I'm trying to set up a distant debug with VS Code on a node.js (7.1.0) project.
I launch my dev app with pm2:
{
"apps": [{
"name": "my-app-dev",
"script": "app.js",
"watch": true,
"node_args": ["--inspect=9229", "--nolazy"],
"ignore_watch": ["assets/images/", ".tmp/", ".git/"],
"watch_options": {
"usePolling": true
}
}]
}
this is the .vscode/launch.json file:
{
"version": "0.2.0",
"configurations": [
{
"type": "node2",
"request": "attach",
"name": "attach",
"port": 9229,
"address": "my.app.local",
"restart": true,
"diagnosticLogging": true,
"sourceMaps": false
}
]
}
When I start the debugger I successfully get attached Debugger attached.
The problem is my breakpoints are getting ignored: Unverified breakpoint
finally found a solution by adding
"localRoot": "${workspaceRoot}/api",
"remoteRoot": "/srv/www/my-app/api"
to my launch.json.
If someone can explains why its needed :o

I have an Angular application that I am trying to debug in VS Code. When I write code in a particular .ts file and put a breakpoint on a method or statement, it is bound. But when I try to debug through Run > Start Debugging, the breakpoint becomes unbound. Once debugging starts, nothing happens afterwards. Neither does it hit the breakpoint, nor do the buttons (Step Over, Step Into, Run, etc.) of the floating debugging toolbar at the top get enabled. I followed this and this videos, and tried almost everything mentioned in this thread. But nothing solved my problem. I even upgraded node.js 17 to 18, yet of no avail. I tried multiple browsers like Edge, Chrome, Firefox and Opera. Debugging happens nowhere. So, what to do now to get VS Code debugging up and running? Because otherwise it is too cumbersome to use console.log(); every time to debug.
Please ask me if you need any more info of my code.
My environment:
OS - Windows 10
VS Code - 1.73.1
Node.js - 18.12.1
Angular CLI - 14.2.6

I am trying to debug nodejs code using Launch.json attach to process. I have tried following configuration
but debugger is not getting connected. my application is running on Node v6.11.5
Launch.json :--
{
"type": "node",
"name": "Attach by Process ID",
"request": "attach",
"processId": "${command:PickProcess}",
"skipFiles": [
"<node_internals>/**"
],
}
,Error getting displayed:
If you are using gulp you can use a configuration like this to launch the gulp task from VSCode using the Run->Start Debugging F5 command and debug it directly.
{
"version": "0.2.0",
"configurations": [
{
"name": "MyGulpTask",
"type": "node",
"request": "launch",
"program": "${workspaceRoot}/node_modules/gulp/bin/gulp.js",
"stopOnEntry": false,
"args": [],
"cwd": "${workspaceRoot}",
"runtimeArgs": [
"--nolazy"
],
"console": "internalConsole",
}
]
}
I want to use Visual Studio for developing an Node.js application with Typescript and simply want the normal debug behavior of any modern IDE: Debug code, set breakpoints, look into vars etc. Following the official documentation guide, I get an error when running the task: The npm task typescript didn't contribute a task for the following configuration.
So instead I invoke a custom npm script in the tasks.json file:
launch.json
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Attach",
"port": 9229,
"preLaunchTask": "typescript"
}
]
task.json
"tasks": [
{
"type": "shell",
"label": "typescript",
"command": "cd server; npm run build:live"
},
]
package.json
"scripts": {
"build:live": "nodemon --inspect --exec ./node_modules/.bin/ts-node -- ./index.ts"
}
Now the app is comping and starting (also with live reloading) fine. But NO debugging works, no breakpoint was reached. Is it really that hard to debug Typescript in VS Code?
I'm using the latest
Live debugging seems to be a pain on Typescript in VS Code. I could only make regular debugging working in a similar way to the full Visual Studio:
launch.json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"program": "${workspaceRoot}/index.ts",
"outFiles": [
"${workspaceRoot}/dist/**/*.js"
],
"sourceMaps": true,
"stopOnEntry": false,
"cwd": "${workspaceRoot}",
"env": {
"NODE_ENV": "development"
},
"console": "integratedTerminal",
"internalConsoleOptions": "openOnFirstSessionStart",
"preLaunchTask": "compile",
"name": "DEBUG"
}
]
}
tasks.json
{
"version": "2.0.0",
"tasks": [
{
"label": "compile",
"type": "typescript",
"tsconfig": "tsconfig.json",
"problemMatcher": [
"$tsc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
Please note that you've to set "sourceMap": "true" in tsconfig.json. When not, an error occurs that corresponding source maps aren't found. This is cause NodeJS isn't able to compile TS. Compiling is done by the TypeScript compiler tscbefore. For debugging purpose (e.g. reach breakpoints) the source maps can map the compiled js to the ts source file here.
Loving Grommet and vscode. Trying to get them to play together. I am able to get Express and vscode working as shown here. I would like to get the grommet-cli sample app to work similarly. Express has one command to start: "npm start" where grommet-cli has two: "npm run dev-server" and "npm run dev" (not sure how to start them both in vscode. I think I may need multi-session debugging?). How do I setup launch.json to debug the sample app? I'd like to be able to debug in IE/Edge. I've had some success in Chrome with the Debugger for Chrome extension.
Here is my current launch.json:
{
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:3000",
"webRoot": "${workspaceRoot}"
},
{
"type": "chrome",
"request": "attach",
"name": "Attach to Chrome",
"port": 9222,
"webRoot": "${workspaceRoot}"
}
]
}
This appears to resolve the issue. Hopefully, it's been added to the latest version of VS.

I am trying to debug mocha unit test in visual studio code. I followed this question and got this run configuration:
{
"name": "Run mocha",
"type": "node",
"program": "/usr/bin/mocha",
"stopOnEntry": false,
"args": ["testUtils.js"],
"cwd": "${workspaceRoot}",
"runtimeExecutable": null,
"env": { "NODE_ENV": "development"}
},
It works. But it does not stop at breakpoints! If I run the file with a normal launch configuration, breakpoints are not ignored.
Any Idea what could be the reason for this?
This works for me, you need to point to _mocha. Using just mocha does not allow attaching breakpoints.
{
"name": "Debug mocha",
"type": "node",
"request": "launch",
"runtimeArgs": ["C:\\Users\\CS\\AppData\\Roaming\\npm\\node_modules\\mocha\\bin\\_mocha"],
"program": "${workspaceRoot}\\test.js",
"stopOnEntry": false,
"args": [
],
"cwd": "${workspaceRoot}",
"runtimeExecutable": null,
"env": {
"NODE_ENV": "development"
}
}
If you include the port and the "--debug-brk" argument, you should be able to debug mocha unit tests. I have the following setup in my launch.json file. I included the "--recursive" argument as well so mocha would run all tests in subfolders as well. With this configuration file, I just set my VS Code debugger to use the "Debug Mocha Test" configuration and I'm able to hit breakpoints in any of my test files.

}
You can verify the port mocha will use for debugging by running mocha --debug-brk
