It has been nearly two years since the first version of v4. During this time, more than 30 versions of v4 have been iterated and many new features have been added. More and more developers are starting to use React Suite and participating in function development and improvement. And the developers who have been making valuable suggestions to us, we thank you again. I hope React Suite can accompany your product to continue to grow, and also hope to serve more developers.

The accessibility and scalability of components are improved in React Suite 5. The following will introduce in detail the new features and how to upgrade from 4.x to 5.0.

Major changes ✨

Improve accessibility

It is our hope that more users can use barrier-free use of products developed by React Suite. We will improve each component provided by React Suite in multiple scenarios such as keyboard operation and screen reading devices.

Accessibility

React Suite follows the WAI-ARIA standard. All components have been refactored to have appropriate attributes and keyboard interaction functions out of the box.

Add a set of high contrast themes

In React Suite v4, we refer to the 《Web Content Accessibility Guidelines (WCAG) 》 standard for color contrast requirements, and have made great improvements to the components to meet most users. We still hope to improve on this basis and take care of a small number of people with visual impairments. React Suite officially provides a total of 3 sets of themes (light, dark, high-contrast).

Use SVG Icon instead of Icon font

Icon font has some rendering problems, which makes the icon blurry, the need to load the font file, and the content area flickers. For better accessibility, we decided to prefer SVG Icon. And can be well compatible with third-party icon resources.

import GearIcon from "@rsuite/icons/Gear";render(<GearIcon />);// output
<svg>
  <path d="M11.967 ..."></path>
  <path d="M8 10a2 2 0 10.001-3.999A2 2 0 008 10zm0 1a3 3 0 110-6 3 3 0 010 6z"></path>
</svg>;

Support CSS variables

Current mainstream browsers already support CSS variables. We plan to provide a set of component CSS variable configurations to make theme customization and theme switching more convenient.

Refactoring React Class Components with Hooks

We refactored most of our components using function component and adopted the new features brought by React Hooks to enhance the development experience.

Import on Demand

When importing components in v4, you need to distinguish between cjs and esm. In v5 this is automatic.

// v4: cjs
import Button from "rsuite/lib/Button";
// v4: esm
import Button from "rsuite/es/Button";// v5
import Button from "rsuite/Button";

Improvements to Form

• Improve the style of Form in plain text mode
• Rename Form related components

Rename FormGroup to Form.Group
Rename FormControl to Form.Control
Rename ControlLabel to Form.ControlLabel
Rename ErrorMessage to Form.ErrorMessage
Rename HelpBlock to Form.HelpText

• Form validation supports object structure

const model = SchemaModel({
  username: StringType().isRequired("Username required"),
  tags: ArrayType().of(StringType("The tag should be a string").isRequired()),
  role: ObjectType.shape({
    name: StringType().isRequired("Name required"),
    permissions: ArrayType().isRequired("Permissions required"),
  }),
});const checkResult = model.check({
  username: "foobar",
  tags: ["Sports", "Games", 10],
  role: { name: "administrator" },
});console.log(checkResult);

output:

{
  username: { hasError: false },
  tags: {
    hasError: true,
    array: [
      { hasError: false },
      { hasError: false },
      { hasError: true, errorMessage: 'The tag should be a string' }
    ]
  },
  role: {
    hasError: true,
    object: {
      name: { hasError: false },
      permissions: { hasError: true, errorMessage: 'Permissions required' }
    }
  }
};

Added support for srcSet, sizes,imgProps on Avatar

• srcSet: The srcSet attribute for the img element. Use this attribute for responsive image display.
• sizes: The sizes attribute for the img element.
• imgProps: Attributes applied to the img element if the component is used to display an image.

Added support onChangeCommitted on Slider and RangeSlider

The difference between onChangeCommitted and onChange is that onChange is triggered every time the value changes, while onChangeCommitted is a callback that is triggered after the mouseup event is triggered and the value changes.

Improvements to DatePicker and DateRangePicker

• DatePicker and DateRangePicker support keyboard input.

• DateRangePicker can only select date before, and time can be selected in v5

<DateRangePicker format="yyyy-MM-dd HH:mm:ss" />

Add support for color on Badge

<Badge color="red">Red</Badge>
<Badge color="orange">Orange</Badge>
<Badge color="yellow">Yellow</Badge>

Improvements to Table

• Refactor Table

Use react hooks to refactor the Table and improve the performance when the table scrolls. The onDataUpdated and bodyRef props are deprecated.

For some components to be rendered inside the table, the body container of the table can be obtained through bodyRef before. Now we can get the container directly through the ref of Table.

// v4
const bodyRef = useRef();
return (
  <>
    <Table
      bodyRef={(body) => {
        bodyRef.current = body;
      }}
    />
    <CheckPicker container={() => bodyRef.current} />
  </>
);// v5
const ref = useRef();
return (
  <>
    <Table ref={ref} />
    <CheckPicker container={() => ref.current.body} />
  </>
);

• Add support for rowSpan

const data = [
  {
    city: "New Gust",
    name: "Janis",
    rowspan: 2,
  },
  {
    city: "New Gust",
    name: "Ernest Schuppe Anderson",
  },
  {
    city: "Maria Junctions",
    name: "Alessandra",
    rowspan: 3,
  },
  {
    city: "Maria Junctions",
    name: "Margret",
  },
  {
    city: "Maria Junctions",
    name: "Emiliano",
  },
];
return (
  <Table data={data}>
    <Column
      width={100}
      verticalAlign="middle"
      rowSpan={(rowData) => {
        return rowData.rowspan;
      }}
    >
      <HeaderCell>Name</HeaderCell>
      <Cell dataKey="city" />
    </Column>
    <Column width={100}>
      <HeaderCell />
      <Cell dataKey="name" />
    </Column>
  </Table>
);

Add support for TagInput

The enhancement of Input supports input tags and management tags.

import TagInput from "rsuite/TagInput";return (
  <TagInput
    defaultValue={["HTML", "CSS"]}
    trigger={["Enter", "Space", "Comma"]}
  />
);

Improvements to Carousel

Support onSelect, onSlideEnd, onSlideStart on <Carousel>

• onSelect: Callback fired when the active item changes
• onSlideEnd: Callback fired when a slide transition ends
• onSlideStart: Callback fired when a slide transition starts
