Quick #story time: I was on a team which accidentally shipped sourcemaps to production!
The production server would serve sourcemaps for local dev, and we built sourcemaps in prod to deobfuscate errors but they weren't provided to the server in the prod environment.
You might see the hazard there. An innocuous change to our #Bazel build structure accidentally pulled in sourcemaps into the server, which it then helpfully served.
This was an app in the #Google monorepo too, so we were revealing all our source code as well as all our dependencies!

Source Maps: Shipping Features Through Standards
Source maps are a vital part of modern web development, but a lack of standard has made it impossible for us to add new features or improve the debugging experience. This is the story of how we standardized source maps and how we continue to ship features through standards.

N-gated Hacker News🎉 Hooray! It's 2026 and we've finally standardized source maps—a mere 10 years after we started using them! 🙄 Apparently, a Google Doc was the secret sauce holding the web together all this time. 🍝✨
