Ecma just approved the 1st edition of the new "Source map format" standard, ECMA-426! 🎉 tc39.es/ecma426/2024/

Source maps are already widely implemented, and compatibility was mostly ensured by checking what everybody else was doing. Over the past year, TC39-TG4 has been working hard to ensure alignment between implementations, to align the draft spec with them and to have a shared test suite.

With the solid basis provided by our new spec, we also started working on _new_ source map features to make debugging even more pleasant: stay tuned for what will come next! 😄

This was done with the help of many people, but I want to thanks especially my colleague @asumu.org and friend @jonkuperman.com, with whom we went together through all the process needed to get an actual standard published :)

Please point me to blessed implementation(s) that I can look at to adopt and ensure they're not vulnerable by contributing to them if necessary :)

Good question 😅 Parse/generate/process/remove

There are no blessed implementations, but you might want to take a look at github.com/jridgewell/ 's *mapping packages (that Babel uses), github.com/mozilla/sour..., or github.com/getsentry/ru...
