Node.js

npm install --save-dev lefthook

yarn add --dev lefthook

pnpm add -D lefthook

Note: If you use pnpm package manager make sure to update pnpm-workspace.yamls onlyBuiltDependencies with lefthook and add lefthook to pnpm.onlyBuiltDependencies in your root package.json, otherwise the postinstall script of the lefthook package won’t be executed and hooks won’t be installed.

Note: lefthook has three NPM packages with different ways to deliver the executables

1. lefthook installs one executable for your system

   npm install --save-dev lefthook
   

2. legacy^[1] @evilmartians/lefthook installs executables for all OS

   npm install --save-dev @evilmartians/lefthook
   

3. legacy^[1:1] @evilmartians/lefthook-installer fetches the right executable on installation

   npm install --save-dev @evilmartians/lefthook-installer
