Basically what I do when I want to see whats happening is I put a console.log wherever I need it.. If you want to debug the angular app, you need to have the angular dev server running, preferably concurrently with the backend server - for that purpose, run "npm run watch" - then, you put a console.log in the angular component or in some controller/resolver handler.. Heres an example:

Hi,

Consider adding a launch setting for vscode, for example:

launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Iniciar programa",
            "program": "${workspaceFolder}\\index.js",
            "outFiles": [
                "${workspaceFolder}/dist/**/*.js"
            ]
        }
    ]
}

and in your index.js just run your app:

require('ts-node/register');
require('./src/server');

At the end just press F5 Key in visual studio code and add some breakpoint to start debugging.

you can try this:
"node --inspect -r ts-node/register src/server/main.ts";
.vscode:
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Attach",
"restart": true,
"port": 9229
}
}
