Examples

From automatic language detection to English:

translate('Tu es incroyable!', { to: 'en' }).then(res => {
  console.log(res.text); // OUTPUT: You are amazing!
}).catch(err => {
  console.error(err);
});

From English to French, with a typo:

translate('Thank you', { from: 'en', to: 'fr' }).then(res => {
  console.log(res.text); // OUTPUT: Je vous remercie
  console.log(res.from.autoCorrected); // OUTPUT: true
  console.log(res.from.text.value); // OUTPUT: [Thank] you
  console.log(res.from.text.didYouMean); // OUTPUT: false
}).catch(err => {
  console.error(err);
});

Sometimes Google Translate won't auto correct:

translate('Thank you', { from: 'en', to: 'fr' }).then(res => {
  console.log(res.text); // OUTPUT: ''
  console.log(res.from.autoCorrected); // OUTPUT: false
  console.log(res.from.text.value); // OUTPUT: [Thank] you
  console.log(res.from.text.didYouMean); // OUTPUT: true
}).catch(err => {
  console.error(err);
});

Credits to matheuss for writing the original version of this library. I rewrote this, with improvements and without using many external libraries, as his library was not actively developed and had vulnerabilities.
