Dynamically Render SVG Icons in React with TypeScript: A Step-by-Step Guide

SVG icons are a popular choice in web development for their scalability and versatility. However, managing a growing library of SVG icons in your application can be challenging. In this guide, we will address how to dynamically render multiple SVG icons in your React application using TypeScript, allowing you to effectively manage a larger set of icons without cluttering your component logic.

The Problem: Managing Multiple Icons

Imagine you have a directory filled with SVG icons that you can import and use throughout your application. For example, you may start with five icons like this:

Now, as your project grows, you might need to add 30 or more icons. Manually rendering each icon can lead to repetitive code and is not maintainable.

Your goal is to find a way to dynamically render all the available icons without writing custom JSX for each one. This is where the challenge lies—how to correctly implement this dynamic rendering in TypeScript.

Implementation Steps

Here’s how you can efficiently render your icons dynamically:

In this code:

The underscore _ is used for the key (not needed here), while Icon is the imported component (SVG icon).

We create a new array of JSX elements that correspond to each SVG icon.

Alternatively, you might prefer to structure it like this:

This snippet achieves the same result. Here’s how it works:

For each icon name, we retrieve the corresponding icon component and return it as JSX.

Final Notes

Make sure to manage your TypeScript types properly. If you're encountering type errors regarding intrinsic attributes, ensure that your SVG components are typed correctly. Here’s a common error you might face:

This indicates that TypeScript does not recognize the props you’re trying to pass. Double-check your icon components to ensure they are set up correctly to accept these attributes.
