# @ember-data/serializer
Provides JSON, REST and JSON:API Implementations of the legacy Serializer Interface
> [!WARNING]
> **⚠️ This is a legacy package** not recommended for new applications.
>
> **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 serializer, consider writing a [Handler](https://warp-drive.io/api/@warp-drive/core/request/interfaces/Handler)
> instead to be used with the [RequestManager](https://warp-drive.io/api/@warp-drive/core/classes/RequestManager)
## Installation
This package is currently installed when installing `ember-data`.
If installing `@ember-data/` packages individually install using your javascript package manager of choice. For instance with [pnpm](https://pnpm.io/)
```sh
pnpm add @ember-data/serializer
```

## 🚀 Setup
If using `ember-data` no additional setup is necesssary.
> **Note**
> When using [ember-data](https://github.com/warp-drive-data/warp-drive/blob/main/packages/-ember-data) the below
> configuration is handled for you automatically.
To use legacy serializers you will need to have installed and configured the LegacyNetworkHandler from [@ember-data/legacy-compat](https://github.com/warp-drive-data/warp-drive/blob/main/packages/-ember-data)
```sh
pnpm add @ember-data/legacy-compat
```
```ts
import Store, { CacheHandler } from '@ember-data/store';
import RequestManager from '@ember-data/request';
import { LegacyNetworkHandler } from '@ember-data/legacy-compat';
export default class extends Store {
requestManager = new RequestManager()
.use([LegacyNetworkHandler])
.useCache(CacheHandler);
}
```
## Usage
To use as either a per-type or application serializer, export one of the
implementations within the `serializers/` directory of your app as appropriate.
For instance, to configure an application serializer to use `JSON:API`
*app/serializers/application.ts*
```ts
export { default } from '@ember-data/serializer/json-api';
```
By default serializers are resolved by looking for a serializer with the same name in the `serializers/` folder as the `type` given to `store.serializerFor()`, falling back to looking for a serializer named `application`.
**Overriding Resolution**
If you would like to avoid using resolver semantics and your application has only one or a few serializers, you may ovveride the `serializerFor` hook on the store.
```ts
import Store from '@ember-data/store';
import Serializer from '@ember-data/serializer/json-api';
class extends Store {
#serializer = new Serializer();
serializerFor() {
return this.#serializer;
}
}
```
