How can I deploy an asp.net core website without requiring nodejs on the server?

Question

I am deploying my first asp.net core website. We are using NPM to manage packages from a dev perspective, but I was not under the impression that would make node js a requirement on the server hosting the website?

Right now, I'm getting "InvalidOperationException: Failed to start Node process" if I try to run the website. In an effort to keep the server as lean as possible, I would prefer not having node js on there. Plus, I have a concern it will try to update / download packages at runtime rather than include them when I deploy (from Visual Studio 2017 deploy to file option).

NPM is a package manager written in Javascript. You will have to ditch that dependency — itsundefined

I know we're using NPM to manage our dependencies, but can't find a way to still manage dependencies with NPM without requiring NPM / Node on the server side. A bit like when using NUGET to manage dependencies, I don't need anything around nuget on the server. — David

I don't know much about .net core, so forgive my ignorance, but is part of your deployment process to npm install ? Is it possible npm install is trying to run at every single start? I would also think that you don't need NPM to run your website. Especially if these are all client side dependencies. — Cody Geisler

I have no refereneces to node or NPM in my startup code. NPM is required to deploy, to get any packages missing, but I'm not calling it server side. Once deployed, I'm expecting everything it needs is included in the deployed files. — David

well you will have to install node then. It is less than 40MB so you are gonna be fine. — itsundefined

The feature that is causing this problem is "Server Side Rendering". It can be disabled by removing:

@addTagHelper "*, Microsoft.AspNetCore.SpaServices"

From Views/_ViewImports.cshtml

See this stack SO question for more details.
