Webpack warning of circular dependencies inside workerHelper.js

[codeart1st]

WARNING in [entry] [initial]
Circular dependency between chunks with runtime (main, pkg_snippets_wasm-bindgen-rayon-7afa899f36665473_src_workerHelpers_js, src_worker_js-pkg_snippets_wasm-bindgen-rayon-7afa899f36665473_src_workerHelpers_js)
This prevents using hashes of each other and should be avoided.

Current versions of webpack don't seem to like the recursion inside workerHelper.js

      // Self-spawn into a new Worker.
      //
      // TODO: while `new URL('...', import.meta.url) becomes a semi-standard
      // way to get asset URLs relative to the module across various bundlers
      // and browser, ideally we should switch to `import.meta.resolve`
      // once it becomes a standard.
      //
      // Note: we could use `../../..` as the URL here to inline workerHelpers.js
      // into the parent entry instead of creating another split point -
      // this would be preferable from optimization perspective -
      // however, Webpack then eliminates all message handler code
      // because wasm-pack produces "sideEffects":false in package.json
      // unconditionally.
      //
      // The only way to work around that is to have side effect code
      // in an entry point such as Worker file itself.
      const worker = new Worker(new URL('./workerHelpers.js', import.meta.url), {
        type: 'module'
      });

I kind of suspect that this is expected and nothing to worry about. I mean this circular dependency is in fact by purpose.

If it's intendet and there are no ways to ignore this warning in the library itself, the issue can be closed.

Currently to get rid of the message I added the following to my webpack config.

  ignoreWarnings: [
    /Circular dependency between chunks with runtime/
  ],

[maxammann]

ignoreWarnings: [ /Circular dependency between chunks with runtime/ ],

This actually ignores all kinds of these messages. I would not do this as you might miss proper issues!

I'm still investigating whether there is a way around this. I'm currently creating a library with a similar goal and experience the same issue.

[RReverser]

It is intended, yes, hence feel free to close. Side-note: as a Ukrainian, I'm currently not super-inclined to look at code and will be slow to respond to issues.

Close it now as a kind of documentation.

OT: I wish all ukrainian people and the russian people which were arrested because of demonstration peace in the world. ☮
