如何使用 nodejs 中的 express 渲染带有侧 js 文件的 HTML 文件？

Question

I have a index.html file, which i want to send, using

app.get('/', (req, res) => { res.sendFile(`${__dirname}/index.html`) });

Also, I have some js files in this directory, which I want to use in HTML by

<script src="./js/index.js"></script>

So, how can I make these js files accessible in HTML?

Answer 1

You can use what @fedeteka suggested.

app.use('/js', express.static('js'));

The example above basically makes any file in the js folder to be accessed by the /js path. For example, if you have your file tree set up like

Main Folder
-----js
----------script.js
----------another.js
----------asmanyasyouwant.js

These files can be accessed by going to localhost:{yourport}/js/script.js or localhost:{yourport}/js/another.js , etc.

If you set it up this way, you can have

<script src="/js/index.js"></script>

as long as you have a file called index.js in the js folder.
