A front-end framework for creating modular, configurable and scalable UI components

Synergy provides powerful APIs to help you create configurable modules in Sass, JavaScript and/or React:

Synergy is ideal for creating your presentational React components when using the Container Component Pattern (learn more)

Synergy also povides tools allowing you to combine the above aspects together to create a Synergy Module. Each aspect can work independently and exists as a separate file with a specific role:

These are the core concepts of a UI module.

|-- modules
|   |-- accordion
|   |   |-- accordion.js
|   |   |-- accordion.json
|   |   |-- accordion.jsx
|   |   |-- accordion.scss

Synergy modules can be configured and scaled without having to touch the module's source code

A Synergy module is composed of Components. Both Modules and Components can have Modifiers.

Using Synergy, you can create themes and control your entire project's UI from a single JSON file by passing custom options and parameters to your modules.

Using Synergy to create a basic accordion module which will be configured by accordion.json - Learn more about this example

Fundamental Styles (accordion.scss)

Learn more about module styles

@import '../../node_modules/Synergy/dist/synergy';

@import 'accordion.json';

@mixin accordion($custom: ()) {

    $config: config($accordion, $custom);

    @include module {
        @include component('panel') {
            &:not(:last-child) {
                margin-bottom: this('panel', 'vertical-rhythm');

            @include modifier('active') {
                @include component('toggle') {
                    transform: rotate(90deg);

                @include component('content') {
                    display: block;

        @include component('title', (
            'display': block,
            'cursor': pointer

        @include component('toggle', (
            'float': right

        @include component('content', (
            'display': none

Accordion Interface - JSX (accordion.jsx)

Learn more about module interfaces

import React from 'react';
import { Module, Component } from 'Synergy';

import config from './accordion.json';

export default Accordion = ({ panels, ...props }) => (
    <Module name={config.name} {...props}>
        {panels.map(({title, content}, index) => (
            <Component name="panel" key={index}>
                <Component name="title" onClick={toggle}>
                    <Component name='toggle' /> {title}
                <Component name="content">{content}</Component>

function toggle(event) {
    const panel = event.target.closest('[data-component="panel"]');

    panel.modifier('active', 'toggle');

You could move the toggle interaction (and any other module interactions) into a separate accordion.js file

Accordion Interface - Plain JavaScript (accordion.js)

import { Synergy } from 'Synergy';

import config from './accordion.json';

export default function accordion() {
    Synergy(config.name, accordion => {
        accordion.component('panel', panel => {
            panel.component('title', title => {
                title.addEventListener('click', toggle.bind(panel), false);

function toggle() {
    this.modifier('active', 'toggle');

Accordion Configuration (accordion.json)

Learn more about module configuration

This is where cosmetic (and hence configurable) styles are applied to the module and its components

    "accordion": {
        "name": "accordion",
        "panel": {
            "vertical-rhythm": 0
        "title": {
            "background": "transparent",
            "color": "#444444",
            "border": "1px solid rgba(black, 0.15)",
            "border-radius": 0,
            "padding": "1em",
            "transition": "0.4s",
            "hover": {
                "background": "#2E3882",
                "color": "white",
                "component(toggle)": {
                    "color": "white"
            "active": {
                "background": "#2E3882",
                "color": "white",
                "border-color": "transparent",
                "border-radius": 0,
                "component(toggle)": {
                    "color": "white"
        "content": {
            "background": "white",
            "color": "#444444",
            "border": "1px solid rgba(black, 0.15)",
            "border-radius": 0,
            "padding": "1.5em"
        "toggle": {
            "color": "rgba(black, 0.4)",
            "transition": "0.4s"

Loading Styles (app.scss)

@import '/modules/accordion/accordion';

@include accordion();
With Custom Options
@import '/modules/accordion/accordion';

@include accordion((
    'panel': (
        'vertical-rhythm': 2em
    'title': (
        'background': #06d2ff,
        'color': white

Render Using React (app.jsx)

<div id="demo"></div>
import React from 'react';
import ReactDOM from 'react-dom';

import Accordion from './modules/accordion/accordion.jsx';

    <Accordion panels={[
        {title: 'foo', content: 'bar'},
        {title: 'fizz', content: 'buzz'},
    ]} />, 


Or Initialise Using Plain HTML/JavaScript (app.js)

<div class="accordion">
    <div class="accordion_panel">
        <div class="accordion_title">
            <div class="accordion_toggle"></div> foo
        <div class="accordion_content">bar</div>
    <div class="accordion_panel">
        <div class="accordion_title">
            <div class="accordion_toggle"></div> fizz
        <div class="accordion_content">buzz</div>
import accordion from './modules/accordion/accordion.js';
