support for relative external path (--external:../../module.js)

[richardpramono]

I tried to exclude an external module which located at upper folder of the project location:
eg:
esbuild index.js --minify --external=../../sha256.min.js

but it says Invalid module name.

Yeah right now that only accepts module names, not file paths. That could be a feature to add.

What's your use case for excluding a file from an upper folder? Is it a package nested inside another package? Do you not have control over the outer package? Also: are you bundling for node or the browser?

My case is that I'm building a library that use sha256 library. But that external sha256 library is used by other project too, and I don't want to include it in the build.

But now I have found temporary solution: first, change the ../../sha256.min.js. into sha256.min.js, build it with external. Then find the filename, and add ../../ haha.. but it works now.. I hope you can add ../../ support in the external feature in the future..

Thanks~
