The following file is going to be executed by Husky as post-merge hook.

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

IFS=$'\n'
# regex supports mono-repos with a package.json at root-level and at package-level
PACKAGE_LOCK_REGEX="(^packages\/.*\/package-lock\.json)|(^package-lock\.json)"
# extract all paths to package-lock.json files 
PACKAGES=("$(git diff --name-only HEAD@{1} HEAD | grep -E "$PACKAGE_LOCK_REGEX")")

if [[ ${PACKAGES[@]} ]]; then
  for package in $PACKAGES; do
    echo "📦 $package was changed. Running npm install to update your dependencies..."
    DIR=$(dirname package)
    cd "$DIR" && npm install
  done
fi

The file must be saved as post-merge (no .sh extension) inside the .husky folder. I'm running on macOS with zsh as default shell (see shebang #!/bin/zsh) and it's working. However, I didn't test it with bash, so there might be some changes necessary if you run a different shell.

Note: I'm thinking we should also run this on post-checkout
