I am testing Dashboard 2 to migrate my frontend. Among other things I try some nodes, which are developed for the new dashboard.
For example iframe, gauge-classic and flowviewer. The problem is that different from the standard D2 Nodes the additional nodes don't show anything.
In the log of the browser developement-tool are some messages:
No vue component found for ui-iframe, ui-gauge-classic, ....
I am not a frontend-developer and I think that some vue components are missing. I have no idea which vue-library is missing and how can I provide them. Perhaps I have to define some things in the settings-file to load something.
I am sure that you have an idea. Thx in advance.
Did you restart node-red?
Can you show us the node red startup log please? It should start with Welcome to Node Red. Copy/paste the text please, not screenshot.
Short my environment to understand the log (docker container and node with pm2 I hope you can read the log

p.s. It is my test-environment and there are some erors from my own function-node.
I can't see anything obvious wrong there.
@joepavitt can you suggest anything?
In my browser log I see such kind of messages for all additional components:
No vue component found for ui-iframe - falling back to ui-template index-CbOqRi22.js:231
What browser and browser version? Can you post the full browser log/errors? Have you tried reinstalling the nodes? Have you tried another device/browser?
I am using Chrome the current version and I also test Edge.
I restart the container with all components. I restart nginx and the whole stuff.
I can send my browser log but I think it doesn't help only a few standard-messages.
I delete my whole node_modules-directory and make a fresh npm install.
All frontend-devices available are tested with the same result.
The description of #938 would fit but don't help in my situation,
sorry

I assumed because of the time and date in his logs that he already tried that.
I don't see any errors in that log.
When you say nothing is showing do you mean in the editor or the dashboard?
Check the network tab in the browser and see if there are any problems.
Good point, well presented
@Roland Are you running any proxies on the nginx server? Or have Node-RED http admin settings configured? We've had issues in the past (which I thought we had resolved) around Dashboard being deployed in these environments.
@Colin Nothing is shown in the dashboard no gauge, no iframe, .. The space for the element is available but no content is shown.
If you mean the network-tab in the developement-console - 14 elements are loaded without any error (Http-Codes 101, 200, 304). I don't see no vue ressource (name containing "vue"), I don't know is that ok.
@joepavitt I use proxies on nginx, but I stop the nginx-container and open the application direct using the ip:port/dashboard with the same result.
When you talk about http admin definitions in the settings-file, I don't use it.
Which vue-libraries (vue, vuetify, ...) are necessary ? Can I load them in the settings-file or is there a -statement on client-side missing, but why do the original dashboard 2 components (table, form, text input, template ....) work nicely ?
Sorry for my rookie questions and thanks for your help
?
When third party nodes are installed, they write to the package.json
of the Node-RED install path, which tells Node-RED where the third party complied .js
files are to serve up for the Dashboard to read.
This is why we need the Node-RED restart, as NR isn't aware of the changes until this has been done. Dashboard parses that package.json
and looks for any third-party node entries, and the paths of their js
files, if it can't find the files there (or the entires aren't in the package.json
) we can only serve up a blank space.
Are you able to read the contents of the package.json
file for your Node-RED install? Maybe something has prevented that being written to?
First : Can you give me an example what will be written into package.json - I don't realize anything.
Second : Only an Idea. I work with two package.json files see example. These are the originals for the test-environment. I use this constellation for round about 15 container-environments.
The complete node_modules is in the first path. The first package.json is always the same.
The reason for that was an automatic handling of the application part and to reduce the backup-overhead. Because the relevant components without node_modules are separated in the second path.
I think this is no standard way.

An idea - when the process of the third-party nodes during installation expect their own entry for example "@flowfuse/node-red-dashboard-2-ui-iframe" in the package.json - they don't find it in my primary package.json, because they are defined in the second one. And then they make no entry.
I see you are using projects, @joepavitt the package.json file location is not in the same directory as flows file when projects are in use. I wonder whether anyone has tested this with projects. I don't use them.
[Edit] I got this wrong, the package.json file is in the project folder, not the .node-red folder, so perhaps this is the problem.
How are you installing the nodes? I thought that when using projects that it was the package.json in the .node-red folder that was used, but I may be wrong.
[Edit] Projects : Node-RED tells me that I am wrong, each project has its own package.json.
Yes @Colin you are right ( long story short
) Thx
Make it sense to test it - I can move the entries from the second one into the first and reinstall.
Just copy them from the second to the first (leave it in the second too) and restart node-red and see if it works. That may tell you whether this is the problem. It may have undesired side effects though, messing with package.json is generally not a good idea. Make sure you have up to date backups just in case.
