How to read & update multiple search params at once

Multiple updates (batching)

You can call as many state update function as needed in a single event loop tick, and they will be applied to the URL asynchronously:

const MultipleQueriesDemo = () => {
  const [lat, setLat] = useQueryState('lat', parseAsFloat)
  const [lng, setLng] = useQueryState('lng', parseAsFloat)
  const randomCoordinates = React.useCallback(() => {
    setLat(Math.random() * 180 - 90)
    setLng(Math.random() * 360 - 180)
  }, [])
}

If you wish to know when the URL has been updated, and what it contains, you can await the Promise returned by the state updater function, which gives you the updated URLSearchParameters object:

const randomCoordinates = React.useCallback(() => {
  setLat(42)
  return setLng(12)
}, [])
 
randomCoordinates().then((search: URLSearchParams) => {
  search.get('lat') // 42
  search.get('lng') // 12, has been queued and batch-updated
})

Implementation details (Promise caching)

The returned Promise is cached until the next flush to the URL occurs, so all calls to a setState (of any hook) in the same event loop tick will return the same Promise reference.

Due to throttling of calls to the Web History API, the Promise may be cached for several ticks. Batched updates will be merged and flushed once to the URL. This means not every setState will reflect to the URL, if another one comes overriding it before flush occurs.

The returned React state will reflect all set values instantly, to keep UI responsive.

`useQueryStates`

For query keys that should always move together, you can use useQueryStates with an object containing each key’s type:

import { useQueryStates, parseAsFloat } from 'nuqs'
 
const [coordinates, setCoordinates] = useQueryStates(
  {
    lat: parseAsFloat.withDefault(45.18),
    lng: parseAsFloat.withDefault(5.72)
  },
  {
    history: 'push'
  }
)
 
const { lat, lng } = coordinates
 
// Set all (or a subset of) the keys in one go:
const search = await setCoordinates({
  lat: Math.random() * 180 - 90,
  lng: Math.random() * 360 - 180
})

Options

There are three places you can define options in useQueryStates:

As the second argument to the hook itself (global options, see above)
On each parser, like parseAsFloat.withOptions({ shallow: false })
At the call level when updating the state:

setCoordinates({
  lat: 42,
  lng: 12
}, {
  shallow: false
})

The order of precedence is: call-level options > parser options > global options.

Tip

You can clear all keys managed by a useQueryStates hook by passing null to the state updater function.

const clearAll = () => setCoordinates(null)

This will clear lat & lng, and leave other search params untouched.
