Jest builds unable to exit
Closed this issue · 6 comments
citation-js requires sync-request which in turn uses sync-rpc. Simply importing the citation-js package causes my CI build to fail as Jest doesn't exit and throws the following warning:
This happens when running jest 24.5.0 on node 10.14.1. I've submitted an issue on sync-rcp here - but am unsure where in the stack this open handler needs to be addressed.
Any suggestions for working around this?
Thanks!
I'd really like to drop the sync-request dependency for a number of reasons, although I hadn't discovered this one yet. I developed sync-fetch for this (which doesn't use a separate process for the server), however I don't want to replace it and introduce regressions without a new major version. Additionally, I'd have to drop Node 6 support probably.
Thanks for the context. Any hope of a @x.0.0-beta in the interim?
Node 6 appears to be out of "maintenance" on the nodejs release chart since May 2019 - so a major version update that loses support for Node 6 doesn't seem like an egregious decision from my (biased) perspective 🙂
Can you try citation-js@0.5.0-alpha.0?
Coming from successful tests with citation-js@0.4.10 and running tests with citation-js@0.5.0-alpha.0 I get a new error in a path that seems unrelated to sync-fetch:

Seems to come from this recent line change: citation-js/citation-js@08da3e7#diff-040f2ba621ded4a0338c7ba7939eeed6R191
I've just released 0.5.0-alpha.2 with a fix. Sorry for the peer dependency warnings, I'll fix that next release.
That did the trick! Smooth sailing on my end now.
Thanks so much!
