# File-based store



# Overview

The file-based store reads and writes index data to a JSON file on disk. Configure it through [withPeam](/docs/api-reference/next/with-peam) or the CLI. See [Storage](/docs/storage) for selecting a store.

## Options (withPeam)

| Option      | Type     | Default            | Description                                    |
| ----------- | -------- | ------------------ | ---------------------------------------------- |
| `baseDir`   | `string` | `process.cwd()`    | Base directory for the index file.             |
| `indexPath` | `string` | `.peam/index.json` | Path to the index file, relative to `baseDir`. |

## Example (Next.js)

```ts
// next.config.ts
import withPeam from '@peam-ai/next';

export default withPeam({
  searchStore: {
    type: 'fileBased',
    config: { indexPath: '.peam/index.json' },
  },
})();
```

## Example (CLI)

```bash
peam \
  --source fileBased --projectDir . --sourceDir dist \
  --store fileBased --indexPath .peam/index.json
```
