Is there support for json-api about class-transformer

[pleerock]

Hi,
looks like its a regular json and you need to create proper classes for this, like:

class StructuredJson {
     links: StructuredJsonLinks;
     data: StructuredJsonData[];
}
class StructuredJsonLinks {
     self: string;
     next: string;
     last: string;
}
class StructuredJsonData ....

How do you think your data should be transformed by this library from json to objects?

That makes sense for the links, but when you have an article in the above example you would like to have a model class like this:

export class Article{
  title:string;
  author: Person;
  comments: Comments[];
}

export class Person{
  firstName: string;
  lastName: string;
  twitter: string;

  // Optional:
  link:string // But is this something a person should know?
}

export class Comment{
  id:number;
  body: string;
  author: Person;
}

I'm not very familiar with serializing/deserializing (yet).
But for me it seems, the hard part would be to check the relationships, see if this data is "included", and if so, create object with this data within the main data object.

The 'data' has the id and attributes in different fields. So that would mean 2 maps?

import {deserialize} from "serializer.ts/Serializer";

this.http
    .get("users.json")
    .map(res => res.json())
    .map(res => deserialize<Article>(article, res.data.id)) // get the ID
    .map(article => deserialize<Article>(article, res.data.attributes)) // get the attributes and add them to the existing article??
    .map(article => deserialize<Person>(article, res.data.relationships)) // get the relationships and add them to the existing article??
    .subscribe(users => {
        // now "users" is type of User[] and each user have getName() and isKid() methods available
        console.log(users);
    });

hoping there is a faster/better way to do this? :-)

hmm. just thinking..

might be possible to use something like flatmap or switchmap or something to combine data and relationships or something.?
Or do something with ES6 Array destructuring to get the proper values..
Really have to take a deep dive into ES6 / Typescript.

looks like what you want is not a part of this library, and it should not be. You simply need to create a map function that will convert your json in your specific format into modelled format (only persons, articles and other your models), and then user deserialization

[the-ult]

thanks I'll look into that. And see if I get it working with your library.

[pleerock]

thanks

@the-ult did you get a pattern worked out? would be nice to see it

[the-ult]

@jcrben I started a new job and never got a chance to get it worked out. Sorry.

[johannesschobel]

Dear @jcrben ,
