SnapOtterandGitHub d10d0f544f fix: release QA hardening across processing, media, security, and CI gates (#649)
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.

Panduan developer

Cara menyiapkan lingkungan pengembangan lokal dan berkontribusi kode ke SnapOtter.

Prasyarat

  • Node.js 22.22+
  • pnpm 9+ (corepack enable && corepack prepare pnpm@latest --activate)
  • Docker (diperlukan untuk Postgres + Redis lokal, build kontainer, dan fitur AI)
  • Git

Python 3.11+ hanya diperlukan jika Anda mengerjakan sidecar AI/ML (penghapusan latar belakang, upscaling, OCR).

Penyiapan

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

Ini memulai dua server dev:

Layanan URL Catatan
Frontend http://localhost:1351 Server dev Vite, mem-proxy /api
Backend http://localhost:13490 Fastify API (diakses melalui proxy)

Buka http://localhost:1351 di browser Anda. Login dengan admin / admin. Anda akan diminta untuk mengubah kata sandi saat login pertama.

Perintah

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:unit          # unit tests only
pnpm test:integration   # integration tests only
pnpm test:e2e           # Playwright e2e tests
pnpm test:coverage      # tests with coverage report

Konvensi kode

  • Tanda kutip ganda, titik koma, indentasi 2 spasi (ditegakkan oleh Biome)
  • ES module di semua workspace
  • Conventional commits untuk semantic-release
  • Zod untuk semua validasi input API
  • Tidak ada modifikasi pada file konfigurasi Biome, TypeScript, atau editor. Perbaiki kodenya, bukan linter-nya.

Database

PostgreSQL 17 melalui Drizzle ORM (pg-core). Dev lokal memerlukan Postgres dan Redis yang berjalan - mulai keduanya dengan:

docker compose -f docker-compose.dev.yml up -d

Ini memberi Anda Postgres pada port 5432 dan Redis pada port 6379. Kemudian buat dan terapkan migrasi:

cd apps/api
npx drizzle-kit generate   # generate a migration from schema changes
npx drizzle-kit migrate    # apply pending migrations

Skema didefinisikan di apps/api/src/db/schema.ts. Tabel: users, sessions, settings, jobs, apiKeys, pipelines, teams, userFiles, roles, auditLog.

Menambahkan tool baru

Setiap tool mengikuti pola yang sama. Berikut contoh minimal.

1. Route backend

Buat apps/api/src/routes/tools/my-tool.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",
      };
    },
  });
}

Kemudian daftarkan di apps/api/src/routes/tools/index.ts.

2. Komponen pengaturan frontend

Buat apps/web/src/components/tools/my-tool-settings.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>
  );
}

Kemudian daftarkan di registry tool frontend di apps/web/src/lib/tool-registry.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 }],

Mode tampilan: "side-by-side", "before-after", "live-preview", "no-comparison", "interactive-crop", "interactive-eraser", "no-dropzone".

3. Entri i18n

Tambahkan ke packages/shared/src/i18n/en.ts:

"my-tool": {
  name: "My Tool",
  description: "Short description of what this tool does",
},

4. Tes

Tambahkan atribut data-testid ke tombol aksi Anda (seperti ditunjukkan di atas) agar tes e2e dapat menargetkannya secara andal.

Build Docker

Bangun image produksi lengkap secara lokal:

docker build -f docker/Dockerfile -t snapotter:latest .

Gunakan cache mount BuildKit untuk build ulang yang lebih cepat:

DOCKER_BUILDKIT=1 docker build -f docker/Dockerfile -t snapotter:latest .

Rilis domain versi

SnapOtter sengaja memiliki tiga versi domain. Jangan menyalin satu domain ke domain lain selama rilis:

  • Versi rilis aplikasi mencakup manifes root, semua paket ruang kerja pribadi, dan APP_VERSION. Semantic-release menyediakan nilai ini, dan pnpm version:sync <version> memperbarui setiap ruang kerja sebelum aplikasi dirilis.
  • OpenAPI info.version adalah kontrak utama publik API yang stabil. Semua spesifikasi yang dilokalkan tetap pada <major>.0.0 untuk rilis aplikasi yang kompatibel dan hanya berubah ketika kontrak API berpindah ke versi utama baru.
  • docker/feature-manifest.json menjadikan imageVersion: 2.0.0 sebagai masa penyimpanan paket fitur lama yang tidak dapat diubah. Jalur arsip v2 tersebut bukan versi paket aplikasi. OCR yang akurat menggunakan format runtime v3 dan mencatat asal rilis aplikasinya secara terpisah.

tests/unit/infra/release-version-policy.test.ts menerapkan batasan ini. Domain atau migrasi versi baru harus memperbarui kontrak tersebut dan desain migrasi artefak yang relevan secara bersamaan. Nilai API independen dan paket warisan ada di config/release-version-policy.json; sinkronisasi versi aplikasi tidak boleh menulis ulang file kebijakan tersebut secara implisit.
