This is a new [**React Native**](https://reactnative.dev) project, bootstrapped using [`@react-native-community/cli`](https://github.com/react-native-community/cli).
|
||
|
|
|
||
|
|
# Getting Started
|
||
|
|
|
||
|
|
>**Note**: Make sure you have completed the [React Native - Environment Setup](https://reactnative.dev/docs/environment-setup) instructions till "Creating a new application" step, before proceeding.
|
||
|
|
|
||
|
|
## Requirement
|
||
|
|
- Node JS: v20.9.0
|
||
|
|
- Java version: 11
|
||
|
|
|
||
|
|
## Step 1: Start the Metro Server
|
||
|
|
|
||
|
|
First, you will need to start **Metro**, the JavaScript _bundler_ that ships _with_ React Native.
|
||
|
|
|
||
|
|
To start Metro, run the following command from the _root_ of your React Native project:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# using npm
|
||
|
|
npm start
|
||
|
|
|
||
|
|
# OR using Yarn
|
||
|
|
yarn start
|
||
|
|
```
|
||
|
|
|
||
|
|
## Step 2: Start your Application
|
||
|
|
|
||
|
|
Let Metro Bundler run in its _own_ terminal. Open a _new_ terminal from the _root_ of your React Native project. Run the following command to start your _Android_ or _iOS_ app:
|
||
|
|
|
||
|
|
### For Android
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# using npm
|
||
|
|
npm run android
|
||
|
|
|
||
|
|
# OR using Yarn
|
||
|
|
yarn android
|
||
|
|
```
|
||
|
|
|
||
|
|
### For iOS
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# using npm
|
||
|
|
npm run ios
|
||
|
|
|
||
|
|
# OR using Yarn
|
||
|
|
yarn ios
|
||
|
|
```
|
||
|
|
|
||
|
|
If everything is set up _correctly_, you should see your new app running in your _Android Emulator_ or _iOS Simulator_ shortly provided you have set up your emulator/simulator correctly.
|
||
|
|
|
||
|
|
This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.
|
||
|
|
|
||
|
|
## Step 3: Modifying your App
|
||
|
|
|
||
|
|
Now that you have successfully run the app, let's modify it.
|
||
|
|
|
||
|
|
1. Open `App.tsx` in your text editor of choice and edit some lines.
|
||
|
|
2. For **Android**: Press the <kbd>R</kbd> key twice or select **"Reload"** from the **Developer Menu** (<kbd>Ctrl</kbd> + <kbd>M</kbd> (on Window and Linux) or <kbd>Cmd ⌘</kbd> + <kbd>M</kbd> (on macOS)) to see your changes!
|
||
|
|
|
||
|
|
For **iOS**: Hit <kbd>Cmd ⌘</kbd> + <kbd>R</kbd> in your iOS Simulator to reload the app and see your changes!
|
||
|
|
|
||
|
|
## Congratulations! :tada:
