useSearchParams (RN)

useSearchParams (React Native)

This is the React Native version of useSearchParams. For the web version, go here.

Type declaration
declare function useSearchParams(
  defaultInit?: URLSearchParamsInit
): [URLSearchParams, SetURLSearchParams];

type ParamKeyValuePair = [string, string];

type URLSearchParamsInit =
  | string
  | ParamKeyValuePair[]
  | Record<string, string | string[]>
  | URLSearchParams;

type SetURLSearchParams = (
  nextInit?:
    | URLSearchParamsInit
    | ((prev: URLSearchParams) => URLSearchParamsInit),
  navigateOpts?: : NavigateOptions
) => void;

interface NavigateOptions {
  replace?: boolean;
  state?: any;
  preventScrollReset?: boolean;
}

The useSearchParams hook is used to read and modify the query string in the URL for the current location. Like React's own useState hook, useSearchParams returns an array of two values: the current location's search params and a function that may be used to update them. Just as React's useState hook, setSearchParams also supports functional updates. Therefore, you may provide a function that takes a searchParams and returns an updated version.

import * as React from "react";
import { View, SearchForm, TextInput } from "react-native";
import { useSearchParams } from "react-router-native";

function App() {
  let [searchParams, setSearchParams] = useSearchParams();
  let [query, setQuery] = React.useState(
    searchParams.get("query")
  );

  function handleSubmit() {
    setSearchParams({ query });
  }

  return (
    <View>
      <SearchForm onSubmit={handleSubmit}>
        <TextInput value={query} onChangeText={setQuery} />
      </SearchForm>
    </View>
  );
}
