Learn git

1. Start by creating a Git repository:

• you can do this on GitHub by clicking the + button at the top right
• Select Initialise this repository with a README
• Click Add .gitignore and select your coding environment (Node is good if you use npm)
• Optional: Choose a license
• Copy the URL of the repository

1. cd into a directory such as git

mkdir git && cd $_

• git clone from the git URL

  git clone https://github.com/macintoshhelper/learn-git
  # https://github.com/username/repository-name

  You have now downloaded the git repository You are in the master branch, which should only contain stable, deployable code.

• Create and checkout to a new branch

  # Create and checkout to new branch
  git checkout -b branch-name # where branch-name may be your feature name
  
  # Create new branch
  git branch branch-name
  
  # Checkout to existing branch
  git checkout branch-name

• Write some code and add + commit it

  # Check what files have changed and need to be staged
  git status
  
  # Add a file(s) to be committed
  git add fileName.js fileName2.js <...>
  
  # Commit / create a snapshot of the code that you can revert to
  git commit -m 'Description of the code you are committing'

• Merge with master to update any changes since you wrote the code

  git checkout master
  git pull origin master
  git checkout branch-name
  git merge master

• Push code up to git server

  git push origin branch-name
