[Docs]: RR7 lazyRouteDiscover (Fog of War) opt-out

[mikkpokk]

Missing information how to disable lazy route discover (also known as Fog of War) feature.

In my case, it causes unnecessary overhead on application which renders thousands of links (filters and products) but there are only 7 RR routes in total. Would love to disable the feature.

Same here. Would love to see a way to opt out the feature or configure it.

We need more control over Fog of War. I noticed the same issue, we have a search results page where each result is a different link. React Router fetches a manifest for all the links, but it's just a single route with parameters. It would be great to have some way to exclude links from discovery and just use whatever is already loaded.

The initial manifest only contains the matched routes. Therefore a manifest is always fetched on page load. We should have an (optional) option to eagerly load those as well.

I digged a bit deeper in source code and it seems there is only 1 solution - use discover={'none'} property value on NavLink / Link component on most of the links and let FOW to do it's thing on single route link only.

For an example

// Main navigation
<Link to={'/'}>Home</Link>
<Link to={'/products'}>Products</Link>
<Link to={'/login'}>Login</Link>
<Link to={'/register'}>Register</Link>
...
// Filters
<Link to={'/products?color[]=blue'} discover={'none'}>Blue</Link>
<Link to={'/products?color[]=red'} discover={'none'}>Red</Link>
<Link to={'/products?color[]=red&color[]=blue'} discover={'none'}>Blue</Link> // in case red is active already
<Link to={'/products?color[]=blue&color[]=red'} discover={'none'}>Red</Link> // in case blue is active already

// Pagination
<Link to={'/products?page=2'} discover={'none'}>2</Link>

// Products
{items.map((item, key) => (
    <Link to={`/products/${item.slug}`} discover={'none'}>
        <ProductCard item={item} discover={key === 0 ? 'render' : 'none'} />
    </Link>
))}

However, it gets really messy and hard to maintain such a mayhem project in the future. Let's hope to hear authors thoughts soon.
