What is git?

Git is a distributed version control system which helps developers to collaborate globally.

Why we need such version control system?

Well we need version control system for the following reasons:-

  • It keeps the history of changes developers made.
  • We know who made what changes.
  • It merges conflicting changes (such as two people modified a single file at the same time then it will merge both the changes).

Workflow that makes you project flow smoothly

There are 3 workflows that you can go within Github, namely:-

  • Centralized Workflow

    It is used generally for small teams where everyone works on single branch in a central repository

  • Feature Branch Workflow

    Features developed in dedicated branches and then merged with the main codebase using pull request. Here the main codebase is kept clean and working

  • Forking Workflow

    Each developer forks from the main repo and do changes and send pull requests. Here each developer will have own online repo of the project

Since this a small project right now I will start with centralized workflow.

Enough theory let's do some practical

As hasura provides git integration in their platform I am going to use GitHub as my code repository. So let's initialise our codebase. For instructions about installing git on your computer go to this link. First I have to create a folder and type the command

git init

This will initialise my codebase and track my changes. You will see a hidden folder is created inside my folder snipcode named .git. It contains all the files required for version control.

After adding a readme file to commit the following changes in snip code we have to add and it to the staging area and then commit.

git add README.md
git commit -m "Initial commit"

git commit has an option of adding a message to the commit.

Now all these are happening in my local environment. To push my codebase in GitHub I have to create a repo named snipcode.

After this, I will add the remote in my local repo with name origin(general convention).

git remote add origin https://github.com/sroy8091/snipcode.git

Finally, I will push my local repo to GitHub using push command in the master branch

git push origin master

One of the useful commands is git status. We should always use this to know the status of working tree. One snapshot of my project's status is

And here is the cheat sheet for git provided by the Tower.

Thanks for this! I will refer people to this article when they need to learn the basics of git, instead of my own (messy) notes.

 

Sure. They can directly ask questions to me also. I will try my best.

 

Thanks - will use this as a reference :-)

 

Great article, I like how you broke it down into short sections. Makes it easier to follow. Love the cheatsheet too
