Render Menu from the backend

Render menu via backend

VITE(TS)

Mantis is already rendering the menu from the backend. The dashboard menus (Default, Analytics) are rendered via the back end.

You can check the Fack backend API here that we used to render the menu: https://github.com/phoenixcoded20/mock-data-api-nextjs

To add a menu from the backend, you can follow the steps below:

1. Open the file menu.ts (src/api/menu.ts), and edit the API URL in the useGetMenu function.

src/api/menu.ts

...

import { fetcher } from 'utils/axios';

// types
import { MenuProps, NavItemType } from 'types/menu';

export const endpoints = {
  key: 'api/menu',
  dashboard: '/dashboard' // server URL
};

...

export function useGetMenu() {
  const { data, isLoading, error, isValidating } = useSWR(endpoints.key + endpoints.dashboard, fetcher, {
    revalidateIfStale: false,
    revalidateOnFocus: false,
    revalidateOnReconnect: false
  });

  const memoizedValue = useMemo(() => {
    let updatedMenu = data?.dashboard;

    if (updatedMenu && Array.isArray(updatedMenu.children) && updatedMenu.children.length > 0) {
      updatedMenu = {
        ...updatedMenu,
        children: updatedMenu.children.map((group: NavItemType) => {
          if (Array.isArray(group.children)) {
            return {
              ...group,
              children: [...group.children, staticMenuItem]
            };
          }
          return group;
        })
      };
    }

    return {
      menu: updatedMenu as NavItemType,
      menuLoading: isLoading,
      menuError: error,
      menuValidating: isValidating,
      menuEmpty: !isLoading && !data?.length
    };
  }, [data, error, isLoading, isValidating]);

  return memoizedValue;
}
...

1. Create Menu File

   1. Add file menu.tsx in src/menu-items, and copy code from dashboard.tsx (src/menu-items/). Set icons and local files according to the API response.

2. Open the file index.tsx (src/layout/Dashboard/Drawer/DrawerContent/Navigation/index.tsx), and add the below code of the line.

src/layout/Dashboard/Drawer/DrawerContent/Navigation/index.tsx

import { useLayoutEffect, useState } from 'react'
...

import menuItem from 'menu-items';
import { MenuFromAPI } from 'menu-items/menu';
import { useGetMenu, useGetMenuMaster } from 'api/menu';
...

// ==============================|| DRAWER CONTENT - NAVIGATION ||============================== //

export default function Navigation() {

...
const { menuLoading } = useGetMenu();
...
const [menuItems, setMenuItems] = useState<{ items: NavItemType[] }>({ items: [] });

let dashboardMenu = MenuFromAPI();

useLayoutEffect(() => {
    const isFound = menuItem.items.some((element) => {
      if (element.id === 'group-dashboard') {
        return true;
      }
      return false;
    });

    if (menuLoading) {
      menuItem.items.splice(0, 0, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else if (!menuLoading && dashboardMenu?.id !== undefined && !isFound) {
      menuItem.items.splice(0, 1, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else {
      setMenuItems({ items: [...menuItem.items] });
    }
    // eslint-disable-next-line
  }, [menuLoading]);
