Build gets stuck after success

[MartinMuzatko]

Bug report

Version

Tested with 9.1 and 10.1

Steps to reproduce

vuepress build

This happens ONLY in this repository: [email protected]:MartinMuzatko/wire-up-your-front-ends.git or download from here: https://gitlab.com/MartinMuzatko/wire-up-your-front-ends

My other vuepress project builds fine, but since this project is based off of previous projects I don't see any problem..

What is expected?

command finishes

What is actually happening?

command never finishes and is stuck at "Success! Generated static files "

I never get returned to the CLI prompt

This wouldn't be that drastic, if CI systems don't need the command to finish in order to publish.

Other relevant information

• Your OS: Windows 10 (but the build also gets stuck on netlify)
• Node.js version: 8.9.x
• Is this a global or local install? both, tried via package.json and global
• Which package manager did you use for the install? npm

Oh, reproduced!

Thanks, fixed at: fa473a7

I'm trying to strip it down and reduce what is necessary.
It looks like the problem was with the setInterval in DataFuel.vue.

Thanks a lot for the quick fix!

@MartinMuzatko

In fact, I think we should avoid introducing process.exit in code, but this is the second time someone has encountered this problem, so I just solved it like this. I also think that this should be a problem with userland's code.

If you can find the root cause, please tell me, thank you!

When removing setInterval within created method, the build ends fine without process.exit. To me it looks like Vue SSR tries to wait for anything that it could prepare. But then the build process should get stuck somewhere else.

@ulivz I also fixed it by moving the setInterval functions to the mounted function :) so yes - my assumption should be correct

[ulivz]

Thanks, I just reverted the fix.

@ulivz is this something that Vue SSR should deal with? Or is this just common practice that timeouts/intervals should be avoided in created?

[ulivz]

created hook will be executed at both client and Node side, while mounted hook is client only.

And blocking exit when using setInterval isn't Vue but the Node's behavior.

For more information, you can try to understand the Event Loop of Node.js.
