useRouteQuery

Usage

import { useRouteQuery } from '@vueuse/router'

const search = useRouteQuery('search')

const search = useRouteQuery('search', 'foo') // or with a default value

const page = useRouteQuery('page', '1', { transform: Number }) // or transforming value

console.log(search.value) // route.query.search
search.value = 'foobar' // router.replace({ query: { search: 'foobar' } })

By default, changes use router.replace(). Set mode: 'push' to use router.push() instead.

import { useRouteQuery } from '@vueuse/router'

const search = useRouteQuery('search', '', { mode: 'push' })

Bidirectional Transform

You can provide separate get and set transforms for reading and writing values.

import { useRouteQuery } from '@vueuse/router'

const filters = useRouteQuery('filters', [], {
  transform: {
    get: v => v ? v.split(',') : [],
    set: v => v.join(','),
  },
})

// Reading: 'a,b,c' -> ['a', 'b', 'c']
// Writing: ['a', 'b', 'c'] -> 'a,b,c'

Default Value Behavior

When the value equals the default value, the query parameter is removed from the URL.

import { useRouteQuery } from '@vueuse/router'

const page = useRouteQuery('page', '1')

page.value = '2' // URL: ?page=2
page.value = '1' // URL: (no page param, since it equals default)

Type Declarations
