Use GET requests with preloading for Server Islands
|
||
|
|
|
||
|
|
Server Island requests include the props used to render the island as well as any slots passed in (excluding the fallback slot). Since browsers have a max 4mb URL length we default to using a POST request to avoid overflowing this length.
|
||
|
|
|
||
|
|
However in reality most usage of Server Islands are fairly isolated and won't exceed this limit, so a GET request is possible by passing this same information via search parameters.
|
||
|
|
|
||
|
|
Using GET means we can also include a `<link rel="preload">` tag to speed up the request.
|
||
|
|
|
||
|
|
This change implements this, with safe fallback to POST.
