Debugging

Node inspect

Node.js version >= 6 have an inspector feature enabled as default.

To start debugging, run pump.io with the --inspect flag

node --inspect bin/pump -c pump.io.json

Next, open “about:inspect” in an Chromium-based browser, if you don't like Chromium you can use the CLI inspector to debugging.

node --inspect bin/pump -c pump.io.json

and in other terminal

node inspect localhost:9230

The 9230 is the port of forked processes.

Node inspector package

Debugging in Node.js version =< 5 can be done via the Node Inspector https://github.com/node-inspector/node-inspector

node-debug pump

If you have problems with cluster mode you can try setting the child processes to one

"children":  1,

Also, you can try this patch https://github.com/e14n/pump.io/pull/1119 if the error persists.

Any Blink-based browser should work to connect to the debugger on http://127.0.0.1:8080/?ws=127.0.0.1:8080&port=5858

Wait for the fork and switch to the child process http://127.0.0.1:8080/?ws=127.0.0.1:8080&port=5859

Node debug

Alternative in Node.js version =< 5 is to use node debug

node  bin/pump -c pump.io.json
Debugger listening on port 5859

and then in a different window:

node debug localhost:5859
