[Feature request] Improve shouldPrefetch default value #953

Open Mister-Hope opened 2 years ago

Mister-Hope commented 2 years ago

Clear and concise description of the problem

Currenly the shouldPrefetch: true default behavior have serious preformance impact on large sites with FCP time.

For a large site with around 1500 pages, shouldPrefetch link can take up to 30-50KB in each html entry.

Suggested solution

As @meteorlxy suggests earlier, we can change the default behavior to only prefetch assets which can be visited through the page.

Or more detailed:

  1. find all links in the page, (also home and 404)
  2. find all links in navbar and sidebar
  3. Combine them together with a link array
  4. Get all the preload links of them
  5. filter the duplicated ones
  6. Set them as default value of shouldPretch

But this requires improvments mentioned in https://github.com/vuepress/vuepress-next/issues/952
