# VSCode Node.js Typescript Debugging

### Debugging ts-node

First create your `launch.json` ( [visual studio code doc](https://code.visualstudio.com/docs/typescript/typescript-debugging) )

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

{% code title=".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/**"]
    }
  ]
}

```

{% endcode %}

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