A Nuxt module aimed to simplify the use of [SurrealDB](https://surrealdb.com), wrapping the official [surrealdb.js](https://github.com/surrealdb/surrealdb.js) SDK.

- [✨  Release Notes](/CHANGELOG.md)
- [📖  Documentation](https://nuxt-surrealdb.s94.dev)

## Quick Setup

Install the module to your Nuxt application:

```bash
npx nuxi module add nuxt-surrealdb
```

Configure your SurrealDB endpoint in `nuxt.config.ts`:

```ts
export default defineNuxtConfig({
  modules: ['nuxt-surrealdb'],
  surrealdb: {
    client: {
      endpoint: 'http://localhost:8000',
      connectOptions: {
        namespace: 'my_ns',
        database: 'my_db',
      },
    },
  },
})
```

## Features

- 🔌 Wraps the official **surrealdb.js** SDK with auto-imported composables and server utils
- 🧩 SSR-safe composables: `useSurrealQuery`, `useSurrealSelect`, `useSurrealAuth`, and more — all built on top of Nuxt's `useAsyncData`
- 🖥️ Server utils with per-request session support via `useSurreal(event)` in Nitro event handlers
- ⚡️ Embedded engines: run SurrealDB in-process with `@surrealdb/wasm` (client) or `@surrealdb/node` (server) for in-memory and local persistent storage
- 🪝 Lifecycle hooks via `surrealHooks` for connection setup, authentication, and schema initialization
- 📦 Auto-import of SurrealDB SDK classes (`RecordId`, `Table`, `Uuid`, etc.) and expression helpers (`eq`, `gt`, `contains`, etc.)
- 🔧 Full configuration via `nuxt.config.ts` or environment variables

## Composables

### Client-side

| Composable | Description |
|------------|-------------|
| `useSurreal()` | Get the connected `Surreal` client |
| `useSurrealAsyncData(cb)` | Low-level SSR-safe wrapper around `useAsyncData` |
| `useSurrealQuery(query, bindings?)` | Execute a SurrealQL query with SSR support |
| `useSurrealSelect(table, builder?)` | Select records with a builder-pattern API |
| `useSurrealAuth()` | Get the currently authenticated user info |
| `useSurrealRun(name, args?)` | Execute a SurrealDB function |
| `useSurrealVersion()` | Get the SurrealDB server version |
| `useSurrealExport(options?)` | Export the database |
| `useSurrealImport(input)` | Import a SurrealQL dump |
| `useSurrealMemory()` | Access the in-memory WASM client |
| `useSurrealLocal()` | Access the local WASM client |

### Server-side

| Util | Description |
|------|-------------|
| `useSurreal()` / `useSurreal(event)` | Get the remote client or a per-request session |
| `useSurrealMemory()` / `useSurrealMemory(event)` | In-memory Node engine (requires `@surrealdb/node`) |
| `useSurrealLocal()` / `useSurrealLocal(event)` | Local persistent Node engine (requires `@surrealdb/node`) |

## Environment Variables

Configuration maps to Nuxt runtime config. Override values using env vars:

```dotenv
# Client (public)
NUXT_PUBLIC_SURREALDB_ENDPOINT="http://localhost:8000"
NUXT_PUBLIC_SURREALDB_CONNECT_OPTIONS_NAMESPACE="my_ns"
NUXT_PUBLIC_SURREALDB_CONNECT_OPTIONS_DATABASE="my_db"

# Server-only
NUXT_SURREALDB_ENDPOINT="http://internal-surrealdb:8000"
NUXT_SURREALDB_SESSION="new"
NUXT_SURREALDB_LOCAL_ENDPOINT="surrealkv://./.data/db"
```

## Optional Dependencies

| Package | Purpose |
|---------|---------|
| `@surrealdb/wasm` | Client-side embedded engines (in-memory, IndexedDB) |
| `@surrealdb/node` | Server-side embedded engines (in-memory, SurrealKV) |

> [!WARNING]
> The IndexedDB (`indxdb://`) WASM engine is currently bugged upstream. In-memory mode works as expected.
