Watcher raises error in dev mode

[gs-jdudulski]

I tried this:

npx eventcatalog dev or npm run dev on nodes 20.18.0 and 22.5.1

This happened:

Each change raises error:

[1] 15:08:21 watching for file changes...
[0] node:fs:1260
[0]   options = validateRmOptionsSync(path, options, false);
[0]             ^
[0] 
[0] Error: ENOENT: no such file or directory, lstat '/Users/jandudulski/eventcatalog/.eventcatalog-core/src/content/services/ServiceName/4913'

[0] }
[0] 
[0] Node.js v20.18.0

I expected this:

Reload server with changes applied

Is there a workaround?

Stop the server and start again

Anything else?

No response

Hey @gs-jdudulski,

This error happens to anything you do? Or only when you remove/delete something from your catalog?

[gs-jdudulski]

Anything, on regular edits in files

[carlosallexandre]

Did you try removing the .eventcatalog-core?

[gs-jdudulski]

Just did, still the same.

But googling deeper I figured out it's becuase of... neovim. When editing in anything else it's fine.

Edit: https://github.com/neovim/neovim/issues/3460 oh crap 🤯

[gs-jdudulski]

Every edit emits 3 events for me:

[0] events [
[0]   {
[0]     path: '/Users/jandudulski/eventcatalog/events/ProductDeleted/4913',
[0]     type: 'delete'
[0]   },
[0]   {
[0]     path: '/Users/jandudulski/eventcatalog/events/ProductDeleted/index.md',
[0]     type: 'create'
[0]   },
[0]   {
[0]     path: '/Users/jandudulski/eventcatalog/events/ProductDeleted/index.md~',
[0]     type: 'delete'
[0]   }
[0] ]

I simply add a check to watcher for delete event:

// IF directory remove it
if (type === 'delete' && fs.existsSync(newPath)) {
  fs.rmSync(newPath);
}

And it seems to work but discovered another issue - in neovim I got create event instead of update 🙃

edit: like here https://github.com/parcel-bundler/watcher/issues/98

@gs-jdudulski

I'm working in a refactor to watcher to handle more edge cases and your scenario is covered there. (PR #764)

This PR handle create and update event in the same way.

I merged the changes from @carlosallexandre into the main build, although I still need to merge tests from #764 into the prod build. @gs-jdudulski let us know if you still have issues, will close for now, feel free to re-open if you find any problems.
