umi插件开发仿dumi项目自动生成导航栏实现详解

// /class="lazy" data-src/client/theme-api/useNavData.ts
import { useAppData } from "umi";

export const useNavData = () => {
  // 获取全局路由信息
  const { routes } = useAppData();
  // 获取/docs下的路由信息
  const localeDocRoutes: any[] = 
      Object.values(routes).filter(route => route.parentId === 'DocLayout')
  // 获取导航信息
  const nav: any = []
  Object.values(localeDocRoutes).forEach(route => {
    const _r = { ...route }
    if(_r.path == '/') {
      nav.push({
        title: '首页',
        link: '/',
      })
    } else {
      nav.push({
        title: route.path,
        link: '/' + route.path,
      })
    }
  })
  return nav;
};

// /class="lazy" data-src/client/theme-default/layouts/DocLayout.ts
import { Link, Outlet } from 'umi';
import { useNavData } from '@/client/theme-api/useNavData';
import styles from './index.less';
export default function Layout() {
  const nav = useNavData()
  return (
    <div className={styles.navs}>
      <ul>
          {nav.map((item: any) => (<li key={item.link}>
              <Link style={{ marginRight: '10px' }} to={item.link}>{item.title}</Link>
          </li>))}
      </ul>
      <Outlet />
    </div>
  );
}
