Git: Setup
1. Install git (Depends on your OS)
yay -S git # arch
apt install git # ubuntu/debian
choco install git # windows
2. Setup keys
ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_muni -C "xuser@fi.muni.cz"
3. Add public key to Gitlab
9
Git: Basics
Commit in Conventional commits
git config --global core.excludesFile "**/node_modules"
git config --global user.name xuser
git config --global user.email xuser@fi.muni.cz
git clone <url> # Clones the repository
git status # Show status of added, removed files
git branch feature/ite-01 # Create new branch
git commit -am "feat: added erd" # Commit all tracked files
git push origin feature/ite-01 # Push commited to remote branch
Cheatsheet
10
Git: Gitflow
Starts from master
Feature branches contain new features,
additions
Master/Main is stable (tagged)
Note: You'll most likely work in trunk based
development (it ignores the develop branch)
In-depth explanation
11
Git: Merge requests / Pull
request
MR/PR the way you check source code
changes into a main branch
Before pushing code, check common mistakes
CI is your enemy
We require you to discuss changes
12
Workspace setup
IDE: Webstorm, VSCode, vim

Git: Gitkraken, Github desktop*
Extensions: PlantUML, GraphViz
Extensions will be announced in every seminar session (We use many in this course)

*Note: ignore if you like solving conficts on your own

Activity
1. Make group of 3-4 students
2. Model: Spotify domain on paper
Artists, Albums, Songs, Playlists, Genres,
Users
3. Logical model: focus on attributes, relations
4. Compare within groups in seminar
5. Code PlantUML (save it locally)
6. Git-Push to Gitlab (next slide)
14
Publishing the Spotify diagram as Iteration 00
1. Fork the repository pb138/pb138-iterations-2022
2. Clone the repository
3. Create the branch feat/iteration-00
4. Save spotify.puml to branch feat/iteration-00
5. Invite your seminar tutor(s) to the project as developer(s)
6. Open merge request from feat/iteration-00 to main
7. Assign tutor as Assignee and Reviewer on Merge request
15
Publishing the Spotify diagram as Iteration 00
And now wait... For the code review.
