# DevServer

Re.Pack 5 has it's own dev server that contain all features as Metro packager does, or even more in some cases.

## Features

Re.Pack's dev server supports both Rspack and webpack and provides essential development features:

- **Hot Module Reloading**: Instantly reflects code changes in the app
- **Source Maps**: Enables proper debugging with source code mapping
- **Multiple Platforms**: Supports both iOS and Android development
- **Development Tools**: Integrated with React Native DevTools

:::tip Looking for DevServer configuration?

For complete DevServer configuration options and API reference, check out the [DevServer API documentation](/api/dev-server.md).

:::

## Usage

To start the dev server, you can use the following command:


```sh [npm]
npm run react-native start
```

```sh [yarn]
yarn react-native start
```

```sh [pnpm]
pnpm react-native start
```

```sh [bun]
bun react-native start
```

To get the full list of options available, check out the [`start`](/api/cli/start.md)'s command documentation.

:::info

The command is started through the React Native Community CLI's `start` command, which is overridden [inside `react-native.config.js`](/docs/getting-started/quick-start.md#2-commands) to spawn Re.Pack's dev server.

### Automatic ADB reverse

Re.Pack automatically handles ADB reverse port forwarding for Android development. When starting the dev server, it will wait for devices to be connected (`adb wait-for-device`) and then automatically run `adb reverse` on all connected Android devices.

### Keyboard shortcuts

You can use various keyboard shortcuts inside a terminal to interact with the dev server.
