Websocket App publish crashes

[joeyshipley]

When attempting to call app.publish('broadcast', 'test message'); after the app.ws is setup causes the application to silently crash/die.

[joeyshipley]

Exploring this a bit, I found that updating nanoexpress.js in the const _app creation that updating the function setting seems to not crash this.

_app.publish = (channel, message) => app.publish(channel, message);

I am still having issues with my channels/subscriptions, so I'll keep poking at it before trying a PR out.

[joeyshipley]

After updating my local version to use the passthrough for the publish method, I was able to get it working without issue. I can provide code/examples if needed.

If it helps, here's a PR > https://github.com/nanoexpress/nanoexpress/pull/100.

If possible, please, add example.

Thanks

[joeyshipley]

Happy to. Thanks for addressing it so quickly. :)

I have a local project that has a front end listening to the channel and it receives messages after the change. It's much larger though, not sure how to easily share end results past the server staying alive.

Hrm, I'm still on LTS. I'll pull that node version and see on my end. -- update 13.14.0 worked for me also. I'm going to poke around and see if I can't make it fail again locally.

[joeyshipley]

I updated example repo to specifically point to the patch, I forgot to do that earlier. I'll keep poking around, but if you could try that again it would be helpful.

[joeyshipley]

Sorry, I'm learning some of this. How did you pull down v2.0.3?

[dalisoft]

It’s locally, just increased patch number

[dalisoft]

LTS maintenance mode comes later as currently I don’t have enough time to migrate, move to separate branch

[dalisoft]

I catch another bug while testing recently, so much bugs and so less time

[joeyshipley]

Was thinking it might be a build/compile issue, but building from the fix repo keeps the code inline and worked for me again. Going to think about this and see if I can come up with a different direction to reproduce locally.

Do you have a different example, I can try that also if you do.

[dalisoft]

Please look at new branch docs/example-pub-sub, error while running as described here.

Can be run with this command NODE_ENV=development node --trace-uncaught examples/pub-sub.js

[joeyshipley]

Oh, good catch. I wouldn't have thought to throttle the memory and test it. At any rate, thanks for work on all of this.

[dalisoft]

Thank you for bug-report. Of course, i didn't throttled memory, MS VSCode and Apple AppStore did it for me 😆
