Express 应用生成器
使用应用生成工具 express-generator 快速创建应用骨架。
🌐 Use the application generator tool, express-generator, to quickly create an application skeleton.
你可以使用 npx 命令运行应用生成器(在 Node.js 8.2.0 中可用)。
🌐 You can run the application generator with the npx command (available in Node.js 8.2.0).
$ npx express-generator对于较早的 Node 版本,将应用生成器作为全局 npm 包安装,然后启动它:
🌐 For earlier Node versions, install the application generator as a global npm package and then launch it:
$ npm install -g express-generator$ express使用 -h 选项显示命令选项:
🌐 Display the command options with the -h option:
$ 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,以下命令将创建一个名为 myapp 的 Express 应用。该应用将会被创建在当前工作目录下名为 myapp 的文件夹中,并且视图引擎将被设置为 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然后安装依赖:
🌐 Then install dependencies:
$ cd myapp$ npm install在 MacOS 或 Linux 上,使用以下命令运行应用:
🌐 On MacOS or Linux, run the app with this command:
$ DEBUG=myapp:* npm start在 Windows 命令提示符下,使用此命令:
🌐 On Windows Command Prompt, use this command:
> set DEBUG=myapp:* & npm start在 Windows PowerShell 上,使用此命令:
🌐 On Windows PowerShell, use this command:
PS> $env:DEBUG='myapp:*'; npm start然后,在浏览器中加载 http://localhost:3000/ 以访问应用。
🌐 Then, load http://localhost:3000/ in your browser to access the app.
生成的应用具有以下目录结构:
🌐 The generated app has the following directory structure:
.├── app.js├── bin│ └── www├── package.json├── public│ ├── images│ ├── javascripts│ └── stylesheets│ └── style.css├── routes│ ├── index.js│ └── users.js└── views ├── error.pug ├── index.pug └── layout.pug
7 directories, 9 filesNote
由生成器创建的应用结构只是组织 Express 应用的众多方式之一。随意使用此结构或根据需要进行修改,以最适合你的需求。
🌐 The app structure created by the generator is just one of many ways to structure Express apps. Feel free to use this structure or modify it to best suit your needs.
