@kimaramyz/use-query-params

@kimaramyz/use-query-params is a library of React hooks for using URL query params as state. Light-weight, TS support and no dependencies. This allows you to easily encode and decode data of primitive type. Implemented by History API and URLSearchParams API.

Background

When creating apps with easily shareable URLs, you often want to encode state as query parameters, but all query parameters must be encoded as strings.

If you are doing a React-based project, you will probably be using ReactRouter or NextRouter together. However, the part where these routers use query string as a state, i.e., useSearchParams, returns instance of URLSearchParams, so you may need to parse it again. Therefore, this library can help you when you're trying to use query params with ReactRouter or NextRouter, and the other History API-based router libraries.

Features

• Provides three options of URL query hooks

  • useQueryParams
  • useQueryParam
  • useQueryString

• Provides useful options

  • Shallow routing - Able to update query parameter with no history changes
  • Hard/Soft key-value deletion (Upcoming)

• No adapter required

• Typescript support

• Light-weight (5KB)

• No dependencies.

  • No serializer library dependent
  • No router library dependent
  • Perfectly compatible with any version of ReactRouter

API

useQueryParams

Type declaration

declare function useQueryParams<KeyEnum extends string>(options?: {
  isShallow?: boolean;
}): [
  { [key in KeyEnum]?: string | undefined },
  (queryParams: { [key in KeyEnum]?: unknown }) => void
];

Basic example

import { FC } from 'react';
import { useQueryParams } from '@kimaramyz/use-query-params';

const BasicExample: FC = () => {
  const [queryParams, setQueryParams] = useQueryParams<'page' | 'q'>();

  return (
    <div>
      <h1>queryParams: {JSON.stringify(queryParams, null, 2)}</h1>
      <button onClick={() => setQueryParams({ ...queryParams, page: 2 })}>
        Upsert pageParam
      </button>
      <button
        onClick={() => setQueryParams({ ...queryParams, page: undefined })}
      >
        Delete pageParam
      </button>
      <button onClick={() => setQueryParams(null)}>Clear</button>
    </div>
  );
};

Using shallow routing

import { FC } from 'react';
import { useQueryParams } from '@kimaramyz/use-query-params';

const ShallowRoutingExample: FC = () => {
  const [queryParams, setQueryParams] = useQueryParams<'page' | 'q'>({
    isShallow: true,
  });

  return (
    <div>
      <h1>queryParams: {JSON.stringify(queryParams, null, 2)}</h1>
      <h2>history.length: {window.history.length}</h2>
      <button onClick={() => setQueryParams({ ...queryParams, page: 2 })}>
        Upsert pageParam
      </button>
      <button
        onClick={() => setQueryParams({ ...queryParams, page: undefined })}
      >
        Delete pageParam
      </button>
      <button onClick={() => setQueryParams(null)}>Clear</button>
    </div>
  );
};

useQueryParam

Type declaration

declare function useQueryParam<T = string>(
  key: string,
  options?: {
    isShallow?: boolean;
  }
): [T | null | undefined, (value: unknown) => void];

Basic example

import { FC } from 'react';
import { useQueryParam } from '@kimaramyz/use-query-params';

const BasicExample: FC = () => {
  const [page, setPage] = useQueryParam('page');

  return (
    <div>
      <h1>page: {page}</h1>
      <button onClick={() => setPage(1)}>Upsert</button>
      <button onClick={() => setPage(undefined)}>Clear</button>
    </div>
};

Using shallow routing

import { FC } from 'react';
import { useQueryParam } from '@kimaramyz/use-query-params';

const ShallowRoutingExample: FC = () => {
  const [page, setPage] = useQueryParam('page', { isShallow: true });

  return (
    <div>
      <h1>page: {page}</h1>
      <h2>history.length: {window.history.length}</h2>
      <button onClick={() => setPage(1)}>Upsert</button>
      <button onClick={() => setPage(undefined)}>Clear</button>
    </div>
  );
};

useQueryString

Type declaration

declare function useQueryString(options?: {
  isShallow?: boolean;
}): [
  string,
  (queryString: string | null | undefined, historyState?: unknown) => void
];

Basic example

import { FC } from 'react';
import { useQueryString } from '@kimaramyz/use-query-params';

const BasicExample: FC = () => {
  const [queryString, setQueryString] = useQueryString();

  return (
    <div>
      <h1>queryString: {queryString}</h1>
      <button onClick={() => setQueryString('?page=1&q=foo')}>Upsert</button>
      <button onClick={() => setQueryString(undefined)}>Clear</button>
    </div>
  );
};

Using shallow routing

import { FC } from 'react';
import { useQueryString } from '@kimaramyz/use-query-params';

const ShallowRoutingExample: FC = () => {
  const [queryString, setQueryString] = useQueryString({ isShallow: true });

  return (
    <div>
      <h1>queryString: {queryString}</h1>
      <h2>history.length: {window.history.length}</h2>
      <button onClick={() => setQueryString('?page=1&q=foo')}>Upsert</button>
      <button onClick={() => setQueryString(undefined)}>Clear</button>
    </div>
  );
};
