Support for TypeScript-based NativeScript projects

[tailsu]

As a NativeScript used, I want to develop my project in TypeScript, but I don't want to muck around with TypeScript compilers, Grunt, Gulp or whatever.

How to Use

Execute:

$ tns install typescript

From now on, commands like tns prepare, tns build, etc. will compile all *.ts files under app/ and output the respective *.js files and the compiled files will be the ones that go into the built package.

Implemented in #1116

The transpilation does not work when outside the project the prepare command is executed through the --path option. For example: tns prepare android/io --path <absolute/relative path>.

@vchimev the issue is fixed in version 0.2.1 of nativescript-dev-typescript module. Can you test again :)

[vchimev]

It's fine, thanks.

@tailsu, @rosen-vladimirov - Is there any way to preserve my own .tsconfig as currently it is overwritten every time when tns install typescript is called?

[rosen-vladimirov]

Hm, what's the use-case to call it more than once?

[vchimev]

I'm concerned about the scenario when I have already my .ts project along with .tsconfig file, than executing tns install typescript will overwrite my .tsconfig.

However, for the release of {N} CLI version 1.5 and nativescript-dev-typescript version 0.2.1 the scenario above will not be supported.

How you could get started - install NativeScript CLI version 1.5 when it is released

npm install -g nativescript

• clone NativeScript Hello World project template for TypeScript:

git clone [email protected]:NativeScript/template-hello-world-ts.git template-hello-world-ts

• create a new app using the template:

tns create myApp --copy-from template-hello-world-ts

• change the current working directory to your new app

cd myApp

• install the TypeScript module

tns install typescript

Than executing any of the commands: tns prepare, tns build, tns run will compile all *.ts files under app/ directory and output the respective *.js files; the compiled files will be the ones that go into the built package.
