# backend
|
||
|
||
## Overview
|
||
Backend for the video upload prototype providing:
|
||
|
||
- Better Auth email/password authentication
|
||
- Presigned MinIO uploads/downloads
|
||
- An authenticated video administration surface at `/admin`
|
||
|
||
## Requirements
|
||
- [Bun](https://bun.sh) (tooling used for running scripts & dependency management)
|
||
- Postgres reachable via `DATABASE_URL`
|
||
- MinIO-compatible storage reachable via `MINIO_*` env vars
|
||
- `.env` file populated with secrets and credentials
|
||
|
||
## Install
|
||
```bash
|
||
bun install
|
||
```
|
||
|
||
## Configuration
|
||
Copy the example environment file and adjust the values:
|
||
|
||
```bash
|
||
cp .env.example .env
|
||
```
|
||
|
||
Required env vars:
|
||
|
||
| Name | Purpose |
|
||
| --- | --- |
|
||
| `DATABASE_URL` | Postgres connection string |
|
||
| `BETTER_AUTH_SECRET` | Secret used to sign sessions |
|
||
| `BETTER_AUTH_URL` | Public base URL for the backend (e.g., `http://localhost:3000`) |
|
||
| `BETTER_AUTH_TRUSTED_ORIGINS` | Comma-separated list of allowed frontend origins |
|
||
| `PORT` | HTTP port (default `3000`) |
|
||
| `MINIO_*` | Connection settings for the MinIO/S3 endpoint |
|
||
| `ADMIN_USERNAME` / `ADMIN_PASSWORD` | Basic auth for `/admin` dashboard |
|
||
|
||
## Running
|
||
- Start the server in development:
|
||
|
||
```bash
|
||
bun run dev
|
||
```
|
||
|
||
- Server boots after ensuring the configured MinIO bucket exists.
|
||
|
||
## Database (Drizzle ORM)
|
||
- Generate a migration:
|
||
```bash
|
||
bun run db:generate
|
||
```
|
||
- Apply migrations:
|
||
```bash
|
||
bun run db:migrate
|
||
```
|
||
- Backfill Better Auth credential accounts for existing users:
|
||
```bash
|
||
bun run auth:migrate
|
||
```
|
||
- Open Drizzle Studio:
|
||
```bash
|
||
bun run db:studio
|
||
```
|
||
|
||
## API
|
||
All `/videos` and `/admin` routes require a valid Better Auth session except for the admin dashboard access, which uses HTTP Basic auth with `ADMIN_USERNAME`/`ADMIN_PASSWORD`.
|
||
|
||
### Authentication
|
||
Authentication is handled by Better Auth under `/api/auth/*` (for example `/api/auth/sign-in` and `/api/auth/sign-up`).
|
||
|
||
### Authorization
|
||
All authenticated endpoints expect a Better Auth session cookie sent by the client.
|
||
|
||
### Video Management
|
||
| Endpoint | Purpose |
|
||
| --- | --- |
|
||
| `POST /videos/upload-url` | Request a presigned PUT URL for a new video |
|
||
| `GET /videos/download-url` | Generate a signed GET URL to download a video |
|
||
| `GET /videos` | List objects in the configured bucket |
|
||
| `DELETE /videos` | Delete an object by `objectKey` |
|
||
|
||
### Admin Dashboard
|
||
Access `/admin` with Basic auth to:
|
||
|
||
- Request presigned upload URLs
|
||
- Upload files directly via the generated URL
|
||
- List and delete objects within the MinIO bucket
|
||
|
||
The dashboard UI submits to `/admin/upload-url`, `/admin/objects`, and `/admin/object`.
|
||
|
||
## Schema
|
||
- `users` – email/username/password and timestamps
|
||
- `events` – user-created events with a unique `videoUrl`
|
||
- `videos` – upload metadata including `objectKey`, bucket, URLs, status, and timestamps
|
||
|
||
## Notes
|
||
- MinIO bucket creation happens during startup, so the service must be able to reach the endpoint.
|
||
- Keep Better Auth and MinIO secrets out of source control.
