An example of an AI chatbot conversation about best practices for file uploads in React.
What are the best practices for file upload in React?
When implementing file uploads in React, consider using controlled components, validating file types, and providing user feedback.
How can I validate the file type before uploading?
You can use the File API to check the file type in the onChange event of your file input. For example, check file.type against allowed types.
What about handling large file uploads?
For large files, consider using chunked uploads or libraries like react-dropzone that support drag-and-drop and file size limits.
Can I show a progress bar during the upload?
Yes, you can use the XMLHttpRequest or fetch API with a progress event listener to update a progress bar as the file uploads.
