How to Apply Layout to Component Conditionally in React

React is a powerful library for creating dynamic user interfaces, but as you navigate its complexities, you may encounter situations where you need to apply layouts conditionally based on specific criteria, like user authentication. If you’re new to React and are struggling with this concept, you’re not alone! In this post, we will break down the approach you can take to achieve this and help you seamlessly use different layouts depending on whether a user is authenticated or not.

Understanding the Problem

Imagine you have several pages in your React application that should look different depending on whether a user is logged in (authenticated) or not. You may have two layouts: one for logged-in users (Layout1) and another for visitors who have yet to log in (Layout2). The challenge here is to determine which layout to use based on the user's authentication status.

The Key Challenge

One key challenge is that you cannot access the isAuthenticated variable outside of your component. This makes defining the layout conditionally quite tricky. However, fear not! There’s a straightforward way to tackle this issue.

Step-by-Step Solution

To accomplish the task of applying layouts conditionally, we will create separate components for the authenticated and non-authenticated states. Let’s break it down into manageable steps.

Step 1: Create the Authenticated Component

First, we need a component that represents an authenticated user. We will define this component with its layout.

Step 2: Create the Non-Authenticated Component

Next, we’ll create a component for users who are not authenticated and set its layout accordingly.

Step 3: Create the Main Page Component

Finally, we’ll create the main page component (MyPage.ts) which will determine which child component to render based on the user's authentication status.

Explanation of the Code

Logged Component: Returns a message for logged-in users, and specifies its layout as Layout1.

NotLogged Component: Displays a message prompting the user to log in, with Layout2 as its layout.

MyPage Component: This is where the authentication check occurs. It uses the useAuth hook to determine whether the user is authenticated and renders the appropriate component.

Conclusion

By following this structured approach, you can conditionally apply layouts to your components in React based on authentication status. This not only helps to maintain clean code but enhances the user experience by providing the appropriate visibility based on user states.

Feel free to adapt this pattern as necessary for more complex authentication logic or layout structures in your React applications! If you have any questions or need assistance with your own implementations, don't hesitate to reach out.
