My source folder:
My dist folder:
The error I get is:
Cannot launch program '/Dev/myapp/server/src/app.ts'; setting the 'outFiles' attribute might help.
If I change the "program" property to ""program": "${workspaceRoot}/dist/server/src/app.js", it works but I'm then debugging the transpiled javascript and not the typescript. Obviously the transpiling with .map files is working, what is wrong?
tsconfig.json

You are missing src folder in your configuration:
"outFiles": [
"${workspaceRoot}/dist/server/src/*.js"
],
Also set your mapRoot in tsconfig.json to ./dist/. Currently it will search your ./server/src folder for sourcemaps instead of ./dist
In my case, I had in launch.json
"program": "${file}"
Which obviously tried to run the ts file in node, when hitting F5 / Ctrl+F5
when changing it to
"program": "${workspaceFolder}/${fileBasenameNoExtension}.js"
allows me to run both active ts and js files...
also launch tsc -watch build task to get js file compiled on the fly

I have a Vue 2.x CLI based project that runs with typescript and vue class components. Here I want to use a package called vueisotope that has no type definition file. To make it work with typescript I changed my tsconfig.json to alternatively search for .d.ts files inside a 'customTypes' folder. I also created a customTypes/vueisotope/index.d.ts file and declared the module. On Ubuntu the project works well but on Windows 10 I still get the following error:
15:24 Could not find a declaration file for module 'vueisotope'. 'node_modules/vueisotope/dist/vue_isotope.min.js' implicitly has an 'any' type.
Try npm install #types/vueisotope if it exists or add a new declaration (.d.ts) file containing declare module 'vueisotope';
I also tried to reference the file as an ambient module but that also doesn't work:
/// <reference path = "../customTypes/vueisotope/index.d.ts" />
Am I doing something wrong here or is it a Windows/TypeScript/IDE issue? How can I bring that to work on a Windows machine?
My tsconfig:
{
"compilerOptions": {
"target": "esnext",
"module": "esnext",
"strict": true,
"jsx": "preserve",
"importHelpers": true,

"tests/**/*.tsx"
],
"exclude": [

}
my index.d.ts:
declare module "vueisotope" {
}
I simply didn't understand the typeRoots part correctly. I also had to define vueisotope inside the types part.
So the working tsconfig would be:

I have a large node js application. It manages HTTP REST requests. It was written in typescript. I am able to compile and run the application without any problem. In VSCode, I have a pre-launch task which basically compiles the code.
When I want to debug the application or try to add breakpoints in it with vscode, it gives me similar error messages like below:
Could not read source map for file:///Users/user/Developer/yoauto/engine/node_modules/#google-cloud/paginator/build/src/resource-stream.js: ENOENT: no such file or directory, open '/Users/user/Developer/yoauto/engine/node_modules/#google-cloud/paginator/build/src/resource-stream.js.map'

It was working yesterday. I do not know the problem. I found the closest issue on github but not sure it's relevant though.
Publish sources and source maps to npm
I think the problem is VSCode itself since I am able to debug the application with the latest webstorm without any problem (might be wrong)
Thanks for your help
Update :
I have downgraded my vscode installation to 1.46.1 from 1.47 and it worked so I am certain that something is not right with vscode 1.47
this seems to be a problem in vsCode like spotted here https://github.com/microsoft/vscode/issues/102042.
To solve it, add those lines to your launch.json config:
"type": "pwa-node",
"resolveSourceMapLocations": [
"${workspaceFolder}/**",
"!**/node_modules/**" // this lines prevent reading source maps from node_modules
],
Tell me if it helps :)
Hi i have built an app using angular-cli and I am trying to debug it using vs code and Debugger for chrome extension. After a while I was able to make it work, well kind of. What happens is that i can set a break-point in my typescript class but it gets placed on a wrong line number like source map is incorrect.
Debug process - open terminal ng serve than go to debug tab and click F5 in vscode
I have the following:

I have updated to angular-cli-beta19-3 and typescript 2.0.6 and cleared cache in chrome now it works.
UPDATE: using angular 2.4.1 now
Whats funny is that it doesnt work with
"sourceMapPathOverrides": {
"webpack:///*": "${webRoot}/*"
}
defined here https://github.com/Microsoft/vscode-chrome-debug
but it works with
"sourceMapPathOverrides": {
"webpack:///C:*": "c:/*"
}
and for linux as #carpinchosaurio said
"webpack:///*": "/*"
UPDATE 2/21/2017:
With new versions of angular and typescript there is no need for source map path overrides anymore.
"#angular/compiler-cli": "2.4.8",
"#angular/cli": "1.0.0-beta.32.3",
"typescript": "2.1.6"
angular version 2.4.8
Working setup:
{
"version": "0.2.0",
"configurations": [
{
"name": "LaunchChrome",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"sourceMaps": true,
"webRoot": "${workspaceRoot}",
"userDataDir": "${workspaceRoot}/.vscode/chrome"
}
]
}
for anyone still interested this worked for me -
{
"name": "Launch localhost with sourcemaps",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"sourceMaps": true,
"webRoot": "${workspaceRoot}/src",
"userDataDir": "${workspaceRoot}/.vscode/chrome",
"sourceMapPathOverrides": {
"webpack:///./~/*": "${workspaceRoot}/node_modules/*",
"webpack:///./src/*": "${workspaceRoot}/src/*"
}
// Uncomment this to get diagnostic logs in the console
// "diagnosticLogging": true
}
Just to emphasize more the updated answer: Currently it's not needed to have the sourceMapPathOverrides property in your launch.json. In case you are updating project from an old Angular, just remove the property and debugging will start working.
I'm trying to get vscode to launch mocha and stop on breakpoints. When I run the tests manually I use the following command:
$ mocha -r node_modules/reflect-metadata/Reflect.js --recursive
I can also use the following command:
mocha -r node_modules/reflect-metadata/Reflect.js --recursive --debug-brk
And the following debug config:
{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to Process",
"type": "node",
"request": "attach",
"processId": "${command.PickProcess}",
"port": 5858,
"sourceMaps": true,
"outFiles": [
"src/**/**.js",
"test/**/**.test.js"
]
}
]
}
This allows me to set breakpoints in the .js files and see the original TypeScript source. But I can't set a break point directly in the TypeScript code.
My second problem is that I would like to simply press debug in the VSCode UI and trigger mocha in debug mode automatically and again hit breakpoints directly in the .ts files.
Is this possible?
I had already a very similar setup as #JasonDent but that didn't work. The node2 setting is already outdated (vscode will warn you). Instead simply add "protocol": "inspector" and voilá breakpoints are hit now:
{
"name": "Mocha",
"type": "node",
"protocol": "inspector",
"request": "launch",
"cwd": "${workspaceRoot}",
"preLaunchTask": "tsc",
"program": "${workspaceRoot}/node_modules/mocha/bin/_mocha",
"args": [ "--no-timeouts", "--colors", "${workspaceRoot}/out/test/**/*.js" ],
"stopOnEntry": false,
"runtimeExecutable": null,
"env": {
"NODE_ENV": "testing"
},
"sourceMaps": true
},
Here's my config based on the latest task building in VSCode. Out the box it doesn't work with Typescript!? Anyway combining the answer from #Jason Dent I was able to get it working! Its also using the newer node2 debugger. For your setup, change the build/test to where ever you have put your files.
{
"type": "node2",
"request": "launch",
// Automatically stop program after launch.
"stopOnEntry": false,
"name": "Mocha Tests",
"cwd": "${workspaceRoot}",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/mocha",
"windows": {
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/mocha.cmd"
},
"runtimeArgs": [
"-u",
"tdd",
"--timeout",
"999999",
"--colors",
"--recursive",
"${workspaceRoot}/build/test"
],
"sourceMaps": true,
"outFiles": ["${workspaceRoot}/build"],
"internalConsoleOptions": "openOnSessionStart",
// Prevents debugger from stepping into this code :)
"skipFiles": [
"node_modules/**/*.js",
"<node_internals>/**/*.js"
]
},
I also recommend a separate launch profile for debugging Mocha tests. I have the following configs, working with Mocha Typescript test.
My launch.json debug mocha profile looks like the following:
{
"type": "node",
"request": "launch",
"name": "Debug tests",
"runtimeExecutable": "mocha",
"windows": {
"runtimeExecutable": "mocha.cmd"
},
"preLaunchTask": "build:tests",
"runtimeArgs": [
"--debug-brk",
"-p",
"tsconfig.test.json",
"test-js/test/index.js"
],
"program": "${workspaceRoot}\\test\\index.ts",
"outFiles": [
"${workspaceRoot}\\test-js\\**\\*.js"
],
"port": 5858
},
build:tests is a vs code task, that runs 'tsc -p tsconfig.test.json'. I had some issues in the past with gulp-typescript sourcemap generation, that's why I'm using TSC at the moment.
My tsconfig.test.json is:
{
"compilerOptions": {
"outDir": "./test-js",
"module": "commonjs",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es2016",
"declaration": true,
"sourceMap": true,
"inlineSources": true
},
"files": [
"./test/index.ts"
]
}
I hope you figured it out by now.
Basic answer, yes you can set breakpoints in .ts files and debug them with VSCode. They have a walk through here on general debugging: Debugging with VSCode
The key part is that you need to make a launch profile explicitly for mocha. This is just an example of how I got it to work. You will need to add something like the following to your .vscode/launch.json.
{
// Name of configuration; appears in the launch configuration drop down menu.
"name": "Run mocha",
// Type of configuration. Possible values: "node", "mono".
"type": "node",
// Request type "launch" or "attach"
"request": "launch",
// Workspace relative or absolute path to the program.
"program": "${workspaceRoot}/node_modules/mocha/bin/_mocha",
// Automatically stop program after launch.
"stopOnEntry": false,
// Command line arguments passed to the program (mocha in this case).
"args": ["--recursive", "lib/*.test.js"],
// Workspace relative or absolute path to the working directory of the program being debugged. Default is the current workspace.
"cwd": "${workspaceRoot}",
// Workspace relative or absolute path to the runtime executable to be used. Default is the runtime executable on the PATH.
"runtimeExecutable": null,
"outDir": "${workspaceRoot}/lib",
"sourceMaps": true,
// Environment variables passed to the program.
"env": { "NODE_ENV": "test"}
}
This will launch mocha to test *.test.js files in the lib directory.
I used the following tsconfig.json file and have my unit tests next to the code:
{
"compilerOptions": {
"target": "es5",
"declaration": true,
"module": "commonjs",
"moduleResolution": "node",
"outDir": "./lib",
"sourceMap": true,
"removeComments": true
},
"include": [
"src/**/*"
],
"exclude": [
"node_modules",
"data",
"lib"
]
}
I need to debug a command gulp start with VScode (I got some mapping error with babel during transpilation that I don't understand yet...). The VSCode debug default configuration aims to launch node app.js. How to modify it to trigger the gulp command?
Here is the default configuration. If anyone has hint of how can I do that, I'll be in your debt :)
{
"version": "0.2.0",
"configurations": [
{
"name": "Lancer",
"type": "node",
"request": "launch",
"program": "${workspaceRoot}/app.js",
"stopOnEntry": false,
"args": [],
"cwd": "${workspaceRoot}",
"preLaunchTask": null,
"runtimeExecutable": null,
"runtimeArgs": [
"--nolazy"
],
"env": {
"NODE_ENV": "development"
},
"externalConsole": false,
"sourceMaps": false,
"outDir": null
},
{
"name": "Attacher",
"type": "node",
"request": "attach",
"port": 5858,
"address": "localhost",
"restart": false,
"sourceMaps": false,
"outDir": null,
"localRoot": "${workspaceRoot}",
"remoteRoot": null
}
]
}
In your "Lancer" configuration, make the following changes.
Change program to "${workspaceRoot}/node_modules/gulp/bin/gulp.js"
Change args to ["start"]
Set a breakpoint in the task you want to debug and launch the debugger. Change 'start' to the desired task name to debug other tasks.
