Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[AskJS] Any good shortcuts for migrating off of enzyme?
If jscodeshift is confusing, I recommend looking into using recast directly, along with ast-types for AST traversal and its node factories. Inside your visitors, write some conditionals that check for the patterns you want to detect, then mutate the node passed to the visitor, or otherwise mutate the AST. Keep going until tests are passing.

Evan you on Svelte migration from Vue
I ended up writing my own codemod tool based on recast to automate most of the repetitive, mindless grunt work. Even with the tool shaving hundreds of hours off of the migration effort, there's still a huge amount of work left, since we need to find or create Vue 3-compatible alternatives of all of our Vue 2-only dependencies. Some of these dependencies (e.g. vee-validate) are used pretty ubiquitously too

Which library to use for AST manipulation?
I had great results with a combination of babel + recast. Babel is doing the job and Recast is mostly here to preserve the original style when printing code again. I animated a workshop @ Node.JS Montréal 2019 that was recorded here. We cover the parse/transform/print of code using Babel (live coding starts around 45').

Show HN: Monocle – bidirectional code generation library
This is neat! I’m curious if you see this being extended for other languages, or the concept being applied in other projects?
As for similar concepts, several projects by builder.io have some overlap. Most notably Mitosis[1], but I’d be shocked if TS-Lite[2] isn’t using similar techniques. Potentially Qwik[3] as well but I’m not sure, I would have bet that’s using Mitosis but it looks like that’s the other way around.
