@arco-design/mobile-react v2.33.0

Quick Start

Follow the steps below to quickly get started using the component library.

========

Installation

npm install @arco-design/mobile-react -S

Project Dependencies

"peerDependencies": {
    "react": ">=16.9.0",
    "react-dom": ">=16.9.0",
    "react-transition-group": ">=4.3.0"
}

Self-adaptation

The style uses rem for self-adaptation (@base-font-size: 50px). Please make sure that the project has introduced flexible.js or other tool functions that can set the basic font size for html according to the screen size. You can also import flexible.js provided in this component library:

import setRootPixel from '@arco-design/mobile-react/tools/flexible';

setRootPixel();

If the baseFontSize is different, you can change the incoming parameters and change the @base-font-size variable:

// js
/**
 * @param baseFontSize Baseline fontSize of 1rem, default 50
 * @param sketchWidth Width of UI draft, default 375
 * @param maxFontSize Maximum fontSize limit, default 64
 * @return {() => void} removeRootPixel Cancel the baseFontSize setting and remove the resize listener
 */
setRootPixel(37.5);

// less options
lessOptions: {
    javascriptEnabled: true,
    modifyVars: {
        '@base-font-size': 37.5,
    }
}

Import with CDN

You can import CDN resources through the <script> tag. Note that you need to import the CDN resources of peerDependencies first.

React & ReactDOM: Click here

React Transition Group: Click here

<link ref="stylesheet" href="https://unpkg.com/@arco-design/mobile-react@2.32.0/dist/style.min.css">
<script src="https://unpkg.com/@arco-design/mobile-react@2.32.0/dist/index.min.js"></script>

Full import

Note that style files need to be imported manually.

import Arco from '@arco-design/mobile-react';
import '@arco-design/mobile-react/esm/style';

Partial import (Recommended)

It is recommended to use babel-plugin-import to import. (Click here to get more flexible configuration of this plugin):

npm install babel-plugin-import -D

Import components on demand

.babelrc.js:

plugins: [
    ["import", {
        "libraryName": "@arco-design/mobile-react",
        "libraryDirectory": "esm", // In SSR environment, you need to use `cjs` here
        "style": (path) => `${path}/style`,
    }]
]

Import icons on demand

.babelrc.js:

plugins: [
    ["import", {
        "libraryName": "@arco-design/mobile-react/esm/icon", // In SSR environment, you need to replace `esm` with `cjs`
        "libraryDirectory": "",
        "camel2DashComponentName": false,
    }]
]

If both component and Icon need to be imported on demand, you need to add a different name value to the third parameter.

plugins: [
    ["import", {
        "libraryName": "@arco-design/mobile-react",
        "libraryDirectory": "esm", // In SSR environment, you need to use `cjs` here
        "style": (path) => `${path}/style`
    }, "@arco-design/mobile-react"],
    ["import", {
        "libraryName": "@arco-design/mobile-react/esm/icon", // In SSR environment, you need to replace `esm` with `cjs`
        "libraryDirectory": "",
        "camel2DashComponentName": false
    }, "@arco-design/mobile-react/esm/icon"]
]

Then you only need to write one line when importing, and it will be loaded on demand instead of completely imported when packaging:

import { Button as ArcoButton } from '@arco-design/mobile-react';

import { IconAsk, IconBack } from '@arco-design/mobile-react/esm/icon';

Partial import（Vite）

It is recommended to use vite-plugin-importer to import（Click here to know more from this plugin）：

npm install vite-plugin-importer -D

Import components on demand

vite.config.ts ：

import usePluginImport from 'vite-plugin-importer'

export default defineConfig({
    plugins: [
        usePluginImport({
            libraryName: "@arco-design/mobile-react",
            libraryDirectory: "esm",
            style: (path) => `${path}/style`,
        })
    ]
})

Import icons on demand

vite.config.ts ：

import usePluginImport from 'vite-plugin-importer'

export default defineConfig({
    plugins: [
        usePluginImport({
            libraryName: "@arco-design/mobile-react/esm/icon",
            libraryDirectory: "",
            camel2DashComponentName: false,
        })
    ]
})

If both component and Icon need to be imported on demand, you just declare all and do not need any change.

vite.config.ts ：

import usePluginImport from 'vite-plugin-importer'

export default defineConfig({
    plugins: [
        usePluginImport({
            libraryName: "@arco-design/mobile-react",
            libraryDirectory: "esm",
            style: (path) => `${path}/style`,
        }),
        usePluginImport({
            libraryName: "@arco-design/mobile-react/esm/icon",
            libraryDirectory: "",
            camel2DashComponentName: false,
        })
    ]
})

Partial import (manual)

If you don't use babel-plugin-import, you need to import js and css files manually. The following example has the same effect as the import statement above:

import ArcoButton from '@arco-design/mobile-react/esm/button';
import '@arco-design/mobile-react/esm/button/style';

import IconAsk from '@arco-design/mobile-react/esm/icon/IconAsk';

Theme variable customization & dynamic switching

This component library uses less and css variables for theme customization. The css variable is mainly used for dynamic theme switching at runtime, and is disabled by default. If there is a need for dynamic theme switching, you can configure less options to enable the css variable:

lessOptions: {
    javascriptEnabled: true,
    modifyVars: {
        '@use-css-vars': 1, // Enable css variables
    }
},

Note that after configuring and enabling css variables, if there is less variable substitution, you need to replace the css variables at the same time:

// less options
lessOptions: {
    javascriptEnabled: true,
    modifyVars: {
        '@base-font-size': 37.5,
        '@primary-color': 'red',
    }
}

// css
:root {
    --base-font-size: 37.5;
    --primary-color: red;
}

Using components on PC

Only touch-related events are monitored and processed in the component. If you need to use the component on the PC side, you can import touch2mouse.js provided by this component library to be compatible with mouse event processing (Note: After importing this file, the following mouse events will be blocked: mousedown, mouseenter, mouseleave, mousemove, mouseout, mouseover and mouseup, and the page content cannot be selected):

import '@arco-design/mobile-react/tools/touch2mouse';
