Is it possible to add a dependency to a node.js version?

My upgraded node-red module requires node v10+ to be able to execute N-API threadsafe functions.

Is there a way that this can be specified in the package.json file to prevent users without v10+ performing the upgrade (for example via the palette) and failing with compile errors (from node-gyp)?

You can add an engines section to your package.json -

However, by default, that will only produce an advisory warning in the log. Strict checking is only done if the user has enabled it in their own npm configuration.

Worth remembering that Node 8 is no longer maintained (as of a couple weeks ago) so users should really be on Node 10 at least.

I notice that the node red docs suggest that V8 is still supported in node-red. Should that be amended?

Node-RED does still support being run on Node 8. That hasn't changed. But you'll also note it says it is going end of life 31st December 2019.

I've added engines section now to my node module, but I still didn't get the advisory message using node v8.12 and node-red v0.8.4.
