## Stack
|
|
|
|
**Backend:** Bun runtime, Hono web framework, Drizzle ORM, PostgreSQL 17, Zod validation, Handlebars templates, nodemailer
|
|
|
|
**Frontend:** Next.js 16 App Router (Turbopack), shadcn/ui (Tailwind CSS), next-themes, date-fns, lucide-react icons
|
|
|
|
**Fonts:** Inter (variable), JetBrains Mono
|
|
|
|
## Running Locally
|
|
|
|
### Prerequisites
|
|
- Bun (`nix-shell -p bun` or install globally)
|
|
- Node.js 22+ (`nix-shell -p nodejs_22`)
|
|
- Docker (for PostgreSQL)
|
|
- PostgreSQL container: `docker run -d --name tessera-db -e POSTGRES_USER=tessera -e POSTGRES_PASSWORD=*** -e POSTGRES_DB=tessera -p 127.0.0.1:5433:5432 postgres:17-alpine`
|
|
|
|
### Start backend
|
|
```bash
|
|
cd ~/projects/tessera
|
|
cp .env.example .env
|
|
npm run dev:backend # Starts API on port 9876
|
|
```
|
|
|
|
### Run migrations
|
|
```bash
|
|
npm run db:migrate
|
|
npm run db:seed # Demo data
|
|
npm run db:seed:reset # Reset + re-seed
|
|
```
|
|
|
|
### Start frontend
|
|
```bash
|
|
cd web
|
|
npm install # Use npm, NOT bun
|
|
bun run dev # Dev server on 127.0.0.1:3100 (HMR)
|
|
```
|
|
|
|
## API Endpoints
|
|
|
|
All endpoints on port 9876. Frontend proxies `/api/*` via `next.config.ts`.
|
|
|
|
| Method | Path | Description |
|
|
|--------|------|-------------|
|
|
| GET | /health | Health check |
|
|
| GET | /tickets | List tickets (?queue_id=&status=&owner_id=&team_id=&q=&limit=&cf.*=) |
|
|
| POST | /tickets | Create ticket |
|
|
| GET | /tickets/:id | Get ticket with custom fields |
|
|
| PATCH | /tickets/:id | Update ticket (validates lifecycle, runs scrips, returns scrip_results) |
|
|
| POST | /tickets/:id/preview | Dry-run scrips for status change |
|
|
| POST | /tickets/:id/comment | Add comment to ticket |
|
|
| GET | /tickets/:id/transactions | List ticket transactions |
|
|
| GET/POST/PATCH | /queues | CRUD queues |
|
|
| GET/POST/PATCH/DELETE | /scrips | CRUD scrips |
|
|
| GET/POST/PATCH | /custom-fields | CRUD custom fields |
|
|
| GET/POST/PATCH | /lifecycles | CRUD lifecycles |
|
|
| GET/POST/PATCH/DELETE | /users | CRUD users |
|
|
| GET/POST/PATCH/DELETE | /templates | CRUD templates + POST /preview |
|
|
| GET/POST/PATCH/DELETE | /views | CRUD saved views |
|
|
| GET/POST/PATCH/DELETE | /teams | CRUD teams + POST/DELETE members |
|
|
| GET/POST/PATCH/DELETE | /dashboards | CRUD dashboards + widgets + widget data |
|
|
|
|
## Key Design Decisions
|
|
|
|
- **Ticket IDs are sequential integers** (1, 2, 3...), formatted as `TKT-0001` for display. No UUIDs.
|
|
- **Transaction-centric:** Every state change creates a transaction record. The scrip engine runs on transactions.
|
|
- **Two-phase scrip engine:** Prepare (no side effects) then Commit (execute actions). Supports dry-run mode.
|
|
- **Lifecycle state machines:** Per-queue configurable status transitions with wildcard support.
|
|
- **SQL-level filtering:** Ticket filters (status, queue, owner, team, custom fields) pushed to PostgreSQL via Drizzle WHERE clauses.
|
|
- **No ORM for frontend:** Drizzle is only on the backend. Frontend uses a typed fetch wrapper (`web/src/lib/api.ts`).
|
|
- **Dev server over production:** Use `bun run dev` (port 3100) with HMR. Build+restart only when dev server has issues.
|
|
- **Design consistency:** See `docs/design-system.md` for the design rules applied across the app.
|
|
|
|
## Git Workflow
|
|
|
|
Repo: `https://git.gjermund.xyz/gjermund/tessera`
|
|
|
|
```bash
|
|
git remote set-url origin https://gjermund:TOKEN@git.gjermund.xyz/gjermund/tessera.git
|
|
```
|
|
|
|
## Common Issues
|
|
|
|
- **Frontend shows skeleton/blank page:** Dev server may have HMR issues. Kill port 3100, rebuild with `npm run build`, restart with `npm run start`.
|
|
- **Backend not running on 9876:** Restart with `bun run src/index.ts`. Check port with `ss -tlnp | grep 9876`.
|
|
- **Database connection refused:** Docker container may be stopped. `docker start tessera-db`.
|
|
- **Build errors after migration:** Run `bun run src/db/migrate.ts` to apply new migrations.
