Proposal: Case Sensitive Dependencies

[kt3k]

Digging more and more in ESLint rules, i found some good ones which enforces good style and more readable code. This issue is for dependencies/case-sensitive rule - not fixable.

Suggested configuration.

{
  "dependencies/case-sensitive": "error"
}

This rule verifies that require("…"), require.resolve(…), import "…" and export … from "…" ids match the case that is reported by a directory listing.

On mac and windows, require works in case-insensitive way, but in case-sensitive way on linux. The case mismatches in module ids cause platform-dependent bugs. This rule detects them and enforces platform independent style.

This is a neat idea! I recall we had some performance issues with some rules that search the filesystem. I'll see if I can find the reference.

If your project has babel, it will warn you about naming problem. If you work on a UNIX machine, this will end up to be a problem during compilation (the OS is case sensitive on filenames). I think rule should be a must have.

Could be nice with a rule that just enforced that it was all lower case. That way a part of standard would also be to name your javascript files in lower case which I think would be nice.
