For example In other words, Can we able to run on different ports The application running in http://127.0.0.1:1880/ and the other in http://127.0.0.1:1881/

That has already been answered. By giving each instance its own userDir (-u) they each have their own settings file and catalogue.json file.

When running multiple instances, you need to use different workspaces (default is .node-red in your user dir) using the -u DIRECTORY parameter when starting Node-RED (depending on how you start it, of course). In doing so, you can modify the port in the settings.js of each instance's workspace. Alternatively, you can specify the port using the -p PORT parameter. Also, if you search the forum, there are different solutions to this: Search results for 'multiple instances' - Node-RED Forum

Alright Got it, What are the steps to point to the JSON file locally using HTTP localhost for example; I have to create it like this; http://localhost:1880/catalogue.json'. This isn't working and the catalogue.json file is in this location C:\Users\user.node-red\catalogue.json please find the screenshot for reference [image]

Can you open http://localhost:1880/catalogue.json in a browser? If not, then node-red cannot either.

If you are running multiple instances on multiple ports then you may need to change the catalogue port also... unless they all share that same one. - but yes must have access in e first place.

I'm getting this error [image] That means its not pointing to catalogue.json file I'm not able to get the catalogue.json content. So what is the correct path to point catalogue.json file - Considering and running single node application My catalogue.json file is in this location C:\Users\user.node-red\catalogue.json What is the correct path I can give it in settings.js PFA screenshot of settings.js file [image]

If you want Node-RED to load a catalog from http://localhost:1880/catalogue.json then you need to do something to set that up http endpoint. The palette.catalogues setting assumes your are providing URLs. One option to make that catalogue available would be to use the httpStatic setting - that can be used to tell Node-RED to make a particular directory available on its http server. So you could do: create a directory to contain your static served files - such as ~/.node-red/static copy you catalogue.json into that directory set the httpStatic property in your settings file to the full path to that directory - c:/Users/user/.node-red/static/ (check I've got that path right...) restart Node-RED

I have given, but still, it didn't work out Please find screenshots below [image] [image] [image]

the httpStatic property should be set to the directory containing catalogue.json - not the file itself.

[image] knolleary: directory containing You mean I just need to give for httpStatic in settings.js file as below httpStatic: 'C:/Users/usre/.node-red/static/'

Yes. Sorry, I see I got my instructions wrong previously. I have edited that reply to correct it.
