Debugging with VSCode¶

In VSCode, install Duktape Debugger extension.
Create a WhaleJS project as described in Getting started.
Open your project folder in VSCode.

Create “Duktape JS” debug configuration. Make sure you select debug port 26972.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach (duk)",
      "type": "duk",
      "request": "attach",
      "address": "localhost",
      "port": 26972,
      "localRoots": [
        "${workspaceRoot}"
      ],
      "sourceMaps": false,
      "outDir": null,
      "stopOnEntry": true,
      "debugLog": false
    }
  ]
}

Run your project with whalejs-dbg.
```
$ whalejs-dbg [path to project directory]
```
It will start the project in debug mode, and wait for debugger to attach.
In VSCode, run your Duktape JS debug session. Debugger will attach to already running whalejs-dbg process.

Now you should be able to put breakpoints and step through your code in VSCode debugger.
