Richard R 9b9206f50d refactor(audiobooks): migrate audiobook pipeline to object storage
This commit restructures the audiobook generation and serving layer to rely exclusively on S3-compatible blob storage, removing the dependency on local filesystem paths.

- Bundle `ffmpeg` and `ffprobe` binaries via npm to ensure portability across environments.
- Update API routes to stream audio directly from blob storage instead of local disk.
- Remove legacy migration endpoints and filesystem-based indexing logic.
- Add startup scripts to facilitate the transition from local to remote storage.

BREAKING CHANGE: Audiobook functionality is now strictly dependent on S3 configuration. The previous filesystem-based storage method has been removed.

title: Local Development

## Prerequisites
- Node.js (recommended with [nvm](https://github.com/nvm-sh/nvm))
- `pnpm` (recommended) or `npm`
```bash
npm install -g pnpm
```
- A reachable TTS API server
- [SeaweedFS](https://github.com/seaweedfs/seaweedfs) `weed` binary (required)
```bash
brew install seaweedfs
```
Optional, depending on features:
- [libreoffice](https://www.libreoffice.org) (required for DOCX conversion)
```bash
brew install libreoffice
```
- [whisper.cpp](https://github.com/ggml-org/whisper.cpp) (optional, for word-by-word highlighting)
```bash
# clone and build whisper.cpp (no model download needed OpenReader handles that)
git clone https://github.com/ggml-org/whisper.cpp.git
cd whisper.cpp
cmake -B build
cmake --build build -j --config Release
# point OpenReader to the compiled whisper-cli binary
echo WHISPER_CPP_BIN="$(pwd)/build/bin/whisper-cli"
```
:::note
Set `WHISPER_CPP_BIN` in your `.env` to enable word-by-word highlighting.
:::
## Steps
1. Clone the repository.
```bash
git clone https://github.com/richardr1126/OpenReader-WebUI.git
cd OpenReader-WebUI
```
2. Install dependencies.
```bash
pnpm i
```
3. Configure the environment.
```bash
cp .env.example .env
```
Then edit `.env`.
Auth is enabled when both are set:
- `BASE_URL` (for local dev, typically `http://localhost:3003`)
- `AUTH_SECRET` (generate with `openssl rand -base64 32`)
Optional:
- `AUTH_TRUSTED_ORIGINS=http://localhost:3003,http://192.168.0.116:3003`
- Stable S3 credentials via `S3_ACCESS_KEY_ID` and `S3_SECRET_ACCESS_KEY`
- External S3 storage by setting `USE_EMBEDDED_WEED_MINI=false` and related S3 vars
For all environment variables, see [Environment Variables](../reference/environment-variables).
For app/auth behavior, see [Auth](../configure/configuration).
For storage configuration, see [Object / Blob Storage](../configure/storage-and-blob-behavior).
For database mode and migrations, see [Database and Migrations](../configure/database-and-migrations).
4. Run DB migrations.
- Migrations run automatically on startup through the shared entrypoint for both `pnpm dev` and `pnpm start`.
- You only need manual migration commands for one-off troubleshooting or explicit migration workflows:
```bash
pnpm migrate
```
:::note
If `POSTGRES_URL` is set, migrations target Postgres; otherwise local SQLite is used. To disable automatic startup migrations, set `RUN_DRIZZLE_MIGRATIONS=false` and/or `RUN_FS_MIGRATIONS=false`. You can run storage migration manually with `pnpm migrate-fs`.
:::
5. Start the app.
```bash
pnpm dev
```
Or build + start production mode:
```bash
pnpm build
pnpm start
```
