patch-jest-cache v1.11.0

patch-jest-cache

patches jest caching to work around an issue outstanding since 2017 cache write race condition across processes

• make caching opportunistic: if it works, great, if it fails, c'est la vie!
  • caching should be to improve performance, not a lynchpin
• facilitate complete disable of read and/or write cache

  • because jest writes out cache files even when invoked with --no-cache, wasting time on I/O for files that won't be used

usage

npx patch-jest-cache {options}

• default behavior patches cache reading and writing to only warn on error
• specify --no-warn-on-errors to suppress warning messages
• specify --disable-read-cache or --disable-write-cache to completely disable cache read / write

reverting

either run npx patch-jest-cache --revert or re-install your node_modules, eg with npm ci
