Git hooks
In root of project:
mkdir -p hooks
cd hooks
touch post-merge
post-merge:
#! /bin/bash
# all stdio in this script after this line will be sent to the log file
# note that we're appending so that the log file is not overwritten every time this script is called
exec >> log/hooks-out.log 2>&1
if git diff-tree --name-only --no-commit-id ORIG_HEAD HEAD | grep --quiet 'package.json'; then
echo "$(date): Running npm install because package.json changed"
# redirecting stdout to dev/null trashes quiets the stdout, but it's stderr will go to our log file
npm install > /dev/null
else
echo "$(date): No changes in package.json found"
fi
Give premission:
chmod +x hooks/post-merge
Link to .git:
ln -fv hooks/post-merge .git/hooks/
Later if co-worker upgrade some packages, when we pull the changes, it will trigger `npm install
