Options
Configuring nuqs
By default, nuqs
will update search params:
- On the client only (not sending requests to the server),
- by replacing the current history entry,
- and without scrolling to the top of the page.
These behaviours can be configured, along with a few additional options.
Providing options
Options can be passed at the hook level via the builder pattern:
Or when calling the state updater function, as a second parameter:
Call-level options will override hook level options.
History
By default, state updates are done by replacing the current history entry with the updated query when state changes.
You can see this as a sort of git squash
, where all state-changing
operations are merged into a single history value.
You can also opt-in to push a new history item for each state change, per key, which will let you use the Back button to navigate state updates:
Breaking the Back button can lead to a bad UX, make sure to use this option only if the search param(s) to update contribute to a navigation-like experience, where hacking the Back button is a UX enhancement rather than a nuisance.
— “With great power comes great responsibility.”
Shallow
By default, query state updates are done in a client-first manner: there are no network calls to the server.
This is equivalent to the shallow
option of the Next.js router set to true
.
To opt-in to query updates notifying the server (to re-run getServerSideProps
in the pages router and re-render Server Components on the app router),
you can set shallow
to false
:
Scroll
The Next.js router scrolls to the top of the page on navigation updates, which may not be desirable when updating the query string with local state.
Query state updates won’t scroll to the top of the page by default, but you can opt-in to this behaviour:
Throttling URL updates
Because of browsers rate-limiting the History API, updates to the URL are queued and throttled to a default of 50ms, which seems to satisfy most browsers even when sending high-frequency query updates, like binding to a text input or a slider.
Safari’s rate limits are much higher and require a throttle of 120ms (320ms for older versions of Safari).
If you want to opt-in to a larger throttle time — for example to reduce the amount
of requests sent to the server when paired with shallow: false
— you can
specify it under the throttleMs
option:
Note: the state returned by the hook is always updated instantly, to keep UI responsive. Only changes to the URL, and server requests when using
shallow: false
, are throttled.
If multiple hooks set different throttle values on the same event loop tick, the highest value will be used. Also, values lower than 50ms will be ignored, to avoid rate-limiting issues. Read more.
Specifying a +Infinity
value for throttleMs
will disable updates to the
URL or the server, which means useQueryState
will behave essentially like
React.useState
.
Transitions
When combined with shallow: false
, you can use React’s useTransition
hook
to get loading states while the server is re-rendering server components with
the updated URL.
Pass in the startTransition
function from useTransition
to the options
to enable this behaviour (this will set shallow: false
automatically for you):
Clear on default
By default, when the state is set to the default value, the search parameter is not removed from the URL, and is reflected explicitly. This is because default values can change, and the meaning of the URL along with it.
If you want to remove the search parameter from the URL when it’s set to the default
value, you can set clearOnDefault
to true
:
Clearing the key-value pair from the query string can always be done by setting the state to null
.
