Displaying Data in Angular from an HTTP Service in JSON Format

Working with APIs can be a challenge, especially when it comes to fetching and rendering data. If you're using Angular and retrieving data that is formatted as strings instead of proper JSON, you may run into some issues. In this guide, we'll discuss how to effectively display data coming from an HTTP service in JSON format using Angular.

The Problem

You may have encountered a situation where your API returns data in a format that looks like this:

It appears as a list of strings, which is not directly usable in Angular for rendering. Your model may look like this:

When you try to bind this data using ngFor, you find that the fields are not displaying correctly. Instead, you're getting the entire string representation rather than object properties.

The Solution

To resolve this issue, follow these organized steps to convert your string data into a proper JSON object format that Angular can handle.

Step 1: Modify Your Data Retrieval Logic

In your Angular service where you're retrieving data, you need to parse the strings into JSON objects. You can modify your existing data handling method as follows:

Step 2: Update Your Component's Data Subscription

Ensure that your component subscribes correctly to the updated Observable:

Step 3: Adjust Your HTML for Rendering

With the data correctly parsed, you can now display it in your HTML template. Use this structure to iterate through the data:

Final Output

After implementing these changes, your console should show parsed objects, and your Angular template should display each entry's properties correctly:

Name

Description

Other

Conclusion

By following these steps, you will effectively resolve issues related to displaying JSON data fetched from an HTTP service in Angular. You now have a clearer understanding of how to handle data parsing from string formats and display it properly in a user-friendly way. If you encounter further issues, revisiting your API responses and ensuring correct data types can help you debug effectively!
