File not found in Node.js

[lkwinta]

When loading jsroot in node project we get following errors:

We can confirm that those files are indded missing in files downloaded by npm.

Error pops when starting node project using npm run start.

In which context you are using jsroot with node.js?
Can you provide reproducer?

File modules/base/index.js.map not exists - and never exists before.

We use it as a part of this project: https://github.com/yaptide/ui (basically this is an web UI for particle transport simulators, like Fluka).

Here is some basic documentation for developers (how to clone and run the UI): https://yaptide.github.io/for_developers/frontend/for_developers/

I have python3.13 as default and your project complains when I try to call npm run start.
Is there simple way to let use it older python version - I also have python3.11 installed.

And may be you can deactivate usage of source map as it discussed here:

https://stackoverflow.com/questions/70599784/failed-to-parse-source-map

JSROOT not aware about this at all.

You can also try a docker build as documented here: https://yaptide.github.io/for_developers/frontend/for_developers/#building-the-app-using-the-dockerfile

Thanks for notice about python 3.13 - that is worth to check on our side

I am not sure how to use modified version of your project in docker.

Can you provide me Dockerfile which uses dev branch of JSROOT and only builds your application without running it?

[grzanka]

In principle you can clone the repo, then adjust the Dockerfile like this:

		"jsroot": "^7.8.2",
+		"jsroot": "git+https://github.com/root-project/jsroot.git#dev",

But that builds and run the application.

Maybe it would be faster for me to fix the Python 3.13 issue. Are you working on Linux or some other system ?

[linev]

Usage 7.9 branch of JSROOT in package.json shows no error for me.
docker build -t ui . runs normally for me.

If I trying to use dev branch I got error:

 Module build failed: UnhandledSchemeError: Reading from "node:worker_threads" is not handled by plugins (Unhandled scheme).

How I can "hide" this node:worker_threads which is used only when running JSROOT inside node.js.

[linev]

And I am using Linux

The error in this issue pops when running our project with npm run start command, not docker. Sorry for not specifing it at the issue.

[linev]

Maybe you can try to find commit in JSROOT repository which made problem?

Just bi-section between 7.8 and 7.9 releases.
I personally have no idea that happens.

[linev]

Is any news here?
Did you try to identify at which moment between 7.8 and 7.9 releases problem appear?
