Reactive-lite

Demo

Web site

Reactive-lite is an opinionated reactive template engine, it works with simple event model which should auto emit change event on value set. the explaination

model-component is a minimal event model, it's a peerDependency of reactive-lite by now.

Features

• Flexible binding fashion, including text-interpolation, attr-interpolation and render function.
• Support reusable binding functions and filter functions for different reactive instances.
• Support config resue between different reactive instances. (makes rendering list components extremely fast, eg: exgrid)
• Support change model on the fly.
• Easily works with checkbox(es) and select element
• Performance concerned, use textContent for text interpolation (use data-html for render html attribute)

Install

npm i reactive-lite

Basic

• interpolation <span>{first} {last}</span>
• filters <span>￥{money | currency}</span>
• render <div data-render="checkActive" >Show on active</div>
• attr-interpolation <a data-href="http://github.com/{uid}">{name}</a>
• event binding <button on-click="onBtnClick">click me</button>
• checked/selected stat <input type="checkbox" name="active" data-checked="active"/>

render functions and event handler functions comes from delegate object.

Usage

var reactive = require('reactive-lite')
var el = document.getElementById('user')
var Model = require('model-component')
var User = Model('User')
  .attr('first')
  .attr('last')
  .attr('age')

var user = new User({first: 'tobi', last: 'john', age: 22})

reactive(el, model)
document.body.appendChild(reactive.el)

API

Reactive(el, model, [option])

• el could be element or html template string
• model contains attributes for binding to the element, and emit change [name] event for reactive
• option is optional object contains config
• option.delegate js object contains event handler and render function(s)
• option.filters js object contains filters functions
• option.bindings js object contains bindings functions
• option.config the config attribute from other reactive instance, supply this option to prevent el(element) parsed twice.

.bind(model)

Bind to a new model, elements would get reacted and event handlers would bind to new model.

.remove()

Unbind all events and remove reactive.el
