Package "path" not found when running with polyfillNode: true

[tzvc]

Hi there,

I'm having trouble using the node-built-in path module with snowpack. I understand that a special option is needed to polyfill node built-in for the browser, so I did:

...
installOptions: {
  polyfillNode: true,
},
...

but whenever I run snowpack dev I still get the following error:

[snowpack] ! installing dependencies...
[snowpack] Package "path" not found. Have you installed it?

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! myproject@0.1.0 start: `snowpack dev`

Any ideas ?

What you're seeing: You can't use "path" in your own code, since it's a Node.js built-in and doesn't exist in the browser. You can look for a equivalent package or polyfill on npm.

But, I think using --polyfillNode to polyfill your own imports isn't a terrible idea, especially for anyone migrating an existing app. Right now we're using a public node polyfill that we don't control, but we've considered forking it for different reasons. If we forked it, then we could build it in a way that snowpack dev could also use it.

Oddly, I just started getting this error in 3.1.1 in snowpack build whereas I don’t have it in 3.0.10 when using:

  packageOptions: {
    polyfillNode: true
  },

Oh, looks like the option was removed? https://www.snowpack.dev/reference/configuration

Ah, no, it’s still there but not in the sidebar index on that page: https://www.snowpack.dev/reference/configuration#packageoptions.polyfillnode
