推荐答案

要提供静态文件(例如图像，CSS文件和JavaScript文件)，请使用Express中内置的express.static内置中间件功能.

To serve static files such as images, CSS files, and JavaScript files, use the express.static built-in middleware function in Express.

将包含静态资产的目录的名称传递给express.static中间件函数，以开始直接提供文件.

Pass the name of the directory that contains the static assets to the express.static middleware function to start serving the files directly.

示例:-使用以下代码在名为public的目录中提供图像，CSS文件和JavaScript文件:

Example:- Use the following code to serve images, CSS files, and JavaScript files in a directory named public:

app.use(express.static('public'));

现在，您可以加载公共目录中的文件:

Now, you can load the files that are in the public directory:

http://localhost:3000/images/kitten.jpg
http://localhost:3000/css/style.css
http://localhost:3000/js/app.js
http://localhost:3000/images/bg.png

此后，脚本将成功加载.

After this your script will be loaded successfully.

<script type="text/javascript" src="js/jquery-2.1.4.js"></script>
