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. Breadcrumbs Component provides a way for users to identify the path to the current resource in an application. There are different ways to design Breadcrumb.

Breadcrumbs Props:

  • breadcrumbRenderer: It is a callback function that is triggered to render visible breadcrumbs.
  • className: It is used to denote a space-delimited list of class names to pass along to a child element.
  • collapseFrom: It is used to indicate which direction the breadcrumbs should collapse from i.e start or end.
  • currentBreadcrumbRenderer: It is a callback function that is triggered to render the current breadcrumb.
  • items: It is used to denote all breadcrumbs to display.
  • minVisibleItems: It is used to denote the minimum number of visible breadcrumbs that should never collapse into the overflow menu.
  • overflowListProps: It is used to denote props to spread to OverflowList.
  • popoverProps: It is used to denote props to spread to the Popover showing the overflow menu.

Approach: Let us create a React project and install React Blueprint module. Then we will create a UI that will showcase React.js BluePrint Breadcrumbs Component Breadcrumbs Prop,

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 different Breadcrumbs Component Breadcrumbs Props.

App.js




import React from 'react'
import '@blueprintjs/core/lib/css/blueprint.css';
import { Breadcrumbs } from "@blueprintjs/core";
  
function App() {
  
    const sampleItems = [
        { href: "/path 1", text: "Path 1" },
        { href: "/path 2", text: "Path 2" },
        { href: "/path 3", text: "Path 3" },
        { href: "/path 4", text: "Path 4" },
        { href: "/path 5", text: "Path 5" }
    ];
    return (
        <div style={{ margin: 100 }}>
            <h1 style={{ color: 'green' }}>
                GeeksforGeeks
            </h1>
            <h3>
                React.js BluePrint Breadcrumbs 
                Component Breadcrumbs Prop
            </h3>
            <br />
            <div style={{ width: 180 }}>
                <p>Collapse from start</p><br />
                <Breadcrumbs collapseFrom="start"
                    items={sampleItems} /><br />
                <p>Collapse from end</p><br />
                <Breadcrumbs collapseFrom="end"
                    items={sampleItems} />
            </div>
        </div >
    );
}
  
export default App;


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 Breadcrumbs Component Breadcrumbs Props.

App.js




import React from 'react'
import '@blueprintjs/core/lib/css/blueprint.css';
import { Breadcrumbs } from "@blueprintjs/core";
  
export default function App() {
  
    const sampleItems = [
        { href: "/path 1", text: "Path 1" },
        { href: "/path 2", text: "Path 2" },
        { href: "/path 3", text: "Path 3" },
        { href: "/path 4", text: "Path 4" },
        { href: "/path 5", text: "Path 5" }
    ];
    return (
        <div style={{ margin: 100 }}>
            <h1 style={{ color: 'green' }}>
                GeeksforGeeks
            </h1>
            <h3>
                React.js BluePrint Breadcrumbs 
                Component Breadcrumbs Prop
            </h3>
            <br />
  
            <p>
                Collapse from start. 
                Minimumn Visible items - 3
            </p><br />
  
            <div style={{ width: 200 }}>
                <Breadcrumbs items={sampleItems}
                    minVisibleItems={3} /><br />
            </div>
              
            <p>
                Collapse from end. Minimumn 
                Visible items - 2
            </p><br />
              
            <div style={{ width: 200 }}>
                <Breadcrumbs style={{ width: 200 }}
                    collapseFrom="end" 
                    items={sampleItems} 
                    minVisibleItems={2} />
            </div>
        </div >
    );
}


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