A release-readiness QA pass over the whole product. The commits split into defects a user would hit and gates that were reporting green while measuring nothing. ## Fixes that change behaviour Rate limiting was bypassable on every install: TRUST_PROXY defaulted to true, so request.ip came from a client-set header and a forged X-Forwarded-For got past the login limiter. The default is now a private-network trust list. A transient Postgres outage stranded in-flight jobs, leaving finished output on disk with no row pointing at it. A reconciler now resolves those rows and adopts the bytes rather than dropping the work. A Redis connection that moved to a new address wedged every read-blocked consumer, so completions stopped signalling while health still answered 200. Socket timeouts plus subscriber pings recover it. Installing more than one AI bundle left the shared venv multi-versioned and silently broke three tools. The installer now reconciles distributions to one version each. Converting an image to JXL at quality 1 through 4 returned a 500, because libjxl 0.7 rejects the distance those values compute. The quality is floored at what the encoder honours. A missing ffmpeg was also reported to the user as a corrupt upload; it now says the engine is unavailable. RAW uploads reached an unpatched LibRaw on arm64, so it is built from source at 0.22.2, and the release scan was split so it can fail on an unfixed critical instead of hiding it behind ignore-unfixed. ## Gates that could not fail Two mutation lanes ran zero mutants because Stryker crawled the gitignored docs build; coverage discarded its whole report on any failing test; the lint gate skipped root tests, scripts, and two workspaces; and several generated matrices counted a host missing ffmpeg as a passing tool. Each now measures what it claims. Full evidence and the outstanding release items are tracked locally and are not part of this branch.

# Utvecklarguide {#developer-guide}
|
|
|
|
Så ställer du in en lokal utvecklingsmiljö och bidrar med kod till SnapOtter.
|
|
|
|
## Förutsättningar {#prerequisites}
|
|
|
|
- [Node.js](https://nodejs.org/) 22.22+
|
|
- [pnpm](https://pnpm.io/) 9+ (`corepack enable && corepack prepare pnpm@latest --activate`)
|
|
- [Docker](https://www.docker.com/) (krävs för lokal Postgres + Redis, containerbyggen och AI-funktioner)
|
|
- Git
|
|
|
|
Python 3.11+ behövs bara om du arbetar med AI/ML-sidovagnen (bakgrundsborttagning, uppskalning, OCR).
|
|
|
|
## Konfiguration {#setup}
|
|
|
|
```bash
|
|
git clone https://github.com/snapotter-hq/snapotter.git
|
|
cd snapotter
|
|
docker compose -f docker-compose.dev.yml up -d # start Postgres + Redis
|
|
pnpm install
|
|
pnpm dev
|
|
```
|
|
|
|
Detta startar två utvecklingsservrar:
|
|
|
|
| Tjänst | URL | Anmärkningar |
|
|
|----------|--------------------------|------------------------------------|
|
|
| Frontend | http://localhost:1351 | Vite-utvecklingsserver, proxar /api |
|
|
| Backend | http://localhost:13490 | Fastify API (nås via proxy) |
|
|
|
|
Öppna http://localhost:1351 i din webbläsare. Logga in med `admin` / `admin`. Du kommer att uppmanas att byta lösenord vid första inloggningen.
|

|
```bash
|
|
pnpm dev # start frontend + backend
|
|
pnpm build # build all workspaces
|
|
pnpm typecheck # TypeScript check across monorepo
|
|
pnpm lint # Biome lint + format check
|
|
pnpm lint:fix # auto-fix lint + format
|
|
pnpm test # unit + integration tests

|
|
pnpm test:e2e # Playwright e2e tests
|
|
pnpm test:coverage # tests with coverage report
|
|
```
|
|
|
|
## Kodkonventioner {#code-conventions}
|
|
|
|
- Dubbla citattecken, semikolon, 2 blanksteg indrag (enforced av Biome)
|
|
- ES-moduler i alla arbetsytor
|
|
- [Conventional commits](https://www.conventionalcommits.org/) för semantic-release
|
|
- Zod för all validering av API-indata
|
|
- Inga ändringar av Biome-, TypeScript- eller editorkonfigurationsfiler. Fixa koden, inte lintern.
|
|
|
|
## Databas {#database}
|
|
|
|
PostgreSQL 17 via Drizzle ORM (pg-core). Lokal utveckling kräver att Postgres och Redis körs - starta dem med:
|
|
|
|
```bash
|
|
docker compose -f docker-compose.dev.yml up -d
|
|
```
|
|
|
|
Detta ger dig Postgres på port 5432 och Redis på port 6379. Generera sedan och tillämpa migrationer:
|
|
|
|
```bash
|
|
cd apps/api
|
|
npx drizzle-kit generate # generate a migration from schema changes
|
|
npx drizzle-kit migrate # apply pending migrations
|
|
```
|
|
|
|
Schemat definieras i `apps/api/src/db/schema.ts`. Tabeller: users, sessions, settings, jobs, apiKeys, pipelines, teams, userFiles, roles, auditLog.
|
|
|
|
## Lägga till ett nytt verktyg {#adding-a-new-tool}
|
|
|
|
Varje verktyg följer samma mönster. Här är ett minimalt exempel.
|
|
|
|
### 1. Backend-rutt {#_1-backend-route}
|
|
|
|
Skapa `apps/api/src/routes/tools/my-tool.ts`:
|
|
|
|
```ts
|
|
import { z } from "zod";
|
|
import type { FastifyInstance } from "fastify";
|
|
import { createToolRoute } from "../tool-factory.js";
|
|
|
|
const settingsSchema = z.object({
|
|
intensity: z.number().min(0).max(100).default(50),
|
|
});
|
|
|
|
export function registerMyTool(app: FastifyInstance) {
|
|
createToolRoute(app, {
|
|
toolId: "my-tool",
|
|
settingsSchema,
|
|
async process(inputBuffer, settings, filename) {
|
|
// Use sharp or other libraries to process the image
|
|
const sharp = (await import("sharp")).default;
|
|
const result = await sharp(inputBuffer)
|
|
// ... your processing logic
|
|
.toBuffer();
|
|
|
|
return {
|
|
buffer: result,
|
|
filename: filename.replace(/\.[^.]+$/, ".png"),
|
|
contentType: "image/png",
|
|
};
|
|
},
|
|
});
|
|
}
|
|
```
|
|
|
|
Registrera det sedan i `apps/api/src/routes/tools/index.ts`.
|
|
|
|
### 2. Frontend-inställningskomponent {#_2-frontend-settings-component}
|
|
|
|
Skapa `apps/web/src/components/tools/my-tool-settings.tsx`:
|
|
|
|
```tsx
|
|
import { useState } from "react";
|
|
import { useToolProcessor } from "@/hooks/use-tool-processor";
|
|
import { useFileStore } from "@/stores/file-store";
|
|
|
|
export function MyToolSettings() {
|
|
const { files } = useFileStore();
|
|
const { processFiles, processing, error, downloadUrl } =
|
|
useToolProcessor("my-tool");
|
|
|
|
const [intensity, setIntensity] = useState(50);
|
|
|
|
const handleProcess = () => {
|
|
processFiles(files, { intensity });
|
|
};
|
|
|
|
return (
|
|
<div className="space-y-4">
|
|
{/* your controls here */}
|
|
<button
|
|
type="button"
|
|
onClick={handleProcess}
|
|
disabled={files.length === 0 || processing}
|
|
data-testid="my-tool-submit"
|
|
className="w-full py-2.5 rounded-lg bg-primary text-primary-foreground font-medium disabled:opacity-50"
|
|
>
|
|
Process
|
|
</button>
|
|
</div>
|
|
);
|
|
}
|
|
```
|
|
|
|
Registrera det sedan i frontend-verktygsregistret på `apps/web/src/lib/tool-registry.tsx`:
|
|
|
|
```tsx
|
|
// Add the lazy import
|
|
const MyToolSettings = lazy(() =>
|
|
import("@/components/tools/my-tool-settings").then((m) => ({
|
|
default: m.MyToolSettings,
|
|
})),
|
|
);
|
|
|
|
// Add to the toolRegistry Map
|
|
["my-tool", { displayMode: "before-after", Settings: MyToolSettings }],
|
|
```
|
|
|
|
Visningslägen: `"side-by-side"`, `"before-after"`, `"live-preview"`, `"no-comparison"`, `"interactive-crop"`, `"interactive-eraser"`, `"no-dropzone"`.
|
|
|
|
### 3. i18n-post {#_3-i18n-entry}
|
|
|
|
Lägg till i `packages/shared/src/i18n/en.ts`:
|
|
|
|
```ts
|
|
"my-tool": {
|
|
name: "My Tool",
|
|
description: "Short description of what this tool does",
|
|
},
|
|
```
|
|
|
|
### 4. Tester {#_4-tests}
|
|
|
|
Lägg till ett `data-testid`-attribut till din åtgärdsknapp (som visas ovan) så att e2e-tester kan rikta in sig på den tillförlitligt.
|
|
|
|
## Docker-byggen {#docker-builds}
|
|
|
|
Bygg den fullständiga produktionsavbildningen lokalt:
|
|
|
|
```bash
|
|
docker build -f docker/Dockerfile -t snapotter:latest .
|
|
```
|
|
|
|
Använd BuildKit-cache-monteringar för snabbare ombyggen:
|
|
|
|
```bash
|
|
DOCKER_BUILDKIT=1 docker build -f docker/Dockerfile -t snapotter:latest .
|
|
```
|
|
|
|
## Släpp versionsdomäner {#release-version-domains}
|
|
|
|
SnapOtter har avsiktligt tre versionsdomäner. Kopiera inte en domän till en annan under en release:
|
|
|
|
- Applikationsversionen täcker rotmanifestet, alla privata arbetsytepaket och `APP_VERSION`. Semantic-release tillhandahåller detta värde, och `pnpm version:sync <version>` uppdaterar varje arbetsyta innan en applikationsrelease.
|
|
- OpenAPI `info.version` är det stabila offentliga API-stora kontraktet. Alla lokaliserade specifikationer stannar på `<major>.0.0` för kompatibla programversioner och ändras endast när API-kontraktet flyttas till en ny huvudversion.
|
|
- `docker/feature-manifest.json` behåller `imageVersion: 2.0.0` som den oföränderliga äldre lagringsperioden för funktionspaket. Dessa v2-arkivsökvägar är inte programpaketversioner. Exakt OCR använder runtime-format v3 och registrerar applikationsversionens ursprung separat.
|
|
|
|
`tests/unit/infra/release-version-policy.test.ts` upprätthåller dessa gränser. En ny versionsdomän eller migrering måste uppdatera det kontraktet och den relevanta artefaktmigreringsdesignen tillsammans.
|
|
De oberoende API och äldre paketvärden finns i `config/release-version-policy.json`; Synkronisering av programversion får aldrig skriva om den policyfilen implicit.
|
|
|
|
## Miljövariabler {#environment-variables}
|
|
|
|
Se [Konfigurationsguiden](/sv/guide/configuration) för den fullständiga listan. Viktiga för utveckling:
|
|
|
|
| Variabel | Standard | Beskrivning |
|
|
|-----------------------------|-----------|------------------------------------------------|
|
|
| `AUTH_ENABLED` | `true` | Aktivera/inaktivera autentisering |
|
|
| `DEFAULT_USERNAME` | `admin` | Standardadministratörsanvändarnamn |
|
|
| `DEFAULT_PASSWORD` | `admin` | Standardadministratörslösenord |
|
|
| `SKIP_MUST_CHANGE_PASSWORD` | `false` | Hoppa över framtvingat lösenordsbyte (endast CI/dev) |
|
|
| `RATE_LIMIT_PER_MIN` | `1000` | API-hastighetsgräns per minut (0 = inaktiverat) |
|
|
| `MAX_UPLOAD_SIZE_MB` | `100` | Maximal uppladdningsstorlek i MB (0 = obegränsat) |
|
