Denmark

Node.js webserver for benchmarking and testing downstream infrstructure that deals with node.js services

Why?

This allows you to test how your downstream infrastructure is able to handle the load of your expected application in areas such as payload and latency.

Install

npm install denmark -g

Usage

bash> denmark

This will start a clustered webserver listening on port 3000 by default

Url Configuration

http://{host}:{port}/?latmin=100&latmax=1000&paymin=1024&paymax=2048

This url will generate a response from a server with a random latency between 100ms and 1000ms that has a random payload size between 1024kb and 2048kb

http://{host}:{port}/?latmin=100&paymin=1024

This url will generate a response from a server with 100ms latency and 1024kb payload size
