asset_hash plugin removes relative path specifier, breaking ES modules

[marcoms]

Expected behavior and actual behavior

ES modules don't allow module specifiers that don't have a slash as shown below:

Uncaught TypeError: Failed to resolve module specifier "chunk-3LNNNTUA-fcaa17b4.js". Relative references must start with either "/", "./", or "../".

This comes from my JS bundle which begins with:

import{a as z,b as se,c as Eo,d as G,e as je,f as ue}from"./chunk-3LNNNTUA.js";

But gets replaced with this by asset_hash:

import{a as z,b as se,c as Eo,d as G,e as je,f as ue}from"chunk-3LNNNTUA-fcaa17b4.js";

It's important the ./ is preserved as shown by the above error.

Hi @marcoms 👋🏼 not sure if this is going to help with your problem or it's even related, but just in case ...

Couple of days ago I raised this issue: #2530. The point is that the current JavaScript minifier (only in v4 branch, in master is already changed to Terser) relies on the Uglifier gem, which doesn't support well ES6 syntax. So maybe your problem is somehow related? This only applies if you are using the :minify_javascript setting of course. The :asset_hash extension is a different one, but since I got some different problems due to Uglifier maybe it's worth a try 🤷

Hello @marcoms 👋🏼

Could you please try running your site under current main branch?

 gem "middleman", git: "https://github.com/middleman/middleman.git"

We pushed some fixes in the last months, so maybe this is gone.
