A harness for starting a node app and recording performance.
Installation
$ npm install -g performance-harness
Running
$ node-perf run [--out=<path>] <script>
This will run the given script but wrap it in memwatch and a profiler. You can cause a heap dump to be taken by signalling SIGALRM. The internal node process running your code can be exitted by signalling SIGUSR2.
Providing --out will dump the report into the given path rather than ./out.json
The script provided should be the usual entry point into your application that you would run with node <script>.
$ node-perf view <json>
This will start a webserver on port 3000 and expose an html interface to view the results stored in the report json.
