Problem: When you deploy a new version of your SPA, users with a tab open will keep using the old SPA code. Yesterday, I shared one solution. People suggested dozens of useful variations and alternatives. 🙏 So, here are the best options in the massive thread. 6 ways to tell the SPA a new release is available, simplest options first: 1. Write the version from package.json into index.html as part of the build process. Poll index.html every x minutes and compare the server's index.html to the client's index.html. 2. Create an endpoint on the UI web server that reads the package.json version, and returns it. Poll this every x minutes. This is more efficient than option 1, because the payload is smaller. 3. Use web sockets or server sent events to push a notification to the UI after a deploy instead. This is especially attractive if you’re already using these technologies. 4. Use a service worker to notify the user when the UI is stale. For example, Vite's PWA plugin supports this. 5. Use an API proxy like Cloudfront to fetch the version without involving the backend. More here: rehanvdm.com/blog/using-a-cl… 6. Specify the app version in each HTTP call from the UI via a x-app-version header (or whatever name you like). Validate the x-app-version header on the API server. If x-app-version doesn't match the server's version, notify the UI in the response, either via an HTTP 205, 400, or 422 (the HTTP response you return depends on whether you want calls from a “stale” UI to succeed).

A really cool idea for REPL: The 'explain' command that takes a piece of code and describes its every part in a beginner-friendly way. I don't recall any programming language doing this. Here's my prototype for OCaml 👇 What do you think?

Holy shit. How is this the first time I am reading apenwarr.ca/log/20201227 by @apenwarr? It is the best thing I have ever read on systems architecture, design thinking, and maybe engineering levels too. 🤯🔥 On engineers whose systems thinking skills surpass their coding skills:

Two pet peeves: 1. Developers who don't participate in code reviews 2. Developers who merely approve all pull requests Ignoring or "rubber stamping" pull requests is malpractice. Carefully reviewing PRs and providing thoughtful feedback/questions is part of each dev's job.

Feature Flags are not an excuse for not writing your tests.
