Nanaswiper NPM

Nana's Swiper

You can install it by npm:

npm install --save nanaswiper

you can import it use ES6 import Swiper,{SwiperSlider} from 'nanaswiper'。

Or CommonJS

const Swiper=require('nanaswiper').default
const SwiperSlider=require('nanaswiper').SwiperSlider`

Caution: here CommonJS and ES6 version, I don't add babel-polyfill, so if you need some Feature, you have to babel by yourself.

Major change:

Change how to set slider, less configuration and makes it like react-router's style

It's a slider that only supports horizonal slide. Just for now，I'll develop vertical slide in the next version.

The reason why develop such a swiper,just because a project need sliders with sprit and react. And it's hard to find a 3rd plugin which support for slider,react and canvas. It's easy to find a lot of plugins that support canvas and react or react and slider. That's why I develop such a plugin.

You can check my demo on https://www.cherryvenus.com/slider/

If you want to play with this project, you can clone the repositor and then use following directions to start the project.

build demo

npx webpack --config webpack.config.demo

start a webpack server npm start

This Swiper's config:

params	function	default	required
children	sliders inside swiper is a must	null	yes	sensitive	how sensitive it is when move the swiper to next or prev slider	0.5	no
initMovex	calculator initial slider position	0	no
isLoop	whether loop. One slider or freemode does not support loop	false	no
width	width	window.innerWidth	no
height	height	300	no
isFreeMode	is Free Mode and not support loop mode	false	no
initSliderIndex	inital slider,range from 0 to slider's number minus 1	0	no
slideType	`flatCoverFlow` effect，maybe remove after	""	no

import Swiper,{SwiperSlider} from 'nanaswiper'
<div className="SwiperContainer">
    <Swiper
        initSliderIndex={2}
        sensitive={.2} 
        isLoop={true}
        >
            <SwiperSlider  render={()=>(<div className="defaultSlider">
                slider-ahahah
                </div>)}/>
            <SwiperSlider render={()=>(<div className="defaultSlider">
                slider-gasdffds
                </div>)}/>
            <SwiperSlider render={()=>(<div className="defaultSlider">
                slider-werqwerq
            </div>)}/>
    </Swiper>
</div>

Here follow react-router's style, so you can design your slider by render

<SwiperSlider  render={(props)=>(<div className="defaultSlider">
    slider-ahahah
</div>)}/>

here props params passed to render has following important function:

params	usage
isMoving	whether the swiper is moving,touchmove -1 for left and 1 for right
isActive	whether it's current slider

And if you want an array loop, the following example is for you:

const data=[
    {
        text:"text1"
    },
    {
        text:"text2"
    },
    {
        text:"text3"
    }
]
//...
<Swiper //...>
{data.map((d,index)=>{
    return <SwiperSlider key={`NormalSlider2${index}`} render={()=>(<div className="defaultSlider">
    slider-{d.text}
    </div>)}/>
})}
</Swiper>
//...

Next part is how to use Sprite with Swiper

First, define a sprite template.

import React,{Fragment,Component} from  'react'
import Swiper,{SwiperSlider} from 'nanaswiper'

class SliderSpriteTemplate extends Component{
    render(){
        return (
            <Fragment>
                {this.props.isActive?<Sprite {...this.props}/>:""}
            </Fragment>
        )
    }
}
export {SliderSpriteTemplate}

Next set the sprite's params:

const data=[
    {
        width:window.innerWidth,//sprite width must
        height:300,//sprite height must
        spriteImg:img1,//must
        spriteConf:[3,1,222,350],//sprite'position must
        speed:6,//sprite'speed optional
        tpl:SliderSpriteTemplate//you can set any template you like， it's a must for sprite
    },
    //...
]
export function SpirteSlider(){
   return (<div className="SwiperContainer">
    <Swiper
        sensitive={.2} 
        isLoop={false}
        width={window.innerWidth}
        height={300}>
            {data.map((d,index)=>{
                return <SwiperSlider key={`SpirteSlider${index}`}
                    {/*pass all params to template*/} 
                    render={(props)=><d.tpl {...d} {...props}/>}
                />
            })}
        </Swiper>
    </div>)

Sprite support params:

params	function	default	required
width	canvas'width	""	yes
height	canvas'height	""	yes
data.spriteImg	image to animate	""	yes
data.spriteConf	sprite's config（row num,col num,fpsWidth：width,fpsHeight：height）	{}	yes
data.speed	speed，default 60fps, if set 2 it's 30fps	1	no

Browser version, you can get it from npm run-script broswer, and then dist/nanaSwiper.js is there for you.

How to use? You can directly use it in browser.

        let test=React.createElement(
            Swiper.default,
            {
                sensitive:.2,
                isLoop:true,
                width:window.innerWidth,
                height:300,
            },
            tpl1,

        )
        let div=React.createElement(
            "div",
            {
                className:"SwiperContainer"
            },
            test
        )
        ReactDOM.render(div, document.getElementById('root'));
    </script>

About test, here simulate the touch action, and only test the whether slider is right.
