package.json 文件是 Node.js 项目的重要部分。它包含项目的元数据以及项目依赖项的配置详细信息。

以下是 package.json 文件的关键组成部分:

"name": "lr_grepjs"
"version": "1.0.0"
"description": "A grep-like CLI app in Node.js"
"main": "lib/lr_grep.js"
"scripts": {
  "test": "mocha test/*.js",
  "start": "node lib/lr_grep.js"
}

在这个例子中,运行 npm test 将使用 Mocha 执行测试,而 npm start 将运行你的 CLI 应用程序。

}
