### Frontend DSNs
Frontend projects need to be created separately in GlitchTip so that browser errors are tracked in their own project (separate from backend errors).
To create frontend projects, use the Django shell command in the [Administration](#server-access) section with `platform="javascript"` and name them `{app}-web` (e.g., `calendar-web`).
Then set `PUBLIC_GLITCHTIP_DSN` in the web app's Docker environment.
## Integration

### Web Apps (SvelteKit) - Future
### Web Apps (SvelteKit)
All 19 SvelteKit web apps have frontend error tracking via `hooks.client.ts`:
```typescript
// src/hooks.client.ts
import { initErrorTracking } from '@manacore/shared-error-tracking';
import { initErrorTracking, handleSvelteError } from '@manacore/shared-error-tracking/browser';
import type { HandleClientError } from '@sveltejs/kit';
initErrorTracking({
serviceName: 'calendar-web',
dsn: import.meta.env.PUBLIC_GLITCHTIP_DSN,
serviceName: 'calendar-web',
dsn: (window as any).__PUBLIC_GLITCHTIP_DSN__,
environment: import.meta.env.MODE,
});
export const handleError: HandleClientError = ({ error }) => {
handleSvelteError(error);
};
```
The DSN is injected at runtime via `hooks.server.ts` (same pattern as auth URL and backend URL):
```typescript
// In hooks.server.ts
const PUBLIC_GLITCHTIP_DSN = process.env.PUBLIC_GLITCHTIP_DSN || '';
// Injected into HTML as window.__PUBLIC_GLITCHTIP_DSN__
```
**What gets captured:**
- Unhandled JavaScript exceptions
- Unhandled promise rejections
- SvelteKit rendering errors (via `handleError` hook)
- Network errors, failed API calls
**Environment variable:**
```env
PUBLIC_GLITCHTIP_DSN=https://<key>@glitchtip.mana.how/<project-id>
```
Browser-specific exports (`@manacore/shared-error-tracking/browser`):
| Function | Purpose |
|----------|---------|
| `initErrorTracking(options)` | Initialize browser Sentry SDK |
| `handleSvelteError(error)` | Capture SvelteKit client errors |
| `captureException(error, context)` | Capture an error manually |
| `captureMessage(message, level)` | Capture a message |
| `setUser({ id, email })` | Set user context |
| `setTag(key, value)` | Set extra context tags |

### Adding a New App
1. Create project in GlitchTip (via UI or Django shell)
**Backend:**
1. Create project in GlitchTip (via UI or Django shell, `platform="node"`)
2. Copy DSN
3. Add `@manacore/shared-error-tracking` to backend package.json
4. Create `src/instrument.ts`
5. Import `./instrument` as first line in `src/main.ts`
6. Set `GLITCHTIP_DSN` env variable
**Frontend (SvelteKit):**
1. Create project in GlitchTip (`platform="javascript"`, name: `{app}-web`)
2. Copy DSN
3. Create `src/hooks.client.ts` (see [Web Apps section](#web-apps-sveltekit))
4. Add `window.__PUBLIC_GLITCHTIP_DSN__` injection in `hooks.server.ts`
5. Add `https://glitchtip.mana.how` to CSP `connect-src` (if CSP is configured)
6. Set `PUBLIC_GLITCHTIP_DSN` env variable in Docker
