The more I use Git, the more I love it and less I prefer my once trusty SVN.

A while back I read the book Pro Git by Scott Chacon.
The book provides a really good explanation of how Git works and how to use it effectively.
I then found that this book is available online for free and it is now a commonly visited bookmark for me.

Recently my boss sent me a link to a blog post by Scott Chacon that explains the Git workflow that is used at GitHub on a daily basis as we are going to give it a go for our own projects.

In the post, Scott contrasts this to the commonly known ”Git-Flow” and describes how they are both good, but Git-Flow is alot more involved, where the aptly known “GitHub-Flow” is a lot simpler and therefore easier to follow.

For full details, I highly recommend reading the post but basically it involves keeping a master branch that is always stable (and deployable) and using topic branches for development. Once a topic branch is tested locally you open a pull request to have others review it and merge it in to master.

Using pull requests within a single repository for code reviews are really useful!
It allows a discussion thread to take place, commenting on individual lines of code and keeps a history of the rational for any changes.

A good aspect of this approach is that these topic branches can be pushed to GitHub constantly as it will not affect anyone else’s work, and allows the team to have visibility of who is working on what by simply looking at the branch list page.
This of course means that your branches should be descriptively named.

We have been using this workflow for a little while now and have felt compelled to make a small modification.
We have a staging environment which closely matches the production environment and is externally available to show clients new features, etc.
To cater for this we have introduced an additional long-term branch called ”staging”.

This doesn’t affect our existing workflow for the majority of cases, but every now and then we will merge master into staging, then the topic branch into staging to test/preview/etc. (without the need for pull requests/code review). Once the change is tested/previewed in staging and proven to be good, a pull request is opened for the topic branch to be merged into master (as per usual).

One thing to note here is that it’s the topic branch to be merged and not the staging branch. Although in most cases this wont matter, if multiple merges from staging into master occur it can become confusing. Also the merge commit description will contain ”repo/staging” instead of something more descriptive, like ”repo/bundler-upgrade”.

I have really enjoyed using this workflow and it seems to be working quite well so far. In the process of implementing this you really get to see how useful GitHub can be with using pull requests for code reviews and the branch list and network graph features for visualising not only your own progress, but the entire project too.
