How to Dynamically Render react-icons Based on Database Strings in Your React App

Creating a user-friendly interface often involves displaying information in a visually appealing way. In React, it is common to incorporate icons alongside text to enhance the user experience. However, what if you want to make your icons dynamic and sourced from a database? In this post, we will guide you through the process of rendering react-icons based on strings retrieved from your database.

The Challenge: Using Icons Dynamically

You may have a scenario where you're trying to display several information boxes, each accompanied by its corresponding icon. The challenge arises when you want to eliminate hard-coded icons and instead fetch icon names from a database. The initial code setup may look like this:

This structure works but doesn’t provide the flexibility you need for adding more components based on dynamic data.

Solution: Dynamic Icon Rendering with react-icons

Step 1: Import the Icons

To achieve dynamic icon rendering, first import the desired icon sets from react-icons. For instance, if you are planning to use Font Awesome icons, you would do the following:

Step 2: Create a Component for Dynamic Icons

You can create a reusable component that will accept the icon name as a prop. This component will locate the correct icon component based on the string received from your database.

Here’s how you can create that custom component called DynamicFaIcon:

Conclusion

By following these steps, you can successfully implement dynamic icon rendering based on strings from your database in React. This not only saves time when adding new icons but also allows for a more streamlined approach to managing your components. Now, when you fetch an icon name from your database, simply pass it to the DynamicFaIcon component, and it will handle the rest.

Feel free to implement this method in your projects, and watch as your user interface transforms into a more dynamic and engaging experience!
