1k Patch Package Workflow

patch-package workflow

Patches live in patches/<pkg>+<version>.patch and auto-apply on install. Never hand-edit a .patch — edit the node_modules/ source, then generate.

Generate

1. Edit node_modules/<pkg>/.... Comment lines out (don't delete) with a // OneKey patch: <why> note above.
2. Generate — must drop resolutions first or it fails with Couldn't find any versions for ...:

cp package.json /tmp/pkg.bak
node -e "const fs=require('fs');const p=require('./package.json');delete p.resolutions;fs.writeFileSync('package.json',JSON.stringify(p,null,2)+'\n')"
npx patch-package <pkg>          # npx, not yarn
cp /tmp/pkg.bak package.json     # restore byte-exact

Fallback (generate still fails: offline / private dep)

Diff the edited file against the pristine tarball in the Yarn cache:

EXTRACT=$(mktemp -d); unzip -q .yarn/cache/<pkg>-npm-<ver>-*.zip -d "$EXTRACT"
PRISTINE=$(find "$EXTRACT" -path "*<rel/path/File.ext>"); SUB="node_modules/<pkg>/<rel/path/File.ext>"
REPO=$(mktemp -d); (cd "$REPO" && git init -q && mkdir -p "$(dirname "$SUB")" \
  && cp "$PRISTINE" "$SUB" && git add -A && git -c user.email=x -c user.name=x commit -qm base \
  && cp "$OLDPWD/$SUB" "$SUB" && git diff) > patches/<pkg>+<version>.patch

Verify (required)

git apply --check -p1 patches/<pkg>+<version>.patch   # must pass against a pristine file
grep -c android/build patches/<pkg>+<version>.patch   # must be 0 (else rm -rf node_modules/<pkg>/android/build, regenerate)
