myvariantjs

A NodeJS client for MyVariant.info web services

Demo App

You can view a basic web app demo which uses the myvariantjs lib.

You can also clone and start the demo app locally. Repo is here.

Developed enterly in Chrome. Mileage may vary in other untested browsers right now (sorry 'bout that, not enough hours in my day).

Intro

MyVariant.Info provides simple-to-use REST web services to query/retrieve genetic variant annotation data. It is designed for simplicity and performance.
