# gulp-transform-interface

A plugin for gulp that will compile Java-style interfaces to Javascript.

## Installation

```
$ npm install gulp-transform-interface --save-dev
```

## Use case

This plugin will extend the Javascript language with interface declarations like you know them from Java.

Here's the syntax you can now use:

```javascript
interface FooBar {
    isFoo = Boolean;
    barCollection = Map;
    sayFoo(arg1, arg2);
    doBar();
}
```

This compiles down to the following ES2015 code:
```javascript
const FooBar = {
    isFoo: Boolean,
    barCollection: Map,
    sayFoo(arg1, arg2){},
    doBar(){}
}
```

Combining this with the npm package `gulp-class-implements-polymerjs` gives the possibility for declaratively implementing interfaces by
supporting the Java-inspired `class <subclass> extends <class> implements <interface>` syntax.

interfaces are NOT part of the official ES2015 module spec. Be aware that the syntax this plugin expects isn't and probably never will be officially supported.

## Usage

Simply add it to your `gulpfile.js`:

```javascript
const INTERFACE_EXTENSION = require('gulp-transform-interface');

    gulp.src("./components/**/*.*")
        .pipe(INTERFACE_EXTENSION())
        .pipe(gulp.dest(COMPILED_DIRECTORY + "/components"));
```
