Building Recipe Finder Website using React

介绍

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。

项目概况

食谱查找器允许用户：

  • 按名称搜索食谱。
  • 查看趋势和新添加的食谱。
  • 查看各个食谱的详细信息。
  • 将食谱添加到收藏夹列表并使用 localStorage 保存数据。

特征

  • 搜索功能：用户可以通过输入查询来搜索食谱。
  • 热门食谱：显示来自 API 的当前热门食谱。
  • 新菜谱：显示来自 API 的最新菜谱。
  • 食谱详细信息：显示有关所选食谱的详细信息。
  • 收藏夹：允许用户将食谱添加到收藏夹列表，该列表保存在本地。

使用的技术

  • React：用于构建用户界面。
  • React Router：用于不同页面之间的导航。
  • Edamam API：用于获取食谱。
  • CSS：用于设计应用程序的样式。

安装

要在本地运行此项目，请按照以下步骤操作：

  1. 克隆存储库： 
   git clone https://github.com/abhishekgurjar-in/recipe-finder.git
   cd recipe-finder
  1. 安装依赖项： 
   npm install
  1. 启动 React 应用程序： 
   npm start

  1. 从 Edamam 网站获取您的 Edamam API 凭证（API ID 和 API 密钥）。

  2. 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。
