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 [Set Up Your Environment](https://reactnative.dev/docs/set-up-your-environment) guide before proceeding.
|
||
|
||
## Step 1: Start Metro
|
||
|
||
First, you will need to run **Metro**, the JavaScript build tool for React Native.
|
||
|
||
To start the Metro dev server, run the following command from the root of your React Native project:
|
||
|
||
```sh
|
||
# Using npm
|
||
npm start
|
||
|
||
# OR using Yarn
|
||
yarn start
|
||
```
|
||
|
||
## Step 2: Build and run your app
|
||
|
||
With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:
|
||
|
||
### Android
|
||
|
||
```sh
|
||
# Using npm
|
||
npm run android
|
||
|
||
# OR using Yarn
|
||
yarn android
|
||
```
|
||
|
||
### iOS
|
||
|
||
For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).
|
||
|
||
The first time you create a new project, run the Ruby bundler to install CocoaPods itself:
|
||
|
||
```sh
|
||
bundle install
|
||
```
|
||
|
||
Then, and every time you update your native dependencies, run:
|
||
|
||
```sh
|
||
bundle exec pod install
|
||
```
|
||
|
||
For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).
|
||
|
||
```sh
|
||
# Using npm
|
||
npm run ios
|
||
|
||
# OR using Yarn
|
||
yarn ios
|
||
```
|
||
|
||
If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.
|
||
|
||
This is one way to run your app — you can also build it directly from Android Studio or Xcode.
|
||
|
||
## Step 3: Modify your app
|
||
|
||
Now that you have successfully run the app, let's make changes!
|
||
|
||
Open `App.tsx` in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by [Fast Refresh](https://reactnative.dev/docs/fast-refresh).
|
||
|
||
When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload:
|
||
|
||
- **Android**: Press the <kbd>R</kbd> key twice or select **"Reload"** from the **Dev Menu**, accessed via <kbd>Ctrl</kbd> + <kbd>M</kbd> (Windows/Linux) or <kbd>Cmd ⌘</kbd> + <kbd>M</kbd> (macOS).
|
||
- **iOS**: Press <kbd>R</kbd> in iOS Simulator.
|
||
|
||
## Congratulations! :tada:
|
||
|
||
You've successfully run and modified your React Native App. :partying_face:
