Describe the bug

Snowpack doesn't resolve dynamic imports:

import { library, icon } from '@fortawesome/fontawesome-svg-core';

const getIcon = async ( { icon: iconToFetch } ) => {

    const { [ iconToFetch ]: importedIcon } = await import( `@fortawesome/free-brands-svg-icons/${ iconToFetch }.js` );

    library.add( importedIcon );

    return icon( importedIcon, { classes } ).html

}

( async () => {

    const html = await getIcon( { icon: 'faFacebook' } );

    document.body.innerHTML = html;

} )();

Throws Uncaught (in promise) TypeError: Failed to resolve module specifier '@fortawesome/free-brands-svg-icons/faFacebook.js'

To Reproduce

Reproducible example: https://gist.github.com/jaschaio/321e794e7f8fb15d4bf9dfa0da46656c

Expected behavior

I would expect snowpack to notice the dynamic import, and replace the module identifier with the build output directory.

This is more likely to be related to esbuild rather than snowpack. Here is some discussion going on evanw/esbuild#700

TL;DR dynamic imports isn't something esbuild gonna support out of the box

This does seem to be a bug; thanks for filing! Will investigate.

It seems that snowpack won't resolve the path when dynamic import has a variable in it.
Any update?

This seems related to #2861, right?

Ah, right! This feature will solve the problem.

@drwpow I think this can be closed as a duplicate.
