1. GIT HOOKS
Error prevention via automation with Git
By André Figueira

2. THE HOOKS: CLIENT
 Git hooks are scripts which get fired at certain events, e.g. push, commit, etc…
 Different types of hooks, client & server
 Client e.g.
 Pre-commit
 Additional checks…
 Post-commit
 Notifications…
 Post-checkout
 Modifications to environment…
 Et Cetera…

3. THE HOOKS: SERVER
 The cool stuff!
 Can be simple or complex…
 Types:
 Pre-receive
 Check to see what is being done and prevent it if needed, e.g. deletion of a file
 Post-receive
 Runs after the push process has finished
 Can be used for deployment
 Simple checkout, rsync, etc…
 The sky is the limit…

4. BENEFITS OF USING HOOKS
 Hooks can greatly increase our productivity
 How?
 Less time spent running additional diffs, checking to see if files are synced between FTP and Git
 Single point of contact from inception to deployment without the middleman that is FTP
 BLAME! AKA, visibility of all deployment to production, know every move anyone makes to
production code
 Less mistakes, automation in deployment means we are reducing the factor of human error
 Easier to do continuous integration
 Run anything off the back of deployment e.g.
 Notify all developers by email
 Automatically download dependencies on server which are not stored in Git, e.g. via composer
 So much more!
