perf: ⚡ generate static params from registry.json

[lloydrichards]

Goals/Scope

After getting the routing working and taking a look at the build I realised there are some optimisations that could be done with generating the params using the registry.json. This should turn the routes into SSG instead of Dynamic which will save some CPU time on edge functions and reduce potential costs.

Description

Just added the generateStaticParams to fetch the registry.json and map out all the item names. The result:

Route (app)                              Size     First Load JS
┌ ○ /                                    9.28 kB         114 kB
├ ○ /_not-found                          982 B           106 kB
└ ● /registry/[name]                     135 B           105 kB
    ├ /registry/complex-component
    ├ /registry/example-form
    └ /registry/hello-world
+ First Load JS shared by all            105 kB
  ├ chunks/4bd1b696-1e3aa08efae9c30b.js  53 kB
  ├ chunks/517-44104b656c9b8dc3.js       50.3 kB
  └ other shared chunks (total)          1.84 kB


○  (Static)  prerendered as static content
●  (SSG)     prerendered as static HTML (uses generateStaticParams)
