如何在 Node.JS 上运行 index.html

Question

I need to run a website on a server. I installed Node.JS and created a server.js file in the project folder and read the index.html file there. The site opens at the address, but the error in the console is Uncaught SyntaxError: Unexpected token '<'. And the site does not include styles. How can this problem be solved?

 // server.js var http = require("http"); var fs = require("fs"); const PORT = 8080; fs.readFile( "../index.html", function (err, html) { if (err) throw err; http.createServer(function (request, response) { response.writeHeader(200, { "Content-Type": "text/html" }); response.write(html); response.end(); }).listen(PORT); } );

Error:

Answer 1

You are sending the html file in a.js file to the browser. The Problem with the style is caused because you don't send the css file with. You could use ExpressJs to send the whole directory:

Answer 2

if it's a HTML page it must end with.html not.js, change the extension of the file

Answer 3

use express.js, it will be more convenient and easy to use.

const path = require('path');
const express = require('express');
const app = express();
    
app.use((req, res, next) => {
    res.status(404).sendFile(path.join(__dirname, 'views', '404.html'));
});
