目標:

私たちの目標は、React CRUD アプリケーションを開発することです。

私たちのスタック:

• 反応形式
ゾッド
ag-grid-react
反応クエリ
json-server

セットアップ環(huán)境：

vite を使用して反応プロジェクトを作成します:

npm create vite@latest crud-react -- --template react-ts

依存関係をインストールします:

npm install react-hook-form zod @hookform/resolvers ag-grid-react react-query axios

サーバーを作成して起動します。

オブジェクト (プロダクト) 構(gòu)造:

{
    "id": "w38y",
    "name": "Vitamin C Tablets",
    "price": 19.99,
    "expiryDate": "2025-01-01",
    "emailSupplier": "contact@healthplus.com"
}

/db/db.json にサンプル データを含むファイルを作成します:

{
? "products": [
? ? {
? ? ? "id": "w38y",
? ? ? "name": "Vitamin C Tablets",
? ? ? "price": 19.99,
? ? ? "expiryDate": "2025-01-01",
? ? ? "emailSupplier": "contact@healthplus.com"
? ? },
? ? {
? ? ? "id": "a99x",
? ? ? "name": "Omega-3 Fish Oil",
? ? ? "price": 30.99,
? ? ? "expiryDate": "2024-11-15",
? ? ? "emailSupplier": "support@nutricore.com"
? ? },
? ? {
? ? ? "id": "x82j",
? ? ? "name": "Calcium + Vitamin D",
? ? ? "price": 15.5,
? ? ? "expiryDate": "2026-06-01",
? ? ? "emailSupplier": "orders@welllifelabs.com"
? ? },
? ? {
? ? ? "id": "a40i",
? ? ? "name": "Zinc Lozenges",
? ? ? "price": 12.99,
? ? ? "expiryDate": "2024-09-30",
? ? ? "emailSupplier": "sales@herbalessentials.com"
? ? },
? ? {
? ? ? "id": "c52f",
? ? ? "name": "Probiotic Capsules",
? ? ? "price": 25.75,
? ? ? "expiryDate": "2025-03-20",
? ? ? "emailSupplier": "info@guthealthlabs.com"
? ? }
? ]
}

json-server を開始します:

npx json-server db/db.json

反応クエリを設(shè)定します。

/src/App.tsx を更新します:

import { QueryClient, QueryClientProvider } from "react-query";

const queryClient = new QueryClient();

function App() {
? return (
? ? <QueryClientProvider client={queryClient}>
? ? </QueryClientProvider>
? );
}

export default App;

/src/types.ts を作成します:

export type FormData = {
? name: string;
? price: number;
? expiryDate: string;
? emailSupplier: string;
};

export type FormFieldNames = "name" | "price" | "expiryDate" | "emailSupplier";  

export type Product = {
? id: string;
? name: string;
? price: number;
? expiryDate: string;
? emailSupplier: string;
};

/src/server/productQuery.ts を作成します:

import { useMutation, useQuery, useQueryClient } from "react-query";
import { FormData, Product } from "../types";
import axios from "axios";

const URL = "http://localhost:3000";
const PRODUCTS = "products";

export const save = async (product: FormData) =>
? axios.post(`${URL}/${PRODUCTS}`, product);

export const useSave = () => {
? const queryClient = useQueryClient();

? return useMutation({
? ? mutationFn: (newProduct: FormData) => save(newProduct),
? ? onSuccess: () => {
? ? ? queryClient.invalidateQueries({ queryKey: [PRODUCTS] });
? ? },
? });
};

export const fetch = async () => {
? const result = await axios.get(`${URL}/${PRODUCTS}`);
? return result.data;
};

export const useProducts = () =>
? useQuery<Product[]>({
? ? queryKey: [PRODUCTS],
? ? queryFn: fetch,
? });

const remove = async (id: string) => {
? await axios.delete(`${URL}/${PRODUCTS}/${id}`);
};

export const useRemove = () => {
? const queryClient = useQueryClient();

? return useMutation({
? ? mutationFn: (id: string) => remove(id),
? ? onSuccess: () => {
? ? ? queryClient.invalidateQueries({ queryKey: [PRODUCTS] });
? ? },
? });
};

export const update = async (product: Product) =>
? axios.put(`${URL}/${PRODUCTS}/${product.id}`, product);

export const useUpdate = () => {
? const queryClient = useQueryClient();

? return useMutation({
? ? mutationFn: (product: Product) => update(product),
? ? onSuccess: () => {
? ? ? queryClient.invalidateQueries({ queryKey: [PRODUCTS] });
? ? },
? });
};

フォームの作成:

/src/types.ts を更新します:

import { z, ZodType } from "zod";

export type FormData = {
? name: string;
? price: number;
? expiryDate: string;
? emailSupplier: string;
};

export type FormFieldNames = "name" | "price" | "expiryDate" | "emailSupplier";

export const ProductSchema: ZodType<FormData> = z.object({
? name: z.string().min(3),
? price: z.number().min(1).max(1000),
? expiryDate: z
? ? .string()
? ? .refine(
? ? ? (date) => new Date(date) > new Date(),
? ? ? "Expiry Date must be superior than current date",
? ? ),
? emailSupplier: z.string().email(),
});



export type Product = {
? id: string;
? name: string;
? price: number;
? expiryDate: string;
? emailSupplier: string;
};

/src/components/form/FormField.tsx を作成します:

import { FormData, FormFieldNames } from "../../types";

type FormFieldProps = {
? type: string;
? placeholder: string;
? name: FormFieldNames;
? register: UseFormRegister<FormData>;
? error: FieldError | undefined;
? valueAsNumber?: boolean;
? step?: number | string;
};

const FormField = ({
? type,
? placeholder,
? name,
? register,
? error,
? valueAsNumber,
? step,
}: FormFieldProps) => (
? <>
? ? <input
? ? ? type={type}
? ? ? placeholder={placeholder}
? ? ? step={step}
? ? ? {...register(name, { valueAsNumber })}
? ? />
? ? {error && <span> {error.message} </span>}
? </>
);

export default FormField;

import FormField from "./FormField";
import { FormData, ProductSchema } from "../../types";
import { zodResolver } from "@hookform/resolvers/zod";
import { useSave } from "../../server/productQuery";

const Form = () => {
? const {
? ? register,
? ? handleSubmit,
? ? formState: { errors },
? } = useForm<FormData>({
? ? resolver: zodResolver(ProductSchema),
? });

? const mutation = useSave();

? const onSubmit = (data: FormData) => {
? ? mutation.mutate(data);
? };

? return (
? ? <form onSubmit={handleSubmit(onSubmit)}>
? ? ? <div>
? ? ? ? <FormField
? ? ? ? ? type="text"
? ? ? ? ? placeholder="Name"
? ? ? ? ? name="name"
? ? ? ? ? register={register}
? ? ? ? ? error={errors.name}
? ? ? ? />
? ? ? ? <FormField
? ? ? ? ? type="number"
? ? ? ? ? placeholder="Price"
? ? ? ? ? name="price"
? ? ? ? ? step="0.01"
? ? ? ? ? register={register}
? ? ? ? ? error={errors.price}
? ? ? ? ? valueAsNumber
? ? ? ? />
? ? ? ? <FormField
? ? ? ? ? type="date"
? ? ? ? ? placeholder="Expiry Date"
? ? ? ? ? name="expiryDate"
? ? ? ? ? register={register}
? ? ? ? ? error={errors.expiryDate}
? ? ? ? />

? ? ? ? <FormField

? ? ? ? ? register={register}
? ? ? ? ? error={errors.emailSupplier}
? ? ? ? />
? ? ? ? <button type="submit">Add</button>
? ? ? </div>
? ? </form>
? );
};

export default Form;

import { AgGridReact } from "ag-grid-react";
import { ColDef, ColGroupDef } from "ag-grid-community";
import "ag-grid-community/styles/ag-grid.css";
import "ag-grid-community/styles/ag-theme-quartz.css";

const Products = () => {

? const removeMutation = useRemove();
? const updateMutation = useUpdate();

? const columns = useMemo<(ColDef | ColGroupDef<Product>)[]>(

? ? ? { field: "name", editable: true },
? ? ? { field: "price", editable: true },
