## Implements

- `ITranslatorConnector`

## Constructors

### Constructor

> **new LiteTranslatorConnector**(): `LiteTranslatorConnector`

#### Returns

`LiteTranslatorConnector`

#### Inherited from

DataConnector\<Language, Language, \{ language: string \} \| undefined\>.constructor

## Methods

### fetch()

#### Call Signature

> **fetch**(): `Promise`\<`ILanguageList`\>

Defined in: [packages/apputils/src/translation.ts:24](https://github.com/jupyterlite/jupyterlite/blob/14439ec34e3cade5baa221a050277e15da9d0c06/packages/apputils/src/translation.ts#L24)

Retrieve an item from the data connector.

##### Returns

`Promise`\<`ILanguageList`\>

A promise that resolves with a data payload if available.

#### Notes
The promise returned by this method may be rejected if an error occurs in
retrieving the data. Nonexistence of an `id` will succeed with `undefined`.

##### Implementation of

`ITranslatorConnector.fetch`

##### Overrides

`DataConnector.fetch`

#### Call Signature

> **fetch**(`opts`): `Promise`\<`Language`\>

Defined in: [packages/apputils/src/translation.ts:25](https://github.com/jupyterlite/jupyterlite/blob/14439ec34e3cade5baa221a050277e15da9d0c06/packages/apputils/src/translation.ts#L25)

##### Parameters

###### opts

###### language

`string`

##### Returns

`Promise`\<`Language`\>

### list()

> **list**(`query?`): `Promise`\<\{ `ids`: (`undefined` \| \{ `language`: `string`; \})[]; `values`: `Language`[]; \}\>

Retrieve the list of items available from the data connector.

#### Parameters

##### query?

`string`

Subclasses should reimplement if they support a back-end that can list.

#### Implementation of

`ITranslatorConnector.list`

#### Inherited from

`DataConnector.list`
