How to Retrieve SCSS Theme Colors in JavaScript with Svelte SMUI

In modern web development, using frameworks like Svelte along with component libraries such as SMUI (Svelte Material UI) can be a game-changing experience. However, you may run into some challenges, especially when it comes to managing theme colors. One common question that arises is: How can I get the color value of $primary from SCSS to JavaScript? Is it possible?

In this guide, we will walk through the solution to this problem, breaking it down into clear, actionable sections. Whether you're a seasoned developer or a beginner, you'll find helpful instructions on how to manage your theme colors effectively.

In this setup, you're expecting the $primary color to be accessible as a CSS variable, specifically --mdc-theme-primary. Unfortunately, it's not directly available in JavaScript, which raises the question of how we can retrieve that color value.

Solution Steps

To successfully get the SCSS theme color into JavaScript, we need to set the color as a CSS variable and then read it using JavaScript. Let’s break this down step-by-step.

Step 1: Define the CSS Variable in SCSS

First, you need to ensure that the SCSS variable is stored in a CSS variable. You can achieve this by making some changes to your SCSS code:
