@darkside-developers/translate

A Node.js library for fetching Google translate result.

Installation

npm install @darkside-developers/translate

Usage

From automatic language detection to English:

const { translate } = require('@darkside-developers/translate');

translate('මම ඔයාට ආදරෙයි', {to: 'en'}).then(res => {
    console.log(res.text);
    //=> I Love You
}).catch(err => {
    console.error(err);
});

Please note that maximum text length for single translation call is 5000 characters.

From English to Dutch with a type:

translate('I spea Dutch!', {from: 'en', to: 'nl'}).then(res => {
    console.log(res.text);
    //=> Ik spreek Nederlands!
    console.log(res.from.text.autoCorrected);
    //=> true
    console.log(res.from.text.value);
    //=> I [speak] Dutch!
    console.log(res.from.text.didYouMean);
    //=> false
}).catch(err => {
    console.error(err);
});

Sometimes, the API will not use the auto corrected text in the translation:

translate('I spea Dutch!', {from: 'en', to: 'nl'}).then(res => {
    console.log(res);
    console.log(res.text);
    //=> Ik spea Nederlands!
    console.log(res.from.text.autoCorrected);
    //=> false
    console.log(res.from.text.value);
    //=> I [speak] Dutch!
    console.log(res.from.text.didYouMean);
    //=> true
}).catch(err => {
    console.error(err);
});

You can also add languages in the code and use them in the translation:

translate = require('google-translate-api');
translate.languages['sr-Latn'] = 'Serbian Latin';

translate('translator', {to: 'sr-Latn'}).then(res => ...);

Proxy

Google Translate has request limits. If too many requests are made, you can either end up with a 429 or a 503 error. You can use proxy to bypass them:

const tunnel = require('tunnel');
translate('Ik spreek Engels', {to: 'en'}, {
    agent: tunnel.httpsOverHttp({
    proxy: { 
      host: 'whateverhost',
      proxyAuth: 'user:pass',
      port: '8080',
      headers: {
        'User-Agent': 'Node'
      }
    }
  }
)}).then(res => {
    // do something
}).catch(err => {
    console.error(err);
});

Does it work from web page context?

No. https://translate.google.com does not provide CORS http headers allowing access from other domains.

API

translate(text, [options], [gotOptions])

text

Type: string

The text to be translated

options

Type: object

from

Type: string Default: auto

The text language. Must be auto or one of the codes/names (not case sensitive) contained in languages.js

to

Type: string Default: en

The language in which the text should be translated. Must be one of the codes/names (case sensitive!) contained in languages.js.

client

Type: string Default: "t"

Query parameter client used in API calls. Can be t|gtx.

tld

Type: string Default: "com"

gotOptions

Type: object

The got options: https://github.com/sindresorhus/got#options

Returns an object:

• text (string) – The translated text.
• from (object)
  • language (object)
    • didYouMean (boolean) - true if the API suggest a correction in the source language
    • iso (string) - The code of the language that the API has recognized in the text
  • text (object)
    • autoCorrected (boolean) – true if the API has auto corrected the text
    • value (string) – The auto corrected text or the text with suggested corrections
    • didYouMean (boolean) – true if the API has suggested corrections to the text
• raw (string) - If options.raw is true, the raw response from Google Translate servers. Otherwise, ''.

Note that res.from.text will only be returned if from.text.autoCorrected or from.text.didYouMean equals to true. In this case, it will have the corrections delimited with brackets ([ ]):

translate('I spea Dutch').then(res => {
    console.log(res.from.text.value);
    //=> I [speak] Dutch
}).catch(err => {
    console.error(err);
});

Otherwise, it will be an empty string ('').
