Cycle-React
An RxJS functional interface
to Facebook's React.
Cycle-React allows users to write React
applications in functional style and represents their UIs as Observables.
In addition, Cycle-React is immutable and uses
PureRenderMixin
internally by default.
Additionally, Cycle-React is also a React-style implementation of a beautiful
framework called Cycle.js.
Installing
npm install cycle-react
Example
let Cycle = require('cycle-react');
let React = require('react');
function computer(interactions) {
return interactions.get('.myinput', 'input')
.map(ev => ev.target.value)
.startWith('')
.map(name =>
<div>
<label>Name:</label>
<input className="myinput" type="text"></input>
<hr />
<h1>Hello {name}</h1>
</div>
);
}
Cycle.applyToDOM('.js-container', computer);
The input of the computer
is interactions
, a collection containing all
possible user interaction events happening on elements on the DOM, which you
can query using interactions.get(selector, eventType)
.
The output of the computer
is Observable<ReactElement>
(a reactive sequence of elements, in other words, view).
Function applyToDOM
subscribes that Observable of elements and renders the
elements to DOM, by using React.createClass
and React.render
internally.
Notice that although React.createClass
is mentioned here, you don't have to
use it. That's why Cycle-React was made. We took functions over classes
and mutable states.
You can learn more about the concept behind applyToDOM
and Cycle
from
André's amazing presentation:
"What if the user was a function?"
Custom element example
let Cycle = require('cycle-react');
let React = require('react');
let Rx = Cycle.Rx;
let Counter = Cycle.component('Counter', function (interactions, props) {
return props.get('counter')
.map(counter => <h3>Seconds Elapsed: {counter}</h3>);
});
let Timer = Cycle.component('Timer', function () {
return Rx.Observable.interval(1000).map(i =>
<Counter counter={i} />
);
});
Cycle.applyToDOM('.js-container', Timer);

Cycle-React is a React-style implementation of Cycle.js, so we have the same
concept of handling user interactions. More information of this concept can be
found at: https://github.com/staltz/cycle
Cycle.js Driver
Starting from
Cycle.js v0.23,
the driver architecture has been introduced.
Cycle-React provides a DOM driver(powered by React, of course) for Cycle.js.
Details can be found at
"Using Cycle-React's DOM driver for Cycle.js".
FAQ
Yes. And no extra configuration needed.
Example
Can I use Cycle-React with other React components and libraries?
Yes. You can even use Cycle-React with your current React apps. Because
component
creates the native React component for you.
Examples for integrating Cycle-React with other libraries are work in progress.
Meanwhile, See
"Working with React"
for guidelines.
Build standalone js
npm run dist
- Ask "how do I...?" questions in Cycle-React's Gitter:
- Propose and discuss significant changes as a GitHub issues
- In addition, more resources can be found at
Cycle.js' page
Disclaimer
Work in progress
Just like Cycle.js, changes to API will occur before 1.0.
0.27.0
Breaking change: Rename "createReactClass" to "component"
For migrating to 0.27, simply replace the string "createReactClass"
to "component".
Fix: Remove unnecessary update on props
change
Add feature: New option "noDOMDispatchEvent" for skipping DOM dispatchEvent
Use "noDOMDispatchEvent" if you want to handle events by using event handlers
completely instead of using interactions.get
API.
