How to Implement dynamic routing in routes.js for generated menu items in sidebar in universal react redux boilerplate by erikras

I am currently working on a CMS based project.

For which i am using the universal react redux boilerplate by erikras

I really need suggestions on handling dynamic routing

Lets take a simple scenario form the boilerplate...

In routes.js

<Route path="about" component={About}/>
<Route path="login" component={Login}/>
<Route path="survey" component={Survey}/>
<Route path="widgets" component={Widgets}/>

data.js

export const data = [
  {id: 1, property: 'Dashboard', link: '/'},
  {id: 2, property: 'Login', link: '/login'},
  {id: 3, property: 'About Us', link: '/About'},
];

now, let say on the basis of user role, the properties in json data will change

let say new property: is

{id: 4, property: 'test page', link: '/test'}

When react will render the components, how it would know the route link .. as it is not defined in the routes.js

I am not getting the right way to implement it

We need a sidebar made of specific menu content as per the user role .

Let say we are building a reservation system , there can be different user roles like admin, maintenance mode, assistant role .

So different role will have different properties, accordingly we need to generate the menu on the basis it, as the properties will definitely differ as per user role.

Answers

To handle dynamic routing based on user roles in a React application, you can follow these steps:

  1. Define Dynamic Routes: Use a configuration-based approach to define routes dynamically.

  2. Fetch or Define User Roles: Determine user roles and their corresponding routes.

  3. Generate Routes and Sidebar: Dynamically generate the routes and sidebar based on user roles.

Here’s a detailed approach:

Step 1: Define Dynamic Routes

Modify your routes.js to handle dynamic routes. You can create a function to generate routes based on user roles.

import React from 'react';
import { Route } from 'react-router-dom';
import About from './components/About';
import Login from './components/Login';
import Survey from './components/Survey';
import Widgets from './components/Widgets';
import TestPage from './components/TestPage'; // Assuming you have a TestPage component

const routeComponents = {
  About,
  Login,
  Survey,
  Widgets,
  TestPage
};

export const generateRoutes = (routes) => {
  return routes.map(({ link, component }) => {
    const Component = routeComponents[component];
    return <Route key={link} path={link} component={Component} />;
  });
};

Step 2: Fetch or Define User Roles and Routes

Define routes based on user roles. This can be done based on user data fetched from an API or from a configuration file.

// Define user role routes
const userRoleRoutes = {
  admin: [
    { link: '/about', component: 'About' },
    { link: '/login', component: 'Login' },
    { link: '/survey', component: 'Survey' },
    { link: '/widgets', component: 'Widgets' },
    { link: '/test', component: 'TestPage' }
  ],
  maintenance: [
    { link: '/login', component: 'Login' },
    { link: '/about', component: 'About' }
  ],
  assistant: [
    { link: '/survey', component: 'Survey' },
    { link: '/widgets', component: 'Widgets' }
  ]
};

// Function to get routes for a specific user role
const getRoutesForRole = (role) => {
  return userRoleRoutes[role] || [];
};

Step 3: Generate Routes and Sidebar

Generate the routes and sidebar dynamically based on the user role. Update your main app component or wherever you define the routes.

import React from 'react';
import { BrowserRouter as Router, Switch } from 'react-router-dom';
import { generateRoutes, getRoutesForRole } from './routes';

const App = () => {
  // Assume you get the user role from the user state or API
  const userRole = 'admin'; // Example: You can fetch this dynamically
  const routes = getRoutesForRole(userRole);

  return (
    <Router>
      <div>
        <Sidebar routes={routes} /> {/* Dynamic Sidebar */}
        <Switch>
          {generateRoutes(routes)}
        </Switch>
      </div>
    </Router>
  );
};

const Sidebar = ({ routes }) => (
  <ul>
    {routes.map(route => (
      <li key={route.link}>
        <a href={route.link}>{route.component}</a>
      </li>
    ))}
  </ul>
);

export default App;

Summary

  1. Define a mapping of components to their route paths.
  2. Fetch or define the user roles and their corresponding routes.
  3. Generate the routes and sidebar dynamically based on the user roles.

This way, you can handle dynamic routing and menu generation based on user roles in a flexible and scalable manner.
