Why Sync App?
Built for users who want simple, dependable backups without enterprise complexity — and without the slowdowns of Finder copies.
- Faster than Finder for large or repeated syncs
- Incremental by default — only copies what changed
- Profiles — save and reuse source/destination pairs
- Scheduling — automated daily or weekly syncs
- Notifications — macOS alerts on success or failure
- History & Logs — timestamps, durations, and per-file details
- Preview mode — validate before writing any files

🚀 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 v2.0.0 git push origin v2.0.0 # 4) GitHub Actions builds the app # 5) DMG/ZIP attached to GitHub Release # 6) Users download from Releases page
What Happens in CI/CD
| Step | What Happens |
|---|---|
| 1. Tag Push | Git tag (e.g., v2.0.0) triggers GitHub Actions |
| 2. Clean Build | Runs npm run dist on a fresh macOS runner |
| 3. Artifacts | Generates DMG and ZIP installers |
| 4. Publish | Uploads 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.
