plugin for [ML Kit Translation](https://developers.google.com/ml-kit/language/translation).[1](#fn:1) [ ![Deliver Live Updates to your Capacitor app with Capawesome Cloud](../../../../assets/external/cloud.capawesome.io/assets/banners/cloud-build-and-deploy-capacitor-apps.69628c3f.png) ](https://cloud.capawesome.io/) ## Use Cases[ΒΆ](#use-cases "Permanent link") The Translation plugin is typically used to translate text directly on the device, for example: * **Chat translation**: Translate incoming messages into the language of the user. * **Content translation**: Let users translate user-generated content such as comments, reviews, or posts. * **Offline translation**: Download language models in advance so users can translate text without an internet connection. * **Travel apps**: Help travelers translate text on the go, even when roaming without a data connection. ## Compatibility[ΒΆ](#compatibility "Permanent link") | Plugin Version | Capacitor Version | Status | | -------------- | ----------------- | -------------- | | 8.x.x | \>=8.x.x | Active support | | 7.x.x | 7.x.x | Deprecated | | 6.x.x | 6.x.x | Deprecated | | 5.x.x | 5.x.x | Deprecated | ## Installation[ΒΆ](#installation "Permanent link") You can use our **AI-Assisted Setup** to install the plugin. Add the [Capawesome Skills](https://github.com/capawesome-team/skills) to your AI tool using the following command: `[](#%5F%5Fcodelineno-0-1)npx skills add capawesome-team/skills --skill capacitor-plugins ` Then use the following prompt: `` [](#%5F%5Fcodelineno-1-1)Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capacitor-mlkit/translation` plugin in my project. `` If you prefer **Manual Setup**, install the plugin by running the following commands and follow the platform-specific instructions below: `[](#%5F%5Fcodelineno-2-1)npm install @capacitor-mlkit/translation [](#%5F%5Fcodelineno-2-2)npx cap sync ` **Attention**: This plugin **only supports CocoaPods** for iOS dependency management. Swift Package Manager (SPM) is not supported for the ML Kit SDK, see [this comment](https://github.com/googlesamples/mlkit/issues/180#issuecomment-1298964099). ### Android[ΒΆ](#android "Permanent link") #### Variables[ΒΆ](#variables "Permanent link") If needed, you can define the following project variable in your app’s `variables.gradle` file to change the default version of the dependency: * `$mlkitTranslateVersion` version of `com.google.mlkit:translate` (default: `17.0.3`) This can be useful if you encounter dependency conflicts with other plugins in your project. ### iOS[ΒΆ](#ios "Permanent link") #### Minimum Deployment Target[ΒΆ](#minimum-deployment-target "Permanent link") Make sure to set the deployment target in your `ios/App/Podfile` to at least `15.5`: `[](#%5F%5Fcodelineno-3-1)platform :ios, '15.5' ` ## Configuration[ΒΆ](#configuration "Permanent link") No configuration required for this plugin. ## Demo[ΒΆ](#demo "Permanent link") A working example can be found here: [robingenz/capacitor-mlkit-plugin-demo](https://github.com/robingenz/capacitor-mlkit-plugin-demo) ## Usage[ΒΆ](#usage "Permanent link") The following examples show how to translate a text, download a language model, list the downloaded language models, and delete a downloaded language model. ### Translate a text[ΒΆ](#translate-a-text "Permanent link") Use the `translate(...)` method to translate a text from a source language to a target language. If the language model for the given languages is not downloaded yet, it will be downloaded automatically, which may take some time. Only available on Android and iOS: `[](#%5F%5Fcodelineno-4-1)import { Translation, Language } from '@capacitor-mlkit/translation'; [](#%5F%5Fcodelineno-4-2) [](#%5F%5Fcodelineno-4-3)const translate = async () => { [](#%5F%5Fcodelineno-4-4) const { text } = await Translation.translate({ [](#%5F%5Fcodelineno-4-5) text: 'Good morning!', [](#%5F%5Fcodelineno-4-6) sourceLanguage: Language.English, [](#%5F%5Fcodelineno-4-7) targetLanguage: Language.German, [](#%5F%5Fcodelineno-4-8) }); [](#%5F%5Fcodelineno-4-9) return text; [](#%5F%5Fcodelineno-4-10)}; ` ### Download a language model[ΒΆ](#download-a-language-model "Permanent link") Download a language model in advance to enable offline translation. Language models are around 30MB in size, so be sure to only download the models you need and only download them using a WiFi connection unless the user has specified otherwise. Only available on Android and iOS: `[](#%5F%5Fcodelineno-5-1)import { Translation, Language } from '@capacitor-mlkit/translation'; [](#%5F%5Fcodelineno-5-2) [](#%5F%5Fcodelineno-5-3)const downloadModel = async () => { [](#%5F%5Fcodelineno-5-4) await Translation.downloadModel({ [](#%5F%5Fcodelineno-5-5) language: Language.English, [](#%5F%5Fcodelineno-5-6) }); [](#%5F%5Fcodelineno-5-7)}; ` ### List the downloaded language models[ΒΆ](#list-the-downloaded-language-models "Permanent link") Get the languages for which a model has already been downloaded to the device. Only available on Android and iOS: `[](#%5F%5Fcodelineno-6-1)import { Translation } from '@capacitor-mlkit/translation'; [](#%5F%5Fcodelineno-6-2) [](#%5F%5Fcodelineno-6-3)const getDownloadedModels = async () => { [](#%5F%5Fcodelineno-6-4) const { languages } = await Translation.getDownloadedModels(); [](#%5F%5Fcodelineno-6-5) return languages; [](#%5F%5Fcodelineno-6-6)}; ` ### Delete a downloaded language model[ΒΆ](#delete-a-downloaded-language-model "Permanent link") Delete the language model for a given language, for example to free up storage space on the device. Only available on Android and iOS: `[](#%5F%5Fcodelineno-7-1)import { Translation, Language } from '@capacitor-mlkit/translation'; [](#%5F%5Fcodelineno-7-2) [](#%5F%5Fcodelineno-7-3)const deleteDownloadedModel = async () => { [](#%5F%5Fcodelineno-7-4) await Translation.deleteDownloadedModel({ [](#%5F%5Fcodelineno-7-5) language: Language.English, [](#%5F%5Fcodelineno-7-6) }); [](#%5F%5Fcodelineno-7-7)}; ` ## API[ΒΆ](#api "Permanent link") * [deleteDownloadedModel(...)](#deletedownloadedmodel) * [downloadModel(...)](#downloadmodel) * [getDownloadedModels()](#getdownloadedmodels) * [translate(...)](#translate) * [Interfaces](#interfaces) * [Enums](#enums) ### deleteDownloadedModel(...)[ΒΆ](#deletedownloadedmodel "Permanent link") `[](#%5F%5Fcodelineno-8-1)deleteDownloadedModel(options: DeleteDownloadedModelOptions) => Promise ` Delete the language model for the given language.

All methods are only available on Android and iOS, so there is no web implementation. ### Which languages are supported?[ΒΆ](#which-languages-are-supported "Permanent link") The plugin supports more than 50 languages, including English, German, Spanish, French, Chinese, and Japanese. See the `Language` enum in the [API](#api) section for the complete list. ### Does the translation work offline?[ΒΆ](#does-the-translation-work-offline "Permanent link") Yes, the translation is performed on the device using downloaded language models. Use the `downloadModel(...)` method to download a language model in advance, for example while the device is connected to a WiFi network. Otherwise, the model is downloaded automatically on the first call to `translate(...)`, which may take some time. ### How much storage do the language models require?[ΒΆ](#how-much-storage-do-the-language-models-require "Permanent link") Language models are around 30MB in size, so be sure to only download the models you need. You can delete a model that is no longer needed using the `deleteDownloadedModel(...)` method. ### What if I don't know the source language of the text?[ΒΆ](#what-if-i-dont-know-the-source-language-of-the-text "Permanent link") The `translate(...)` method requires a source language. You can use the ML Kit Language Identification plugin to detect the language of a text before translating it. ### Can I install this plugin using Swift Package Manager?[ΒΆ](#can-i-install-this-plugin-using-swift-package-manager "Permanent link") No, this plugin only supports CocoaPods for iOS dependency management because the ML Kit SDK itself does not support Swift Package Manager. Also make sure to set the deployment target in your `ios/App/Podfile` to at least `15.5` (see [Installation](#installation)). ## Related Plugins[ΒΆ](#related-plugins "Permanent link") * [Speech Recognition](https://capawesome.io/docs/sdks/capacitor/speech-recognition/): Transcribe speech into text, for example to translate it afterwards. * [Speech Synthesis](https://capawesome.io/docs/sdks/capacitor/speech-synthesis/): Synthesize speech from text, for example to read translated text aloud. * [App Language](https://capawesome.io/docs/sdks/capacitor/app-language/): Manage the app's own language override, independent of the device language. ## Terms & Privacy[ΒΆ](#terms-privacy "Permanent link") This plugin uses the [Google ML Kit](https://developers.google.com/ml-kit): * [Terms & Privacy](https://developers.google.com/ml-kit/terms) * [Android Data Disclosure](https://developers.google.com/ml-kit/android-data-disclosure) * [iOS Data Disclosure](https://developers.google.com/ml-kit/ios-data-disclosure) ## Newsletter[ΒΆ](#newsletter "Permanent link") Stay up to date with the latest news and updates about the Capawesome, Capacitor, and Ionic ecosystem by subscribing to our [Capawesome Newsletter](https://cloud.capawesome.io/newsletter/). ## Changelog[ΒΆ](#changelog "Permanent link") See [CHANGELOG.md](https://github.com/capawesome-team/capacitor-mlkit/blob/main/packages/translation/CHANGELOG.md). ## License[ΒΆ](#license "Permanent link") See [LICENSE](https://github.com/capawesome-team/capacitor-mlkit/blob/main/packages/translation/LICENSE). --- 1.
