Run ts-node in VSCode Debugger

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Example",
      "type": "node",
      "request": "launch",
      "runtimeExecutable": "node",
      "runtimeArgs": ["--nolazy", "-r", "ts-node/register/transpile-only"],

      "args": ["src/script.ts", "--example", "hello"],
      
      "cwd": "${workspaceRoot}",
      "internalConsoleOptions": "openOnSessionStart",
      "skipFiles": ["<node_internals>/**", "node_modules/**"]
    }
  ]
}

node-ter

You saved my life! thx!

ok

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?

Thank you very much. I used your config to be able to debug typescript in neovim using dap.

no type checking and need to use tsconfig-paths to resolve paths

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "runtimeArgs": ["-r", "ts-node/register/transpile-only", "-r", "tsconfig-paths/register"],
            "program": "${workspaceFolder}/packages/lerna/src/cli.js",
            "args": ["version"],
            "console": "integratedTerminal",
            "cwd": "${workspaceFolder}",
            "internalConsoleOptions": "neverOpen",
        }
    ]
}

Error: Cannot find module 'ts-node/register/transpile-only'

fixed this by install ts-node locally

npm link ts-node

// or 

yarn add -D ts-node

@iulo thanks，u save my day.

Works perfectly for me

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "ts-node",
      "type": "node",
      "request": "launch",
      "args": ["${relativeFile}"],
      "runtimeArgs": ["-r", "ts-node/register"],
      "cwd": "${workspaceRoot}",
      "protocol": "inspector",
      "internalConsoleOptions": "openOnSessionStart"
    }
  ]
}

Not all heroes wear capes! 😀

Thanks!
General purpose ts-node run opened file (using ${file}) whereas process-library is the base-folder of the ts app:

Wow, I have never had a VS Code debug configuration work perfectly the first time I ran it. Thanks a bunch

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?
