Can not resolve sub-module

[ije]

the screen-shot is from:

yarn add vanillajs-datepicker
echo "export { default } from 'vanillajs-datepicker/js/i18n/locales/cs';" > entry.js
esbuild entry.js --bundle --format=esm --outfile=bundle.js

esbuld 0.11.9

i understand esbuild will respect the exports in package.json, but maybe we should support the native path as well.

Closing as by design. Node doesn't allow you to access this either, and has the same error message:

$ node -p "require.resolve('vanillajs-datepicker/js/i18n/locales/cs')"
internal/modules/cjs/loader.js:438
      throw e;
      ^

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './js/i18n/locales/cs' is not defined by "exports" in node_modules/vanillajs-datepicker/package.json

This is a result of esbuild following node's specification for the exports field. This package uses the import path vanillajs-datepicker/locales/cs not vanillajs-datepicker/js/i18n/locales/cs:

$ node -p "require.resolve('vanillajs-datepicker/locales/cs')"
/Users/evan/Desktop/foo/node_modules/vanillajs-datepicker/js/i18n/locales/cs.js

You have to import this using the path vanillajs-datepicker/locales/cs instead.

i see, thanks for your replay!
