  • Last Updated : 10 Jul, 2021

BlueprintJS is a React-based UI toolkit for the web. This library is very optimized and popular for building interfaces that are complex data-dense for desktop applications. ResizeSensor2 Component provides a way for users to provides them a resize event for its single DOM element child. We can use the following approach in ReactJS to use the ReactJS Blueprint ResizeSensor2 Component.

ResizeSensor2 Props:

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

  • children: It is used to denote a single child, and it must be an element and not a string or fragment.
  • observeParents: It is used to indicate that all parent DOM elements of the container will also be observed for size changes if this is set to true.
  • onResize: It is a callback that is triggered when the wrapped element resizes.
  • targetRef: If we want to attach a ref to the child yourself when rendering it, you must pass the same value here.

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 @blueprintjs/core
    npm install @blueprintjs/popover2

Project Structure: It will look like the following.

function App() {
    return (
        <div style={{
            display: 'block', width: 400, padding: 30
            <h4>ReactJS Blueprint ResizeSensor2 Component</h4>
            <ResizeSensor2 onResize={(entries) =>
                e =>`${e.contentRect.width} x ${e.contentRect.height}`))}>
                <div style={{ width: 400, backgroundColor: 'lightgrey'
                height: 100 }}>
                    Component Dimesion: 400 X 100
        </div >
export default App;
