nativescript-emulator-reload

This small gulp script will monitor the source files of a NativeScript project and when a file is changed it'll rebuild and reload the emulator. Will also use Babel to compile your ES6+ JS into ES5 if you want it to.

Currently only supports iOS emulators.

Install

Either download from Github:

Download the package.json and gulpfile.js and put in the root directory of your app. Then run

npm install

Or install from NPM:

cd /your/project/root
npm install nativescript-emulator-reload
mv node_modules/nativescript-emulator-reload/* .
rm -rf node_modules/nativescript-emulator-reload
npm install

Run

gulp

or with a device flag:

gulp -d iPad-Retina

ECMAScript 6 version.

If you want to use ECMAScript 6 there's an gulpfile (gulpfile.es6.js) which will use Babel to turn your ES6+ code into ES5 code.

To use this file, rename gulpfile.js to gulpfile.es5.js (or really to anything) and rename gulpfile.es6.js to gulpfile.js.

gulp watch

The ES6 Gulpscript is opinionated

You most probably need to edit the settings in the gulpfile.

The default settings assumes the following file structure:

/app
    /src
        /shared
        /test
        /views	
    /tns_modules
    /App_Resources
    /...			

Where the content of src will be moved to /app when compiled. Creating a file structure like:

/app
    /src
        /shared
        /test
        /views	
    /tns_modules
    /App_Resources
    /...
    /shared
    /test
    /views		

Where the app/{shared,test,views} are the compiled version of app/src/{shared,test,views}. This way only the ES6 files will be compiled (and not things like tns_modules, anything in node_modules if you install npm packages, etc.)

Testing with Mocha

Mocha is included for your testing pleasures.

Place your tests in /src/test and run them with gulp test

Linting with eslint

eslint is included for your linting pleasures.

Lint the code in your app/src folder by running gulp lint.

If you're using ES6 you most probably want these settings in your .eslintrc in the root directory of your project. es6: true will enable all ES6 features but modules which is enabled by "ecmaFeatures": { modules: true }. Read more about configuring eslint.
