pid-terminator

Every so often, I get the following error: Error: listen EADDRINUSE 127.0.0.1:3000. This module allows to terminate a process(pid) associated with a localhost/port that is still running in the background even though the application was closed.For now, Mac only.

installation

global

npm install pid-terminator -g

local

npm install pid-terminator --save-dev

usage

you can terminate one or more processes:

$ pid-terminator PORT_Nº [PORT_Nº[...]]

you can also call it from a npm script in you package.json. Before running the node application, pid-terminator will verify if a process associated with localhost:4000 is already running and terminate it if it does.
