How to Solve the if-else Issue in SCSS with React

When building interactive user interfaces, especially in frameworks like React, you may encounter hurdles related to styling that can baffle even experienced developers. A common frustration arises when trying to use if-else conditions in SCSS (Sass) to reflect changes in React's state. Today, we will delve into a situation faced by a developer who is trying to implement a toggle for a hamburger menu and figure out how to solve this problem step by step.

The Problem: Hamburger Menu Not Responding

In a recent project, a developer set out to create a hamburger menu that changes its appearance based on user interaction. The goal was to have the menu toggle open and closed when clicked. The developer utilized React and SCSS for styling. However, the menu remained perpetually in the "open" state, indicating a disconnect between the React component's state and the SCSS logic.

Developer's Attempt

Here's a glimpse of the developer's setup:

React Component:

Understanding the Problem

The core issue lies in the fact that SCSS does not understand JavaScript or React states. The $type variable is never dynamically updated based on the React component's state, which means the conditions (@ if $type == open) will not yield the expected output. Essentially, SCSS expects static values during the compilation, while the component is dynamically changing its state in runtime.

The Solution: Using CSS Classes for State Management

To effectively solve this problem, we can leverage CSS classes that toggle based on the state of the React component. Instead of trying to use SCSS's if-else for state management, we will introduce a new class that signifies whether the hamburger menu is open or closed.

Step-by-Step Fix

Add a Dynamic Class:
Update the burger div to include a new class is-open when the open state is true.

Update SCSS for Styling Changes:
Now, in your SCSS, you will define styles for when the hamburger menu has the is-open class.

Conclusion: React and SCSS Integration

By utilizing a toggleable class and properly structuring the SCSS styles, the interaction between React and SCSS can be seamlessly managed. The is-open class will reflect the open state of the hamburger menu and enable smooth transitions, solving the initial problem the developer faced.

With this solution, you can not only ensure that your menu behaves as expected but also keep your styling organized and maintainable. Armed with this knowledge, you'll be better equipped to handle similar issues in the future!
