reactjs 由于Next JS中其他兄弟组件的数据更新，导致一个兄弟组件重新呈现

我有一个Next JS应用程序，我在其中使用了_app.tsx组件中的布局功能。我在布局中显示了一个侧边栏，它是通过API调用（get request）填充的。
现在我在Index.tsx文件中有另一个API调用（更新请求），这个更新请求改变了布局的侧边栏组件中的数据。
以下是我的代码片段
_app.tsx

import { type AppType } from "next/app";
import { type Session } from "next-auth";
import { SessionProvider } from "next-auth/react";

import { trpc } from "../utils/trpc";

import "../styles/globals.css";
import MainLayout from "../components/layouts/MainLayout";

const MyApp: AppType<{ session: Session | null }> = ({
  Component,
  pageProps: { session, ...pageProps },
}) => {
  return (
    <SessionProvider session={session}>
      <MainLayout>
        <Component {...pageProps} />
      </MainLayout>
    </SessionProvider>
  );
};

export default trpc.withTRPC(MyApp);

MainLayout.tsx

import React, { useState } from "react";
import Link from "next/link";
import { useRouter } from "next/router";

import { trpc } from "../../utils/trpc";

import { AiOutlineOrderedList } from "react-icons/ai";
import { BsCartCheckFill, BsGraphUp, BsSuitHeartFill } from "react-icons/bs";
import { IoRefresh } from "react-icons/io5";
import { IoMdArrowBack } from "react-icons/io";
import { MdModeEditOutline } from "react-icons/md";

import { Space_Grotesk } from "@next/font/google";

import { SelectedData } from "@prisma/client";

const spaceGrotesk = Space_Grotesk({
  weight: "500",
  subsets: ["latin"],
});

type MainLayoutProps = {
  children: React.ReactNode;
};

type DefaultItemProps = {
  setItemMode: React.Dispatch<React.SetStateAction<"default" | "add" | "show">>;
  data: SelectedData[]
};

type ItemProps = {
  setItemMode: React.Dispatch<React.SetStateAction<"default" | "add" | "show">>;
};

const MainLayout = ({ children }: MainLayoutProps) => {
  const [itemMode, setItemMode] = useState<"default" | "add" | "show">(
    "default"
  );
  const pathname = useRouter().pathname.split("/")[1];

  const { data: selectedData } = trpc?.selectedData?.getAllData?.useQuery();

  return (

所以我的问题是，在从Index.tsx文件更新数据后，如何更新布局的侧边栏数据。

reactjs

一种解决方案是更新Home组件，使其包含一个状态，该状态表示datas属性和用户在使用购物清单时添加的任何数据。filteringList状态可以使用此“波动”状态，而不是使用传入的属性。额外的状态如下所示：

  • 注意 *：在任何使用datas属性的地方，都应该使用fluctuatingList。
const Home: NextPage<HomePageProps> = ({ datas }) => {
  const [fluctuatingList, setFluctuatingList] = useState(datas);
  // You can still set the filtered list to initially be set with `datas`
  const [filteringList, setFilteringList] = useState(datas);
  const [search, setSearch] = useState("");
  const mutation = trpc.selectedData.addItemToShopingList.useMutation();
...

然后在更新搜索时，使用fluxuatingListMap：

const searchHandler = (e: React.ChangeEvent<HTMLInputElement>) => {
    setSearch(e.target.value);
    // Check the line below
    const filteredList = fluctuatingList.map((list) => {
      return {
        ...list,
        items: list.items.filter((item) =>
          item.toLowerCase().includes(e.target.value.toLowerCase())
        ),
      };
    });
    setFilteringList(filteredList);
  };

现在，老实说，我没有花时间来消化您的代码片段以给予一个可用的解决方案，但猜测@prisma/client的Data类型是什么，我将假设它看起来像一个具有以下函数中三个参数的对象：

const addItemToShopingList = async (
    item: string,
    name: string,
    id: string
  ) => {
    if (mutation.error) {
      return alert("Something went wrong");
    }

    // Pulling this into a `const` for reuse
    const newData = {
      id,
      name,
      item,
    };

    // Here is where we mutate the data, I am guessing through some API call
    // We also want to set the fluctuating state here:
    setFluctuatingList((prevList) => ([ ...Array.from(prevList), newData ]));
    mutation.mutate(newData);
  };
