In this tutorial, you will learn how to create routes to different paths of your application. For this you will create a new page and set up routing between the page and the dashboard.

Step 1
In src create a Detail.jsx file.
Inside of that file, create the Detail component that will return a title to your liking.
JavaScript / JSX
Copy
import React from "react"; import { Title } from "@ui5/webcomponents-react"; export function Detail() { return <Title>Hello World!</Title>; }
Step 2
Install react-router-dom.

React Router is a collection of navigational components that compose declaratively with your application.

Execute the following line in the terminal in your root location of the project.

Shell
Copy
npm install react-router-dom --save

Import HashRouter in src/App.js.

JavaScript / JSX
Copy
import { HashRouter } from "react-router-dom";

And wrap your root component inside of it:

JavaScript / JSX
Copy
<HashRouter> <ThemeProvider> <MyApp /> </ThemeProvider> </HashRouter>
You can replace your div with the HashRouter as the HashRouter also functions as container.

Step 3

In src, create a new Home.jsx file.

For now only create a Home component that returns null.

JavaScript / JSX
Copy
```
import React from "react";

export function Home() {
  return null;
}
```

Refactor MyApp.jsx.

Some refactoring is necessary now. Extract every component and the corresponding logic except for the ShellBar from MyApp.jsx and move it to Home.jsx.

MyApp.jsx should now look like this:

JavaScript / JSX

Copy

import React from "react";
import { Avatar, ShellBar, ShellBarItem } from "@ui5/webcomponents-react";
import "@ui5/webcomponents-icons/dist/add.js";

export function MyApp() {
  return (
    <div>
      <ShellBar
        logo={<img src="reactLogo.png" />}
        profile={
          <Avatar>
            <img src="profilePictureExample.png" />
          </Avatar>
        }
        primaryTitle="My App"
      >
        <ShellBarItem icon="add" text="Add" />
      </ShellBar>
    </div>
  );
}

And Home.jsx like this:

JavaScript / JSX

Copy

import React, { useState } from "react";
import {
  AnalyticalTable,
  Card,
  CardHeader,
  FlexBox,
  FlexBoxDirection,
  FlexBoxJustifyContent,
  FlexBoxWrap,

  List,
  ProgressIndicator,
  StandardListItem,
  Text,
  Title,
  TitleLevel,
  ValueState
} from "@ui5/webcomponents-react";
import { spacing } from "@ui5/webcomponents-react-base";
import { BarChart, LineChart } from "@ui5/webcomponents-react-charts";
import "@ui5/webcomponents-icons/dist/line-chart.js";
import "@ui5/webcomponents-icons/dist/horizontal-bar-chart.js";
import "@ui5/webcomponents-icons/dist/list.js";
import "@ui5/webcomponents-icons/dist/table-view.js";

    data: 40
  }
];

const tableData = new Array(500).fill(null).map((_, index) => {
  return {
    name: `name${index}`,
    age: Math.floor(Math.random() * 100),
    friend: {
      name: `friend.Name${index}`,
      age: Math.floor(Math.random() * 100)
    }
  };
});

const tableColumns = [
  {
    Header: "Name",
    accessor: "name" // String-based value accessors!
  },
  {
    Header: "Age",
    accessor: "age"
  },
  {
    Header: "Friend Name",
    accessor: "friend.name"
  },
  {
    Header: "Friend Age",
    accessor: "friend.age"
  }
];

export function Home() {
  const [toggleCharts, setToggleCharts] = useState("lineChart");
  const [loading, setLoading] = useState(false);

      }, 2000);
    } else {
      setLoading(true);
      setTimeout(() => {

        setToggleCharts("lineChart");
      }, 2000);
    }
  };

            >
              <FlexBox direction={FlexBoxDirection.Column}>
                <Title level={TitleLevel.H5}>Activity 4</Title>

          </List>
        </Card>
        <Card
          header={
            <CardHeader
              titleText="AnalyticalTable"
              avatar={<Icon name="table-view" />}
            />
          }
          style={{ maxWidth: "900px", ...spacing.sapUiContentPadding }}
        >
          <AnalyticalTable
            data={tableData}
            columns={tableColumns}
            visibleRows={5}
          />
        </Card>
      </FlexBox>
    </div>
  );
}

Step 4

In MyApp.jsx, import Routes, Route and Navigate from react-router-dom and the Home and Detail components.

JavaScript / JSX

Copy

import { Routes, Route, Navigate } from "react-router-dom";
import { Home } from "./Home";
import { Detail } from "./Detail";

Wrap your ShellBar component inside of Fragments and set up paths with Routes and the component (element) displayed respectively.

JavaScript / JSX

Copy

return (
  <>
    <ShellBar
      logo={<img src="reactLogo.png" />}
      profile={
        <Avatar>
          <img src="profilePictureExample.png" />
        </Avatar>
      }
      primaryTitle="My App"
    >
      <ShellBarItem icon="add" text="Add" />
    </ShellBar>
    <Routes>
      <Route path="/home" element={<Home />} />
      <Route path="/detail" element={<Detail />} />
      <Route path="/" element={<Navigate replace to="/home" />} />
    </Routes>
  </>
);

The Navigate component will redirect the user if the URL doesn’t match any given paths.

Your current URL now displays the #/home path. If you replace home with detail, you will be routed to the detail page.

Step 5
Except for changing the URL of the App the user doesn’t have options to navigate to the Detail page. The page could contain some more information about activities and should therefore be connected to the Progress Card.

Go into your Home component and add interactive and onClick={handleProgressHeaderClick} to your second CardHeader component.

JavaScript / JSX
Copy
<Card header={ <CardHeader titleText="Progress" subtitleText="List" avatar={<Icon name="list" />} interactive onClick={handleProgressHeaderClick} /> } style={{ width: "300px", ...spacing.sapUiContentPadding }} >

Define the handleProgressHeaderClick function as follows. And import the useNavigate hook from react-router-dom.

JavaScript / JSX
Copy
import { useNavigate } from "react-router-dom";

JavaScript / JSX
Copy
const navigate = useNavigate(); const handleProgressHeaderClick = () => { navigate("/detail"); };

Now it is possible to navigate to the Details component, but right now, there is no way to go back except for the back button of the browser and typing in the URL manually.

Navigate back to the Home Screen

Normally when you click on the Logo of the app, it should send you back to your Home screen. Let’s implement that.

Go into your MyApp.jsx file where your ShellBar is located and add an onLogoClick prop. The function is almost the same as for the onHeaderClick, but this time the destination should be the default page.

JavaScript / JSX
Copy
const navigate = useNavigate(); const handleLogoClick = () => { navigate("./"); };

JavaScript / JSX
Copy
<ShellBar logo={<img src="reactLogo.png" />} profile={<Avatar image="profilePictureExample.png" />} primaryTitle="My App" onLogoClick={handleLogoClick} >

What is the functionality of the Navigate component of react-router-dom in this project?
It will redirect the user to the previously visited site.
It will redirect the user to the Homepage if no matching path is passed.
It will close the page if the user didn't move the cursor for more than five minutes.
It will redirect the page to a different port.

Step 6

If needed, you can compare your files with the following code references:

MyApp.jsx:

JavaScript / JSX

Copy

import React from "react";
import { Avatar, ShellBar, ShellBarItem } from "@ui5/webcomponents-react";
import "@ui5/webcomponents-icons/dist/add.js";
import { Routes, Route, Navigate } from "react-router-dom";
import { useNavigate } from "react-router-dom";
import { Home } from "./Home";
import { Detail } from "./Detail";

export function MyApp() {
  const navigate = useNavigate();
  const handleLogoClick = () => {
    navigate("./");
  };
  return (
    <>
      <ShellBar
        logo={<img src="reactLogo.png" />}
        profile={
          <Avatar>
            <img src="profilePictureExample.png" />
          </Avatar>
        }
        primaryTitle="My App"
        onLogoClick={handleLogoClick}
      >
        <ShellBarItem icon="add" text="Add" />
      </ShellBar>
      <Routes>
        <Route path="/home" element={<Home />} />
        <Route path="/detail" element={<Detail />} />
        <Route path="/" element={<Navigate replace to="/home" />} />
