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. NonIdealState Component provides a way for users to inform the user that some content is unavailable. There are three types of nonideal state : 

  • Empty state: To showcase an empty data UI. 
  • Loading state: To showcase that the data is loading for the website.
  • Error state: To denote a bug or error 404 on the website.

NonIdealState Props:

  • action: It is used to denote the action to resolve the non-ideal state which appears after the description.
  • children: It is used to pass the children component to the underlying element.
  • className: It is used to denote a space-delimited list of class names to pass along to a child element.
  • description: It is used to denote a longer description of the non-ideal state.
  • icon: It is used to denote the name of a Blueprint UI icon (or an icon element) to render before the text.
  • iconSize:  It is used to denote the size of a Blueprint UI icon.
  • layout: It is used to denote the layout (horizontal or vertical) for the non-ideal state.
  • title: It is used to denote the title for the non-ideal state.

Approach: Let us create a React project and install React Blueprint module. Then we will create a UI that will showcase React.js BluePrint Non-ideal state Component Props.

Creating React Project:

Step 1: To create a react app, you need to install react modules through npx command. “npx” is used instead of “npm” because you will be needing this command in your app’s lifecycle only once.

npx create-react-app project_name

Step 2: After creating your react project, move into the folder to perform different operations.

cd project_name

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

npm install @blueprintjs/core

Project Structure: After running the commands mentioned in the above steps, if you open the project in an editor you can see a similar project structure as shown below. The new component user makes or the code changes, we will be performing will be done in the source folder.

Project Structure

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

npm start

Example 1: We are creating a UI that shows React BluePrint Non-ideal State props denoting empty state.

App.js




import React from "react";
import "@blueprintjs/core/lib/css/blueprint.css";
import { NonIdealState, NonIdealStateIconSize } from "@blueprintjs/core";
export default function App() {
    return (
        <div style={{ margin: 100, textAlign: "center" }}>
            <h1 style={{ color: "green" }}>GeeksforGeeks</h1>
            <h3>React.js BluePrint Non-ideal state Component Props</h3>
            <br /><br />
            <NonIdealState
                icon={"search"}
                layout="horizontal"
                iconSize={NonIdealStateIconSize.SMALL}
                title="No course found."
                description='Please search another course. 
                Try searching other name.'
            />
        </div>
    );
}


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

 

Example 2: We are creating a UI that shows React BluePrint Non-ideal State props denoting loading state.

App.js




import React from "react";
import "@blueprintjs/core/lib/css/blueprint.css";
import { NonIdealState, NonIdealStateIconSize, Spinner } 
    from "@blueprintjs/core";
export default function App() {
    return (
        <div style={{ margin: 100, textAlign: "center" }}>
            <h1 style={{ color: "green" }}>GeeksforGeeks</h1>
            <h3>React.js BluePrint Non-ideal state Component Props</h3>
            <br /><br />
            <NonIdealState
                icon={<Spinner />}
                layout="vertical"
                iconSize={NonIdealStateIconSize.SMALL}
                title="Data is still loading"
                description='Please wait for few seconds...'
            />
        </div>
    );
}


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