Getting Started

Installation

Install ember-command with:

ember install ember-command

Usage

The idea for ember-command is clearly to separate your business logic from your UI by offering a couple of mechanics to do that.

Actions

Write an action that invokes a service within a single file component.

import { action } from 'ember-command';
import { on } from '@ember/modifier';

const inc = action(({ services }) => () => {
  services.counter.inc();
});

const Counter = <template>
  <button type="button" {{(inc)}}>+</button>
</template>

export default Counter;

Composing

Compose various commands together to form a primitive that can be passed around. This works well in combination with ember-link.

Let's make a link and add tracking to it:

import { command, action, CommandElement } from 'ember-command';
import { link } from 'ember-link';

const track = action(({ services }) => (event: string) => {
  services.tracking.track(event);
});

const HomeLink = <template>
  <CommandElement @command={{command 
    (fn (track) "go home")
    (link "application")
  }}>Home</CommandElement>
</template>

export default HomeLink;
