google-translate-api

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

Features

• 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 Setting client="gtx" seems to work even with outdated token, see this discussion for details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 support for custom tld (especially to support translate.google.cn, see #7)
• Added support for outputting pronunciation (see #17)
• Added support for language extensions from outside of the API (See #18)

Install

npm install @danke77/google-translate-api

Usage

From automatic language detection to English:

const Translator = require('@danke77/google-translate-api');

const translator = new Translator({
    from: 'auto',
    to: 'en',
    raw: false,
    client: 'gtx', // t
    tld: 'cn',
});

const res = await translator.translate('Ik spreek Engels')
    .catch(err => {
        console.error(err);
    });
console.log(res.text); // I speak English
console.log(res.from.language.iso); // nl

From English to Dutch with a typo:

const Translator = require('@danke77/google-translate-api');

const translator = new Translator({
    from: 'en',
    to: 'nl',
    raw: false,
    client: 'gtx', // t
    tld: 'cn',
});

const res = await translator.translate('I spea Dutch!')
    .catch(err => {
        console.error(err);
    });
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

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

const Translator = require('@danke77/google-translate-api');

Translator.languages['sr-Latn'] = 'Serbian Latin';
const translator = new Translator({
    from: 'en',
    to: 'sr-Latn',
    raw: false,
    client: 'gtx', // t
    tld: 'cn',
});

Does it work from web page context?

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