Installation

Getting started with Semi-UI is straightforward. You can install it using npm or yarn:

npm install @douyinfe/semi-ui

or

yarn add @douyinfe/semi-ui

Basic Usage

Let’s dive into a simple example to demonstrate how easy it is to use Semi-UI components:

import React from 'react';
import { Button, Form } from '@douyinfe/semi-ui';

const App: React.FC = () => {
  return (
    <Form>
      <Form.Input field='name' initValue='Semi Design' />
      <Button htmlType='submit'>Submit</Button>
    </Form>
  );
};

export default App;

In this example, we’ve created a simple form with an input field and a submit button. The Form component handles form state and submission, while the Form.Input and Button components provide the user interface elements.

Advanced Usage

Theming and Customization

One of Semi-UI’s strengths is its flexibility in theming. You can easily customize the look and feel of your application:

import { ConfigProvider } from '@douyinfe/semi-ui';

const customTheme = {
  colors: {
    primary: '#6a1b9a',
    secondary: '#00838f',
  },
};

const App: React.FC = () => {
  return (
    <ConfigProvider theme={customTheme}>
      {/* Your app components */}
    </ConfigProvider>
  );
};

This example demonstrates how to use the ConfigProvider to apply a custom theme to your entire application. The customTheme object allows you to override default color values and other design tokens.

Responsive Design

Semi-UI components are built with responsiveness in mind. Let’s look at how we can create a responsive layout using the Grid system:

import { Row, Col } from '@douyinfe/semi-ui';

const ResponsiveLayout: React.FC = () => {
  return (
    <Row>
      <Col xs={24} sm={12} md={8} lg={6}>
        <div>Column 1</div>
      </Col>
      <Col xs={24} sm={12} md={8} lg={6}>
        <div>Column 2</div>
      </Col>
      <Col xs={24} sm={12} md={8} lg={6}>
        <div>Column 3</div>
      </Col>
      <Col xs={24} sm={12} md={8} lg={6}>
        <div>Column 4</div>
      </Col>
    </Row>
  );
};

This layout will adjust based on the screen size, with columns stacking on smaller screens and expanding on larger ones.

Internationalization

Semi-UI makes it easy to create multilingual applications. Here’s how you can set up internationalization:

import { LocaleProvider } from '@douyinfe/semi-ui';
import en_US from '@douyinfe/semi-ui/lib/es/locale/source/en_US';

const App: React.FC = () => {
  return (
    <LocaleProvider locale={en_US}>
      {/* Your app components */}
    </LocaleProvider>
  );
};

By wrapping your app with LocaleProvider, you can easily switch between different language packs.
