I work on Jest at FB.

* I agree regexes suck but that's all we had five years ago when it was started. Would love to move to a glob system incrementally but most of that will have to come from the community. I'm also still concerned about performance. We match things against tens of thousands of files a lot and regex seems strictly faster to me but I'm happy to be proven wrong or shown that it won't be relevant. * There is one minor issue with create-react-app's recommended use of node_modules to split up things. I would recommend lerna for multi-package development ( https://github.com/lerna/lerna ) and we are hoping to put whatever fix in place here that will work well. There are workarounds but they aren't great.




node-glob was released in 2010


Thanks! That's great. Maybe you can help us upgrade then? Jest is fun to contribute to.
