title: Vercel Deployment
|

|
This guide covers deploying OpenReader WebUI to Vercel with external Postgres and S3-compatible object storage.
|
|
|
|
## What works on Vercel
|
|
|
|
- Documents (PDF/EPUB/TXT/MD) work with `POSTGRES_URL` + external S3 storage.
|
|
- Audiobook routes work on Node.js serverless functions using `ffmpeg-static`/`ffprobe-static`.
|
|
|
|
:::warning DOCX Conversion Limitation
|
|
`docx` conversion requires `soffice` (LibreOffice), which is not available in a standard Vercel runtime.
|
|

## 1. Environment Variables

## 2. FFmpeg/ffprobe packaging in Vercel functions
|
|
|
|
`ffmpeg-static` and `ffprobe-static` binaries must be included in function traces. This repo already does that in `next.config.ts` via `outputFileTracingIncludes` for:
|
|
|
|
- `/api/audiobook`
|
|
- `/api/audiobook/chapter`
|
|
- `/api/audiobook/status`
|
|
- `/api/whisper`
|
|
|
|
:::info
|
|
`serverExternalPackages` should include `ffmpeg-static` and `ffprobe-static` so package paths resolve at runtime instead of being bundled into route output.
|
|
:::
|
|
|
|
If you change route paths or split handlers, update `outputFileTracingIncludes` accordingly.
|
|
|
|
## 3. Function memory sizing
|
|
|
|
FFmpeg workloads benefit from more memory/CPU. This repo includes:
|
|
|
|
```json
|
|
{
|
|
"$schema": "https://openapi.vercel.sh/vercel.json",
|
|
"functions": {
|
|
"app/api/audiobook/route.ts": { "memory": 3009 },
|
|
"app/api/whisper/route.ts": { "memory": 3009 }
|
|
}
|
|
}
|
|
```
|
|
|
|
Adjust memory per route if your files are larger or your plan differs.
|
|
|
|
## 4. Runtime expectations and caveats
|
|
|
|
- Audiobook APIs require S3 configuration; otherwise they return `503`.
|
|
- For production Vercel deploys, use `POSTGRES_URL` instead of SQLite.
|
|
- Filesystem-to-object-store migrations run via server scripts/entrypoint (`scripts/migrate-fs-v2.mjs`), not API routes.
|
|
- Vercel deployments do not run `scripts/openreader-entrypoint.mjs`, so run `pnpm migrate-fs` in a controlled environment when migrating legacy filesystem data.
|
|
|
|
## 5. Smoke test after deploy
|
|
|
|
1. Upload and read a PDF/EPUB document.
|
|
2. Confirm sync/blob fetch works across refreshes/devices.
|
|
3. Generate at least one audiobook chapter and play/download it.
|
|
4. If using word highlighting, verify timestamps are produced and rendered.
