Setting up your Angular2-Typescript application to run smoothly in VS Code

I'm feeling quite lost here, could someone please help me make sense of this configuration?

launch.json 
"configurations": [
        {
            "name": "Launch",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/workspace/angular/app/main.ts",

I've noticed various options for the "program" attribute but I'm unsure of its purpose.

The only setup that seems to work for me is:

"program": "${workspaceRoot}/workspace/angular/node_modules/lite-server/bin/lite-server",

However, this setup doesn't allow me to debug the application and opens the browser at "http://localhost:3000", which isn't the full app address.

I've seen examples like:

"program": "${workspaceRoot}/app/app.js",
"program": "${workspaceRoot}/app/app.ts",

But none of them seem to run; I keep encountering "System is not defined" errors. What should main.ts contain?

I've also come across this variation:

"program": "http://localhost/blabla/index.html",

What is the correct approach in this case?

Answer №1

Have you experimented with the Chrome debugger extension in vscode?

  1. Ensure that source maps are enabled
  2. Include these setups in your launch.json

{
    "version": "0.1.0",
    "configurations": [
        {
            "name": "Attach with sourcemaps",
            "type": "chrome",
            "request": "attach",
            "port": 9222,
            "sourceMaps": true,
            "url": "<url of the open browser tab, you wanna connect to"
        },
        {
            "name": "Attach to url with files served from ./out",
            "type": "chrome",
            "request": "attach",
            "port": 9222,
            "url": "<url of the open browser tab, you wanna connect to",
            "webRoot": "${workspaceRoot}/out"
        }
    ]
}

  1. Initiate Chrome with remote debugging enabled, 
    chrome --remote-debugging-port=9222
