A common requirement is to track the upload progress for a smoother user experience. If you're using Axios for your HTTP requests, you're in luck! Axios provides a handy feature called onUploadProgress that helps track how much of a file has been uploaded. However, many developers struggle with how to utilize this feature effectively, especially when trying to manage the uploaded percentage in their components. Let’s break down how to accomplish this in a React environment. The Problem: Accessing Upload Percentage in Your Component You might be able to log the upload progress to the console, but the challenge arises when you want to display the upload percentage within a component, such as List.js. The question at hand is: How can you make this percentage value accessible within your component? Sample Code Overview Here’s the foundational code snippet for uploading a user list with Axios, along with the upload progress logging: [[See Video to Reveal this Text or Code Snippet]] We see that the onUploadProgress function captures the loaded and total bytes of the uploaded file. The percentage is calculated and logged. The Solution: Managing Upload Progress State To make the upload percentage accessible in List.js, you need to follow these structured steps: Step 1: Introduce State for Upload Percentage In your List component, you need to maintain state for the upload progress. This can be done using the traditional state management or a global state if you are using Redux or a similar library. For example: [[See Video to Reveal this Text or Code Snippet]] Step 2: Dispatch an Action to Update State Since you're likely using a state management approach, you will need an action that updates this state. You need to create an action called setUploadProgress. Here's an example of how you might define this action: [[See Video to Reveal this Text or Code Snippet]] Step 3: Update Your onUploadProgress Handler Modify your upload function to accept a parameter for the onUploadProgress handler. This enables you to dispatch the setUploadProgress action directly when the upload progresses.

You might use a local state, Redux state, or context API, depending on your project’s architecture. Conclusion By following these steps and structuring your approach, you will not only track file upload progress using Axios's onUploadProgress but also convey that information to your components effectively. Tracking upload progress enhances user experience significantly, ensuring users are aware of the file upload status. Remember, the key takeaway is to manage state effectively and ensure that your upload progress is directly linked to a reusable handler that can be dispatched at any time. Happy coding!
