# Trunk-Based Development principles:
# 1. Everyone commits to main (or very short-lived branches < 2 days).
# 2. CI runs on every commit — must stay green.
# 3. Use feature flags to hide incomplete features in production.
# 4. Small, incremental commits over large batches.

# Short-lived feature branch (merged same day or next):
git switch main && git pull
git switch -c feat/add-search-bar
# ... small focused changes ...
git add . && git commit -m "feat: add search bar UI component"
git push -u origin feat/add-search-bar
# Open PR -> quick review -> merge -> delete branch

# Feature flag pattern (simple example):
# config/features.js
# module.exports = {
#   newDashboard:  process.env.FF_NEW_DASHBOARD  === 'true',
#   betaCheckout:  process.env.FF_BETA_CHECKOUT  === 'true',
# };

# Usage in code:
# const flags = require('./config/features');
# if (flags.newDashboard) {
#   return res.render('dashboard-v2');
# }
# return res.render('dashboard');

# When the feature is complete and rolled out:
# 1. Remove the feature flag check
# 2. Delete the flag from config
# 3. Clean up old code path
