Keep the flows running after closing the web browser

zouhir · 26 October 2023 06:27

Hi, can anyone tell whether it is possible to keep the flows running on the background after closing the web browser ? In my case, whenever I close chrome window node-red flows stop. Is there anyway to do that ? Same question for the command prompt where node-red command is running.
Thanks in advance.

That is not how Node RED works, all flows are running server side, they do not require a Web Browser, the browser is used to only edit the flows - Node RED, won't be Node RED otherwise, unless you are using Nodes that are poorly developed?

We need to see an example

Node RED is a Node application, so if you need to run it in a non-interactive shell (as it normally should be), use something like systemd

See:
https://nodered.org/docs/faq/starting-node-red-on-boot

systemd example
https://raw.githubusercontent.com/node-red/linux-installers/master/resources/nodered.service

EDIT
I should mention, I refer to systemd but for something like windows, NSSM is used

nssm.md

#### Running Node-RED as a service on Windows using NSSM

These instructions assume you installed Node-RED from an [administrator enabled command prompt](https://technet.microsoft.com/en-gb/library/cc947813%28v=ws.10%29.aspx) using the `npm install -g node-red` command to do so.

As an **administrator**, install nssm from [https://nssm.cc/download](https://nssm.cc/download)

And then from the directory where you installed nssm, run the commands

    mkdir c:\temp
    nssm install Node-RED "c:\Users\\"%USERNAME%"\AppData\Roaming\npm\node-red.cmd"

What OS and hardware are you running on? How do you start node red running?
