VSCode Node.js Typescript Debugging

Debugging ts-node

First create your launch.json ( visual studio code doc )

To allow breakpoints to work, we need to enable source maps in our launch.json as shown below:

.vscode/launch.json

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

      "args": ["${file}", "--sample-arg", "test"],

      "cwd": "${workspaceRoot}",
      "internalConsoleOptions": "openOnSessionStart",
      "skipFiles": ["<node_internals>/**", "node_modules/**"]
    }
  ]
}

Then get back to your file, and start the debugger.
