How to install node types?

General
1

Hello,

I'm new to node-red, and I need help with installing node types.
When I run the project it says:

Flows stopped due to missing node types.
sf:3f24e8e108a6d3cc
sf:827ff8967a4e86f6

And I have them in separate folder, in main project folder (.node-red), in package.json I have included them(setworkmode and uimonad).

{
    "name": "node-red-project",
    "description": "A Node-RED Project",
    "version": "0.0.1",
    "private": true,
    "dependencies": {
        "node-red-contrib-bigexec": "~1.3.3",
        "node-red-contrib-modbus": "~5.23.1",
        "node-red-contrib-ui-contextmenu": "~2.0.1",
        "node-red-contrib-ui-led": "~0.4.11",
        "node-red-contrib-ui-multistate-switch": "~1.2.3",
        "node-red-dashboard": "~3.1.7",
        "setworkmode": "file:../subflowModules/setworkmode",
        "uimonad": "file:../subflowModules/uimonad"
    }
}

Inside those 2 folders(setworkmode and uimonad) are index.js, package.json and subflow.json that former colleague has created.

And in CMD it says:

13 Apr 12:16:20 - [info] Waiting for missing types to be registered:
13 Apr 12:16:20 - [info]  - sf:3f24e8e108a6d3cc
13 Apr 12:16:20 - [info]  - sf:827ff8967a4e86f6```

Have you run npm install since adding them to package.json? You need to do that to get npm to create the necessary symlnks from /.node-red/node_modules to where the nodes are.

I have, but i get this:

C:\Users\Marko>npm install
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path C:\Users\Marko/package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'C:\Users\Marko\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Marko\AppData\Local\npm-cache\_logs\2023-04-13T10_18_48_898Z-debug-0.log
4

I'm not 100% sure where files need to be located.

5

You need to run npm install in the same directory as your package.json file - .node-red

6

I did it like this:

C:\Users\Marko>npm install C:\Users\Marko\.node-red

removed 151 packages, changed 2 packages, and audited 164 packages in 4s

20 packages are looking for funding
  run `npm fund` for details

7 vulnerabilities (4 moderate, 3 high)

To address issues that do not require attention, run:
  npm audit fix

To address all issues, run:
  npm audit fix --force

Run `npm audit` for details.

But now I don't have any other nodes in palette except node-red and setworkmode, and more of the nodes in the project are red line dashed

7

That is not what I said to do.

You should run npm install from in the directory C:\Users\Marko\.node-red

cd C:\Users\Marko\.node-red
npm install
8

I did it like that now, but I'm still missing uimonad node in palette

What is in package.json?

In uimonad package.jason is:

{
  "name": "uimonad",
  "version": "1.0.0",
  "description": "Ensure UI text reacts to errors and fetch prompts.",

  },

    "node-red-dashboard": "^3.4.0"
  }
}

As you can see, that is messed up. It may have been the incorrect npm install that you did earlier that caused that. Fix that, then I may be wrong, but I don't think it is a good idea to put the linked nodes under the .node-red folder, I think I had problems doing that at some point. Move them out to separate folders and remove those entries from package.json. Then to get the subflowmodules installed, go into the .node-red folder and run
npm install /path/to/subflowModules/setworkmode
and the same for the other one. Then restart node red.

12

If you are not sure how to fix package.json then delete it and the node_modules folder. Then restart node-red. It will complain that there are missing nodes. Install those again, which you can do from inside node-red, then manually install your nodes as described above and restart node-red.

Category changed to general as the post is not about "developing nodes" :grinning:

14

Could you explain to me from start, so 0, I just opened new project and I only want to install for example setworkmode node type, how do you do that? Things that I have are only folder setworkmode and inside are files:
index.js

 const fs = require("fs");
 const path = require("path");

 module.exports = function(RED) {
     const subflowFile = path.join(__dirname,"subflow.json");
     const subflowContents = fs.readFileSync(subflowFile);
     const subflowJSON = JSON.parse(subflowContents);
     RED.nodes.registerSubflow(subflowJSON);
 }

}

Where do I need to put that folder and what do I need to type and where? Step-by-step please, I'm just starting so I don't know much.

Firstly, do not manually edit package.json. If you have already done that then start again.

To install your node, in a command window, cd to your .node-red folder and, as I said above, run
npm install /path/to/your/node
then restart node-red.
I also said that I think I have had problems if the node is under the .node-red folder so it may be best to move it out of there.

Thank you soo much, it worked
