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/**"]
    }
  ]
}

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! 😀
