As you navigate around take note of the UX. It should feel
suspense-like, where routes are only rendered once all of their data and
elements are ready.
<hr className={`my-2`} />
To exaggerate async effects, play with the artificial request delay
slider in the bottom-left corner.
<hr className={`my-2`} />
The last 2 sliders determine if link-hover preloading is enabled (and
how long those preloads stick around) and also whether to cache rendered
route data (and for how long). Both of these default to 0 (or off).

Normally, setting default search parameters would either need to be done
manually in every link to a page, or as a side-effect (not a great
experience).
</p>
<p>
Instead, we can use <strong>search filters</strong> to provide defaults
or even persist search params for links to routes (and child routes).
</p>
<p>
A good example of this is the sorting and filtering of the users list.
In a traditional router, both would be lost while navigating around
individual users or even changing each sort/filter option unless each
state was manually passed from the current route into each new link we
created (that's a lot of tedious and error-prone work). With TanStack
router and search filters, they are persisted with little effort.

As you navigate around take note of the UX. It should feel
suspense-like, where routes are only rendered once all of their data and
elements are ready.

To exaggerate async effects, play with the artificial request delay
slider in the bottom-left corner.
<hr className={`my-2`} />
The last 2 sliders determine if link-hover preloading is enabled (and
how long those preloads stick around) and also whether to cache rendered
route data (and for how long). Both of these default to 0 (or off).

Normally, setting default search parameters would either need to be done
manually in every link to a page, or as a side-effect (not a great
experience).
</p>
<p>
Instead, we can use <strong>search filters</strong> to provide defaults
or even persist search params for links to routes (and child routes).
</p>
<p>
A good example of this is the sorting and filtering of the users list.
In a traditional router, both would be lost while navigating around
individual users or even changing each sort/filter option unless each
state was manually passed from the current route into each new link we
created (that's a lot of tedious and error-prone work). With TanStack
router and search filters, they are persisted with little effort.
