To merge the child's menus into the parent's menu without hardcoding the routes, you can follow these steps:

1. Define an API or configuration file in both microfrontends to expose the menu data. This can be a simple JSON file or an API endpoint that returns the menu data.

2. In your parent application, retrieve the menu data from both microfrontends using the appropriate API or by importing the JSON files.

3. Merge the menu data from both microfrontends into a single menu structure. You can use JavaScript array manipulation methods like concat(), filter(), map(), or the spread operator (...) to achieve this.

Here's an example of how you can merge the menu data:

// Import menu data from both microfrontends
import microfrontend1Menu from 'microfrontend1/menu';
import microfrontend2Menu from 'microfrontend2/menu';

// Merge the menus
const mergedMenu = [...microfrontend1Menu, ...microfrontend2Menu];

// Render the merged menu in your parent application
<Menu>
  {mergedMenu.map((item) => (
    <MenuItem key={item.key} path={item.path}>
      {item.title}
    </MenuItem>
  ))}
</Menu>

By merging the menu data from both microfrontends, you can dynamically generate the parent menu in your application without hardcoding the routes. This allows you to easily add or remove menus from either microfrontend without having to make changes to the parent application.

Remember to adjust the code based on your specific project structure and requirements.

To merge the child's menus from two micro frontends into the parent's menu without hard coding the routes, you can use the ProLayout component from Ant Design Pro.

First, make sure each route in your configuration has a name field. This will be used by ProLayout to render the menu.

import { defineConfig } from "umi";

export default defineConfig({
  routes: [
-    { path: "/", component: "index" },
+    { path: "/", component: "index", name: "home" },
-    { path: "/docs", component: "docs" },
+    { path: "/docs", component: "docs", name: "docs" },
-    { path: "/products", component: "products" },
+    { path: "/products", component: "products", name: "products" },
  ],
  plugins: ["@umijs/plugins/dist/react-query"],
  reactQuery: {},
  npmClient: "pnpm",
});

Next, update the src/layouts/index.tsx file with the following code:

import { ProLayout } from '@ant-design/pro-layout';
import { Link, Outlet, useAppData, useLocation } from 'umi';

export default function Layout() {
  const { clientRoutes } = useAppData();
  const location = useLocation();
  return (
    <ProLayout
      route={clientRoutes[0]}
      location={location}
      title="Umi x Ant Design"
      menuItemRender={(menuItemProps, defaultDom) => {
        if (menuItemProps.isUrl || menuItemProps.children) {
          return defaultDom;
        }
        if (menuItemProps.path && location.pathname !== menuItemProps.path) {
          return (
            <Link to={menuItemProps.path} target={menuItemProps.target}>
              {defaultDom}
            </Link>
          );
        }
        return defaultDom;
      }}
    >
      <Outlet />
    </ProLayout>
  );
}

In this code, we use useAppData to retrieve the global client routes clientRoutes and pass clientRoutes[0] to ProLayout as the route prop. We also use useLocation() to get the current location information and pass it to ProLayout. Additionally, we customize the menuItemRender method to handle menu item click events and render the appropriate links.

Finally, you can delete the src/layouts/index.less file to keep your project files clean.

After making these changes, the menus from both micro frontends should appear merged in the parent's menu.
