Unknown Encoding Error in Node.js

Question

I am new to Node.js and stuck on an error which is irritating me from 2 days!

The JS looks like this:

var http = require('http');
var fs = require('fs');

var server = http.createServer(function(req, res) {
 console.log("A request was made of url : " + req.url);
 res.writeHead(200, { 'Content-Type': 'text/html' });
 var data = fs.createReadStream(__dirname, '/index.html', 'utf8');
 data.pipe(res);
});
server.listen(4242);
console.log("Server is running.....");

And this is the HTML file:

<!DOCTYPE <html>
<html lang="en">

<head>
<meta charset="UTF-8">
<title>Index Website</title>
</head>

<body>
<h1>Some HTML</h1>
</body>

</html>

But I end up getting this error:

string_decoder.js:13
throw new Error(`Unknown encoding: ${enc}`);
^

Error: Unknown encoding: /index.html
at normalizeEncoding (string_decoder.js:13:11)

at emitTwo (events.js:106:13)
at Server.emit (events.js:191:7)

Can someone tell me what went wrong, or point me in the right direction?

fs.createReadStream takes parameters fs.createReadStream(path[, options]) so for your case you should write it like fs.createReadStream(`${__dirname}/index.html`, {encoding: 'utf8'}) — Prasanna

fs.createReadStream takes parameters

fs.createReadStream(path[, options])

so for your case you should write it like

fs.createReadStream(`${__dirname}/index.html`, {encoding: 'utf8'})

for the use __dirname you should;

first join the path

const indexPath = path.join(___dirname, "index.html");

then

const data = fs.createReadStream(indexPath, 'utf8');
