ember-cli-jss

JSS integration for Ember

Install

$ npm install --save ember-cli-jss

Usage

The property stylesheet must be an instance of the StyleSheet.

Properties jssNames and jssNameBindings work like classNames and classNameBindings, respectively.

When you update properties listed in the jssObservedProps, dynamic styles will be updated.

// ...awesome-component/component.js

import Component from '@ember/component';
import JSS, { TaglessJSS } from 'ember-cli-jss';
import stylesheet from './stylesheet';

export default Component.extend(JSS, {
  stylesheet,
  jssNames: ['wrapper'],
  jssNameBindings: ['isShow:show'],
  jssObservedProps: ['color'],

  color: 'blue',
  isShow: true,

  actions: {
    changeColor(color) {
      this.set('color', color);
    },
  },
});

// For tag-less component use TaglessJSS
export default Component.extend(TaglessJSS, {
  stylesheet,
  jssObservedProps: ['color'],
  tagName: '',
  color: 'blue',

  actions: {
    changeColor(color) {
      this.set('color', color);
    },
  },
});

Constructor StyleSheet accepts the same arguments as jss.createStyleSheet.

// ...awesome-component/stylesheet.js

import { StyleSheet } from 'ember-cli-jss';

export default new StyleSheet({
  wrapper: {
    width: 600,
    display: 'none',
  },

  show: {
    display: 'block',
  },

  content: {
    color: (data) => data.color,
  },
});

{{!-- ...awesome-component/template.hbs --}}

<button type="button" {{action "changeColor" "green"}}>
  Green
</button>

<div class="{{jss 'content'}}">
  Lorem ipsum...
</div>

Helper

<button class="{{jss 'large' 'primary' disabled=true}}">
  Submit
</button>

Configuration

Plugin jss-preset-default applied by default. Please note that the work of the dynamic properties depends on jss-compose plugin.

You can override the app/initializers/ember-cli-jss.js.

// ...app/initializers/ember-cli-jss.js

import jss from 'jss';
import preset from 'jss-preset-default';

export function initialize() {
  jss.setup(preset());
}

export default {
  name: 'ember-cli-jss',
  initialize,
};
