How to Post an Array with Objects in Angular

When building applications using Angular, you may often find yourself needing to send data to a backend API. One common scenario is posting an array of objects, especially if you have an array of IDs and you want to structure that data properly. This guide will walk you through how to achieve this in a clear and concise way.

The Challenge

Imagine you have selected multiple jobs, and each job has a unique identifier (ID). You wish to format this data for posting: every job ID should be an individual object with a specific structure that includes a state. Let's look at how you can transform your array of job IDs into the desired format.

Given Code Snippet

You start with this initial code, which collects the selected job IDs into an array:

This results in an array like this:

Next, you create a payload but notice that its structure isn't what you need:

This payload appears as follows:

[[See Video to Reveal this Text or Code Snippet]]

However, you need a payload structured like this:

The Solution

To achieve the desired structure for your payload, you can utilize the map function in TypeScript. Here’s how to proceed:

Step-by-Step Transformation

Map the Job IDs to Required Object Structure:
Instead of creating a single object with an array of IDs, you need to create an object for each job ID.

Updated Code Implementation:
Replace your previous payload creation with the following code snippet:

This code will iterate over each job ID in selectedJobsId and return a corresponding object with the required properties.

Resulting Payload

The output of the above transformation will give you a properly structured array:

Conclusion

In Angular, structuring your data correctly for API POST requests is critical for effective communication with your backend services. By utilizing the map function in TypeScript, you can convert an array of IDs into a well-structured array of objects, making your data handling straightforward and efficient.

Next time you face a task of formatting your data for posting, remember this approach! Happy coding!
