Documentation / @ember-data/adapter / rest / default

Defined in: packages/adapter/src/rest.ts:293

⚠️ This is LEGACY documentation for a feature that is no longer encouraged to be used. If starting a new app or thinking of implementing a new adapter, consider writing a Handler instead to be used with the RequestManager

The REST adapter allows your store to communicate with an HTTP server by transmitting JSON via XHR.

This adapter is designed around the idea that the JSON exchanged with the server should be conventional. It builds URLs in a manner that follows the structure of most common REST-style web services.

Success and failure

The REST adapter 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.

JSON Structure

The REST adapter expects the JSON returned from your server to follow these conventions.

Object Root

The JSON payload should be an object that contains the record inside a root property. For example, in response to a GET request for /posts/1, the JSON should look like this:

js
{
  "posts": {
    "id": 1,
    "title": "I'm Running to Reform the W3C",
    "author": "Yehuda Katz"
  }
}

Similarly, in response to a GET request for /posts, the JSON should look like this:

js
{
  "posts": [
    {
      "id": 1,
      "title": "I'm Running to Reform the W3C",
      "author": "Yehuda Katz"
    },
    {
      "id": 2,
      "title": "Rails is omakase",
      "author": "D2H"
    }
  ]
}

Note that the object root can be pluralized for both a single-object response and an array response: the REST adapter is not strict on this. Further, if the HTTP server responds to a GET request to /posts/1 (e.g. the response to a findRecord query) with more than one object in the array, Ember Data will only display the object with the matching ID.

Conventional Names

Attribute names in your JSON payload should be the camelCased versions of the attributes in your Ember.js models.

For example, if you have a Person model:

app/models/person.js
js
import Model, { attr } from '@ember-data/model';

export default Model.extend({
  firstName: attr('string'),
  lastName: attr('string'),
  occupation: attr('string')
});

The JSON returned should look like this:

js
{
  "people": {
    "id": 5,
    "firstName": "Zaphod",
    "lastName": "Beeblebrox",
    "occupation": "President"
  }
}

Relationships

Relationships are usually represented by ids to the record in the relationship. The related records can then be sideloaded in the response under a key for the type.

js
{
  "posts": {
    "id": 5,
    "title": "I'm Running to Reform the W3C",
    "author": "Yehuda Katz",
    "comments": [1, 2]
  },
  "comments": [{
    "id": 1,
    "author": "User 1",
    "message": "First!",
  }, {
    "id": 2,
    "author": "User 2",
    "message": "Good Luck!",
  }]
}

If the records in the relationship are not known when the response is serialized it's also possible to represent the relationship as a URL using the links key in the response. Ember Data will fetch this URL to resolve the relationship when it is accessed for the first time.

js
{
  "posts": {
    "id": 5,
    "title": "I'm Running to Reform the W3C",
    "author": "Yehuda Katz",
    "links": {
      "comments": "/posts/5/comments"
    }
  }
}

Errors

If a response is considered a failure, the JSON payload is expected to include a top-level key errors, detailing any specific issues. For example:

js
{
  "errors": {
    "msg": "Something went wrong"
  }
}

This adapter does not make any assumptions as to the format of the errors object. It will simply be passed along as is, wrapped in an instance of InvalidError or AdapterError. The serializer can interpret it afterwards.

Customization

Endpoint path customization

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

app/adapters/application.js
js
import RESTAdapter from '@ember-data/adapter/rest';

export default class ApplicationAdapter extends RESTAdapter {
  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
js
import RESTAdapter from '@ember-data/adapter/rest';

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

Headers customization

Some APIs require HTTP headers, e.g. to provide an API key. Arbitrary headers can be set as key/value pairs on the RESTAdapter's headers object and EmberData will send them along with each ajax request.

app/adapters/application.js
js
import RESTAdapter from '@ember-data/adapter/rest';

export default class ApplicationAdapter extends RESTAdapter {
  get headers() {
    return {
      'API_KEY': 'secret key',
      'ANOTHER_HEADER': 'Some header value'
    };
  }
}

coalesceFindRequests

Get Signature

ts
get coalesceFindRequests(): boolean;

Defined in: packages/adapter/src/rest.ts:431

By default the RESTAdapter will send each find request coming from a store.find or from accessing a relationship separately to the server. If your server supports passing ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests within a single runloop.

For example, if you have an initial payload of:

javascript
{
  post: {
    id: 1,
    comments: [1, 2]
  }
}

By default calling post.comments will trigger the following requests(assuming the comments haven't been loaded before):

GET /comments/1
GET /comments/2

If you set coalesceFindRequests to true it will instead trigger the following request:

GET /comments?ids[]=1&ids[]=2

Setting coalesceFindRequests to true also works for store.find requests and belongsTo relationships accessed within the same runloop. If you set coalesceFindRequests: true

javascript
store.findRecord('comment', 1);
store.findRecord('comment', 2);

will also send a request to: GET /comments?ids[]=1&ids[]=2

Note: Requests coalescing rely on URL building strategy. So if you override buildURL in your app groupRecordsForFindMany more likely should be overridden as well in order for coalescing to work.

Returns

boolean

Set Signature

ts
set coalesceFindRequests(value): void;

Defined in: packages/adapter/src/rest.ts:439

By default the store will try to coalesce all findRecord calls within the same runloop into as few requests as possible by calling groupRecordsForFindMany and passing it into a findMany call. You can opt out of this behaviour by either not implementing the findMany hook or by setting coalesceFindRequests to false.

Parameters
value

boolean

Returns

void

Optional

If your adapter implements findMany, setting this to true will cause findRecord requests triggered within the same runloop to be coalesced into one or more calls to adapter.findMany. The number of calls made and the records contained in each call can be tuned by your adapter's groupRecordsForHasMany method.

Implementing coalescing using this flag and the associated methods does not always offer the right level of correctness, timing control or granularity. If your application would be better suited coalescing across multiple types, coalescing for longer than a single runloop, or with a more custom request structure, coalescing within your application adapter may prove more effective.

addObserver()

Call Signature

ts
addObserver<Target>(
   key, 
   target, 
   method): this;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/observable.d.ts:333

Adds an observer on a property.

This is the core method used to register an observer for a property.

Once you call this method, any time the key's value is set, your observer will be notified. Note that the observers are triggered any time the value is set, regardless of whether it has actually changed. Your observer should be prepared to handle that.

There are two common invocation patterns for .addObserver():

  • Passing two arguments:
    • the name of the property to observe (as a string)
    • the function to invoke (an actual function)
  • Passing three arguments:
    • the name of the property to observe (as a string)
    • the target object (will be used to look up and invoke a function on)
    • the name of the function to invoke on the target object (as a string).
app/components/my-component.js
import Component from '@ember/component';

export default Component.extend({
  init() {
    this._super(...arguments);

    // the following are equivalent:

    // using three arguments
    this.addObserver('foo', this, 'fooDidChange');

    // using two arguments
    this.addObserver('foo', (...args) => {
      this.fooDidChange(...args);
    });
  },

  fooDidChange() {
    // your custom logic code
  }
});

Observer Methods

Observer methods have the following signature:

app/components/my-component.js
import Component from '@ember/component';

export default Component.extend({
  init() {
    this._super(...arguments);
    this.addObserver('foo', this, 'fooDidChange');
  },

  fooDidChange(sender, key, value, rev) {
    // your code
  }
});

The sender is the object that changed. The key is the property that changes. The value property is currently reserved and unused. The rev is the last property revision of the object when it changed, which you can use to detect if the key value has really changed or not.

Usually you will not need the value or revision parameters at the end. In this case, it is common to write observer methods that take only a sender and key value as parameters or, if you aren't interested in any of these values, to write an observer that has no parameters at all.

findAll()

ts
findAll(
   store, 
   type, 
   sinceToken, 
snapshotRecordArray): Promise<AdapterPayload>;

Defined in: packages/adapter/src/rest.ts:544

Called by the store in order to fetch a JSON array for all of the records for a given type.

The findAll method makes an Ajax (HTTP GET) request to a URL computed by buildURL, and returns a promise for the resulting payload.

Parameters

store

default

type

ModelSchema

sinceToken

null

snapshotRecordArray

SnapshotRecordArray

Returns

Promise<AdapterPayload>

promise

Overrides

default.findAll


findBelongsTo()

ts
findBelongsTo(
   store, 
   snapshot, 
   url, 
relationship): Promise<AdapterPayload>;

Defined in: packages/adapter/src/rest.ts:751

Called by the store in order to fetch the JSON for the unloaded record in a belongs-to relationship that was originally specified as a URL (inside of links).

For example, if your original payload looks like this:

js
{
  "person": {
    "id": 1,
    "name": "Tom Dale",
    "links": { "group": "/people/1/group" }
  }
}

This method will be called with the parent record and /people/1/group.

The findBelongsTo method will make an Ajax (HTTP GET) request to the originally specified URL.

The format of your links value will influence the final request URL via the urlPrefix method:

  • Links beginning with //, http://, https://, will be used as is, with no further manipulation.

  • Links beginning with a single / will have the current adapter's host value prepended to it.

  • Links with no beginning / will have a parentURL prepended to it, via the current adapter's buildURL.

Parameters

store

default

snapshot

Snapshot

url

string

relationship

any

meta object describing the relationship

Returns

Promise<AdapterPayload>

promise


findHasMany()

ts
findHasMany(
   store, 
   snapshot, 
   url, 
relationship): Promise<AdapterPayload>;

Defined in: packages/adapter/src/rest.ts:697

Called by the store in order to fetch a JSON array for the unloaded records in a has-many relationship that were originally specified as a URL (inside of links).

For example, if your original payload looks like this:

js
{
  "post": {
    "id": 1,
    "title": "Rails is omakase",
    "links": { "comments": "/posts/1/comments" }
  }
}

This method will be called with the parent record and /posts/1/comments.

The findHasMany method will make an Ajax (HTTP GET) request to the originally specified URL.

The format of your links value will influence the final request URL via the urlPrefix method:

  • Links beginning with //, http://, https://, will be used as is, with no further manipulation.

  • Links beginning with a single / will have the current adapter's host value prepended to it.

  • Links with no beginning / will have a parentURL prepended to it, via the current adapter's buildURL.

Parameters

store

default

snapshot

url

string

relationship

Record<string, unknown>

meta object describing the relationship

Returns

Promise<AdapterPayload>

promise


findMany()

ts
findMany(
   store, 
   type, 
   ids, 
snapshots): Promise<AdapterPayload>;

Defined in: packages/adapter/src/rest.ts:656

Called by the store in order to fetch several records together if coalesceFindRequests is true

For example, if the original payload looks like:

js
{
  "id": 1,
  "title": "Rails is omakase",
  "comments": [ 1, 2, 3 ]
}

The IDs will be passed as a URL-encoded Array of IDs, in this form:

ids[]=1&ids[]=2&ids[]=3

Many servers, such as Rails and PHP, will automatically convert this URL-encoded array into an Array for you on the server-side. If you want to encode the IDs, differently, just override this (one-line) method.

The findMany method makes an Ajax (HTTP GET) request to a URL computed by buildURL, and returns a promise for the resulting payload.

Parameters

store

default

type

ModelSchema

ids

string[]

snapshots

Snapshot<unknown>[]

Returns

Promise<AdapterPayload>

promise


findRecord()

ts
findRecord(

get()

Call Signature

ts
get<K>(key): RESTAdapter[K];

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/observable.d.ts:121

Retrieves the value of a property from the object.

This method is usually similar to using object[keyName] or object.keyName, however it supports both computed properties and the unknownProperty handler.

Because get unifies the syntax for accessing all these kinds of properties, it can make many refactorings easier, such as replacing a simple property with a computed property, or vice versa.

Computed Properties

Computed properties are methods defined with the property modifier declared at the end, such as:

javascript
import { computed } from '@ember/object';

fullName: computed('firstName', 'lastName', function() {
  return this.get('firstName') + ' ' + this.get('lastName');
})

When you call get on a computed property, the function will be called and the return value will be returned instead of the function itself.

Unknown Properties

Likewise, if you try to call get on a property whose value is undefined, the unknownProperty() method will be called on the object. If this method returns any value other than undefined, it will be returned instead. This allows you to implement "virtual" properties that are not defined upfront.

Type Parameters
K

K extends keyof RESTAdapter

Parameters
key

K

Returns

RESTAdapter[K]

The property value or undefined.

javascript
record.getProperties('firstName', 'lastName', 'zipCode');
// { firstName: 'John', lastName: 'Doe', zipCode: '10011' }

groupRecordsForFindMany()

ts
groupRecordsForFindMany(store, snapshots): Snapshot<unknown>[][];

Defined in: packages/adapter/src/rest.ts:884

Organize records into groups, each of which is to be passed to separate calls to findMany.

This implementation groups together records that have the same base URL but differing ids. For example /comments/1 and /comments/2 will be grouped together because we know findMany can coalesce them together as /comments?ids[]=1&ids[]=2

It also supports urls where ids are passed as a query param, such as /comments?id=1 but not those where there is more than 1 query param such as /comments?id=2&name=David Currently only the query param of id is supported. If you need to support others, please override this or the _stripIDFromURL method.

It does not group records that have differing base urls, such as for example: /posts/1/comments/2 and /posts/2/comments/3

Parameters

store

default

snapshots

Snapshot<unknown>[]

Returns

Snapshot<unknown>[][]

an array of arrays of records, each of which is to be loaded separately by findMany.

Overrides

default.groupRecordsForFindMany


handleResponse()

ts
handleResponse(
   status, 
   headers, 
   payload, 
   requestData): Payload | typeof _AdapterError;

Defined in: packages/adapter/src/rest.ts:937

Takes an ajax response, and returns the json payload or an error.

By default this hook just returns the json payload passed to it. You might want to override it in two cases:

  1. Your API might return useful results in the response headers. Response headers are passed in as the second argument.

  2. Your API might return errors as successful responses with status code 200 and an Errors text or object. You can return a InvalidError or a AdapterError (or a sub class) from this hook and it will automatically reject the promise and put your record into the invalid or error state.

Returning a InvalidError from this method will cause the record to transition into the invalid state and make the errors object available on the record. When returning an InvalidError the store will attempt to normalize the error data returned from the server using the serializer's extractErrors method.

Parameters

status

number

headers

Record<string, string>

payload

Payload

requestData

RequestData

the original request information

Returns

Payload | typeof _AdapterError

init()

ts
init(_properties): void;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/core.d.ts:114

An overridable method called when objects are instantiated. By default, does nothing unless it is overridden during class definition.

Example:

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  init() {
    alert(`Name is ${this.get('name')}`);
  }
});

let steve = Person.create({
  name: 'Steve'
});

// alerts 'Name is Steve'.

NOTE: If you do override init for a framework class like Component from @ember/component, be sure to call this._super(...arguments) in your init declaration! If you don't, Ember may not have an opportunity to do important setup work, and you'll see strange behavior in your application.

set()

Call Signature

ts
set<K, T>(key, value): T;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/observable.d.ts:208

Sets the provided key or path to the value.

javascript
record.set("key", value);

This method is generally very similar to calling object["key"] = value or object.key = value, except that it provides support for computed properties, the setUnknownProperty() method and property observers.

Computed Properties

If you try to set a value on a key that has a computed property handler defined (see the get() method for an example), then set() will call that method, passing both the value and key instead of simply changing the value itself. This is useful for those times when you need to implement a property that is composed of one or more member properties.

Unknown Properties

If you try to set a value on a key that is undefined in the target object, then the setUnknownProperty() handler will be called instead. This gives you an opportunity to implement complex "virtual" properties that are not predefined on the object. If setUnknownProperty() returns undefined, then set() will simply set the value on the object.

Property Observers

In addition to changing the property, set() will also register a property change with the object. Unless you have placed this call inside of a beginPropertyChanges() and endPropertyChanges(), any "local" observers (i.e. observer methods declared on the same object), will be called immediately. Any "remote" observers (i.e. observer methods declared on another object) will be placed in a queue and called at a later time in a coalesced manner.

shouldBackgroundReloadAll()

ts
shouldBackgroundReloadAll(store, snapshotRecordArray): boolean;

Defined in: packages/adapter/src/index.ts:893

This method is used by the store to determine if the store should reload a record array after the store.findAll method resolves with a cached record array.

This method is only checked by the store when the store is returning a cached record array.

If this method returns true the store will re-fetch all records from the adapter.

For example, if you do not want to fetch complex data over a mobile connection, or if the network is down, you can implement shouldBackgroundReloadAll as follows:

javascript
shouldBackgroundReloadAll(store, snapshotArray) {
  let { downlink, effectiveType } = navigator.connection;

  return downlink > 0 && effectiveType === '4g';
}

By default this method returns true, indicating that a background reload should always be triggered.

Parameters

store

default

snapshotRecordArray

SnapshotRecordArray

Returns

boolean

Since

1.13.0

Inherited from

default.shouldBackgroundReloadAll


shouldBackgroundReloadRecord()

ts
shouldBackgroundReloadRecord(store, snapshot): boolean;

Defined in: packages/adapter/src/index.ts:857

This method is used by the store to determine if the store should reload a record after the store.findRecord method resolves a cached record.

This method is only checked by the store when the store is returning a cached record.

If this method returns true the store will re-fetch a record from the adapter.

For example, if you do not want to fetch complex data over a mobile connection, or if the network is down, you can implement shouldBackgroundReloadRecord as follows:

javascript
shouldBackgroundReloadRecord(store, snapshot) {
  let { downlink, effectiveType } = navigator.connection;

  return downlink > 0 && effectiveType === '4g';
}

By default, this hook returns true so the data for the record is updated in the background.

Parameters

store

default

snapshot

Snapshot

Returns

boolean

Since

1.13.0

Inherited from

default.shouldBackgroundReloadRecord


shouldReloadAll()

ts
shouldReloadAll(store, snapshotRecordArray): boolean;

Defined in: packages/adapter/src/index.ts:821

This method is used by the store to determine if the store should reload all records from the adapter when records are requested by store.findAll.

If this method returns true, the store will re-fetch all records from the adapter. If this method returns false, the store will resolve immediately using the cached records.

For example, if you are building an events ticketing system, in which users can only reserve tickets for 20 minutes at a time, and want to ensure that in each route you have data that is no more than 20 minutes old you could write:

javascript
shouldReloadAll(store, snapshotArray) {
  let snapshots = snapshotArray.snapshots();

  return snapshots.any((ticketSnapshot) => {
    let lastAccessedAt = ticketSnapshot.attr('lastAccessedAt');
    let timeDiff = moment().diff(lastAccessedAt, 'minutes');

    if (timeDiff > 20) {
      return true;
    } else {
      return false;
    }
  });
}

This method would ensure that whenever you do store.findAll('ticket') you will always get a list of tickets that are no more than 20 minutes old. In case a cached version is more than 20 minutes old, findAll will not resolve until you fetched the latest versions.

By default, this method returns true if the passed snapshotRecordArray is empty (meaning that there are no records locally available yet), otherwise, it returns false.

Note that, with default settings, shouldBackgroundReloadAll will always re-fetch all the records in the background even if shouldReloadAll returns false. You can override shouldBackgroundReloadAll if this does not suit your use case.

Parameters

store

snapshotRecordArray

SnapshotRecordArray

Returns

boolean

shouldReloadRecord()

ts
shouldReloadRecord(store, snapshot): boolean;

Defined in: packages/adapter/src/index.ts:766

This method is used by the store to determine if the store should reload a record from the adapter when a record is requested by store.findRecord.

If this method returns true, the store will re-fetch a record from the adapter. If this method returns false, the store will resolve immediately using the cached record.

For example, if you are building an events ticketing system, in which users can only reserve tickets for 20 minutes at a time, and want to ensure that in each route you have data that is no more than 20 minutes old you could write:

javascript
shouldReloadRecord(store, ticketSnapshot) {
  let lastAccessedAt = ticketSnapshot.attr('lastAccessedAt');
  let timeDiff = moment().diff(lastAccessedAt, 'minutes');

  if (timeDiff > 20) {
    return true;
  } else {
    return false;
  }
}

This method would ensure that whenever you do store.findRecord('ticket', id) you will always get a ticket that is no more than 20 minutes old. In case the cached version is more than 20 minutes old, findRecord will not resolve until you fetched the latest version.

By default this hook returns false, as most UIs should not block user interactions while waiting on data update.

Note that, with default settings, shouldBackgroundReloadRecord will always re-fetch the records in the background even if shouldReloadRecord returns false. You can override shouldBackgroundReloadRecord if this does not suit your use case.

Parameters

store

default

snapshot

Snapshot

Returns

boolean

default.shouldReloadRecord


sortQueryParams()

ts
sortQueryParams(obj): Record<string, unknown>;

Defined in: packages/adapter/src/rest.ts:368

By default, the RESTAdapter will send the query params sorted alphabetically to the server.

For example:

js
store.query('posts', { sort: 'price', category: 'pets' });

will generate a requests like this /posts?category=pets&sort=price, even if the parameters were specified in a different order.

That way the generated URL will be deterministic and that simplifies caching mechanisms in the backend.

Setting sortQueryParams to a falsey value will respect the original order.

In case you want to sort the query parameters with a different criteria, set sortQueryParams to your custom sort function.

app/adapters/application.js
js
import RESTAdapter from '@ember-data/adapter/rest';

export default class ApplicationAdapter extends RESTAdapter {
  sortQueryParams(params) {
    let sortedKeys = Object.keys(params).sort().reverse();
    let len = sortedKeys.length, newParams = {};

    for (let i = 0; i < len; i++) {
      newParams[sortedKeys[i]] = params[sortedKeys[i]];
    }

    return newParams;
  }
}

Parameters

obj

Record<string, unknown>

Returns

Record<string, unknown>

toString()

ts
toString(): string;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/core.d.ts:347

Returns a string representation which attempts to provide more information than Javascript's toString typically does, in a generic way for all Ember objects.

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend();
person = Person.create();
person.toString(); //=> "<Person:ember1024>"

If the object's class is not defined on an Ember namespace, it will indicate it is a subclass of the registered superclass:

javascript
const Student = Person.extend();
let student = Student.create();
student.toString(); //=> "<(subclass of Person):ember1025>"

If the method toStringExtension is defined, its return value will be included in the output.

javascript
const Teacher = Person.extend({
  toStringExtension() {
    return this.get('fullName');
  }
});
teacher = Teacher.create();
teacher.toString(); //=> "<Teacher:ember1026:Tom Dale>"

Returns

string

updateRecord()

ts
updateRecord(
   store, 
   schema, 
snapshot): Promise<AdapterPayload>;

Defined in: packages/adapter/src/rest.ts:803

Called by the store when an existing record is saved via the save method on a model record instance.

The updateRecord method serializes the record and makes an Ajax (HTTP PUT) request to a URL computed by buildURL.

See serialize for information on how to customize the serialized form of a record.

create()

Call Signature

ts
readonly static create<C>(this): InstanceType<C>;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/core.d.ts:487

Creates an instance of a class. Accepts either no arguments, or an object containing values to initialize the newly instantiated object with.

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  helloWorld() {
    alert(`Hi, my name is ${this.get('name')}`);
  }
});

let tom = Person.create({
  name: 'Tom Dale'
});

tom.helloWorld(); // alerts "Hi, my name is Tom Dale".

create will call the init function if defined during AnyObject.extend

If no arguments are passed to create, it will not set values to the new instance during initialization:

javascript
let noName = Person.create();
noName.helloWorld(); // alerts undefined

NOTE: For performance reasons, you cannot declare methods or computed properties during create. You should instead declare methods and computed properties when using extend.

extend()

ts
readonly static extend<Statics, Instance, M>(this, ...mixins?): Readonly<Statics> & EmberClassConstructor<Instance> & MergeArray<M>;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/core.d.ts:442

Creates a new subclass.

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  say(thing) {
    alert(thing);
   }
});

This defines a new subclass of EmberObject: Person. It contains one method: say().

You can also create a subclass from any existing class by calling its extend() method. For example, you might want to create a subclass of Ember's built-in Component class:

javascript
import Component from '@ember/component';

const PersonComponent = Component.extend({
  tagName: 'li',
  classNameBindings: ['isAdministrator']
});

When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special _super() method:

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  say(thing) {
    let name = this.get('name');
    alert(`${name} says: ${thing}`);
  }
});

const Soldier = Person.extend({
  say(thing) {
    this._super(`${thing}, sir!`);
  },
  march(numberOfHours) {
    alert(`${this.get('name')} marches for ${numberOfHours} hours.`);
  }
});

let yehuda = Soldier.create({
  name: 'Yehuda Katz'
});

yehuda.say('Yes');  // alerts "Yehuda Katz says: Yes, sir!"

The create() on line #17 creates an instance of the Soldier class. The extend() on line #8 creates a subclass of Person. Any instance of the Person class will not have the march() method.

You can also pass Mixin classes to add additional properties to the subclass.

javascript
import EmberObject from '@ember/object';
import Mixin from '@ember/object/mixin';

const Person = EmberObject.extend({
  say(thing) {
    alert(`${this.get('name')} says: ${thing}`);
  }
});

const SingingMixin = Mixin.create({
  sing(thing) {
    alert(`${this.get('name')} sings: la la la ${thing}`);
  }
});

const BroadwayStar = Person.extend(SingingMixin, {
  dance() {
    alert(`${this.get('name')} dances: tap tap tap tap `);
  }
});

The BroadwayStar class contains three methods: say(), sing(), and dance().

reopenClass()

ts
readonly static reopenClass<C>(this, ...mixins): C;

Defined in: node_modules/.pnpm/ember-s_b51cd27d01243d453ba52dedc3d113b0/node_modules/ember-source/types/stable/@ember/object/core.d.ts:595

Augments a constructor's own properties and functions:

javascript
import EmberObject from '@ember/object';

const MyObject = EmberObject.extend({
  name: 'an object'
});

MyObject.reopenClass({
  canBuild: false
});

MyObject.canBuild; // false
o = MyObject.create();

In other words, this creates static properties and functions for the class. These are only available on the class and not on any instance of that class.

javascript
import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  name: '',
  sayHello() {
    alert(`Hello. My name is ${this.get('name')}`);
  }
});

Person.reopenClass({
  species: 'Homo sapiens',

  createPerson(name) {
    return Person.create({ name });
  }
});

let tom = Person.create({
  name: 'Tom Dale'
});
let yehuda = Person.createPerson('Yehuda Katz');

tom.sayHello(); // "Hello. My name is Tom Dale"
yehuda.sayHello(); // "Hello. My name is Yehuda Katz"
alert(Person.species); // "Homo sapiens"

Note that species and createPerson are not valid on the tom and yehuda variables. They are only valid on Person.
