google-translate-promise

Google Translate API, Node.js module with Promises flow

Simple client for Google Translate API.

Usage

const GoogleTranslate = require('./index');
const API = new GoogleTranslate({API_KEY: 'xxxxxx'});

API.translate('Hello world!', 'en', 'sv').then(res => {
	console.log(text); // Hej världen!
});

Options

This module has some default options:

const options = {
	API_KEY: process.env.GOOGLE_TRANSLATE_API_KEY || '',
	URL: 'https://www.googleapis.com/language/translate/v2',
	throttle: 500,
	timeout: 5000
};

What they do:

• API_KEY is your private key to acess the API. You can get one here.
• URL you should not need to change this.
• throttle defaults to 500ms, and is there to avoid too many requests per second. Value must be in ms.
• timeout if the request takes longer than the timeout the Promise will be rejected. Defaults to 5 seconds. Value must be in ms.

You can pass otpions to the module in the constructor, or using .setGlobalDefaults method.

If the nostructor has no options, the instance will use the global defaults
