twitter-api-v2-user-oauth2-example

This project shows you how to make a simple 3-legged OAuth2 user flow (BETA).

Requirements

Packages

Install all packages of project, configure .env with required properties, then start TypeScript compiler.

npm i
cp .example.env .env
# ...configure .env with consumer keys
# then start the server
npm run start

Twitter app config

• Copy .example.env to .env file
• Add your consumer key + consumer secret to .env file
• Ensure http://localhost:5000/callback is present in allowed callback URLs, inside your Twitter application settings (in developer portal).

Testing the app

Navigate to http://localhost:5000 to test callback-based flow.

How it works

Callback flow

1) It generate a authentification link (routes/callback.ts, router.get('/')) that renders into views/index.ejs. 2) User clicks link, and is redirected to routes/callback.ts, router.get('/callback') route. 3) Route use stored tokens into session to generate definitive access token, then renders views/callback.ejs with access token data.
