React 自定义hook 通过 url search 来管理

2022-01-11  本文已影响0人  学生黄哲
1、使用 react-router

useUrlSearchState 使用 react-router 6.x 版本来管理路由 如需使用5.x使用 useHistory 替换 useNavigate

/* eslint-disable react-hooks/exhaustive-deps */
import { parse, stringify } from 'query-string';
import type { ParseOptions, StringifyOptions } from 'query-string';
import { useMemo, useRef, useCallback, SetStateAction, useState, useEffect } from 'react';
import { useLocation, useNavigate } from 'react-router';

function getDefaultSearch(searchKeys?: string[]) {
  if (!searchKeys) return;

  const obj: any = {};
  searchKeys.forEach((i) => {
    obj[i] = undefined;
  });
  return obj;
}
function getSearchObj(searchKeys?: string[], searchObj?: any) {
  if (!searchKeys) return searchObj;

  const obj: any = {};
  searchKeys.forEach((i) => {
    if (searchObj[i]) obj[i] = searchObj[i];
  });
  return obj;
}

export interface Options {
  navigateMode?: 'push' | 'replace';
  parseOptions?: ParseOptions;
  stringifyOptions?: StringifyOptions;
  searchKeys?: string[];
}

const baseParseConfig: ParseOptions = {
  parseNumbers: false,
  parseBooleans: false,
  arrayFormat: 'index',
};

const baseStringifyConfig: StringifyOptions = {
  skipNull: false,
  skipEmptyString: false,
  arrayFormat: 'index',
};

type UrlState = Record<string, any>;

export default function useUrlSearchState<S extends UrlState = UrlState>(
  initialState?: S | (() => S),
  options?: Options,
) {
  type State = Partial<{ [key in keyof S]: any }>;
  const { navigateMode = 'push', parseOptions, stringifyOptions, searchKeys } = options || {};

  const mergedParseOptions = { ...baseParseConfig, ...parseOptions };
  const mergedStringifyOptions = { ...baseStringifyConfig, ...stringifyOptions };

  const navigate = useNavigate();
  const [, update] = useState({});
  const { search, hash } = useLocation();
  const hashRef = useRef<string>();
  useEffect(() => {
    hashRef.current = hash;
  });
  const initialStateRef = useRef(typeof initialState === 'function' ? (initialState as () => S)() : initialState || {});

  const queryFromUrl = useMemo(() => {
    return parse(search, mergedParseOptions);
  }, [search]);
  const defaultSearch = useMemo(() => getDefaultSearch(searchKeys), [searchKeys]);

  const targetQuery: State = useMemo(
    () =>
      getSearchObj(searchKeys, {
        ...initialStateRef.current,
        ...queryFromUrl,
      }),
    [queryFromUrl],
  );

  const setSearch = useCallback(
    (search: string) => {
      navigate({ hash: hashRef.current, search }, { replace: navigateMode === 'replace' });
    },
    [navigate],
  );

  const setState = useCallback(
    (s: SetStateAction<State>) => {
      const newQuery = typeof s === 'function' ? s(targetQuery) : s;
      setSearch(stringify({ ...queryFromUrl, ...(defaultSearch ?? {}), ...newQuery }, mergedStringifyOptions) || '?');
      update({});
    },
    [setSearch, queryFromUrl, targetQuery, defaultSearch],
  );

  const clear = useCallback(() => {
    !defaultSearch ? setSearch('') : setState(defaultSearch);
  }, [defaultSearch, setState]);

  return [targetQuery, setState, clear] as const;
}


2、如果没有使用react-router来管理路由

注:使用此版本useUrlSearchState不要和hash一块使用,如果需要使用hash来管理state可以使用 react-use useHash

useUrlSearchState.ts

/* eslint-disable react-hooks/exhaustive-deps */
import { parse, stringify } from 'query-string';
import type { ParseOptions, StringifyOptions } from 'query-string';
import { useMemo, useRef, useCallback, SetStateAction, useState } from 'react';
import useLocation from './useLocation';

function getDefaultSearch(searchKeys?: string[]) {
  if (!searchKeys) return;

  const obj: any = {};
  searchKeys.forEach((i) => {
    obj[i] = undefined;
  });
  return obj;
}
function getSearchObj(searchKeys?: string[], searchObj?: any) {
  if (!searchKeys) return searchObj;

  const obj: any = {};
  searchKeys.forEach((i) => {
    if (searchObj[i]) obj[i] = searchObj[i];
  });
  return obj;
}

export interface Options {
  navigateMode?: 'push' | 'replace'; //切换 history 的方式
  parseOptions?: ParseOptions; //query-string ParseOptions
  stringifyOptions?: StringifyOptions; //query-string StringifyOptions
  searchKeys?: string[]; //需要管理的keys
}

const baseParseConfig: ParseOptions = {
  parseNumbers: false,
  parseBooleans: false,
  arrayFormat: 'index',
};

const baseStringifyConfig: StringifyOptions = {
  skipNull: false,
  skipEmptyString: false,
  arrayFormat: 'index',
};

type UrlState = Record<string, any>;

export default function useUrlSearchState<S extends UrlState = UrlState>(
  initialState?: S | (() => S),
  options?: Options,
) {
  type State = Partial<{ [key in keyof S]: any }>;
  const { navigateMode = 'push', parseOptions, stringifyOptions, searchKeys } = options || {};

  const mergedParseOptions = { ...baseParseConfig, ...parseOptions };
  const mergedStringifyOptions = { ...baseStringifyConfig, ...stringifyOptions };

  const [, update] = useState({});
  const { search } = useLocation();

  const initialStateRef = useRef(typeof initialState === 'function' ? (initialState as () => S)() : initialState || {});

  const queryFromUrl = useMemo(() => {
    return parse(search || '', mergedParseOptions);
  }, [search]);
  const defaultSearch = useMemo(() => getDefaultSearch(searchKeys), [searchKeys]);
  const targetQuery: State = useMemo(
    () =>
      getSearchObj(searchKeys, {
        ...initialStateRef.current,
        ...queryFromUrl,
      }),
    [queryFromUrl, searchKeys],
  );
  const setSearch = useCallback((search: string) => {
    history[navigateMode === 'replace' ? 'replaceState' : 'pushState'](
      null,
      '',
      search ? '?' + search : location.origin,
    );
  }, []);

  const setState = useCallback(
    (s: SetStateAction<State>) => {
      const newQuery = typeof s === 'function' ? s(targetQuery) : s;
      setSearch(stringify({ ...queryFromUrl, ...(defaultSearch ?? {}), ...newQuery }, mergedStringifyOptions) || '?');
      update({});
    },
    [setSearch, queryFromUrl, targetQuery, defaultSearch],
  );

  const clear = useCallback(() => {
    !defaultSearch ? setSearch('') : setState(defaultSearch);
  }, [defaultSearch, setSearch, setState]);

  return [targetQuery, setState, clear] as const;
}

useLocation.ts fork 自 react-use useLocation

import { useEffect, useState } from 'react';

export function on<T extends Window | Document | HTMLElement | EventTarget>(
  obj: T | null,
  ...args: Parameters<T['addEventListener']> | [string, Function | null, ...any]
): void {
  if (obj && obj.addEventListener) {
    obj.addEventListener(...(args as Parameters<HTMLElement['addEventListener']>));
  }
}

export function off<T extends Window | Document | HTMLElement | EventTarget>(
  obj: T | null,
  ...args: Parameters<T['removeEventListener']> | [string, Function | null, ...any]
): void {
  if (obj && obj.removeEventListener) {
    obj.removeEventListener(...(args as Parameters<HTMLElement['removeEventListener']>));
  }
}

export const isBrowser = typeof window !== 'undefined';

const patchHistoryMethod = (method: 'pushState' | 'replaceState') => {
  const history = window.history;
  const original = history[method];

  history[method] = function (state) {
    // eslint-disable-next-line prefer-rest-params
    const result = original.apply(this, arguments as any);
    const event = new Event(method.toLowerCase());

    (event as any).state = state;

    window.dispatchEvent(event);

    return result;
  };
};

if (isBrowser) {
  patchHistoryMethod('pushState');
  patchHistoryMethod('replaceState');
}

export interface LocationSensorState {
  trigger: string;
  state?: any;
  length?: number;
  hash?: string;
  host?: string;
  hostname?: string;
  href?: string;
  origin?: string;
  pathname?: string;
  port?: string;
  protocol?: string;
  search?: string;
}

const useLocationServer = (): LocationSensorState => ({
  trigger: 'load',
  length: 1,
});

const buildState = (trigger: string) => {
  const { state, length } = window.history;

  const { hash, host, hostname, href, origin, pathname, port, protocol, search } = window.location;

  return {
    trigger,
    state,
    length,
    hash,
    host,
    hostname,
    href,
    origin,
    pathname,
    port,
    protocol,
    search,
  };
};

const useLocationBrowser = (): LocationSensorState => {
  const [state, setState] = useState(buildState('load'));

  useEffect(() => {
    const onPopstate = () => setState(buildState('popstate'));
    const onPushstate = () => setState(buildState('pushstate'));
    const onReplacestate = () => setState(buildState('replacestate'));

    on(window, 'popstate', onPopstate);
    on(window, 'pushstate', onPushstate);
    on(window, 'replacestate', onReplacestate);

    return () => {
      off(window, 'popstate', onPopstate);
      off(window, 'pushstate', onPushstate);
      off(window, 'replacestate', onReplacestate);
    };
  }, []);

  return state;
};

const hasEventConstructor = typeof Event === 'function';

export default isBrowser && hasEventConstructor ? useLocationBrowser : useLocationServer;
