ngx-jsonapi v1 to v2 update guide

ngx-jsonapi v2 has arrived! While this is a major version change (from 1.x to 2.x), we've put in a lot of work to keep the hard breaking changes to a minimum.

package.json

Update version of ngx-jsonapi to 2.0.0-rc.1 (or last version)

Services

• Extended Service
  • Remove ISchema elements
• Extended Resource
  • Add @Autoregister on every extended Resource
  • Set initial values for attributes property
  • Add hasMany relationships with DocumentCollection<SomeResource>()
  • Add hasOne relationships with DocumentResource<SomeResource>()

authors.service.ts example:

Before

import { Injectable } from '@angular/core';
import { Service, ISchema, Resource } from 'ngx-jsonapi';

@Injectable()
export class AuthorsService extends Service<Author> {
    public resource = Author;
    public type = 'authors';
    public schema: ISchema = {
        relationships: {
            books: {
                hasMany: true
            },
            photos: {
                hasMany: true
            }
        }
    };
}
export class Author extends Resource {
    public attributes: {
        name: string;
        date_of_birth: string;
        date_of_death: string;
        created_at: string;
        updated_at: string;
    };
}

Now

import { Injectable } from '@angular/core';
import { Autoregister, Service, Resource, DocumentCollection, DocumentResource } from 'ngx-jsonapi';
import { Book } from '../books/books.service';
import { Photo } from '../photos/photos.service';

export class Author extends Resource {
    public attributes = {
        name: 'default name',
        date_of_birth: ''
    };

    public relationships = {
        books: new DocumentCollection<Book>(),
        photo: new DocumentResource<Photo>()
    };
}

@Injectable()
@Autoregister()
export class AuthorsService extends Service<Author> {
    public resource = Author;
    public type = 'authors';
}

Controllers

• Remove every localfilter on all() methods. You need to use rxjs pipe .map().
• Replace every ICollection<YourResource> type with DocumentCollection<YourResource>

authors.controller.ts example:

Before

public authors: ICollection<Author>;

Now

public authors: DocumentCollection<Author>;

Views

• Replace every .$toArray with .data on collections.
• Replace every yourcollection (as Object) with yourcollection.data on collections.
• Add on your *ngFor trackBy function. Example: let resource of collection.data; trackBy: collection.trackBy.
• Replace every .$is_loading with .is_loading on collections (bool builded is recommended).
• Replace every content with builded, if you try to detect a builded json document.

author.template.html example:

Before

<span *ngIf="author.relationships.photos.content === 'collection'">
    <img *ngFor="let photo of book.relationships.photos.data.$toArray" title="Book id #{{ photo.id }}" />
</span>

Now

<span *ngIf="author.relationships.photos.builded">
    <img *ngFor="let photo of author.relationships.photos.data" title="Book id #{{ photo.id }}" />
</span>

authors.template.html example:

Before

<tr *ngFor="let author of authors.$toArray">
    <td>{{ author.id }}</td>
    <td>{{ author.attributes.name }}</td>
</tr>

Now

<tr *ngFor="let author of authors.data; trackBy: authors.trackBy">
    <td>{{ author.id }}</td>
    <td>{{ author.attributes.name }}</td>
</tr>
