`bash

`Create feature branch`


git checkout -b feature/new-feature main
Make changes and commit
git add .
git commit -m "feat: add new feature"
Push changes
git push origin feature/new-feature
Create pull request
Review and merge

`$1`

branch_naming:

features: feature/*

bugfix: fix/*

hotfix: hotfix/*

release: release/*

commit_conventions:

- feat: new features

- fix: bug fixes

- docs: documentation

- style: formatting

- refactor: code restructuring

- test: adding tests

- chore: maintenance

`$1`

`bash

`Initialize Gitflow`


git flow init
Start feature
git flow feature start new-feature
Finish feature
git flow feature finish new-feature
Create release
git flow release start 1.0.0
git flow release finish 1.0.0

master = main

develop = develop

[gitflow "prefix"]

feature = feature/

release = release/

hotfix = hotfix/

support = support/

versiontag = v

`$1`

`bash

`Work directly on main`


git checkout main
git pull origin main
Create short-lived feature branch if needed
git checkout -b feature/quick-fix
Make changes
git checkout main
git merge feature/quick-fix

`$1`

`javascript

const features = {

newFeature: {

enabled: process.env.ENABLE_NEW_FEATURE === 'true',

rolloutPercentage: 25

}

function isFeatureEnabled(feature, userId) {

return features[feature].enabled &&

(hash(userId) % 100) < features[feature].rolloutPercentage;
