Worker with import is failing to build since alpha.5

[kalvenschraut]

Describe the bug

I am going through the process of a major refactor into a monorepo for my company's code base and ran into the below issue when running vite build on alpha.8 and later while it builds successfully on alpha.7. I don't have a minimal reproduction yet, may be easier for me to debug off my codebase and attempt a PR if possible, but wanted to make an issue to see if the output was helpful or if I could be given direction to look into this issue.

Odd alpha.7 stopped working for me now and I had to roll back all the way to alpha.4

[patak-cat]

After:

• feat: non-blocking esbuild optimization at build time #8280
  that first appeared in vite@3.0.0-alpha.5, the error:

Error: Unexpected early exit. This happens when Promises returned by plugins cannot resolve. Unfinished hook action(s) on exit

is a sign that we are waiting for rollup to finish processing a file before starting to optimize dependencies, but the file processing is blocked by the deps itself. This shouldn't be the case, a minimal reproduction would be very valuable. If not, if you can debug, this is the new logic that is affecting you:

vite/packages/vite/src/node/plugins/optimizedDeps.ts

Line 73 in 408e5a7

function runOptimizerWhenIdle(config: ResolvedConfig) {

And here:

vite/packages/vite/src/node/plugins/importAnalysis.ts

Line 618 in 408e5a7

delayDepsOptimizerUntil(config, id, () => request)

You can set optimizeDeps.devScan: true, but it would be good to avoid it as we are trying to deprecate/remove the scanner in v3.

Are you using workers in your project? Check this part if that is the case:

vite/packages/vite/src/node/plugins/optimizedDeps.ts

Line 46 in 408e5a7

export function registerWorkersSource(

[kalvenschraut]

Thanks for the information!

I found out removing the worker import causes the build to succeed, and each build after that will continue to succeed until I remove everything under node_modules/.vite. I think this was the reason I was confused what version introduced the issue.

[patak-cat]

Yes, you can also run it with --force that will clear the deps cache so you are always testing cold start. Looks like the registerWorkersSource scheme isn't working correctly. If you can create a minimal repro using a worker, I can debug it. Thanks! Or let me know how I can help if you'll try to debug it yourself.

Experiencing the same thing on 2.9.10

@SebiTalent04 the error you're seeing doesn't seems related to this issue. Would you open a new bug report with a minimal reproduction? Thanks!
