如何从高于我的服务器文件夹级别的目录在 Express 中提供 HTML 文件？

Question

I am trying to serve an HTML file which is in my main directory, through my Express server which is one level deeper: in my server folder. This is how the server code is set up:

 const express = require('express'); const app = express(); app.use(express.json()); app.get('/', (req, res) => { res.sendFile(__dirname + '/index.html'); }) const port = 5000; app.listen(port, () => console.log(`Server is listening on port ${port}.`))

The error I am receiving is:

Error: ENOENT: no such file or directory, stat '/mnt/c/Project-Directory/server/index.html'

It is clear from this error why I am not able to access my HTML file; my server exists in the /server folder and my index.html file exists in the Project-Directory folder. However, I am not sure how to access my HTML file in its current directory.

You can use path.join and specify that you want one directory back ( ../ ):

const path = require('path');


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