Live Demo with Nodejs

Install

npm install translation-google

Usage

From automatic language detection to Chinese:

const {translate} = require('@paiva/translation-google');

translate('This is Google Translate', {to: 'zh-cn'}).then(res => {
    console.log(res.text);
    //=> 这是Google翻译
    console.log(res.from.language.iso);
    //=> en
}).catch(err => {
    console.error(err);
});

For Chinese user, try this:

const {translate} = require('@paiva/translation-google');

translate('This is Google Translate', {to: 'zh-cn', suffix: 'cn'}).then(res => {
    console.log(res.text);
    //=> 这是Google翻译
    console.log(res.from.language.iso);
    //=> en
}).catch(err => {
    console.error(err);
});

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

translate('This is Google Translat', {from: 'en', to: 'zh-cn'}).then(res => {
    console.log(res);
    console.log(res.text);
    //=> 这是Google翻译
    console.log(res.from.text.autoCorrected);
    //=> false
    console.log(res.from.text.value);
    //=> This is Google [Translate]
    console.log(res.from.text.didYouMean);
    //=> true
}).catch(err => {
    console.error(err);
});

Proxying requests through Tor rotator to overcome quota limit:

# use docker image for Tor cluster
docker run -d -p 5566:5566 -p 4444:4444 --env tors=25 mattes/rotating-proxy

const {translate} = require('@paiva/translation-google');
const {HttpsProxyAgent} = require('https-proxy-agent');

translate('This is Google Translate', {
    to: 'zh-cn',
    agent: new HttpsProxyAgent('http://localhost:8118')
}).then(res => {
    console.log(res.text);
    //=> 这是Google翻译
    console.log(res.from.language.iso);
    //=> en
}).catch(err => {
    console.error(err);
});

API

translate(text, options)

text

Type: string

The text to be translated

options

Type: object

suffix

Type: string Default: com

The TLD to use. By default, it is com, but a Chinese user, in China Mainland, could set the suffix to 'cn' to make it work.

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 (not case sensitive) contained in languages.js.

raw

Type: boolean Default: false

If true, the returned object will have a raw property with the raw response (string) from Google Translate.

agent

Type: object Default: undefined

An object representing http, https and http2 keys for http.Agent, https.Agent and http2wrapper.Agent instance. This allows to proxy the requests.

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 (booelan) – 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('This is Google Translat').then(res => {
    console.log(res.from.text.value);
    //=> This is [Google Translate]
}).catch(err => {
    console.error(err);
});

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