Stencil: Add Source-Maps

[mmakrzem]

Stencil version:

 @stencil/[email protected]

I'm submitting a:

[] bug report
[X] feature request
[ ] support request => Please do not submit support requests here, use one of these channels: https://stencil-worldwide.herokuapp.com/ or https://forum.ionicframework.com/

Current behavior:
I'm using the stencil starter project found here (https://github.com/ionic-team/stencil-component-starter) and I would like to debug the code in visual studio code. The following configuration lets me launch chrome from within visual studio code:

"configurations": [
 {
  "type": "chrome",
  "request": "launch",
  "name": "Launch Chrome against localhost",
  "url": "http://localhost:3333",
  "sourceMaps": true,
  "webRoot": "${workspaceFolder}/www"
 }
]

Expected behavior:
When I place a breakpoint in visual studio code, I expect execution to stop there. This doesn't happen. Instead I get a warning saying 'unverified breakpoint' for all the breakpoints I place in the code.

I have the same problem

See my answer on StackOverflow, specifically the part about source maps:

But since Stencil does not generate source maps yet you will only be able to debug the compiled code.
Source: https://github.com/ionic-team/stencil/issues/219

My method for finding the correct generated file is to just add a debugger; statement so that VS Code will automatically break.

any update on this? is it maybe also possible to debug unit tests / e2e tests?
edit: after playing around with some settings, i found out how to debug tests. It even maps the ts code correctly. Here is my configuration:

{
    "type": "node",
    "request": "launch",
    "name": "Test",
    "program": "${workspaceFolder}/node_modules/@stencil/core/bin/stencil",
    "args": [
        "test",
        "--spec",
        "--e2e",
        "--runInBand"
    ],
    "console": "integratedTerminal",
    "internalConsoleOptions": "neverOpen",
    "disableOptimisticBPs": true
}

Sourcemaps are something we plan to add to the roadmap. I will leave this issue open as the reference for implementing them.
