ReactJS UI Ant Design InputNumber Component

Ant Design Library has this component pre-built, and it is very easy to integrate as well. InputNumber Component allows the user to enter a number within a certain range with the help of a keyboard or mouse. We can use the following approach in ReactJS to use the Ant Design InputNumber Component.

Creating React Application And Installing Module:

• Step 1: Create a React application using the following command:

  npx create-react-app foldername

• Step 2: After creating your project folder i.e. foldername, move to it using the following command:

  cd foldername

• Step 3: After creating the ReactJS application, Install the required module using the following command:

  npm install antd

Project Structure: It will look like the following.

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
