# chdb-bun 

Experimental [chDB](https://github.com/chdb-io/chdb) FFI bindings for the [bun runtime](https://bun.sh)

### Status

- experimental, unstable, subject to changes

- requires [`libchdb`](https://github.com/chdb-io/chdb) on the system

- requires `gcc` or `clang`

#### Build binding

```bash

bun run build

bun run example.ts

```

#### Usage

#### Query(query, *format) (ephemeral)

```javascript

import { query } from 'chdb-bun';

// Query (ephemeral)

var result = query("SELECT version()", "CSV");

console.log(result); // 23.10.1.1

```

#### Session.Query(query, *format)

```javascript

import { Session } from 'chdb-bun';

const sess = new Session('./chdb-bun-tmp');

// Query Session (persistent)

sess.query("CREATE FUNCTION IF NOT EXISTS hello AS () -> 'Hello chDB'", "CSV");

var result = sess.query("SELECT hello()", "CSV");

console.log(result);

// Before cleanup, you can find the database files in `./chdb-bun-tmp`

sess.cleanup(); // cleanup session, this will delete the database

```
