Introduction to Formatting Form Data in Angular

When building web applications using Angular and TypeScript, one of the essential tasks is formatting your form data correctly to send it to a server. This can become particularly tricky when you are working with dynamic forms containing arrays of data, such as symptoms in a healthcare application. In this post, we will walk through a step-by-step process of how to achieve this using TypeScript.

Understanding the Problem

Imagine you have a form for participants where users can select their occupation, provide an address, and state various symptoms. After a user fills out the form, you get a value similar to this:

However, the server requires the data in a specific format, where the symptoms should be associated with their IDs. For example:

To achieve this, we need to merge the symptom data with the user's selections from the form.

Solution Overview

We will create a new object that combines the relevant values from the participant form and the symptoms array. This process requires mapping the symptoms results to their corresponding IDs.

Step-by-Step Implementation

Data Structure Setup:

Ensure you have both the user's selections (form values) and symptoms data.

Conclusion

Formatting form data to meet the server's requirements can seem daunting, especially when working with array structures. However, by mapping the values appropriately and organizing the data correctly, you can ensure smooth communication between your Angular application and the server.

With this guide, you should be well-equipped to format your form data effectively, making your application more robust and user-friendly. Don't forget to test the final output to ensure everything works according to your server-side expectations!
