How to Implement a Progress Bar for Uploading Data in React Native

Are you new to React Native and eager to learn how to create a progress bar for your data uploads? You're not alone! Many developers find implementing features like file uploads a challenge, especially when it comes to displaying the upload progress to users. In this guide, we'll walk you through the process of setting up a progress bar for data uploads in your React Native app using axios. Let's dive in!

Understanding the Problem

When you upload files or data in applications, it's essential to keep users informed about the progress. A progress bar is a perfect way to visualize this progress, enhancing user experience and making the app feel more responsive. However, if you're not familiar with React Native and its state management, this task can seem daunting.

To illustrate, the code snippet from the question shows a simple upload function using axios, along with an intention to display the progress via a progress bar. The given structure, while a good start, lacks the piece necessary to update the progress dynamically.

The Solution: Implementing the Progress Bar

Step 1: Use State for Tracking Progress

The first step is to set up a state variable to hold the progress percentage. This is crucial because React components render their UI based on state changes, and to see the progress bar in action, you'll need to update it continuously as the upload progresses.

Here's how you can set your initial state:

Step 2: Modify the Upload Progress Function

Next, you'll adjust the uploadProgress function to calculate and update the percentage of the upload. This function will also log the progress to the console, as shown in the original question.

Step 3: Update the Axios Upload Function

In your axios upload call, make sure to include the onUploadProgress property to track the progress with the uploadProgress function we created.
