Express 生成器

使用应用程序生成器工具 express-generator 快速创建应用程序骨架。

您可以使用 npx 命令（在 Node.js 8.2.0 中可用）运行应用程序生成器。

$ npx express-generator

对于较早的 Node 版本，将应用程序生成器安装为全局 npm 包，然后启动它：

$ npm install -g express-generator
$ express

显示带有 -h 选项的命令选项：

$ express -h

  Usage: express [options] [dir]

  Options:

    -h, --help          output usage information
        --version       output the version number
    -e, --ejs           add ejs engine support
        --hbs           add handlebars engine support
        --pug           add pug engine support
    -H, --hogan         add hogan.js engine support
        --no-view       generate without view engine
    -v, --view <engine> add view <engine> support (ejs|hbs|hjs|jade|pug|twig|vash) (defaults to jade)
    -c, --css <engine>  add stylesheet <engine> support (less|stylus|compass|sass) (defaults to plain css)
        --git           add .gitignore
    -f, --force         force on non-empty directory

例如，以下创建一个名为 myapp 的 Express 应用程序。该应用程序将在当前工作目录中名为 myapp 的文件夹中创建，并且视图引擎将设置为 Pug：

$ express --view=pug myapp

   create : myapp
   create : myapp/package.json
   create : myapp/app.js
   create : myapp/public
   create : myapp/public/javascripts
   create : myapp/public/images
   create : myapp/routes
   create : myapp/routes/index.js
   create : myapp/routes/users.js
   create : myapp/public/stylesheets
   create : myapp/public/stylesheets/style.css
   create : myapp/views
   create : myapp/views/index.pug
   create : myapp/views/layout.pug
   create : myapp/views/error.pug
   create : myapp/bin
   create : myapp/bin/www
