Ionic-app-scripts: Revisit Source Maps

[danbucholtz]

• [x] Not all of ionic-angular has a source map

• [x] Investigate cheaper source map options with original source

• [x] Improve docs and show an example

Hi @danbucholtz

Is there a solution yet to get source-maps working on Windows ?
This is seriously affecting our enterprise app development as our Ionic 2 development environment is on Windows 7 Enterprise.
Is there a solution yet to get source-maps working on Windows ?

@rajpat,

Yes, it should work in 0.0.47.

Thanks,
Dan

Have you guys got source maps working, finally?
I just downloaded the latest "ionic2-app-base", with the npm modules installed:

Still no source maps in Safari (running the app in ios Simulator).
What am I missing?

Thanks!

I started a new project yesterday (RC4) and source maps are now working, at
least using Chrome with either Ionic serve or the browser emulator (i.e.
debugging from VS Code) on Windows

My components are exactly the same version as yours....

"@angular/common": "2.2.1",
"@angular/compiler": "2.2.1",
"@angular/compiler-cli": "2.2.1",
"@angular/core": "2.2.1",
"@angular/forms": "2.2.1",
"@angular/http": "2.2.1",
"@angular/platform-browser": "2.2.1",
"@angular/platform-browser-dynamic": "2.2.1",
"@angular/platform-server": "2.2.1",
"@ionic/storage": "1.1.6",
"ionic-angular": "2.0.0-rc.4",
"ionic-native": "2.2.11",
"ionicons": "3.0.0",
"rxjs": "5.0.0-beta.12",
"zone.js": "0.6.26"
},
"devDependencies": {
"@ionic/app-scripts": "0.0.47",
"typescript": "2.0.9"
},

Apologies, should have been clearer about the issue.

The source map is generated (main.js.map) in the build/ folder, but apparently not loaded / considered by Safari. I also can't judge whether the created map is legit.

I do see statements in the main.js file:
//# sourceMappingURL=index.js.map

I may know enough about how source maps are loaded and correlated but it strikes me that one JS file can have multiple individual source map directives that essentially point to non existent files.

_EDIT:_
tried adding this: "ionic_source_map_type": "eval"
and voila the *.ts counterparts started to appear in Safari.

_EDIT2:_
could have been the reloading within Safari as well, which interestingly enough kills the emulator/app 2 out of 3 times...jeez.

I've tried everything I can think of and everything I've found here to get source maps working in safari with ionic 3. Should this just work out of the box at this point? Debugging on iOS is very frustrating for me a present.
