google-translate-api

A free and unlimited API for Google Translate :dollar::no_entry_sign: 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 Setting client="gtx" seems to work even with outdated token, see this discussion for details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.

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 ([ ]):

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

    });
console.log(res.from.text.value); // I [speak] Dutch!

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