The collaboration of Nodemon and Redwood-Broker

I have been running Nodemon in my express app without any special configuration. In my package.json file, I only have the following:

"scripts": {
  "start:dev": "nodemon app/app.js"
}
...

Everything runs smoothly until I make changes and Nodemon attempts to restart. At that point, I encounter an EADDRINUSE error. Even after completely restarting, the same error persists.

To troubleshoot, I checked for other processes running on port 3001 (which is where Nodemon should run), and found output similar to this:

$ lsof -i :3001
COMMAND   PID    USER         FD   TYPE             DEVICE SIZE/OFF NODE NAME
node    54343    myUserName   11u  IPv6 0x1bdae98886f3261d      0t0  TCP *:redwood-broker (LISTEN)

Killing this process allows me to restart Nodemon, but the issue reoccurs whenever I modify files being watched by Nodemon.

Searching online, I found some references to redwood-broker, but no solutions yet. Has anyone encountered this problem with Nodemon?

My current setup includes:

Express 4.16.2

Nodemon version 1.15.1

2016 MacBook Pro with Sierra 10.12.6

Any assistance would be highly appreciated!

Answer №1

This particular issue seems to be affecting a small group of individuals. You may want to consider the following steps:

Step 1:

Execute the command: sudo pkill node

Step 2:

  1. Run: sudo lsof -i :5955

Identify and terminate the process running on the specified port by using its PID

  1. Enter: sudo kill -9 PID

We hope these suggestions prove useful in resolving the issue.
