Language Translator Node.js

The IBM Watson™ Language Translator service provides an Application Programming Interface (API) that lets you identify the language of text, and then use a custom business domain to translate the text from one supported language to another.
You can translate either by letting the service identify the source language or by selecting a source language and then by selecting a target language, and a business domain. Domain translation is linguistically targeted these business domains:

The News domain - targeted at news articles and transcripts, it translates English to and from Arabic, Brazilian Portuguese, French, Italian, or Spanish. It also translates Spanish to and from French.
The Conversational domain - targeted at conversational colloquialisms, it translates English to and from Arabic, Brazilian Portuguese, French, Italian, or Spanish.
The Patent domain - targeted at technical and legal terminology, it translates Brazilian Portuguese, Chinese, or Spanish to English.
