Hi all, I'm having problems getting nodered to load after adding an external npm module. npm install -g ansi-to-html npm list -g /usr/local/lib ├── ansi-to-html@0.7.2 It looks like it's installed. I edited settings.js in my .node-red directory functionGlobalContext: { // os:require('os'), ansitohtml:require('ansi-to-html'), }, When I start nodered via systemd Dec 12 01:07:26 bbs Node-RED[1071764]: Error loading settings file: /home/nodered/.node-red/settings.js Dec 12 01:07:26 bbs systemd[1]: nodered.service: Main process exited, code=exited, status=1/FAILURE So I'm not sure what I'm doing wrong. It doesn't give any good reason for why it failed. Would appreciate some advice. Thanks,

You have an extra comma , at the end of the line you added. Remove it.

Does it remove that issue if you comment out that line and the comma on the line above?

Since that is the only line I added then yes, it works fine without it. Considering almost every other line ends in a comma, I don't think that is of any relevance in this case, however it works neither with or without it.

Actually, it works fine with the comma on the above line, since the above line is also commented out. Essentially, if I comment out the line I added then the function is empty. for shits & grins, I removed the comment from the os:require('os'), line and it works, including the trailing comma. So it seems to have an issue with me requiring ansi-to-html. Lacking any sort of meaningful debug message, I have no idea what the problem is. Did I miss a step or something?

Nevermind, i got it working. In the nodered-modules directory I did npm install --save ansi-to-html and it started right up. Ended up running it through strace and saw it was looking in the local directories so I was able to find what I needed from there,. Maybe this will help someone in the future.

For future reference, you can also avoid all this manual editing of settings.js & manual npm installation etc. Instead, simply add modules via the UI on a function node (the setup tab). Here is an article demonstrating this.

Now that would have been good to know. I'll maybe convert to this method.

So I tried with the solution mentioned above and I think I'm pretty close. I removed the entry in settings.js and in the function > Setup I entered ansi-to-html and used the variable ansiToHtml. Now, the output it changed but I just get a string of numbers. Please refer to Ansi to ascii or html which is what I was trying to do in the first place. So I'm not sure what is going on here. const ansitext = msg.payload; const Converter = ansiToHtml; const convert = new Converter(); const htmltext = convert.toHtml(ansitext); msg.payload = htmltext; How my payload looks like "27914910927915154109200205187...." So, again, appreciative of any assistance. I feel I'm close..
