import { Alert, Breadcrumb } from 'infrad';
import React from 'react';
import { HashRouter, Link, Route, Routes, useLocation } from 'react-router-dom';

const Apps = () => (
  <ul className="app-list">
    <li>
      <Link to="/apps/1">Application1</Link>：<Link to="/apps/1/detail">Detail</Link>

    </li>
  </ul>
);

const breadcrumbNameMap: Record<string, string> = {
  '/apps': 'Application List',
  '/apps/1': 'Application1',
  '/apps/2': 'Application2',
  '/apps/1/detail': 'Detail',
  '/apps/2/detail': 'Detail',
};

const Home = () => {
  const location = useLocation();
  const pathSnippets = location.pathname.split('/').filter(i => i);

  const extraBreadcrumbItems = pathSnippets.map((_, index) => {
    const url = `/${pathSnippets.slice(0, index + 1).join('/')}`;
    return (
      <Breadcrumb.Item key={url}>
        <Link to={url}>{breadcrumbNameMap[url]}</Link>
      </Breadcrumb.Item>
    );
  });

  const breadcrumbItems = [
    <Breadcrumb.Item key="home">
      <Link to="/">Home</Link>
    </Breadcrumb.Item>,
  ].concat(extraBreadcrumbItems);

  return (
    <div className="demo">
      <div className="demo-nav">
        <Link to="/">Home</Link>
        <Link to="/apps">Application List</Link>
      </div>
      <Routes>
        <Route path="/apps" element={<Apps />} />
        <Route path="*" element={<span>Home Page</span>} />
      </Routes>
      <Alert style={{ margin: '16px 0' }} message="Click the navigation above to switch:" />
      <Breadcrumb>{breadcrumbItems}</Breadcrumb>
    </div>
  );
};

const App: React.FC = () => (
  <HashRouter>
    <Home />
  </HashRouter>
);

export default App;
.demo {
  margin: 16px;
}
.demo-nav {
  height: 30px;
  margin-bottom: 16px;
  line-height: 30px;
  background: #f8f8f8;

const App: React.FC = () => (
  <Breadcrumb>
    <Breadcrumb.Item>Infra Design</Breadcrumb.Item>
    <Breadcrumb.Item>
      <a href="">Component</a>
    </Breadcrumb.Item>
    <Breadcrumb.Item overlay={menu}>

  <Breadcrumb>
    <Breadcrumb.Item href="">

    </Breadcrumb.Item>
    <Breadcrumb.Item href="">
      <UserOutlined />
      <span>Application List</span>

TypeScript
JavaScript
import { Breadcrumb } from 'infrad';
import React from 'react';

const App: React.FC = () => (
  <Breadcrumb separator=">">
    <Breadcrumb.Item>Home</Breadcrumb.Item>
    <Breadcrumb.Item href="">Application Center</Breadcrumb.Item>
    <Breadcrumb.Item href="">Application List</Breadcrumb.Item>
    <Breadcrumb.Item>An Application</Breadcrumb.Item>
  </Breadcrumb>
);

export default App;

Configuring the Separator

TypeScript
JavaScript
import { Breadcrumb } from 'infrad';
import React from 'react';

const App: React.FC = () => (
  <Breadcrumb separator="">
    <Breadcrumb.Item>Location</Breadcrumb.Item>
    <Breadcrumb.Separator>:</Breadcrumb.Separator>
    <Breadcrumb.Item href="">Application Center</Breadcrumb.Item>
    <Breadcrumb.Separator />
    <Breadcrumb.Item href="">Application List</Breadcrumb.Item>
