wtf is twitter-avatar-url?

twitter-avatar-url is a small JavaScript helper that does exactly what its name suggests: you give it a Twitter username (or a list of them), and it gives you back the URL for that user's profile picture. It returns both a small and a large version of the image, so you can pick whichever size fits your needs. Under the hood, the package talks to Twitter's official API to look up user accounts and fetch their avatar image links. You need to set up a Twitter developer account and get an API token to use it, since it relies on Twitter's backend to retrieve the data. The tool handles some of the tedious parts for you, if you pass in duplicate usernames, it cleans them up automatically, and if you send more usernames than Twitter allows in a single request, it splits them into batches and stitches the results back together so you don't have to manage that yourself. Someone building an app or website that displays Twitter profiles, say, a blog that shows author photos, a directory of conference speakers with their social links, or a dashboard that lists customer Twitter handles, would find this useful. Instead of manually looking up and saving each avatar image, you could fetch them programmatically and always have the current profile picture, even if a user updates it. One important caveat: this package is retired. Twitter shut down the free version of its API in February 2023, which broke the underlying mechanism this tool depends on. The code is still available to read and learn from, but it won't work as-is without a paid Twitter API plan. It's essentially a snapshot of a simpler era when Twitter's API was freely accessible to small projects.
