What is expo-dev-launcher?

The expo-dev-launcher package is a development tool for Expo applications that allows developers to launch and test their apps in a development environment. It provides functionalities to reload the app, open the developer menu, and handle deep links, among other features.

What are expo-dev-launcher's main functionalities?

Reload the App

This feature allows developers to programmatically reload the application, which is useful for testing changes without manually restarting the app.

async function reloadApp() {
  await reloadAsync();
}

Open Developer Menu

This feature enables developers to open the developer menu programmatically, providing quick access to development tools and options.

import { openMenu } from 'expo-dev-launcher';

function openDevMenu() {
  openMenu();
}

Handle Deep Links

This feature allows the app to handle deep links, making it easier to test and debug deep linking functionality during development.

import { addDeepLinkListener } from 'expo-dev-launcher';

addDeepLinkListener((url) => {
  console.log('Deep link received:', url);
});
