junie-explorer Worker pool error: ModuleNotFound resolving "./src/workers/loadEventsWorker.ts"

The worker pool errors are mixed with the final crash of bun.

See v2.6.1.

I'd be interested to know whether the workers work without error on Windows, and what the load time is compared to concurrency disabled, but this should provide a workaround to use the old sync code if its still failing.

I think the fundamental problem is that the worker script was specified as a .js file, but was actually a .ts file. I suspect that the module resolution works slightly differently in the Windows binary and this prevented it from resolving the file.

I elected to change the worker logic so that you can disable workers and use the original promise based code. Set the CONCURRENCY=0 environment variable, e.g.

CONCURRENCY=0 ./junie-explorer-apple-arm64

For Windows command line, I think this should be:

set CONCURRENCY=0 && ./junie-explorer-windows-x64

One downside of disabling the concurrency is that it no longer shows the load progress as it reads each directory. This appears to be an issue of how many promises get created and how that interacts with the console.log output. Likely something to do with macrotask and micro task resolution in the run loop.

After the initial "Reading logs, please wait..." message, you'll not see any output until its done, when all the log messages come at the same time. I tried plenty of refactoring but couldn't resolve this, at least for my logs. Smaller log sets might behave differently.

Many thanks for the updates!

Disabling CONCURRENCY worked for Windows 11. Loaded in 93 seconds.

Increasing concurrency to just 1 crashes Bun:

Reported as also failing in the same way in the Apple Arm64 binary, which works fine on my own system.

Should be fixed in https://github.com/dmeehan1968/junie-explorer/releases/tag/v3.5.0
