Install new nodes in NodeRed without internet connection

General
1

Good afternoon everyone!
I have an environment with NodeRed and I need to install the packages: node-red-contrib-opcua and node-red-contrib-s7.

Is it possible to add these modules in the environment without internet? as I can't access manage pallete.
I would need help and know how to do this.

Regards

Tadeo

I don't know ho to do this manually with the files, like from a local drive/USB.
But assuming that the host node-red is running on has some kind of networking capabilities, the easier method would be to bring (mobile) internet to the site for the time you do the install....use a mobile phone as Wifi-hotspot maybe?

You can load individual .tgz (i.e. package archives) into Node-RED using the upload button in the install tab of the palette manager:

You might or might not have this feature depending on your installation (e.g. FlowFuse community edition does not have this feature).

Thanks for both!
The server where NodeRed is running does not have Internet access (for security reasons), so it could not perform this task.
But I can upload package! Now my question is if this type of node (node-red-contrib-s7) I can install only the first package or I have to install all the ones that are appearing in node_modules.

you can get the .tgz for any packages by first looking at https://registry.npmjs.org/node-red-contrib-s7

That gives you a .json and somewhere under versions:

you can the .tgz file for your package.

Another alternative is to setup another machine that does have internet access with exactly the same OS and version with the same version of nodejs and the same node-red installed in the same way. Then install the node on that machine and copy the whole .node-red folder (or wherever your node red user directory is) to the production machine.

I have tried in a similar environment, I installed Node-RED, disconnected the PC from the network and I can't load the .tgz. I get the following log:

I then tested by connecting the PC to the network and the installation ran successfully.
What other way could I try?

The tgz does not contain all the dependencies so tries to get them from NPM - so you have the same issue as before.

I wrote a reply on a potential solution some weeks back - i will see if I can find it.

Here you go: Can't install node-red-contrib-chart-image - #4 by Steve-Mcl

Perhaps you will try this and let us all know (unlike the OP in the linked thread who never bother to?)

I have managed to install the node-red-contrib-s7 package as you specified, but the same has not happened with node-red-contrib-opcua. The latter took longer to compress and then gave me an error on installation.
