Implementing Controlled Navigation in React

Enhance the security and user flow integrity in your React application by controlling navigation from a specified entry point. Follow these streamlined steps to setup managed navigation.

Step 1: Establishing Context for Navigation

Define a React Context to track whether navigation requests are internal or external.

import React, { useState, createContext } from 'react';

const NavigationContext = createContext();

export default NavigationContext;

</details>

Step 2: Setting Up the Provider

Initialize the navigation status to false within a Provider to treat each app load as an external navigation initially.

<details> <summary>View Code</summary>

export const NavigationProvider = ({ children }) => {
    const [isInternal, setIsInternal] = useState(false);

    return (
        <NavigationContext.Provider value={{ isInternal, setIsInternal }}>
            {children}
        </NavigationContext.Provider>
    );
};

</details>

Step 3: Integrating the Context Provider

Wrap your main App component with the NavigationProvider.

<details> <summary>View Code</summary>

import React from 'react';
import { NavigationProvider } from './NavigationContext';

const App = () => {
    return (
        <NavigationProvider>
            {/* Other components go here */}
        </NavigationProvider>
    );
};

export default App;

</details>

Step 4: Configuring Entry Point Detection

Mark navigation as internal using useEffect in your entry component.

<details> <summary>View Code</summary>

import React, { useContext, useEffect } from 'react';
import NavigationContext from './NavigationContext';

const EntryPointComponent = () => {
    const { setIsInternal } = useContext(NavigationContext);

    useEffect(() => {
        setIsInternal(true);
    }, []);

    return <div>Entry Point Content</div>;
};

</details>

Step 5: Creating a Protected Component

Conditionally render components based on the navigation status. Redirect if navigation is external.

<details> <summary>View Code</summary>

import React, { useContext } from 'react';
import { Navigate } from 'react-router-dom';
import NavigationContext from './NavigationContext';

const ProtectedComponent = ({ children }) => {
    const { isInternal } = useContext(NavigationContext);

    return isInternal ? children : <Navigate to="/login" replace />;
};

</details>

Test thoroughly and deploy confidently, knowing your navigation is securely managed.
