Creating a model and assigning values in TypeScript

I am currently developing an angular application and need to send data to a post API. The JSON structure I am working with is as follows:

{
    "name": "julie",
    "id": 1,
    "PersonalDetails": {
        "homeId": 23,
        "homeName": "Julie Home"
    },
    "OfficialDetails": {
        "OfficeId": 45,
        "OfficeAddress": "Near townhall"
    }
}

Within my component, I need to populate this data by setting values using variables in the component and then sending it to my post API method. As I anticipate needing to send more models in the future with similar structures but different data, I am considering creating an interface. However, being new to TypeScript, I am unsure of how to proceed.

Could you advise on the best approach to creating a model for this data and setting values? How should I go about creating a model/interface and populating its values?

Answer №1

To effectively organize your data, it is recommended to create a basic interface that outlines the structure of your information.

For instance:

interface YourData {
  id?: number;
  name?: string;
  PersonalDetails?: PersonalDetails
  OfficialDetails?: OfficialDetails
}

It is also beneficial to establish separate interfaces for each subsection within your data. In this scenario, consider defining interfaces for PersonalDetails and OfficialDetails.

interface PersonalDetails {
  homeId?: number;
  homeName?: string;
}

interface OfficialDetails {
  OfficeId?: number;
  OfficeAddress?: string;
}

By setting up interfaces, you can easily expand and adjust your data in the future.

Once you have created the necessary interfaces, you can access the values by casting them using the interfaces. For example:

sendData(payload: YourData): Observable<YourData> {
  return this.http.post<YourData>(payload)
    .pipe(
      ...
    );
}
