zstd decompression no longer works in a NextJS project since 7.6.0

[chrisburr]

I have a NextJS project which uses JSRoot in a static export of the site. Since #274 was merged zstd decompression no longer works.

In the browser console I see:

GET http://localhost:3000/_next/static/chunks/base/zstd.mjs
Loading module from “http://localhost:3000/_next/static/chunks/base/zstd.mjs” was blocked because of a disallowed MIME type (“text/html”).
Loading failed for the module with source “http://localhost:3000/_next/static/chunks/base/zstd.mjs”.

Looking more closely I see this is caused by a 404 error and zstd.mjs not being found. Looking at the code it's not clear to me how import(/* webpackIgnore: true */ './base/zstd.mjs') is supposed to work though I'm a bit out of my comfort zone.

How you deploy JSROOT? Are you using node.js tools?

Maybe it is mistake in JSROOT to specify /* webpackIgnore: true */ for zstd.mjs and lzma.mjs.
It can be that because of such specifier these modules are not correctly deployed.

Can you try to copy modules/base/zstd.mjs and modules/base/lzma.mjs to your _next/static/chunks/base/ folder by hand?
From my side I will remove such specifier from source code.

Sorry for the delay in getting back to you, I ran into #318 and got very confused about what was going on 😄

I have jsroot listed as a dependency in my package.json file.

I've applied 8239a88 with patch-package and it's fixed the issue. Thanks a lot for the prompt response.

Grate!
I had other zstd-related issue, which is also fixed now in master.
I will try to provide patch release soon.

Resolved in 7.7.3 release
