cd your-project-folder
npx degit https://github.com/hexagon6/tcr-node.git#main .
> cloned hexagon6/tcr-node#main

working with git branches

initial preparation

0. preparee a new git repo git init

1. b) don't forget to configure your name and email if you haven't done it before or globally

git config user.email "me@example.com"
git config user.nae "Me Example"

0. do your first commit to start the project git commit -am "init project"

workflow

1. change to your feature-branch git checkout -b feature-branch

2. do your work in TCR fashion:

• every time you save a file with .mjs extension, tests are run
• A) if no error happened, then all your files are committed with a "working" message
• B) if an error happened, then all your state is reset to the commit before

3. once your feature is complete you can give it custom git commit messages or squash it if you want a meaningful git history.

4. push to your remote and do a Merge Request (gitlab) or Pull Request (github)

customization

If you want to run a different command on save, change the match rule (regex) or cmd (string) in .vscode/settings.json under key "emeraldwalk.runonsave".
