express-downstream v0.1.4

Express Downstream

A simple server which prints out information about the request including the path, method, headers and environment.

It is often used as a Docker container when setting up proxy configurations.

npm install
PATH_404=/404 PATH_500=/500 SCRIPT_NAME="" NAME='Hello!' PORT=8000 DEBUG=express-downstream node bin/express-downstream.js

With this setup, paths under /404 always return 404, paths under /500 return 500. Other paths return 200.

You can configure the following variables:

• PORT - port to bind to, default 80
• NAME - the heading of the page, default Express Downstream
• SCRIPT_NAME the path at which a 200 page should be returned, default ''
• PATH_404 the path at which express should always return a 404 page for any sub-path, if not specified, no 404 handler will be used
• PATH_500 the path at which express should always return a 500 page for any sub-path, if not specified, no 500 handler will be used
• DEBUG - can be express-downstream,express-downstream:debug for full debugging, express-downstream for lkey messages, or empty for no debugging
