The codebase already has two well-established job-tracking patterns (`heartbeat_runs`, `plugin_job_runs`) and a working SSE streaming pattern in three routes (`voice.ts`, `puter-proxy.ts`, `plugins.ts`). The work here is additive: a new `content_jobs` DB table, a minimal in-process job runner, new live-event types for SSE progress, a `generated/` storage namespace with its own size constant, and a `source_task_id` column on `assets`. + +No external queue infrastructure (Redis, BullMQ) is needed. The project is single-user and local-first. An in-process async runner (fire-and-forget `void Promise`) with EventEmitter fan-out — matching the heartbeat pattern — is the correct approach. If a job crashes the process restarts clean; orphan prevention is via `source_task_id` so consumers can audit. + +**Primary recommendation:** Mirror the `heartbeat_runs` table/service pattern for the `content_jobs` table. Use the existing `publishLiveEvent` function with new `content_job.*` event types for SSE. Add `MAX_GENERATED_ASSET_BYTES` as a server-only constant and a `generated/` namespace prefix.

Job runners write directly to `storage.putFile()` — multer is never involved. The `MAX_GENERATED_ASSET_BYTES` constant exists for the job runner to validate before calling `putFile`, but `putFile` itself has no byte limit. + +### Pattern 6: source_task_id on assets (INFRA-04) + +**What:** Nullable column added to `assets` table. +**When to use:** Every asset created by a job runner must pass `sourceTaskId`. + +```typescript +// packages/db/src/schema/assets.ts — add column: +sourceTaskId: text("source_task_id"), // nullable, no FK — task IDs are string identifiers + +// assetService.create() in server/src/services/assets.ts accepts it through +// the existing spread pattern: db.insert(assets).values({ ...data, companyId }) +// since the column is nullable, no callers break. +``` + +### Pattern 7: content-job-store.ts (service layer) + +**What:** CRUD service for content_jobs table. +**When to use:** Create and update jobs from routes + runner. + +```typescript +// server/src/services/content-job-store.ts +// Pattern source: server/src/services/assets.ts, heartbeat.ts +export function contentJobStore(db: Db) { + return { + create: (companyId: string, data: { jobType: string; input: Record; sourceTaskId: string | null }) => + db.insert(contentJobs).values({ companyId, ...data }).returning().then((r) => r[0]), + + getById: (id: string) => + db.select().from(contentJobs).where(eq(contentJobs.id, id)).then((r) => r[0] ?? null), + + listByCompany: (companyId: string) => + db.select().from(contentJobs) + .where(eq(contentJobs.companyId, companyId)) + .orderBy(desc(contentJobs.createdAt)), + + transition: (id: string, patch: Partial) => + db.update(contentJobs).set({ ...patch, updatedAt: new Date() }).where(eq(contentJobs.id, id)), + }; +} +``` + +### Anti-Patterns to Avoid + +- **Awaiting render in HTTP handler:** Never `await renderer.run()` in the route handler.

The runner calls `storage.putFile()` directly — no multer anywhere. The size check (`MAX_GENERATED_ASSET_BYTES`) belongs in the job runner, after rendering, before writing. +**Warning signs:** Any import of `multer` in `content-jobs.ts` or `content-job-runner.ts`. + +### Pitfall 2: SSE connection leaking if client disconnects mid-job + +**What goes wrong:** Client disconnects; the `unsubscribe` callback is never called; the EventEmitter listener accumulates. With many requests this can trigger Node's MaxListeners warning. +**Why it happens:** SSE streams need explicit `req.on("close")` cleanup. +**How to avoid:** Always register `req.on("close", () => { unsubscribe(); })` in every SSE handler. See `live-events-ws.ts` `cleanupByClient` pattern. +**Warning signs:** MaxListeners exceeded warning in server logs. + +### Pitfall 3: Publishing live events before the DB row is committed + +**What goes wrong:** Browser receives `content_job.done` event, queries `/content-jobs/:id`, gets stale data (or 404 if the row hasn't flushed). +**Why it happens:** `publishLiveEvent` is synchronous; the DB write is async. +**How to avoid:** Always `await db.update(...)` before calling `publishLiveEvent(...)` in the job runner. +**Warning signs:** Frontend shows "done" but API returns "running". + +### Pitfall 4: Migration numbering collision + +**What goes wrong:** Two migrations are created with the same prefix (e.g., `0056_`) and drizzle-kit fails to apply them in order. +**Why it happens:** Parallel development or rebasing creates numbering conflicts. +**How to avoid:** Check `ls packages/db/src/migrations/` before running `pnpm db:generate`. The last file is currently `0055_create_push_subscriptions.sql`.

The full fluent API is unnecessary — format conversion is a single `ffmpeg -i input.mp4 output.webm` call. + +```typescript +// server/src/services/converters/ffmpeg-converter.ts +import { spawn } from "child_process"; +import ffmpegPath from "ffmpeg-static"; + +export function ffmpegConvert( + inputPath: string, + outputPath: string, + extraArgs: string[] = [] +): Promise { + return new Promise((resolve, reject) => { + const proc = spawn(ffmpegPath!, [ + "-i", inputPath, + ...extraArgs, + "-y", // overwrite output + outputPath, + ]); + proc.on("close", (code) => + code === 0 ? resolve() : reject(new Error(`ffmpeg exited ${code}`)) + ); + proc.stderr.on("data", () => {}); // consume stderr to prevent backpressure + }); +} +``` + +**Format coverage via ffmpeg-static:** + +| Source | Target | Extra args | +|--------|--------|-----------| +| MP4/MKV/AVI/MOV | WebM | `["-c:v", "libvpx-vp9", "-c:a", "libopus"]` | +| MP4/WebM | MP3/AAC | `["-vn", "-c:a", "libmp3lame"]` (audio extract) | +| MP3/WAV/FLAC/OGG | MP3 | `["-c:a", "libmp3lame", "-b:a", "192k"]` | +| MP3/WAV/OGG | WAV | `["-c:a", "pcm_s16le"]` | +| Image sequence | MP4 | `["-r", "30", "-c:v", "libx264"]` | +| MP4 | GIF | `["-vf", "fps=10,scale=640:-1:flags=lanczos"]` | +| Any video | Audio-only MP3 | `["-vn"]` | + +--- + +### Documents + +#### DOCX to HTML: `mammoth ^1.12.0` + +Mammoth converts `.docx` → HTML with semantic preservation. It does NOT create DOCX. + +```bash +pnpm --filter @paperclipai/server add mammoth +``` + +```typescript +import mammoth from "mammoth"; + +const { value: html } = await mammoth.convertToHtml({ path: docxPath }); +// html is a clean HTML string; images are embedded as base64 data URIs by default +``` + +**Why mammoth over pandoc for DOCX→HTML:** Mammoth preserves heading hierarchy, tables, lists, and images correctly. Its output is cleaner HTML than pandoc's for Word documents. Single-purpose library, no system binary required. + +**TypeScript types:** Included in the package since v1.7 (`@types/mammoth` not needed). + +**Confidence: HIGH** — official npm, v1.12.0, actively maintained (last publish 20 days ago). + +--- + +#### Markdown → DOCX / PDF / HTML: Pandoc (system binary + thin wrapper) + +**Integration approach:** Pandoc is a Haskell binary — there is no pure-Node.js implementation. Existing Node.js wrappers are thin `child_process` shims: + +- `node-pandoc ^0.2.7` — 13K weekly downloads, most popular, but last updated 2021 +- `pandoc-ts` — TypeScript wrapper, smaller community +- **Recommended: write a 20-line `child_process.spawn` wrapper** — same as ffmpeg approach + +```typescript +// server/src/services/converters/pandoc-converter.ts +import { spawn } from "child_process"; + +export function pandocConvert( + inputPath: string, + outputPath: string, + from: string, + to: string +): Promise { + return new Promise((resolve, reject) => { + const proc = spawn("pandoc", [ + inputPath, + "-f", from, + "-t", to, + "-o", outputPath, + ]); + proc.on("close", (code) => + code === 0 ? resolve() : reject(new Error(`pandoc exited ${code}`)) + ); + }); +} +``` + +**Supported format pairs via pandoc:** + +| Source | Target | +|--------|--------| +| Markdown | DOCX, HTML, RST, LaTeX, EPUB | +| RST | Markdown, HTML, DOCX | +| HTML | Markdown, DOCX | +| LaTeX | HTML, Markdown | +| DOCX | Markdown (lossier than mammoth for HTML) | + +**System dependency:** pandoc must be installed on the Mac Mini. Install via `brew install pandoc`. Check at server startup with `which pandoc`; if absent, degrade gracefully. + +**Confidence: HIGH** — pandoc is the de-facto standard; brew install is 1 command; child_process wrapper is trivial. + +--- + +#### DOCX / ODT / PPTX → PDF: LibreOffice headless + +**Package: `libreoffice-convert ^1.8.1`** + +```bash +pnpm --filter @paperclipai/server add libreoffice-convert +# System dependency: brew install --cask libreoffice +``` + +```typescript +import { convertAsync } from "libreoffice-convert"; +import fs from "fs/promises"; + +const inputBuffer = await fs.readFile(docxPath); +const pdfBuffer = await convertAsync(inputBuffer, ".pdf", undefined); +``` + +**Format pairs:** + +| Source | Target | +|--------|--------| +| DOCX / DOC | PDF, ODT, HTML | +| PPTX / PPT | PDF, ODP | +| XLSX / XLS | PDF, ODS, CSV | +| ODT / ODP / ODS | PDF, DOCX, PPTX | + +**Performance warning:** LibreOffice launches a JVM-equivalent runtime on first call. Cold start: ~3-5 seconds. Warm subsequent calls: ~500ms. Serialize LibreOffice jobs (no concurrent renders) — run maximum one at a time. + +**System dependency:** LibreOffice must be installed at `/Applications/LibreOffice.app` on macOS. Check at server startup; degrade gracefully if absent. + +**Confidence: MEDIUM** — package v1.8.1 confirmed. macOS arm64 LibreOffice runs natively on M4 (confirmed via LibreOffice download page). Single source for LibreOffice npm package maintenance status. + +--- + +#### HTML → PDF: playwright-chromium (already decided in STACK.md) + +Use `playwright-chromium ^1.50.0` for HTML→PDF. Already researched; do not re-add. + +--- + +### Data Formats + +#### Spreadsheets: `xlsx` (SheetJS Community Edition) + +**Package: `xlsx ^0.20.x`** (SheetJS Community Edition) + +```bash +pnpm --filter @paperclipai/server add xlsx +``` + +**Format coverage:** + +| Source | Target | Method | +|--------|--------|--------| +| XLSX / XLS / ODS | CSV | `XLSX.utils.sheet_to_csv(ws)` | +| XLSX / XLS / ODS | JSON | `XLSX.utils.sheet_to_json(ws)` | +| CSV / JSON | XLSX | `XLSX.utils.json_to_sheet(data)` → `XLSX.writeFile(wb, path)` | + +SheetJS has ~7.8M weekly downloads and handles all Excel formats including legacy `.xls`. It is the default choice with no alternatives needed for basic spreadsheet conversion. + +**Licensing note:** SheetJS Community Edition is free (Apache 2.0 for historical versions; check current license at install time). SheetJS Pro adds streaming for very large files — not needed at single-user scale. + +**Confidence: MEDIUM-HIGH** — widely used, 7.8M weekly downloads confirmed. Version 0.20.x confirmed. License nuance warrants a check at install time. + +--- + +#### CSV Parsing: `csv-parse ^5.6.0` (part of the `csv` ecosystem) + +```bash +pnpm --filter @paperclipai/server add csv-parse +``` + +The `csv-parse ^6.2.1` package (latest as of April 2026) implements `stream.Transform` and supports both streaming and synchronous/callback modes. It includes TypeScript types. + +**When to use:** Parsing user-uploaded CSV files before transformation (CSV→JSON, CSV→XLSX). For generating CSV output from JSON/objects, use SheetJS or `csv-stringify` (same ecosystem as `csv-parse`). + +**Confidence: HIGH** — v6.2.1 confirmed from npm search. Maintained (last publish 4 days ago). + +--- + +#### JSON ↔ CSV: Use `csv-parse` + `csv-stringify` (not `json2csv`) + +The `json2csv` package is in maintenance mode at v6.0.0-alpha (3 years old). The `json-2-csv` package (v5.5.10, different package) is active but adds a dependency for something `csv-stringify` already handles. + +**Recommendation:** Use `csv-stringify ^6.x` (same ecosystem as `csv-parse`, same maintainer) for JSON→CSV. This avoids pulling in a separate package. + +```bash +pnpm --filter @paperclipai/server add csv-stringify +``` + +--- + +### Code Formats + +#### Code Formatting (JS/TS/CSS/HTML): `prettier ^3.x` + +```bash +pnpm --filter @paperclipai/server add --save-dev prettier +# For programmatic use in server: +pnpm --filter @paperclipai/server add prettier +``` + +Prettier exposes a programmatic API: + +```typescript +import { format } from "prettier"; + +const formatted = await format(sourceCode, { + parser: "typescript", // or "babel", "css", "html", "markdown", etc. + semi: true, + singleQuote: true, +}); +``` + +**Use case:** Agent generates code → prettier formats it before saving. Also enables code→code conversions like "reformat this JSON" or "convert CommonJS to ESM style." + +**Confidence: HIGH** — Prettier API is well-documented at prettier.io/docs/api. + +--- + +#### TypeScript Type Generation (JSON Schema → TypeScript): `json-schema-to-typescript ^15.x` + +For the AI-bridged case where an agent converts a JSON schema into TypeScript type definitions, this library handles it deterministically: + +```bash +pnpm --filter @paperclipai/server add json-schema-to-typescript +``` + +```typescript +import { compile } from "json-schema-to-typescript"; +const ts = await compile(jsonSchema, "MyType"); +``` + +**Confidence: MEDIUM** — widely used library; version verified as 15.x on npm (as of late 2025).

See Tier 2 below. + +--- + +## Tier 2: Format Registry Pattern + +### Dispatch Table Design + +The registry is a map of `"source/target"` → handler function. This is simpler than a class hierarchy and matches the existing Nexus factory function pattern. + +```typescript +// server/src/services/converters/registry.ts + +export type ConversionHandler = ( + inputPath: string, + outputPath: string, + opts?: Record +) => Promise; + +export type ConversionCapability = "direct" | "ai-bridged" | "unavailable"; + +export interface ConversionRoute { + capability: ConversionCapability; + handler?: ConversionHandler; // present when capability = "direct" + aiHint?: string; // present when capability = "ai-bridged" + requiresSystemDep?: string; // e.g. "pandoc", "libreoffice" +} + +// Key format: "source.ext/target.ext" — always lowercase, no leading dot +const registry = new Map(); + +export function registerConverter( + sourceExt: string, + targetExt: string, + route: ConversionRoute +): void { + registry.set(`${sourceExt}/${targetExt}`, route); +} + +export function getConverter(sourceExt: string, targetExt: string): ConversionRoute { + return registry.get(`${sourceExt}/${targetExt}`) ?? { capability: "unavailable" }; +} + +export function listSupportedTargets(sourceExt: string): string[] { + const results: string[] = []; + for (const [key, route] of registry.entries()) { + if (key.startsWith(`${sourceExt}/`) && route.capability !== "unavailable") { + results.push(key.split("/")[1]); + } + } + return results; +} +``` + +**Registration (in server startup):** + +```typescript +// server/src/services/converters/index.ts +import { registerConverter } from "./registry"; +import { sharpConvert } from "./sharp-converter"; +import { ffmpegConvert } from "./ffmpeg-converter"; +import { pandocConvert } from "./pandoc-converter"; + +// Image +registerConverter("png", "webp", { capability: "direct", handler: (i, o) => sharpConvert(i, o, "webp") }); +registerConverter("jpg", "webp", { capability: "direct", handler: (i, o) => sharpConvert(i, o, "webp") }); +registerConverter("svg", "png", { capability: "direct", handler: (i, o) => sharpConvert(i, o, "png") }); + +// Documents +registerConverter("docx", "html", { capability: "direct", handler: mammothConvert, requiresSystemDep: undefined }); +registerConverter("docx", "pdf", { capability: "direct", handler: libreofficeConvert, requiresSystemDep: "libreoffice" }); +registerConverter("md", "docx", { capability: "direct", handler: (i, o) => pandocConvert(i, o, "markdown", "docx"), requiresSystemDep: "pandoc" }); + +// Data +registerConverter("xlsx", "csv", { capability: "direct", handler: sheetjsConvert }); +registerConverter("csv", "xlsx", { capability: "direct", handler: sheetjsConvert }); +registerConverter("csv", "pdf", { capability: "ai-bridged", aiHint: "format as a formatted table report PDF" }); +registerConverter("json", "pdf", { capability: "ai-bridged", aiHint: "render as a structured document report" }); + +// Audio/Video +registerConverter("mp4", "webm", { capability: "direct", handler: (i, o) => ffmpegConvert(i, o, ["-c:v", "libvpx-vp9"]) }); +registerConverter("mp3", "wav", { capability: "direct", handler: (i, o) => ffmpegConvert(i, o, ["-c:a", "pcm_s16le"]) }); +``` + +**Extensibility:** Adding a new format pair is one `registerConverter()` call. The route handler and the registry are decoupled. System dependency checks happen at `registerConverter()` time, not at request time — unavailable converters are registered as `capability: "unavailable"` when their system dep is absent. + +--- + +## Tier 2: AI-Bridged Conversion + +### When to Use AI (vs Direct Tool) + +| Criterion | Direct Tool | AI-Bridged | +|-----------|-------------|------------| +| Output is byte-for-byte deterministic | Yes | No | +| Format pair has an established tool | Yes | No | +| Conversion is purely structural (no semantic change) | Yes | — | +| Conversion requires understanding content meaning | — | Yes | +| Source format is machine-readable but lacks a direct path | — | Yes | +| Example pairs | PNG→WebP, DOCX→PDF, MP4→WebM | CSV→PDF report, JSON→DOCX narrative, schema→TypeScript | + +**Decision rule:** + +> Use direct tool when: `getConverter(src, tgt).capability === "direct"`. +> Use AI when: capability is `"ai-bridged"` AND the source is a text/data format that an LLM can read as context. +> Return `"unavailable"` error when: capability is `"unavailable"` (binary formats with no path, e.g. PDF→XLSX). + +**AI-bridged is NOT a fallback for when a tool is missing.** If LibreOffice is not installed, DOCX→PDF is `"unavailable"`, not `"ai-bridged"`. AI-bridged is only for semantically complex conversions where no deterministic tool exists. + +--- + +### AI-Bridged Prompt Structure + +The prompt must be deterministic in its output format requirements.
