Nuxt.js: Nuxt generate hangs after completion

[peitalin]

I'm running into the issue where nuxt will hang after running yarn generate on a small site:

  nuxt:generate Destination folder cleaned +30s
  nuxt:generate Static & build files copied +29ms
  nuxt:render Rendering url / +3ms
  nuxt:render Rendering url /terms +53ms
  nuxt:render Rendering url /privacy +9ms
  nuxt:generate Generate file: /index.html +590ms
  nuxt:generate Generate file: /terms/index.html +78ms
  nuxt:generate Generate file: /privacy/index.html +40ms
  nuxt:generate HTML Files generated in 31.1s +4ms
[nuxt] Generate done

Nuxt hangs, so if i wanted to run something like yarn generate; yarn serve, yarn serve is never run.

Any ideas what may be causing this?

Shouldn't it be && @peitalin

@peitalin Are you using something like Firebase or similar that is opening a socket which keeps open?

[piyushchauhan2011]

Hmm, or maybe because of watchers ? https://nuxtjs.org/api/configuration-watchers/#the-watchers-property @florianwittmann

[florianwittmann]

Maybe we need a generateDone event/hook to be able to provide some function in nuxt.config.js for socket closing and other cleanup stuff?

[peitalin]

I'm not using anything with sockets at the moment; the sites a a landing page with basic JavaScript functionality.

Please attach some code example, so we can reproduce it @peitalin

It seems getting Firebase data in asyncData might cause nuxt generate to hang.

This glitch demonstrates the issue (I think): https://glitch.com/edit/#!/nuxtjs

Its asyncData code is:

asyncData: function(context, callback) {
  firebase.database().ref('/').once('value').then(function(snap) {
    console.log("Data from Firebase: " + JSON.stringify(snap.val(), null, 2));
    callback(null, snap.val());
  });
}

and runs: nuxt generate; ls -lht dist; echo Done

But "Done" never shows up!

I did a clean git clone, yarn install, yarn generate of my repo and the issue is no longer there.
