Description

The reason for this is that this allows using environment variables in the browser with vite. Vite has a feature where all environment variables that have a VITE_ prefix are exposed in import.meta.env. And even in node.js, import.meta.env is a alias to process.env so i don't see any reason why ConfigProvider.fromEnv only supported process.env

Unfortunately import.meta.env is an es-module only feature, it doesn't work in CJS

[coffeeispower]

This is a difficult problem because import.meta is a syntax error when running in CJS for some f reason, i think we can do some weird hacks like dynamically importing another file using the import() function which just exports import.meta so it works for both EJS and CJS.

in 4.0 we'll be publishing a single ESM module given that now node LTS supports sync loading of ESM modules so it won't be a problem any longer

Until then, just copy the code and replace it with import.meta.env in userland.
