    Google Translate API for Node

    A Node.js module for working with the Google Cloud Translation API.

    Automatically handles bulk translations that exceed the Google Translation API query limit.

    Installation

    Install via npm

    npm install google-translate --save
    

    Usage overview

    Require module and pass in your API Google project API key after enabling the API service. Note: This module currently doesn't support oauth authentication.

    var googleTranslate = require('google-translate')(apiKey);
    

    String translation:

    googleTranslate.translate('My name is Brandon', 'es', function(err, translation) {
      console.log(translation.translatedText);
      // =>  Mi nombre es Brandon
    });
    

    Language detection:

    googleTranslate.detectLanguage('Gracias', function(err, detection) {
      console.log(detection.language);
      // =>  es
    });
    

    API

    Callbacks: All methods take a callback as their last parameter. Upon method completion, callbacks are passed an error if exists (otherwise null), followed by a response object or array: callback(err, data).

    Bulk translations: Passing an array of strings greater than 5k characters will be result in multiple concurrent asynchronous calls. Once all calls are completed, the response will be parsed, merged, and passed to the callback. The default maximum concurrent requests is 10. You can override this value by passing in a new limit when you pass in your API key: require('google-translate')(apiKey, concurrentLimit)

    Translate

    Translate one or more strings.

    googleTranslate.translate(strings, source, target, callback)
    
    • strings: Required. Can be a string or an array of strings
    • source: Optional. Google will autodetect the source locale if not specified. Available languages
    • target: Required. Language to translate to. Available languages
    • callback: Required.

    Example: Translate a string to German (de) and autodetect source language

    googleTranslate.translate('Hello', 'de', function(err, translation) {
      console.log(translation);
      // =>  { translatedText: 'Hallo', originalText: 'Hello', detectedSourceLanguage: 'en' }
    });
    

    Example: Translate an array of English (en) strings to German (de)

    googleTranslate.translate(['Hello', 'Thank you'], 'en', 'de', function(err, translations) {
      console.log(translations);
      // =>  [{ translatedText: 'Hallo', originalText: 'Hello' }, ...]
    });
    

    Detect language

    Detect language of string or each string in an array.

    googleTranslate.detectLanguage(strings, callback)
    
    • strings: Required. Can be a string or an array of strings
    • callback: Required.

    Example: Detect language from a string

    googleTranslate.detectLanguage('Hello', function(err, detection){
      console.log(detection);
      // =>  { language: "en", isReliable: false, confidence: 0.5714286, originalText: "Hello" }
    });
    

    Example: Detect language from an array of strings

    googleTranslate.detectLanguage(['Hello', 'Danke'], function(err, detections) {
      console.log(detections);
      // =>  [{ language: "en", isReliable: false, confidence: 0.5714286, originalText: "Hello" }, ...]
    });
    

    Get supported languages

    Retrieve all languages supported by the Google Translate API.

    googleTranslate.getSupportedLanguages(target, callback)
    
    • target: Optional. If specified, response will include the name of the language translated to the specified target language
    • callback: Required.

    Example: Get all supported language codes

    googleTranslate.getSupportedLanguages(function(err, languageCodes) {
      console.log(languageCodes);
      // => ['af', 'ar', 'be', 'bg', 'ca', 'cs', ...]
    });
    

    Example: Get all supported language codes with language names in German

    googleTranslate.getSupportedLanguages('de', function(err, languageCodes) {
      console.log(languageCodes);
      // => [{ language: "en", name: "Englisch" }, ...]
    });
