Build Status NPM version XO code style Coverage Status

A free and unlimited API for Google Translate 💵🚫 for Node.js.


  • Auto language detection
  • Spelling correction
  • Language correction
  • Fast and reliable – it uses the same servers that translate.google.com uses

Why this fork?

This fork of original matheuss/google-translate-api contains several improvements:

  • New option client="t|gtx". Setting client="gtx" seems to work even with outdated token, see this discussion for details
  • Fixed extraction of TKK ceed from current https://translate.google.com sources (via @vitalets/google-translate-token)
  • Removed unsecure unsafe-eval dependency (See #2)
  • Added daily CI tests to get notified if Google API changes
  • Added support for custom tld (especially to support translate.google.cn, see #7)
  • Added support for outputting pronunciation (see #17)
  • Added support for custom got options. It allows to use proxy and bypass request limits (see #25)
  • Added support for language extensions from outside of the API (See #18)


npm install @vitalets/google-translate-api


From automatic language detection to English:

const translate = require('@vitalets/google-translate-api');
translate('Ik spreek Engels', {to: 'en'}).then(res => {
    //=> I speak English
    //=> nl
}).catch(err => {

From English to Dutch with a typo:

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

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

translate('I spea Dutch!', {from: 'en', to: 'nl'}).then(res => {
    //=> Ik spea Nederlands!
    //=> false
    //=> I [speak] Dutch!
    //=> true
}).catch(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 => ...);


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 => {

Does it work from web page context?

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

  • from (object)
    • language (object)
