What is git? A distributed version-control system for tracking changes in source code during software development. @waterproofheart 🔗 www.aboutmonica.com/

What is the relationship between GitHub/BitBucket/GitLab and git?? @waterproofheart 🔗 www.aboutmonica.com/

TIME TRAVEL IN GIT It’s not a bug! It’s a feature. @waterproofheart 🔗 www.aboutmonica.com/

DEBUGGING The marketing mix is a business tool used in marketing and by marketers, originally can be used @waterproofheart 🔗 www.aboutmonica.com/

CREATE FUTURE COMMIT Checkout new branch Change computer time & replicate issue locally Squash bug and fix issue Commit and push fix Oops! @waterproofheart 🔗 www.aboutmonica.com/

Is that the only way to commit in the future? @waterproofheart 🔗 www.aboutmonica.com/

OTHER WAYS TO MODIFY COMMIT DATES

The Date format must follow the Git standard RFC 2822 or ISO 8601. - Can rebase and apply changes commits to the past as well. @waterproofheart 🔗 www.aboutmonica.com/

What does this look like on GitHub? Write here a list of features, textboxes easy to edit Here you can write more More about your project. Statistics, analysis and content export GIT_AUTHOR_DATE=”Wed Mar 20 15:12:30 2019 -0700” export GIT_COMMITTER_DATE=”Wed Mar 20 15:12:30 2019 -0700” git commit -m “future commit” @waterproofheart 🔗 www.aboutmonica.com/

What is a git hook? Bash scripts that are executed at specific points within the git workflow. precommit, postcommit, prepush, postpush, etc…. Git Hooks Documentation: https://git-scm.com/docs/githooks @waterproofheart 🔗 www.aboutmonica.com/

Where do they live? Every Git repository has a hidden .git/hooks directory with a script for each hook you can bind to. These can be modified. @waterproofheart 🔗 www.aboutmonica.com/

How can git hooks be used? ● Warn when committing to master ● Run linting and tests before committing ● Warn or abort when committing code with: console.logs(), sensitive credentials, merge conflict strings or large files. ● Send notifications after a commit is pushed ● Sending intl objects to be translated ● And 1270824+ other ways. @waterproofheart 🔗 www.aboutmonica.com/

Limitations of Git Hooks ● Limited enforcement - can easily be overridden —no-verify or forced pushes ● Local hooks != shared hooks as .git/hooks not in version control ● Doesn’t replace CI, server-side branch protection or code reviews @waterproofheart 🔗 www.aboutmonica.com/
