(Rust playground maintainer here) Incidentally, I also updated the Rust playground today. My usual process is to update everything [0] that is SemVer compatible and then one-by-one update packages with SemVer incompatible version bumps. During the upgrade, I was thinking to myself how generally I’m fairly blasé about these updates — I don’t even attempt to build the code with the SemVer compatible updates because it’s so rare for a crate maintainer to stuff up such an update. The SemVer incompatible updates get a build just as a sanity check. Contrast this to the JS dependencies where an upgrade tends to instill more dread in me. Part of this is a lack of confidence in my test suite, part of it is that it’s the more UI heavy component which is hard to write tests for in the first place, but a non-zero part is my lack of trust in the JS libraries and tooling. I wonder how much of that is still true today versus how much I am once bitten, twice shy.
