Creating a dynamic progress bar for your JavaScript fetch calls can greatly improve the user experience and boost satisfaction. Here are a few steps to get you started:
Create an HTML structure: First, create an HTML structure for your progress bar. You can use a
div
element with a width of 0% and a background color. Thisdiv
will represent the progress bar.Use JavaScript fetch method: Next, use the JavaScript
fetch
method to make the network request. The fetch method returns aPromise
that resolves to the Response object representing the response to your request.Track the progress of the fetch call: You can use the
Response.body
property to access aReadableStream object
, which represents the body of the response. You can then use theReadableStream.getReader()
method to get a reader and track the progress of the fetch call by reading chunks of data.Update the progress bar: As you receive chunks of data, you can use JavaScript to update the width of the progress bar. For example, you can divide the total number of bytes received by the total number of bytes to be received, and multiply the result by 100 to get the percentage. You can then use this percentage to update the width of the progress bar.
Show the completion of the fetch call: Finally, you can use JavaScript to show the completion of the fetch call. For example, you can change the background color of the progress bar to green when the fetch call is complete, or display a message to indicate that the data has been loaded.
By following these steps, you can create a dynamic progress bar for your JavaScript fetch calls that provides a better user experience and improves satisfaction.
