Language Translator

A language tanslator which uses caching and smart pre-caching to improve efficiency of application.

Translate API

A smart API which not only translates the text given by the user in desired langaugae but also caches the previous results to reduce the response time .

Deployment

If you dont have Redis installed ,install it with this link . After that it would be ready to use on your localhost:3000

      npm install
      node index.js

Design

Caching :
A user enters the text to be translated . It get stored in cache . So next time if the desired result is found in cache the api does not get hit .

Smart Pre Caching :
Suppose a User demands a text to be translated in Hindi . Web Server automatically stores the result in Urdu , Marathi , Gujrati , Punjabi .
Thus saving the response time for the User. (Refer Map.js)
