Hops UI Toolbox

 

In this repo, we are experimenting with technology that might serve as our next generation front end technology stack: hops spices our brew (i.e. web front end) with ECMAScript and Flow, CSS Next and CSS Modules, JSX/React and Flux/Redux. To get an impression take a look at our example app.

Hops is not yet another boilerplate. Hops is a self-contained but highly extensible development and build environment that is packaged as a single module. Batteries included.

Install

Besides recent versions of Node.js and npm, hops has no global dependencies. If you need those, we recommend using nvm or similar.

mkdir foo && cd foo
npm init -y
npm install -SE hops

A postinstall script will attempt to bootstrap and configure the project hops is being installed to: after installation, you can instantly start developing.

Run

For developing with hops, you can use any decent editor with up-to-date language support. Those without a favorite we recommend Atom with the linter, linter-eslint and linter-stylelint plugins.

npm start (--production)

If called without the --production flag, a development server with hot module replacement is started. In production mode, a static build is initialized.

API

render(options)

render() is hops main function: it creates a Redux store, sets up React Router and handles rendering both client- and server-side. Using it is mandatory and its output must be the default export of your main module. And it's a little magic.

import { render } from 'hops';

import { reducers } from './reducers';
import { routes } from './routes';

export default render({ routes, reducers });

In addition to routes and reducers, an html mountPoint selector and a createStore factory function may be passed as options.

createAction(key)

createAction() is just a small helper function to work with reducers generated with createReducer().

import { dispatch } from 'store';
import { createAction } from 'hops';

const namespace = 'foo';
const update = createAction(namespace);

dispatch(update({'bar': {'$set': 'baz'}}));

createReducer(key)

createReducer() generates a Redux reducer function using the provided key and React's immutability helpers.

import { createReducer } from 'hops';

const namespace = 'foo';
const reducers = {
  [namespace]: createReducer(namespace)
};

Hops supports server-side data fetching for route components: it calls their static fetchData methods and expects them to return promises. Of course, asynchronous actions are supported by using thunks.
