25 millions

[FranckFreiburger]

While casually exploring the various usage statistics of vue3-sfc-loader, I was pleasantly surprised to discover that vue3-sfc-loader is being downloaded (directly or indirectly) nearly 2 millions times per month on the jsdelivr CDN and almost 25 millions times over the course of the year 2023. Additionally, jsdelivr activates a Cache-Control max-age=31536000. This implies that vue3-sfc-loader is executed even more frequently!

This revelation fills me with joy, enthusiasm, and questions.

Repetitive client-side compilation of the same source file is a significant waste of CPU cycles (i.e., energy and time) because it is a task performed numerous times without tangible benefit.

While vue3-sfc-loader already incorporates a mechanism for caching compiled sources, I believe it is vastly underutilized.

Hence, I propose the implementation of a basic client-side caching system for vue3-sfc-loader compiled assets.

Implementing this will, initially, prevent the repeated compilation of the same file for a same user. I'm thinking about an identical mechanism on the server side (see #178).

    class CompileCache {
    ...
    }

See implementation here: #175

Usage:
just add compiledCache: new CompileCache() in your vue3-sfc-loader options like this:

    const options = {
      ...
      compiledCache: new CompileCache(),
      ...
    }
