To prevent multiple copies of React from loading, you can use a bundler such as Webpack or Rollup to build your application and ensure that React and its dependencies are only included once.
Here are a few steps you can take to prevent multiple copies of React from loading:
- Remove duplicate dependencies: Check your
package.jsonfile and remove any duplicate dependencies that may include React.
- Use a single version of React: Make sure that all of your React dependencies are using the same version of React. Mixing different versions of React can cause issues and lead to duplication.
- Check for global React: Make sure that you are not including React globally in your HTML file. If you are including React via a script tag, make sure that it is only included once.
By taking these steps, you can ensure that only one copy of React is loaded in your application and prevent issues that may arise from duplication.
