react-native-mlkit-translate

A React Native wrapper around Google's ML Kit Translate library, which provides free on-device translations and uses the very same ML models as Google Translate's offline mode.

IMPORTANT: This package currently supports only Android. Contributions are highly welcome, so feel free to add an IOS implementation as well :)

Getting started

$ npm install react-native-mlkit-translate --save

Mostly automatic installation

$ react-native link react-native-mlkit-translate

API

translate(text: string, sourceLanguage: string, targetLanguage: string, requireWifiToDownloadModel?: boolean): Promise <string>

Translate a word/sentence from a source to a target language.

• text - the text to be translated
• sourceLanguage - the code for the source language, i.e. the language of text (language codes)
• targetLanguage - the code for the target language, i.e. the language to which text should be translated (language codes)
• requireWifiToDownloadModel (default value: true) - in case the language model has not been download yet, it will try to download it on-the-fly. In such case, this flag will determine whether it should require Wifi to download the model (~30MB).
• Returns the translated text

getDownloadedModels(): Promise<string[]>

Retrieve all translation models downloaded in the mobile.

• Returns an array with the language codes for the downloaded models (language codes).

deleteDownloadedModel(languageCode: string): Promise<void>

Delete a specific language model from the mobile.

• languageCode - the language code for the translation model (language codes)

downloadModel(languageCode: string, requireWifi?: boolean): Promise<void>

Download a specific language model to the mobile.

• languageCode - the language code for the translation model (language codes)
• requireWifi (default value: true) - determine whether it should require Wifi to download the model (~30MB).
