Bug example for Vite and import.meta.url

Explanation

Vite fails to build library from node_modules where there is a new URL('.', import.meta.url) expression.

I also made a specific lib: lib_importmetaurl_dot.

Actually this lib is just an example and a test to check that import.meta.url is resolved correctly in userspace and in a lib too.

Example: main.js

Lines 4-5 are about local new URL('.', import.meta.url) usage. Comment them out to avoid local new URL invocation.

Lines 7-9 are about lib new URL('.', import.meta.url) usage. Comment them out to avoid imported new URL invocation.

Desired behaviour

To run in dev mode without errors. To compile without errors.

Now it shows such error in dev mode:

Uncaught TypeError: Failed to construct 'URL': Invalid URL
    at getDotRelativePathname (index.js:2:45)
    at main.js:8:15

Error is in imported usage. Lines 4-5 works ok and commenting out lines 7-9 removes the error.

And such error during build:

vite v2.8.6 building for production...
✓ 2 modules transformed.
[vite:asset-import-meta-url] EISDIR: illegal operation on a directory, read
file: /Users/user/tmp/vite_importmetaurl_dot/main.js
error during build:
Error: EISDIR: illegal operation on a directory, read
error Command failed with exit code 1.

Build

Vite pipeline

yarn dev - run vite in dev mode yarn build - build with vite

Webpack pipeline

yarn webpack - build with webpack yarn serve - serve dist folder to see webpack result
