How to Properly Use jQuery UI with Parcel for React Apps

The Problem

When trying to implement features from jQuery UI, such as draggable or resizable components in a React app, you might initially succeed during the development phase. However, when you attempt to add your Parcel output to a demo page, you hit a wall with undefined errors which can leave you puzzled.

Symptoms

As a quick overview, here’s what typically happens:

During development using yarn start, features work correctly.

Upon bundling and adding to a demo page, the aforementioned types of errors appear in the console.

In this guide, we'll explore the solution to this issue and clarify the proper way to include jQuery UI within your React app using Parcel.

The Solution

The key to solving this problem lies in how you integrate the jQuery UI library. Instead of importing individual components, leveraging the entire jQuery UI package in one go can simplify the integration process.

Step-by-Step Guide

Here's a concise approach to resolving the jQuery UI error by modifying your package management and imports.

Install jquery-ui-dist Package

First, you'll want to use the jquery-ui-dist package instead of importing individual jQuery UI components. To do this, run:

Why This Works

The reason this solution resolves the issue is that the jquery-ui-dist package contains the complete compiled version of jQuery UI, ensuring all components, widgets, and dependencies are properly included and initialized. When you import it as a complete library, you avoid potential pitfalls of missing components that might cause the undefined errors we saw before.

Conclusion

Integrating libraries like jQuery UI within modern front-end frameworks can be tricky, especially when utilizing bundlers such as Parcel. By following these simple steps, switching to jquery-ui-dist not only resolves common errors but also enhances the maintainability of your code.

Now that you have the knowledge to successfully integrate jQuery UI with Parcel, you can focus on building more interactive and dynamic React applications without unnecessary roadblocks. If you encounter further issues, don’t hesitate to reach out or explore community resources for support.

Happy Coding!
