Exploring Angular2 and TypeScript integration with complex nested JSON responses

I am currently working on a project that involves a front-end app built in Angular. Upon sending a request to my back end API, I receive a nested JSON response, as shown in the attached screenshot.

My query pertains to understanding how I can process this response using TypeScript and then display it on the view. (Just to reiterate, my objective is to create a table tree in the view).

View JSON response

Answer №1

Seeking guidance on processing data with TypeScript and displaying it in the view.

There are two main queries to address here:

How to process data with TypeScript?

Angular's HTTP service simplifies JSON parsing.

If not utilizing HTTP, resort to using JSON.parse method.

How to display data in the view?

Employ Angular's data binding feature for this purpose.
