# Auto Imports

> Automatic imports for utilities and composables.

<code-tree>

```ts [nitro.config.ts]
import { defineConfig } from "nitro";

export default defineConfig({
  serverDir: true,
  imports: {},
});
```

```json [package.json]
{
  "type": "module",
  "scripts": {
    "dev": "nitro dev",
    "build": "nitro build"
  },
  "devDependencies": {
    "nitro": "latest"
  }
}
```

```ts [server.ts]
import { defineHandler } from "nitro";
import { makeGreeting } from "./server/utils/hello.ts";

export default defineHandler(() => `<h1>${makeGreeting("Nitro")}</h1>`);
```

```json [tsconfig.json]
{
  "include": [".nitro/types/nitro-imports.d.ts", "src"]
}
```

```ts [vite.config.ts]
import { defineConfig } from "vite";
import { nitro } from "nitro/vite";

export default defineConfig({ plugins: [nitro()] });
```

```ts [server/utils/hello.ts]
export function makeGreeting(name: string) {
  return `Hello, ${name}!`;
}
```
</code-tree>

Functions exported from `server/utils/` are automatically available without explicit imports when auto-imports are enabled. Define a utility once and use it anywhere in your server code.

## Configuration

Enable auto-imports by setting `imports` in your config:

```ts [nitro.config.ts]
import { defineConfig } from "nitro";

export default defineConfig({
  serverDir: true,
  imports: {},
});
```

## Using Auto Imports

1. Create a utility file in `server/utils/`:

```ts [server/utils/hello.ts]
export function makeGreeting(name: string) {
  return `Hello, ${name}!`;
}
```

2. The function is available without importing it:

```ts [server.ts]
import { defineHandler } from "nitro";

export default defineHandler(() => `<h1>${makeGreeting("Nitro")}</h1>`);
```
With this setup, any function exported from `server/utils/` becomes globally available. Nitro scans the directory and generates the necessary imports automatically.
