Make jest small
See original GitHub issue🚀 Feature Proposal
Make jest small again (less than 30 MB)
Motivation
It appears jest is the largest when comparing other test harnesses.
jest@0.1.40 was small…it looks like jest@12.1.0 is when the size exploded.
Now jest@23.0.0 is even larger.
Example
| package | install size |
|---|---|
| tap@12.0.1 | |
| ava@0.25.0 | |
| mocha@5.2.0 | |
| tape@4.9.0 | |
| jasmine@3.1.0 | |
| jest@0.1.40 | |
| jest@12.1.0 | |
| jest@23.0.0 | |
| jest@23.0.1 |
Click a badge above to see a history of the install size.
Pitch
Every repo needs to install jest to run it’s own tests.
One repo with 50 MB is maybe not too bad but your app is split into 200 microservices, that’s 10 GB of jest!
