# Deployment
Production frontend deploy is handled by Gitea Actions in `.gitea/workflows/deploy.yml`.
## Trigger
A push to `main` triggers the deploy workflow.
```yaml
on:
push:
branches:
- main
```
## CI/deploy steps
1. Checkout code.
2. Set up Node.js 22 with `actions/setup-node`.
3. Install dependencies with `npm ci`.
4. Type check with `npx tsc --noEmit`.
5. Check formatting with `npm run format:check`.
6. Run tests with `npm test`.
7. Build with `npm run build` using:
```bash
VITE_API_URL=https://api.ark-library.com
VITE_DISABLE_ADMIN=true
```
8. Configure SSH key from `DEPLOY_KEY` secret.
9. `rsync --delete` built `dist/` to both frontend servers:
```text
ec2-user@FRONTEND_1_HOST:/var/www/ark-library/
ec2-user@FRONTEND_2_HOST:/var/www/ark-library/
```
10. Verify both servers have matching `index.html` SHA-256 checksums.
11. Remove temporary SSH key.
## Required repository secrets
The workflow expects these Gitea secrets:
- `DEPLOY_KEY`
- `FRONTEND_1_HOST`
- `FRONTEND_2_HOST`
## Common failures
### Node version is too old
The workflow pins Node.js 22 using `actions/setup-node`. This keeps the self-hosted runner from using an older system Node version during `npm ci`, tests, and build.
If `actions/setup-node` cannot run on the self-hosted runner, upgrade the runner host's Node.js installation to Node 22 or at least Node 20.19 before restarting the runner service.
### TypeScript fails on unused imports
This repo uses `noUnusedLocals` and `noUnusedParameters`. Remove unused imports/variables and rerun:
```bash
npx tsc --noEmit
```
### Format check fails
Run:
```bash
npm run format
npm run format:check
```
Then commit the formatting changes.
### Build uses wrong API
Check `VITE_API_URL` in `.gitea/workflows/deploy.yml` or local `.env`.
### One frontend server differs from the other
The workflow compares remote `index.html` checksums. If it fails, inspect the rsync step and both `FRONTEND_*_HOST` values.
