Request Header Parser Microservice

Get a browser's IP address, preferred languages, and system information.

How it Works

This microservice uses Koa to retrieve request headers and, along with koa-router, serve requests.

How to Use

app.js exports a Koa app. Koa apps have an app.listen() method that is identical to Node's http.Server.listen().

Import app.js and call app.listen() to start up the microservice.
