Params and Search in template.tsx

Goals

Add support for params and search params to template.tsx

Non-Goals

Not intended to change behavior of current template.tsx: it currently supports being both a server component and client component

Background

I am using a new intl library (https://intlayer.org/) and the developer requires to put a server provider in each page, since it may change on a page-basis. Having this supported in a better way by the framework would be awesome (and probably lead to many new use cases)

As per documentation:

Official Next template.js file documentation

Unlike Pages, Layouts (Server Components) do not receive the searchParams prop. This is because a shared layout is not re-rendered during navigation

that means that theoretically template.tsx could support params and search params, since it's re-rendered on a page basis.

Pages
To access search params in Pages (Server Components), use the searchParams prop.

Layouts
Unlike Pages, Layouts (Server Components) do not receive the searchParams prop. This is because a shared layout is not re-rendered during navigation which could lead to stale searchParams between navigations. View detailed explanation.

Proposal

Add support for params and search params to template.tsx, as done for pages
