Node-Red custom node_modules location

Question

I'm using node-red as embedded in my Express.js application like this https://nodered.org/docs/embedding. When embedded like this node-red cant load new nodes from npm.

Issue is that when defining custom user dir in settings.js, for example userDir: 'node-red-data/' Node-red adds loaded nodes to this folder inside node_modules.

So I have two node_modules folder:

myapp/node_modules => this is containing node-red
myapp/node-red-data/node_modules => this is containing node-red extra nodes

Some how node-red can't load modules in side myapp/node-red-data/node_modules

Is there any solutions?

Issue was on the settings file.

My setting in user dir:

var settings = {
    httpAdminRoot: '/admin',
    httpNodeRoot: '/ap',
    nodesDir: '/nodes',
    flowFile: "flows.json",
    userDir: './data/'
}

Right setup:

var path = require('path');
var dir = path.dirname(__filename);
var settings = {
    httpAdminRoot: '/admin',
    httpNodeRoot: '/ap',
    nodesDir: dir + '/nodes',
    flowFile: "flows.json",
    userDir: dir+'/data/'
}

So adding static path to user dir and nodes dir makes it working
