patcheer

Super naive patcher. One command to copy a package folder from node_modules to ./patches. Patch the package. Another command to destructively copy all the patches in ./patches to node_modules.

Getting started

Let's use lodash as an example.

• npm i -D patcheer
• npm i lodash axios
• npx patcheer copy lodash
• Tweak anything in ./patches/lodash
• npx patcheer copy axios
• Tweak anything in ./patches/axios
• npx patcheer apply

Postinstall

To have it automatically apply patches after you run npm install on a project, just add this to your package.json scripts.

"postinstall": "npx patcheer apply"

If you're trying to build with Yarn or Bun, you'll need to add postinstall-postinstall to your dev dependencies.
