// if you have stumbled upon this file because you have some kind of import
// error then you probably need to know what this is all about.
//
// the runtime/Client should remain agnostic to the environment it is loaded in.
// this is because we run the Client in both socket and in nodejs environments.
//
// this means that Client (or anything that Client imports) should not depend on
// any socket library that requires the socket runtime
//
// _some_ socket libraries are compatible with nodejs and can be imported but
// most cannot.
//
// you should make Client accept dependencies via the config so that compatible
// deps can be injected during Client instantiation, rather than being imported
// directly. and use `import type` to avoid importing the actual implementation.
//
// see what is being done for the Buffer, Encryption, NAT, network
//
// see src/cli for how the client is loaded from nodejs see src/gui/workers for
// how the client is loaded from a worker
//
// if you _really_ think the import should work, then you can add to the list of
// resolve.alias below.
