Getting started

Prerequisites

• Rust (stable)
• Node.js 22+
• pnpm (version from packageManager in package.json)
• Tauri prerequisites for Windows

Development

git clone https://github.com/KetusDev/Vanta.git
cd Vanta
pnpm install
pnpm tauri dev

Local production build

pnpm tauri build

Installers are written to src-tauri/target/release/bundle/.

CI & releases

Two separate GitHub Actions workflows:

CI (ci.yml) — runs on every push / PR to main

Trigger	Action
Push to main	✅ Runs
Pull request to main	✅ Runs
Push tag v*	❌ Does not run (Release workflow handles tags)
Other branches	❌ Does not run

What it does: pnpm build + cargo check on Windows (~5 min).
What it does not do: build installers or publish a GitHub Release.

Release (release.yml) — runs only on version tags

Trigger	Action
git push origin v1.0.0	✅ Runs
Regular commit on main	❌ Does not run

What it does: full Tauri build and uploads .msi / .exe to a new GitHub Release.

The tag must match the app version in src-tauri/tauri.conf.json (e.g. version 1.0.0 → tag v1.0.0):

git tag v1.0.0
git push origin v1.0.0

Monitor progress under Actions → Release, then check Releases for download links.
