advanced seed for community in progress - request for assistance

[NathanWalker]

I am working on a relatively advanced angular2-seed which will feature {N} integration:
https://github.com/NathanWalker/angular2-seed-advanced

I'm running into an issue. Curious if someone could be so kind to take a look by following the instructions here to get setup and trying to help:
https://github.com/NathanWalker/angular2-seed-advanced/blob/development/NATIVESCRIPT_SUPPORT.md

[hdeshev]

JS ERROR ReferenceError: Can't find variable: __metadata

You get this one if you don't have reflect-metadata imported, or your compiler isn't emitting helpers or decorator metadata.

Out of curiosity, why do users need to edit tns-core-modules.d.ts? What is the original issue, and can we do anything about it?

[NathanWalker]

tns-core-modules.d.ts includes references to:

/// <reference path="declarations.d.ts" />
/// <reference path="es-collections.d.ts" />
/// <reference path="es6-promise.d.ts" />
/// <reference path="es6.d.ts" />
/// <reference path="weakmap.d.ts" />

Those cause problems when paired with other build setups that already include those typings.
We should probably get NativeScript typings on the typings registry here since tsd is deprecated.
Instead of including those global typings in tns-core-modules.d.ts, it could be instructed for end user's to setup their typings.json to contain the typings that are needed.
This way tns-core-modules.d.ts would only cover typings for NativeScript libraries.

I am importing reflect-metadata here:
https://github.com/NathanWalker/angular2-seed-advanced/blob/development/src/app/app.ts
Maybe it needs to be imported in other files as well?
Maybe something incorrect here:
https://github.com/NathanWalker/angular2-seed-advanced/blob/development/src/tsconfig.json

Thank you for your help @hdeshev

[NathanWalker]

I was able to get past it by removing this option in tsconfig.json:

"noEmitHelpers": true

👍 It's close to working now... just a few things left to work with Http and ng2-translate

[NathanWalker]

Ok @hdeshev I've gotten much further with your help (thank you!) and I updated the {N} instructions here:
https://github.com/NathanWalker/angular2-seed-advanced/blob/development/NATIVESCRIPT_SUPPORT.md

But I am now running into this:

CONSOLE ERROR file:///app/tns_modules/angular2/src/platform/server/parse5_adapter.js:53:75: ORIGINAL EXCEPTION: TypeError: this.http.get(this.sfLoaderParams.prefix + "/" + lang + this.sfLoaderParams.suffix)
                .map is not a function. (In 'this.http.get(this.sfLoaderParams.prefix + "/" + lang + this.sfLoaderParams.suffix)
                .map(function (res) { return res.json(); })', 'this.http.get(this.sfLoaderParams.prefix + "/" + lang + this.sfLoaderParams.suffix)
                .map' is undefined)

This is coming from the internals of ng2-translate (https://github.com/ocombe/ng2-translate/blob/master/src/translate.service.ts#L40-L41).

I have of course imported the .map operator here:
https://github.com/NathanWalker/angular2-seed-advanced/blob/development/src/app/app.ts#L12

I have also seen your Http sample here:
https://github.com/NativeScript/sample-ng-http

But I don't see anything I'm missing. Any idea what this last error is and why it's not importing the .map operator correctly?

Apparently this same question was asked on stackoverflow a couple weeks ago with no answer:
http://stackoverflow.com/questions/34899835/using-map-in-nativescript-with-angular2

I am experiencing the same trouble.

Hey @NathanWalker,

The issue looks like this one #38 which has already been fixed in the iOS runtime. You can try downloading the latest iOS runtime bits from here and use them. As those builds are not verified I'm not sure what will be their stability.

[NathanWalker]

@ligaz Thank you! I will try this! ..crossing fingers..

[NathanWalker]

Hmm unfortunately I now get this error setting up all the latest nightly's as that nativescript.rocks site mentions:

ld: warning: directory not found for option '-F/Users/nathan/Documents/github/NathanWalker/angular2-seed-advanced/src/platforms/ios/../../lib/iOS'
ld: can't open -sectcreate file: /Users/nathan/Documents/github/NathanWalker/angular2-seed-advanced/src/platforms/ios/build/emulator/metadata-i386.bin
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The typings problem is related to NativeScript/NativeScript#1457. I started working on it today, and it will probably land in master tomorrow. The idea is for Angular apps to reference a different dts file for the nativescript components. I'm not sure tns-core-modules.es6.d.ts will suffice yet -- I may have to come up with another :-/

Anyway, solving this problem would get rid of the ugly build hook that regex-replaces stuff in the angular d.ts files to delete certain references that cause compile-time type conflicts.

[NathanWalker]

Ok that makes sense. Thank you for this insight and let me know if I can help in anyway to move that forward. Give me a task, seriously. I'm quite anxious to get this working :)

@ligaz - The builds on NativeScript.rocks are straight from source every afternoon my time. (The majority of the NS core team is deeply sleeping midday my time; so it is the safest time to make sure I capture everyone's work on master for the day).

The actual status:

1. Android runtimes have my liveedit & encryption patches automatically applied.
2. iOS runtimes, no patches yet -- but eventually will have the same patches as above.
3. TNS Core Master - totally unchanged, just TS -> JS'd.

These are all build from Master, including the required sub-projects (widgets, metadata, v8).
v8 is only built when a new v8 is setup in master; as their is no point rebuilding the same code everyday --- so right now my android masters are actually running on the new 4.7.80. 😀

I do occasionally have to kick the android build as occasionally the NS team breaks my patches by adding new code around one of the diff locations and diff's won't apply cleanly, but otherwise it is a totally automated process; so if it doesn't work; it is because the master is broken. 😀
