Create a Card Component

First you need to import the components you want to use.

You can check out all available components in the Storybook. Take your time to play around a little, change some props and take a look at the coding.

1. For the sake of keeping the coding as short as possible, this tutorial will only use direct imports. Start with importing a Card component into your MyApp.jsx file (right below the existing import statement).

   import { Card } from "@ui5/webcomponents-react";
   

2. So, you imported the Card component. Now it’s time to use it. Replace the content of your <div> with a <Card>.

   In the Storybook, you can see that Cards can receive different props. For now only add heading='Card'.

   <div>
     <Card heading="Card"></Card>
   </div>
   

Your webpage should now look like this.

And the file like this:

import { Card } from "@ui5/webcomponents-react";

export function MyApp() {
  return (
    <div>
      <Card heading="Card"></Card>
    </div>
  );
}

The content area of the Card component is empty, this is because it didn’t receive any children. Children of Cards should be ReactNodes or an array of ReactNodes.

1. Add the following lines to your Card component:

   <Card heading="Card">
     <div>This is the content area of the Card</div>
   </Card>
   

2. Now the Card has a content area, but the font-family differs from the Card header. All UI5 Web Components for React components use the same styling, this includes font-family, color, etc.

   Replace with import statement to add another component Text to your MyApp.jsx file.

   import { Card, Text } from "@ui5/webcomponents-react";
   

   And replace the inner div with the Text component.

   <Card heading="Card">
     <Text>This is the content area of the Card</Text>
   </Card>
   

The font-family of the content now corresponds to the font-family of the header.

In this step, we will only apply inline-styling. You can also style your component using JSS, but this will be covered in Tutorial 6 of the tutorial series.

The Card now spreads across the whole screen, this behavior is intended so it takes up the whole space of its container.

1. To restrict the width of the Card, add the style prop.

   <Card heading="Card" style={{ width: "300px" }}>
     <Text>This is the content area of the Card</Text>
   </Card>
   

   

2. The content of the card is way too close to the border of the Card, so a padding is needed. UI5 Web Components comes with a Util library, which includes padding sizes.

   Execute this in your terminal:

   npm install @ui5/webcomponents-react-base --save
   

   Then import:

   import { spacing } from "@ui5/webcomponents-react-base";
   

   And finally add this to your Text component:

   <Text style={spacing.sapUiContentPadding}>
     This is the content area of the Card
   </Text>
   

   Hereby you get a standardized content-padding. spacing comes with many more properties, feel free to test them and see what they do.

After this step MyApp.jsx should look like this:

import React from "react";
import { Card, Text } from "@ui5/webcomponents-react";
import { spacing } from "@ui5/webcomponents-react-base";

export function MyApp() {
  return (
    <div>
      <Card heading="Card" style={{ width: "300px" }}>
        <Text style={spacing.sapUiContentPadding}>
          This is the content area of the Card
        </Text>
      </Card>
    </div>
  );
}

And your application like this:

1. The Card header can also be clickable. For this you need to set the headerInteractive prop to true.

   <Card heading="Card" style={{ width: "300px" }} headerInteractive>
   

   We didn’t pass a value to headerInteractive, because it defaults to true if the value is omitted.

2. To make the header react to a click, add a function as value to the onHeaderClick prop.

   <Card
     heading="Card"
     style={{ width: "300px" }}
     headerInteractive
     onHeaderClick={handleHeaderClick}
   >
   

3. Now, add the callback function right in the beginning of the component (definition function):

   export function MyApp() {
     const handleHeaderClick = () => {
       alert("Header clicked");
   };
   

The file now looks like this:

import React from "react";
import { Card, Text } from "@ui5/webcomponents-react";
import { spacing } from "@ui5/webcomponents-react-base";

export function MyApp() {
  const handleHeaderClick = () => {
    alert("Header clicked");
  };
  return (
    <div>
      <Card
        heading="Card"
        style={{ width: "300px" }}
        headerInteractive
        onHeaderClick={handleHeaderClick}
      >
        <Text style={spacing.sapUiContentPadding}>
          This is the content area of the Card
        </Text>
      </Card>
    </div>
  );
}

Now the header opens an alert box on click.
