🚀 From Code to Release: A DevOps Approach

When I built Sync App, I treated it like a real product — not just a side project. Every release follows a repeatable DevOps pipeline that keeps builds traceable, eliminates the "which file is the right one?" confusion, and gives users a single, reliable download source.

The Release Routine

# 1) Develop and test locally
npm start

# 2) Push code to main
git push origin main

# 3) Tag the version (triggers CI/CD)
git tag v3.0.0
git push origin v3.0.0

# 4) GitHub Actions builds the app
# 5) DMG/ZIP attached to GitHub Release
# 6) Users download from Releases page

What Happens in CI/CD

StepWhat Happens
1. Tag PushGit tag (e.g., v3.0.0) triggers GitHub Actions
2. Clean BuildRuns npm run dist on a fresh macOS runner
3. ArtifactsGenerates DMG and ZIP installers
4. PublishUploads to GitHub Releases automatically

Why This Matters

Repeatable

Every release follows the same process — no manual steps, no surprises.

Traceable

Every binary maps to an exact commit and tag — full audit trail.

Clean Repo

No large binaries in git — artifacts live in GitHub Releases.

Single Source

Users always download from one official location — no confusion.
