First time user here - I managed to download a flow from the flows.nodered.org library: https://flows.nodered.org/flow/54bea677f001eb07b2f68171fab028d4
I see it depends on some unknown nodes, like 'ui_button', 'ftp in',...
I go to the node palette install tab and do a search for 'ui_button' and 5 modules are available. When I type a search of 'ftp in', 8 modules are available.
How do I find the right module that contains the nodes marked unknown in this flow?
Shouldn't the dependencies be listed in the flow library page for this flow?
What steps am I missing to make the nodes recognized in the library flow?
Welcome to the forum @filipmu
It says in the text on that page that it needs node-red-contrib-ftp and node-red-contrib-image-tools, which you can install using Manage Palette in the node red menu. If it needs ui_button then it should have said that it also needs node-red-dashboard, which includes the basic ui_ nodes.
You can use the rather well hidden Flow Inspector to see what nodes are in a flow.
That can certainly be useful, but can often be confusing. For example, in this case it suggests half a dozen possible ftp nodes and several different dashboards.
Thanks for all the info - this is helpful. It's too bad the flow library doesn't make requirements mandatory, or better yet - the library names should be recorded in the flow json so that its more or less self-contained rather than depending on someone documenting it.
Hhm... I didn't know that existed either!
What is the navigation route for users to find the Flow inspector?
I've probably missed it, but I didn't find any links to it from Documentation : Node-RED
It was announced quite a while ago, can't remember the details I'm afraid.
New thing: Flow Inspector - General - Node-RED Forum (nodered.org)
I see in that thread that @cymplecy has already suggested a menu link for users to access the function.
Probably needs someone to submit a PR to the docs.
