Icon upgrade#

In antd @ 3.9.0, we introduced the svg icon (Why use the svg icon?). The icon API using the string name cannot be loaded on demand, so the svg icon file is fully introduced, which greatly increases the size of the packaged product. In 4.0, we adjusted the icon usage API to support tree shaking, reducing the default package size of antd by about 150 KB (Gzipped).

Legacy Icon usage will be discarded:

import { Icon, Button } from 'antd';

const Demo = () => (
    <Icon type="smile" />
    <Button icon="smile" />

It will be imported on demand in v4:

  import { Button } from 'antd';

  // tree-shaking supported
- import { Icon } from 'antd';
+ import { SmileOutlined } from '@ant-design/icons';

  const Demo = () => (
-       <Icon type="smile" />
+       <SmileOutlined />
      <Button icon={<SmileOutlined />} />

  // or directly import
  import SmileOutlined from '@ant-design/icons/SmileOutlined';

You will still be able to continue using the compatibility pack:

import { Button } from 'antd';
import { Icon } from '@ant-design/compatible';

const Demo = () => (
    <Icon type="smile" />
    <Button icon="smile" />

Component refactoring#

  • Form rewrite.

    • No need to use Form.create.

    • Nest fields definition changes from 'xxx.yyy' to ['xxx', 'yyy'].

    • validateTrigger no long collect field value.

    • See here for migration documentation.

  • DatePicker rewrite

    • Provide the picker property for selector switching.

    • Range selection can now select start and end times individually.

    • onPanelChange will also trigger when panel value changed.

    • Date cell className of Custom style demo changed from ant-calendar-date to ant-picker-cell-inner.

  • Tree, Select, TreeSelect, AutoComplete rewrite

    • use virtual scrolling.

    • onBlur no longer trigger value change and return React origin event object instead.

      • If config validateTrigger as onBlur with compatible Form, please change to onChange instead.

    • AutoComplete no longer support optionLabelProp. Please set Option value directly.

    • AutoComplete options definition align with Select. Please use options instead of dataSource.

Start upgrading#

You can manually check the code one by one against the above list for modification. In addition, we also provide a codemod cli tool @ant-design/codemod-v4 To help you quickly upgrade to v4.

Before running codemod cli, please submit your local code changes.

# Run directly through npx
npx -p @ant-design/codemod-v4 antd4-codemod src

# Or global installation
# Use npm
npm i -g @ant-design/codemod-v4
# Use yarn
yarn global add @ant-design/codemod-v4

# Execute
antd4-codemod src

codemod running

For parts that cannot be modified automatically, codemod will prompt on the command line, and it is recommended to modify them manually as prompted. After modification, you can run the above command repeatedly to check.

contains an invalid icon

Note that codemod cannot cover all scenarios, and it is recommended to check for incompatible changes one by one.
