This is so interesting! Could you explain to me, as if I were new to all these… let’s say, and considering web hooks as a comparable knowledge gap.. what’s a backhook and how can it be used!!?
- codehammer 4y agoHey! Thanks for the interaction! I'll try to make it simple: A backhook is basically a function that knows from where it has been called. It means that it holds some state bound to a specific context. This has many advantages: - Better typing: Today, most of the context bindings are made by attaching new properties to a request object. That makes typing complicated and not reliable. When using backhooks, your typing is always accurate. - Easier APIs: If you're a library developer, and want to provide a function that relies on headers for a function, you can write it without taking the headers as parameters and instead use other hooks to retrieve it. It simplifies everyone's life. - They are many ways to use backhooks, from retrieving the authenticated user in the current context to aggregate logs with a requestId to make it easy to trace them. I'll be happy to response to any other questions! Thanks for taking the time to comment.
- antipotoad 4y agoReally nice work, thanks! Much cleaner than pulling arbitrary properties off the HTTP request context, and gets a nice conceptual leg-up by analogy to React hooks.
