react-use-search-params-state

React hook to use URL search params as state. It has the same API as useState and works with react-router-dom-v6.

Install

npm install react-use-search-params-state

or

yarn add react-use-search-params-state

Usage

Import the hook and the params definition type. Then create a params definition object containing the params you want to use.

The key is the name of the param. The value is an object with the following properties:

type: the type of the param. Can be string, number or boolean.

default: the default value of the param. If the param is not present in the URL, this value will be used.

multiple: (optional) if the param can have multiple values. If true, the value will be an array of the type specified in type.

Example:

import { useSearchParamsState, SearchParamsStateType } from 'react-use-search-params-state'

const filtersDefaults: SearchParamsStateType = {
  minPrice: { type: 'number', default: null },
  maxPrice: { type: 'number', default: null },
  isSold: { type: 'boolean', default: true },
  types: { type: 'string', default: null, multiple: true },
  years: { type: 'number', default: [], multiple: true },
}

Use the hook in your functional component the same way you use useState:

const TestFilters = () => {
  const [filterParams, setFilterParams] = useSearchParamsState(filtersDefaults)

  return <div>Min Price: {filterParams.minPrice}</div>
}

When you need to change any of the values, use the set... function with an object containing the name of the param and the new value(s):

<div>
  Min price:
  <input
    type='text'
    value={filterParams.minPrice ?? ''}
    onChange={(e) => setFilterParams({ minPrice: e.target.value })}
  />
  <button onClick={() => setFilterParams({ minPrice: 100 })}>set minPrice to 100</button>
</div>

The set... function will update only the params that are present in the object. The rest of the params will remain the same. This allow to have multiple components that can save their state in the URL without interfering with each other.

For a complete example, see the example/ folder or this CodeSandbox.
