CDK Debugging on VSCode

README.md

Install

Place launch.json file in .vscode/ directory in the root of your CDK application

It assumes the entry point of your CDK app is in bin/app.ts.

Adjust args attribute accordingly if you use something else.

Run

Use VSCode debug mode, running the Debug CDK configuration

Tested with CDK versions 1.89.0 and 1.101.0, so any version between those two should work just fine

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug CDK",
      "type": "node",
      "request": "launch",
      "skipFiles": ["<node_internals>/**"],
      "runtimeArgs": ["-r", "./node_modules/ts-node/register/transpile-only"],
      "args": ["${workspaceFolder}/bin/app.ts"]
    }
  ]
}

if you have nvm installed, include
"runtimeVersion": "12.20.1" in configurations property of launch.json like below:
{
"version": "0.2.0",
"configurations": [

  {
  "type": "node",
  "request": "launch",
  "name": "Launch Program",
  "skipFiles": [
      "<node_internals>/**"
  ],
  "runtimeVersion": "12.20.1",
  "runtimeArgs": [
      "-r", "./node_modules/ts-node/register/transpile-only"
  ],
  "args": [
      "${workspaceFolder}/bin/cdk-try.ts"
  ]
  }

]
