      Continuing the trend of nice error messages. Validation of package.json including parsing of semver ranges/versions with frames pointing to the exact source location in JSON. A combination of a custom JSON parser, and then chaining it with a custom semver parser with an offset. pic.twitter.com/dQC3U5JEI9

      Screen recording of running Rome in daemon mode and linting a project. Same as yesterday, 524 files, 40,000 lines of code. Difference here is that subsequent commands pull from a memory cache. Watch the last command closely, it's instantaneous. pic.twitter.com/33dUDS07Ew

      The Rome testing framework will give you a stack trace when a test worker becomes unresponsive due to an infinite loop in a test. Works by using the V8 inspector protocol to trigger the debugger and dump the paused call frames. pic.twitter.com/h3I3aBESG1

          Following up from my earlier tweets about JS parsing. I've made the Rome JS parser tolerant. Parsing will not be stopped on syntax errors. Uses the same diagnostic format as everything else, so they can be as rich as possible. pic.twitter.com/nires2YzJF

          When Rome is bundling and it finds an unknown import, it will tell you the exact spot that's unknown. In the screenshot shown, there is indirection happening in a package.json. Rome tells you that the problem is actually in the package.json main field, rather than your import. pic.twitter.com/ij2VwVq9xD

          Rome diagnostics are so good. One thing I particular that I love doing is tagging test cases with additional diagnostic information, so that when they fail you have context supplied by the test.

          Added a --visualize-markers flag to Rome that will output a timeline view in the console with captured performance markers. pic.twitter.com/nCTOU0m3BX

          Rome now has first class support for URLs alongside file paths. This allows you to use a URL anywhere a file path could be used, and it will be downloaded and cached. You may be familiar with this behaviour from deno and regular browsers. pic.twitter.com/OUO8NksAln

          Now that this tweet is buried. Just wanted to note that Rome is not vaporware. If I had my way it would already be open source but I technically I do not "own" the code 🤷‍♀️
