在本博客中，我们将使用 React 构建一个食谱查找网站。该应用程序允许用户搜索他们最喜欢的食谱，查看趋势或新食谱，并保存他们最喜欢的食谱。我们将利用 Edamam API 获取实时食谱数据并将其动态显示在网站上。
食谱查找器允许用户：
src/ │ ├── components/ │ └── Navbar.js │ ├── pages/ │ ├── Home.js │ ├── About.js │ ├── Trending.js │ ├── NewRecipe.js │ ├── RecipeDetail.js │ ├── Contact.js │ └── Favorites.js │ ├── App.js ├── index.js ├── App.css └── index.css
要在本地运行此项目，请按照以下步骤操作：
git clone https://github.com/abhishekgurjar-in/recipe-finder.git cd recipe-finder
npm install
npm start
从 Edamam 网站获取您的 Edamam API 凭证（API ID 和 API 密钥）。
在进行 API 调用的页面中添加您的 API 凭据，例如 Home.js、Trending.js、NewRecipe.js 和 RecipeDetail.js。
import React from "react";
import Navbar from "./components/Navbar";
import { Route, Routes } from "react-router-dom";
import "./App.css";
import Home from "./pages/Home";
import About from "./pages/About";
import Trending from "./pages/Trending";
import NewRecipe from "./pages/NewRecipe";
import RecipeDetail from "./pages/RecipeDetail";
import Contact from "./pages/Contact";
import Favorites from "./pages/Favorites";
const App = () => {
return (
