Hi everyone! How to deal with typescript paths? It does not recognize imports that are described in tsconfig.json Tried to use NPM package to register paths, but it does not work.

"args": ["${workspaceFolder}/cli/index.ts", "-r", "tsconfig-paths/register"],
"runtimeArgs": ["--nolazy", "-r", "ts-node/register", "-r", "tsconfig-paths/register"],

I am having a strange problem with breakpoints. The debugger never stops at selected breakpoints no matter what. Anyone know how to fix this ?

This is great, thx!!
In my case though there's still a pending issue: How to add non-global nodemon into the mix.

@ehaynes99

@ArnieGA It took me a while to figure out, so thought I would post it here: https://gist.github.com/ehaynes99/4218666a38984d1c3d544076b49d9439

This uses ts-node to debug, with or without nodemon, without having to install anything.

Sorry, this didn't work on my end. My repo contains projects that implement typescript references + paths and those weren't picked up using your method. But that's ok, I went back to the combination that worked for me, which is using a nodemonConfig key plus the start script to achieve what I needed (which does require nodemon to be installed, locally):

node-project/package.json

"nodemonConfig": {
    "exec": "node -r tsconfig-paths/register -r ts-node/register",
    "ext": "ts",
    "ignore": [
        ".git",
        "node_modules"
    ],
    "watch": [
        "./src",
        "../repo-project-1/models",
        "../repo-project-2/src"
    ]
},
"start": "env-cmd -f ./.env.development nodemon src/main.ts"

.vscode/launch.json

{
  "type": "node",
  "request": "launch",
  "name": "Node Project",
  "skipFiles": [
    "<node_internals>/**",
    "node_modules/**"
  ],
  "runtimeExecutable": "npm",
  "runtimeArgs": [
    "start"
  ],
  "outputCapture": "std",
  "cwd": "${workspaceFolder}/node-project",
  "internalConsoleOptions": "openOnSessionStart",
  "stopOnEntry": false,
  "preLaunchTask": "Start Mongo Server",
  "postDebugTask": "Terminate Tasks"
}

This method allowed me to use typescript references + paths, and the ability to pick how to start the project (via debugger or terminal).

I'm getting "unknown file extension" for file "main.ts"

@mrjbj This happens if you're working with an ES Module (a project with a "type": "module" in its package.json-file).
You can find the arguments required for using ESModules in ts-nodes README: https://github.com/TypeStrong/ts-node/tree/8b09d49b26c1c25e34133b857c073729dd691f11#node-flags-and-other-tools

tl;dr-version

For running ESModules using ts-node you might want to use a task-configuration looking like this:

{
    "type": "node",
    "request": "launch",
    "name": "Launch ESModule TypeScript File",
    "cwd": "${workspaceFolder}",
    "runtimeArgs": [
        "--loader",
        "ts-node/esm"
    ],
    "program": "{ Path to Your `.ts` File}"
}

For me it worked after removing /transpile-only from this line

"runtimeArgs": ["--nolazy", "-r", "ts-node/register/transpile-only"],

 "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Server",
      "cwd": "${workspaceFolder}",
      "runtimeArgs": [
        "--loader",

        "--experimental-specifier-resolution=node"
      ],
      "program": "${workspaceFolder}/src/index.ts"
    }

Hope this helps someone 🍻

I have literally wasted two evenings trying to get my typescript running under VSCode (even though it runs fine using ts-node) - I was just about to throw in the towel and spend the rest of the evening screaming at the moon...

I've had the following config working forever without issue, but after upgrading to typescript 5 and apollo server 4, all of the sudden it doesn't like it anymore...

{ "version": "0.2.0", "configurations": [ { "name": "Server", "type": "node", "request": "launch", "runtimeExecutable": "node", "runtimeArgs": ["--nolazy", "-r", "ts-node/register/transpile-only"], "resolveSourceMapLocations": ["${workspaceFolder}/**", "!**/node_modules/**"], "args": ["src/index.ts"], "env": { "NODE_ENV": "local" }, "cwd": "${workspaceRoot}", "internalConsoleOptions": "openOnSessionStart", "skipFiles": ["<node_internals>/**", "node_modules/**"] } ] }

I end up getting this, which looks like it's not skipping the node_modules like it should
/node_modules/@apollo/server/dist/cjs/ApolloServer.js:70 const nodeEnv = config.nodeEnv ?? process.env.NODE_ENV ?? '';

Anyone else seen anything like this?

Unfortunately, this does not work with "console": "internalTerminal", I'm getting Cannot find module ts-node/register/transpile-only. (ts-node is installed locally as a dev dependency - I tried everything, deleting node_modules, restarting..).

With "console": "externalTerminal" it seems to work.

Any idea why this has to do with the "console" setting?
