Slowserver is a simple web app with an intentionally slow responding endpoint and a websocket echo and websocket pinger endpoint.

This can be useful for testing HTTP clients and proxies.

Also included is wsocat, a command line websocket client.

Use go install to install slowserver and wsocat.

go install github.com/jrwren/slowserver/...

In one shell run the server:

slowserver

Then run wsocat to connect to it:

wsocat ws://localhost:8080/ws-pinger
