Harmony

Harmony is the engine that drives Bit extensibility and composability.
It's an abstract extension system indended to make any software extendable and composable.

Harmony takes a "micro-kernel" approach and implements the near-minimum amount of software required to build any JavaScript system from independent components through composition.

Installation

``bash
$ bit install @teambit/harmony
`

Quick start

`ts
import { Harmony, Extension } from 'harmony';

@Extensioin
class Person {
sayHello(name = 'world') {
return hello ${name}!;
}
}

const person = Harmony.load(Person);
helloWorld.sayHello(); // returns 'hello world!'
`

Component composition

$3


`ts
class Dude {
constructor(
private person: Person
) {}

sayHello() {
return this.person.sayHello('dude');
}
};

Harmony.load([Dude]).sayHello(); // echos 'hello dude!'
`

$3


`ts
@Extension()
class CLI {
// @hook('command') commands = Hook.create();
static command() {
return Hook.create();
}

run() {
const allCommands = this.commands.list(); // outputs all hook subscribers
}
}

@Extension()
class Compiler {

@command()
main() {
return {
synopsis: 'compile ',
render: () =>
};
}
}
