Problem with environment variables and @snowpack/plugin-webpack

[ralphtheninja]

Using environment variables like:

const { SNOWPACK_PUBLIC_API_URL } = import.meta.env

works great during development, but I run into problems when building out with @snowpack/plugin-webpack.

I have put together a sample application that shows the problems here: https://github.com/ralphtheninja/snowpack-test

Any input is greatly appreciated. I thought it would be just enough to add the plugin, but maybe I'm missing some configuration?

Thanks @ralphtheninja for reporting the issue. I was able to reproduce it. The import.meta object has no .env property when running snowpack build. I also confirmed that everything works as expected when disabling the @snowpack/plugin-webpack plugin

I'll create an issue for prioritization. Next step would be to create a test in test/build to reproduce the error. Maybe test/build/html-environment-variables) might be a good starting point? Would you like to give that a go and start a pull request with a failing test?

FYI: You are currently using snowpack 2.8.0 in your test app, currently the latest version is 2.10.1. Upgrading does not resolve the problem though.

Good catch. I was sloppy there. I'll remove the package-lock in the test repo app as well and we can use this to test later on, once fix is out.

Do I mark this as answered now?

I'll give it a go. How hard can it be right? :) I might have some questions on setting up dev env for snowpack. I'm super new to the project. Are there any links to dev information, starting pointers, wiki etc?

I can confirm that downgrading @snowpack/plugin-webpack to 2.0.4 works.
