Twitter

OAuth 2.0 provider for Twitter API v2.

Also see the OAuth 2.0 with PKCE guide.

Initialization

Pass the client secret for confidential clients.

import * as arctic from "arctic";

const twitter = new arctic.Twitter(clientId, clientSecret, redirectURI);
const twitter = new arctic.Twitter(clientId, null, redirectURI);

Create authorization URL

import * as arctic from "arctic";

const state = arctic.generateState();
const scopes = ["account_info.read", "files.content.read"];
const url = twitter.createAuthorizationURL(state, codeVerifier, scopes);

Validate authorization code

validateAuthorizationCode() will either return an OAuth2Tokens, or throw one of OAuth2RequestError, ArcticFetchError, UnexpectedResponseError, or UnexpectedErrorResponseBodyError. Twitter returns an access token and its expiration.

import * as arctic from "arctic";

try {
	const tokens = await twitter.validateAuthorizationCode(code, codeVerifier);
	const accessToken = tokens.accessToken();
	const accessTokenExpiresAt = tokens.accessTokenExpiresAt();
} catch (e) {
	if (e instanceof arctic.OAuth2RequestError) {
		// Invalid authorization code, credentials, or redirect URI
		const code = e.code;
		// ...
	}
	if (e instanceof arctic.ArcticFetchError) {
		// Failed to call `fetch()`
		const cause = e.cause;
		// ...
	}
	// Parse error
}

Get user profile

Add the users.read and tweet.read scopes and use the /users/me endpoint. You cannot get user emails with the v2 API.

const scopes = ["users.read", "tweet.read"];
const url = twitter.createAuthorizationURL(state, codeVerifier, scopes);

const response = await fetch("https://api.twitter.com/2/users/me", {
	headers: {
		Authorization: `Bearer ${accessToken}`
	}
});
const user = await response.json();

Refresh access tokens

Add the offline.access scope to get refresh tokens.

const scopes = ["offline.access"];
const url = twitter.createAuthorizationURL(state, codeVerifier, scopes);

const tokens = await twitter.validateAuthorizationCode(code, codeVerifier);
const accessToken = tokens.accessToken();
const accessTokenExpiresAt = tokens.accessTokenExpiresAt();
const refreshToken = tokens.refreshToken();

Use refreshAccessToken() to get a new access token using a refresh token. Twitter returns the same values as during the authorization code validation. This method also returns OAuth2Tokens and throws the same errors as validateAuthorizationCode()

import * as arctic from "arctic";

try {
	const tokens = await twitter.refreshAccessToken(refreshToken);
	const accessToken = tokens.accessToken();
	const accessTokenExpiresAt = tokens.accessTokenExpiresAt();
	const refreshToken = tokens.refreshToken();
} catch (e) {
	if (e instanceof arctic.OAuth2RequestError) {
		// Invalid authorization code, credentials, or redirect URI
	}
	if (e instanceof arctic.ArcticFetchError) {
		// Failed to call `fetch()`
	}
	// Parse error
}

Revoke tokens

Use revokeToken() to revoke a token. This can throw the same errors as validateAuthorizationCode().

try {
	await twitter.revokeToken(refreshToken);
} catch (e) {
	if (e instanceof arctic.OAuth2RequestError) {
		// Invalid authorization code, credentials, or redirect URI
	}
	if (e instanceof arctic.ArcticFetchError) {
		// Failed to call `fetch()`
	}
	// Parse error
}
