The Problem

When trying to fetch user data that contains information about student enrollments, many developers find that even though they can see the data in the console, they struggle to inject that data into the HTML of the webpage. For instance, we have a JavaScript snippet that fetches user information, but the dynamically created HTML does not render as expected:

The Solution

To resolve this issue, you need to ensure the following steps are followed to inject the fetched data into your HTML. Here’s how to successfully integrate the user information into a webpage.

Step 1: Create a Container in Your HTML

First, ensure you have a <div> container in your HTML where you want the user data to be displayed. For example:

This div will serve as the placeholder for the dynamic content generated from the fetched data.

Step 2: Fetch Data from the API

The next step is to fetch the data from your API endpoint. However, merely fetching the data is not enough. You need to await the resolutions of all promises returned by the fetch calls to avoid displaying undefined values. Here is an improved fetching logic.

Step 4: Catching Errors

It is always a good practice to include error handling in your code. You can catch potential errors by adding a .catch() method at the end of your Promise chain.

Summary of Changes

Here’s a quick summary of what you need to do to successfully display user information on your webpage:

Create a container: Make sure there’s a designated area in your HTML to display the data (e.g., a <div> with an ID).

Use return in fetch() calls: This ensures that promises are properly returned and managed.

Incorporate error handling: Use .catch() to gracefully handle any potential errors that may arise during the fetch process.

By following this structured approach, you can dynamically display user enrollment information fetched from your API in a reliable and user-friendly manner.
