VSCode Debugger pauses unexpectedly in node modules files - node.js

While running my nodejs server code through the VSCode Debugger it pauses weirdly in multiple node module library files. Then I just have to hit play button like a hundred times to finally run the whole code. This is so annoying. I have no idea how to fix it. I even tried skipping node module files and folder in launch.json file but it just doesn't seem to work. Below is my launch.json file.
{
// Use IntelliSense to learn about possible Node.js debug attributes.

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${file}",
"cwd": "${workspaceRoot}",
"skipFiles": [
"${workspaceRoot}/node_modules/**/*.js",
"<node_internals>/**/*.js"
]
},
{
"type": "node",
"request": "attach",
"name": "Attach to Process",
"address": "localhost",
"port": 5858
}
]
}

uncheck them and it will work smoothly

Visual Studio Code Opening in Browser

I downloaded VSC and recently for a course I opened jupyter notebook in ubuntu. Now when I try running my programs in VSC it keeps opening the browser in chrome and says "This site can't be reached: local host failed to connect". I looked at some websites and they said to delete
"action": "openExternally",
"pattern": "^\\s*Now listening on:\\s+(https?://\\S+)"
},
from the launch:json file. But when I open the launch.json file it says
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",

"name": "Launch Chrome against localhost",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}"
}
]
}
Could someone please help me?
Thank you for your time
Just get rid of (or comment out) this entire section.
"type": "pwa-chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}"
This is instructions to open chrome, so if you remove it, chrome won't open on run.

Node Debugging in WSL

I am using Windows 10 WSL in VSCode.
I have the extensions remote development, WSL, I have node installed, nvm as well.
When in work in a remote WSL and try to debug I don't have the Node option at all.
When I run the file I get:
No debugger available, can not send 'variables'
My launch.json is as follows:
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"skipFiles": [
"<node_internals>/**"
],
"program": "${file}"
}
]
}```
Can someone please help me fix it by adding Node.js option so I can properly debug?
Thanks a lot in advance!
Did you found the solution eventually?
I add similar issue, I could get things working only by specifying the node binary path explicitly.
get your node binary path by issuing:
which node
then add it to your launch.json config:
{
"name": "Launch Program",
"program": "${workspaceFolder}/helloworld.js",
"request": "launch",
"skipFiles": [
"<node_internals>/**"
],
"type": "pwa-node",
"runtimeExecutable": "/home/user01/.nvm/versions/node/v14.18.0/bin/node"
},
Still there is something is wrong going on, even though I simply the setup tutorial:

VSCode Nodejs debugger does not save changes?

I am just starting to learn using the Nodejs debugger. It has been really helpful already but I spent a a lot of time changing a js file I was debugging but I did not know that the changes I made were not being implement right away.
Is this an expected behavior? Can I set the debugger up so that it restarts on each save and notices the new changes?
Edit 1 :
Here is my debuf config:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"skipFiles": [
"<node_internals>/**"
],
"program": "${workspaceFolder}\\app.js"
}
]
}
Normally, after every save, you have to restart your node program to see the changes. I'm sure there are other programs but one I use exclusively (I never use node alone) is nodemon. It's globally installed npm package program. Here is sample config for vs code debugger:
{
"type": "node",
"request": "launch",
"name": "Launch app - nodemon",
"runtimeExecutable": "nodemon",
"runtimeArgs": [
"--inspect=9250"
],
"program": "${workspaceRoot}/api/app",
"cwd": "${workspaceRoot}/api",
"autoAttachChildProcesses": true,
"restart": true
},
nodemon will monitor all the files and restart node every time it detects changes.
Add runtimeArgs to change debugger port.

Can i skip node internal modules in nodejs debugging while using visual studio code? [duplicate]

When debugging in vscode I'd like to make some "blackboxing" and do not enter into code I didn't write. How can I do this?
In your launch or attach debug task you can enter a
"skipfiles"
option which is
"An array of file or folder names, or path globs, to skip when debugging."
For example, from skipping node internals during debugging
"skipFiles": [
"${workspaceFolder}/node_modules/**/*.js",
"${workspaceFolder}/yourLibToSkip/**/*.js"
]
Also, there is a "magic reference" to the built-in core node modules you can use:
"skipFiles": [
"<node_internals>/**/*.js"
]
I was confused on where to put the setting, so just in case, if you want to skip both node_modules deps and node_internals files, your .vscode/launch.json file should look something like this:
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Tests",
"type": "node",
"request": "launch",
...
"skipFiles": ["<node_internals>/**", "${workspaceFolder}/node_modules/**/*.js"]
}
]
}
Only this worked for me.
"debug.javascript.terminalOptions": {
"skipFiles": [
"<node_internals>/**"
]
}
Just to amplify on Mauro Aguilar's correct answer, here are the complete contents of my launch.json file. Note that I am debugging a ReactJS app (circa 2021) with VS Code 1.60.2 on Windows 10 using Chrome v.94. If you're using a Linux machine or a Mac, YMMV.
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "pwa-chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:3000",
"webRoot": "${workspaceFolder}",
"skipFiles": ["<node_internals>/**/*.js", "${workspaceFolder}/node_modules/**/*.js"]
},
]
}
this is my launch.json file (it works for me):
{
"version": "0.2.0",
"configurations": [
{
"type": "edge",
"request": "launch",
"name": "Launch Edge against localhost",
"url": "http://localhost:4200",
"webRoot": "${workspaceFolder}",
"skipFiles": [
"${workspaceFolder}/node_modules/**/*.js"
]
}
]
}
For flutter apps, add to your user settings the following:
"dart.debugExternalLibraries": false,
"dart.debugSdkLibraries": false,
For some reason, I've needed to add both types of skip file entries,
"skipFiles": [
"${workspaceFolder}/node_modules/**/*.js",
"<node_internals>/**"
],
This seems to have resolved the issue.
"dart.debugExternalLibraries": false,
"dart.debugSdkLibraries": false,
If I add this, the debug stop after a few steps into
For Typescript built with Webpack, I had to put the exclusions in launch.json - putting them in settings.json/terminalOptions had no effect.
Also, I had to exclude the pattern of the generated files, not the source files. In my case it looks like:
"skipFiles": [
"<node_internals>/**",
"**/vendors-*",
],

Debug/Run in vscode: Program exists

I have an express.js app.
Whenever I try to debug/run it in vscode, it just runs through and exists. How do I keep this process alive just like it normally does? Or is something wrong with my config?
No errors whatsoever are thrown.
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "www",
"runtimeExecutable": "npm",
"runtimeArgs": [
"run-script",
"www"
],
"address": "localhost",
"port": 5000,
"stopOnEntry": false,
"cwd": "${workspaceRoot}",
"env": {
...
}
}
]
My npm-script looks like this:
flow-node www/index.js
I want to debug/run this script from vscode since I have a lot of env-variables and, obviously, for debug-reasons.
You may just need to specify the program attribute of the launch.json config.
program - executable or file to run when launching the debugger
