twitter OAuth 2.0 implementation specifics:

- [PKCE](https://datatracker.ietf.org/doc/html/rfc7636) is required
- OAuth2 client credentials must be passed via `Authorization` header for `confidential` client types

## Install

```shell
npm install @superfaceai/passport-twitter-oauth2
```

## Usage

> **Note**
> Check our blog for a [complete tutorial with code explanation](https://superface.ai/blog/twitter-oauth2-passport?ref=github-passport-twitter-oauth2).

#### Create an Application

Before using `@superfaceai/passport-twitter-oauth2`, you must register a project and an application with Twitter by following these steps:

1. go to https://developer.twitter.com/ and either sign up for a new account or sign in with existing one
1. sign up for Essential access; you will need to verify a phone number for your Twitter account
1. create a project and application (Essential account is limited to a single project and application)
1. in application settings generate OAuth 2.0 Client ID and Client Secret; mind that you cannot view the secret again later, only regenerate it

#### Configure Strategy

Provide OAuth 2.0 Client ID and Client Secret (from previous step)
to the strategy constructor. The strategy
also requires a `verify` callback, which receives the access token and
refresh token as arguments, as well as `profile` which contains the
authenticated user's Twitter profile. The `verify` callback must call `cb`
providing a user to complete authentication.

```javascript
passport.use(
new TwitterStrategy(
{
clientType: 'confidential', //depends on your Twitter app settings, valid values are `confidential` or `public`
clientID: TWITTER_CLIENT_ID,
clientSecret: TWITTER_CLIENT_SECRET,
callbackURL: 'http://127.0.0.1:3000/auth/twitter/callback',
},
function (accessToken, refreshToken, profile, done) {
User.findOrCreate({ twitterId: profile.id }, function (err, user) {
return done(err, user);
});
}
)
);
```

#### Authenticate Requests

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

Do not forget to configure scopes required by your application.

For example, you can use `authenticate` function as an Express route middleware:

```javascript
app.get('/auth/twitter', passport.authenticate('twitter'));

app.get(
'/auth/twitter/callback',
passport.authenticate('twitter', {
failureRedirect: '/login',
scope: ['tweet.read', 'tweet.write', 'users.read'],
}),
function (req, res) {
// Successful authentication, redirect home.
res.redirect('/');
}
);
```
