I want to execute JavaScript code in the Visual Studio Code terminal. I installed the Code Runner extension, but it is executing code in "Output" where I am not able to enter run-time input values.
To execute in "terminal", I have to type "node pgm.js". Is there a way by which I can directly execute JavaScript files in the Visual Studio Code terminal by using shortcut Ctrl + Alt + N?
Go to settings and configure the Code Runner extension to output to the terminal.
Also, you need Node.js for it. If that doesn't work, you don't need code runner. Use Node.js from a normal terminal.
From the top, go to menu View → Terminal to open the normal terminal. Then run the command node filename.js to execute it.

In my vs code when I write javascript and then I clicked run or write node main.js the vs code terminal externally on the new window cannot show any output.
In visual studio code settings I turned off window conpty setting and visual studio code preference settings but It cannot fix. So, How I can run code internally in vs code terminal.
The "gnode" you seem to be running, is not part of the official distribution of NodeJS. Someone similar with your problem (https://github.com/nodejs/help/issues/3670), found a solution by uninstalling whatever he had installed, and reinstalling the LTS version of node (https://nodejs.org/en/download/).
Hi my issue is that in my visual studio code, my code runner extension doesn't provide any output. I've looked at a bunch of tutorials and have done everything, research, download node.js,and saves the file as a javascript file and verify paths.
I entered " console.log("Hello")
Its prints this out
[Running] node "c:\Users\NAME\Untitled-1.js
[Done] exited with code=0 in 0.202 seconds
And nothing
Please help idk what I'm doing wrong 😭
Looks like you haven't saved the file.
Try saving the file and then run with Code Runner.
Tip: You can enable Save before Run settings so that it gets saved every time before running the file.
File -> Preferences -> Extensions -> Run Code Configuration -> Save File Before Run
I recommend you to run node -v and npm -v in command prompt window to see if you have them installed
the output must be like this
C:\Users\Anonymous>node -v
v16.14.0
C:\Users\Anonymous>npm -v
8.3.1
and if there is a problem it might be from your paths ("Edit system environment variables" in windows search) or you haven't installed npm or node.
in my case solution was to uncheck "Show Execution Message" check box in Run Code configuration.

Is it possible to use chrome devtools to execute the terminal command node myfile.js, so the chrome console would output all console.logs from my code?
I have got some terminal plugin installed in my IDE and I use some keyboard shortcuts when I want to run this command on my files, to get my logs immediately (like when running html+js in the browser) but it prints out just plain text. Chrome can recognize the output data type and structurize it well (arrays, objects), what is really cool.
I've already tried out node inspect-brk but its purpose seems to be quite different than just printing out my logs.
UPDATE:
I've found very interesting link with npm modules that do what I mean.
I have alredy tested node-monkey but it does not work on my Windows, but iron-node works great and I can run my .js files with iron-node file.js command and get all console.logs in Chrome devtools!
run your file with
node --inspect <your file name>.js
and then type in chrome
chrome://inspect
See https://nodejs.org/api/debugger.html#debugger_v8_inspector_integration_for_node_js for reference
--inspect-brk is used for breakpoint purposes, with that flag the debugger is ready to run your code but is expecting the developer to add something before it begins to run your script. There is a play button at the top corner of the chrome devtools debugger, and if there are no other breakpoints or debugger; statments in your code it will run as it would run or your workstation
I want to use the node.js on the windows. so I install node but I can't execute a .js file. That is my source code. And I atteched the error screen.
helloworld.js
console.log("Hello, World!")
This error is happening because your script is not executed with nodejs but with Microsoft jscript.
The command you wrote "node node.js" is executing the file ode.js instead of the nodejs in your system in the same way you can execute cmd by typing cmd instead of cmd.exe.
To fix that you need to do one of those :
rename the file to something other than node
move the file named node in a subfolder (i.e. src/node.js)
associate .js file with nodejs instead of microsoft jscript
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.
Use Node.js command prompt, then type in node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js
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
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.
Open CMD.
Type "cd C:\Users\Ankur\Downloads\NodeJS\working" and hit Enter
Type "node hello_world.js" and hit Enter
This should work out !!
IMPORTANT: Dont type node before the point number 3.
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
Alternative.
Open Nodejs "The thing with a green icon".
Copy the code that you would like to be executed from the file that you have
paste it in nodejs then press enter
nodejs understands js code so it will execute what you have written and output
hello world
undefined
What you have descripbed opens the file that you have and then executes it.
Open Windows cmd and type
node C:\Users\Ankur\Downloads\NodeJS\working\hello_world.js
You should use node from system interpreter (bash/DOS cmd), what you are running is C:\Program Files\nodejs\node.exe without any arguments.
