How to execute a hello world javascript file in node.js

Question

I have hello_world.js file located on my computer at the following location -

C:\Users\Ankur\Downloads\NodeJS\working

It has the following code-

console.log("Hellow World");

I was reading a beginners tutorial here and it says I should execute my javascript file through node.js. Now I have no idea what to do. How would I do this.

When I do this ...

I get nothing. What should I be doing to run the hello world successfully. None of the tutorials seem to be showing what needs to be done.

I am very new to this so it is probably something that is very obvious to you guys.

Solution 1

Use Node.js command prompt, then type in node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js

Solution 2

looks like you are in a node console already. you typed node which correctly started node (so your path is fine). Now you are telling node to interpret

node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js

as javascript which it doesn't like.

You should be able to type console.log('hello world'); here and see it appear.

To run your file, quit out of the node interpreter (i think control-X, maybe control-C), and at your C:> prompt, THEN type

node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js

Alternately,

cd C:\Users\Ankur\Downloads\NodeJS\working\
node hello_world.js

Solution 3

You have entered the node console, by typing node into a command prompt, and then tried to execute node from within itself. Just type node c:\etc\...\ from the command prompt, not the node shell.

Press: [Start]->[Run]->[c][m][d]

And enter command: node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js

Alternatively, use sublime editor, and install a node js build system, and just open the file you want to run, and press the build shortcut, getting the output in the console.

Solution 4

Follow these three easy steps:

• Go to your working directory

  C:\Users\Ankur\Downloads\NodeJS\working 
  

• Open cmd there and type

  node hello_world
  

• Press Enter

Solution 5

1. Open CMD.
2. Type "cd C:\Users\Ankur\Downloads\NodeJS\working" and hit Enter
3. Type "node hello_world.js" and hit Enter

This should work out !! IMPORTANT: Dont type node before the point number 3.
