serverPrefetch not called in dev

• I confirm that this is an issue rather than a question.

Bug report

Version

1.0.0-alpha.44

Steps to reproduce

I have a serverPrefetch method in a component.
When building dist, the method is properly called and the component work.

When using dev server, the method seems to be not called.

async serverPrefetch() {
    this.foo = await fetchData();
  },

Thanks.

Actually, I'm seeing that even if the method is called during the build, the foo data is emptied when the app loads. I probably missed something and will investigate further.

serverPrefetch was added in Vue@2.6+ but VuePress is powered by Vue@2.5+.

@ulivz You should not have read my previous messages, as you would know that it works.

Moreover, sorry to tell you that but actually vuepress is running vue@2.6.9, which is quite normal as it is requested as "vue": "^2.5.16", in https://github.com/vuejs/vuepress/blob/master/packages/%40vuepress/core/package.json#L57

Also sorry to tell you:

Yeah, I know that, this is server prefetching 🤷‍♂️ .
Are you saying that the dev server isn't doing any ssr at all?

I'm sorry but I totally don't understand what's going on here: firstly the wrong version response, and now this screenshot. Am I missing something? I'm sorry if I did or wrote something that bothered you. 🤔

Here what I'm trying to do is to make some calls only on server side, and not client side. It seems to work with build phase, but not dev one.
