Usage

#### Configure Strategy

The strategy supports authentication with comprehensive user profile data and refresh tokens:

`javascript
const passport = require('passport');
const TwitterStrategy = require('passport-twitter-oauth2-ravigaai');

passport.use(new TwitterStrategy({
clientID: TWITTER_CLIENT_ID,
clientSecret: TWITTER_CLIENT_SECRET,
callbackURL: "http://localhost:3000/auth/twitter/callback",
scope: [
'tweet.read',
'users.read',
'offline.access', // For refresh tokens
'email' // For email access (if granted by user)
],
// Optional configuration
state: true, // Enable CSRF protection (default: true)
pkce: true, // Enable PKCE (default: true)
profileFields: 'description,entities,id,location,name,pinned_tweet_id,profile_image_url,protected,public_metrics,url,username,verified,verified_type,withheld'
},
function(accessToken, refreshToken, profile, cb) {
// Available profile data:
// - Basic: id, username, displayName
// - Photos: profile.photos[0].value (profile image URL)
// - Profile: description, location, url
// - Status: verified, verifiedType, protected
// - Metrics: followers, following, etc. (in profile.metrics)
User.findOrCreate({
twitterId: profile.id,
username: profile.username,
displayName: profile.displayName,
profileImage: profile.photos?.[0]?.value,
refreshToken // Store securely
}, function (err, user) {
return cb(err, user);
});
}
));
`

#### Security Options

The strategy provides two security features that can be configured:

1. State Parameter (CSRF Protection):
`javascript
{
state: true // Enable state parameter (default: true)
// or
state: false // Disable state parameter if you want to handle CSRF protection yourself
}
`

2. PKCE (Proof Key for Code Exchange):
`javascript
{
pkce: true // Enable PKCE (default: true)
// or
pkce: false // Disable PKCE if you need to handle it differently
}
`

Note: It's recommended to keep both security features enabled unless you have a specific reason to handle them differently.

#### Authentication Routes

`javascript
// Initialize authentication
app.get('/auth/twitter',
passport.authenticate('twitter', {
scope: ['tweet.read', 'users.read', 'offline.access', 'email']
}));

// Handle callback
app.get('/auth/twitter/callback',
passport.authenticate('twitter', { failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
`

Profile Fields

The strategy returns a rich user profile that may include:

- id: The user's Twitter ID
- username: The user's Twitter handle
- displayName: The user's display name
- photos: Array of profile images (if available)
- description: User's bio
- location: User's location
- verified: Verification status
- verifiedType: Type of verification
- metrics: Public metrics (followers, following, etc.)
- url: User's website
- protected: Protected tweet status

Note: Some fields may be undefined if the user hasn't set them or if the required scopes aren't granted.

Refresh Token Support

To enable refresh token support:

1. Add the offline.access scope to your authentication request
2. Store the refresh token securely when received
3. Use the refresh token to obtain new access tokens when needed

Example implementation in the callback:

`javascript
passport.use(new TwitterStrategy({
clientID: TWITTER_CLIENT_ID,
clientSecret: TWITTER_CLIENT_SECRET,
callbackURL: "http://localhost:3000/auth/twitter/callback",
scope: ['tweet.read', 'users.read', 'offline.access']
},
async function(accessToken, refreshToken, profile, cb) {
try {
// Store tokens securely
const user = await User.findOrCreate({
twitterId: profile.id,
accessToken,
refreshToken // Store securely for future use
});
return cb(null, user);
} catch (err) {
return cb(err);
}
}
));
