Best Practices

General Rules

  1. Version Control Sensitive Data: Never commit:
  2. API keys, passwords, tokens
  3. Private keys, certificates
  4. Database credentials

  5. Environment variables with secrets

  6. Exclude Build Artifacts:

  7. Compiled code
  8. Distribution packages

  9. Dependency directories

  10. Ignore IDE Files:

  11. Personal workspace settings

  12. Project-specific IDE configurations

  13. Keep It Updated:

  14. Review and update .gitignore regularly
  15. Add new patterns as project evolves

Using .gitignore

## Check if a file would be ignored
git check-ignore -v path/to/file

## Remove already tracked files from git
git rm --cached <file>
git rm -r --cached <directory>

## Force add an ignored file (use carefully)
git add -f <file>

Global .gitignore

## Set global .gitignore for all repositories
git config --global core.excludesfile ~/.gitignore_global

## Create global .gitignore
cat > ~/.gitignore_global <<EOF
.DS_Store
.vscode/
.idea/
*.swp
EOF
