Class JSONAPIAdapter

public
Extends: RESTAdapter
Since: v1.13.0

The JSONAPIAdapter is the default adapter used by Ember Data. It is responsible for transforming the store's requests into HTTP requests that follow the JSON API format.

JSON API Conventions

The JSONAPIAdapter uses JSON API conventions for building the URL for a record and selecting the HTTP verb to use with a request. The actions you can take on a record map onto the following URLs in the JSON API adapter:

Action HTTP Verb URL
`store.findRecord('post', 123)` GET /posts/123
`store.findAll('post')` GET /posts
Update `postRecord.save()` PATCH /posts/123
Create `store.createRecord('post').save()` POST /posts
Delete `postRecord.destroyRecord()` DELETE /posts/123

Success and failure

The JSONAPIAdapter will consider a success any response with a status code of the 2xx family ("Success"), as well as 304 ("Not Modified"). Any other status code will be considered a failure.

On success, the request promise will be resolved with the full response payload.

Failed responses with status code 422 ("Unprocessable Entity") will be considered "invalid". The response will be discarded, except for the errors key. The request promise will be rejected with a InvalidError. This error object will encapsulate the saved errors value.

Any other status codes will be treated as an adapter error. The request promise will be rejected, similarly to the invalid case, but with an instance of AdapterError instead.

Endpoint path customization

Endpoint paths can be prefixed with a namespace by setting the namespace property on the adapter:

app/adapters/application.js
1
2
3
4
5
import JSONAPIAdapter from '@ember-data/adapter/json-api';

export default class ApplicationAdapter extends JSONAPIAdapter {
  namespace = 'api/1';
}

Requests for the person model would now target /api/1/people/1.

Host customization

An adapter can target other hosts by setting the host property.

app/adapters/application.js
1
2
3
4
5
import JSONAPIAdapter from '@ember-data/adapter/json-api';

export default class ApplicationAdapter extends JSONAPIAdapter {
  host = 'https://api.example.com';
}

Requests for the person model would now target https://api.example.com/people/1.
