res.end('Hello World\n');
}).listen(8080, 'localhost');
console.log('Server running at http://localhost:8080/');
can anyone help me in this
This is probably because you are running your script as if it is a bash script.
You have two options
run your program with the command $ node your_pgm.js
add the line #!/path/to/node to the beginning of your program (it must be the very first line)
Why are you typing in bash?
Please try to type "$ node" first and then you should see:
Welcome to Node.js v14 (or any version that you have installed).

I have the below code in Nodejs and tried to execute the same through command line as well as in browser, but getting "unexpected identifier" error.
var http = require('http');
http.createServer(function(request, response) {
response.writeHead(200, {'Content-Type': 'text/html'});
response.end('<b>Running in server...</b>');
}).listen('3000', '127.0.0.1');
File name created is module3.js
I am very new to nodejs. So can anyone please help me to resolve this. Thanks!!
If you like to run file, do it as usual for shell comman line (interpreter file):
D:\nodejs> node module3.js
If you like to work in nodejs command line, you need to load module by require and it will be loaded and evaluated:
D:\nodejs> node
> require('./module3')
If your module exports some function you may to call it:
D:\nodejs> node
> require('./module3')()
Check about exports here
I am trying to set up nodejs with atom on ubuntu 16.10. I followed the steps given in this link. But when I edit the ~/.atom/config.cson file to
runner:
scopes:
js:”nodejs”
as given in the link, Atom gives an error
Unexpected new line after runner:
How do I get this correct?
EDIT
After using Dan Lowe's code, the atom error disappeared but the code doesnt compile.
#!/usr/bin/env nodejs
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(8080, 'localhost');
console.log('Server running at http://localhost:8080/');
It gives the error
./server.js: line 3: syntax error near unexpected token `('
./server.js: line 3: `var http = require('http');'
Is it not able to see nodejs?
If this is the actual config you are using, you have two problems.
The lines are not indented.
Around nodejs are smart-quotes, not normal double quotes. That is not valid syntax here.
You probably want this instead.
runner:
scopes:
js: "nodejs"
I am trying to learn node.js and like many others, the first step is like How to run server written in js with Node.js
However, my problem is syntax problem? (as follows)
server.js
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');
That's a different program called Node. You may want to uninstall it, then install actual Node from here:https://nodejs.org/en/download/
When I type in node example.js to my command prompt it gives me an error message.
This is the code I'm using.
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, 'localhost');
console.log('Server running at http://localhost:1337/');
I got that directly from the node.js website and it worked last night. It won't work today. Some help would be appreciated please.
Node.js looks for the file you pass it in the current directory.
If the file only exists in a different directory, it will not be able to find it.
You need to either save the file to the correct directory, or use cd to switch to the directory containing the file.
from my understanding I need to create a file called server.js and then paste this code in it
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');
Where do I put this file?
I know where the node_modules folder is but I am not sure where to sit this server.js file.
You can put the server file anywhere that you want. Once you've done that, open Command Prompt or Terminal and enter this command:
cd C:\the\full\path\to\the\file\server.js
but, of course, enter the correct path to the server.js. After that, you should enter the command:
node server.js
And the server will start!
