Text Field Validations

In this application, we have implemented validations for each text field to ensure data integrity and improve user experience. Below are the details of the validations for each field:

Name Field

• Requirement: Mandatory
• Validation Criteria:
  • Cannot be empty or contain only spaces.
  • Allows only alphabets and single spaces between words.

Age Field

• Requirement: Mandatory
• Validation Criteria:
  • Must be a two-digit number.
  • Should be between the age range of 10 to 99.

Email Field

• Requirement: Mandatory
• Validation Criteria:
  • Must be a valid email address format.

These validations help maintain the quality of data and provide users with clear guidelines for input.

Installation

1. Clone the repository:

   git clone https://github.com/amoltdhage/ReactNative-DynamicPostAPIDemo.git
   
   

This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

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:

# 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

# using npm
npm run android

# OR using Yarn
yarn android

For iOS

# 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 R key twice or select "Reload" from the Developer Menu (Ctrl + M (on Window and Linux) or Cmd ⌘ + M (on macOS)) to see your changes!

   For iOS: Hit Cmd ⌘ + R in your iOS Simulator to reload the app and see your changes!

Congratulations! 🎉

You've successfully run and modified your React Native App. 🥳
