node-clinic
Install
npm install -g clinic
Getting started
As a first step, run the clinic doctor:
clinic doctor -- node server.js
Then benchmark your server with wrk or autocannon:
wrk http://localhost:3000
autocannon http://localhost:3000
If you want to run autocannon or wrk as soon as your server starts listening you can
use the --on-port option
# $PORT is the port the server is listening on
clinic doctor --on-port 'autocannon http://localhost:$PORT' -- node server.js
Finally shut down your server (Ctrl+C). Once the server process has shutdown
clinic doctor will analyse the collected data and detect what type of issue
you are having. Based on the issue type, it will provide a recommendation for
you.
Supported Node.js versions
Clinic relies heavily on Node.js core instrumentation available in later versions.
Currently the supported Node.js versions are ^9.4.0 and ^8.9.4.
