Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v0.4 以下版本文件請看

輕便、簡單建立、快速擴展

當你想為你的網站添加一些動態渲染、過場特效,但需求又不到檯面上那些功能過於強大的繪圖庫,本庫將是你的好選擇。

<script src="./dist/index.js"></script>
<canvas id="app" width="800" height="600"></canvas>
<script>
    //建立一個實際大小為 1920 * 1080 的畫布
    const app = new LongTake(document.getElementById('app'), 1920, 1080)
</script>

webpack

npm install longtake
import LongTake from 'longtake'
const app = new LongTake(document.getElementById('app'), 1920, 1080)

精靈與精靈樹

Sprite 為該系統的基本單位,每個 Sprite 都封裝了位元圖變形等模式,基本上就是...不要管這麼多了,建立 Sprite 就對了!

const app = new LongTake(document.getElementById('app'), 800, 600)
class Rect extends LongTake.Sprite {
    create() {
        this.resize(50,50)
        this.setAnchor(0.5)
        this.x = app.width / 2
        this.y = app.height / 2
    }
    update() {
        this.rotation += 1
    }
    render() {
        this.fillRect(0, 0, this.width, this.height)
        this.cache()
    }
}
app.addChildren(new Rect())

預載入機制

Loader 將協助您在呈現動畫之前先將圖片載入完成,讓主題圖片不破碎呈現。

let loader = new LongTake.Loader()
loader.add('bear', './img/HighBear.png')
// start為執行載入,你可以在這建立讀取畫面的呈現
loader.start()
// onload為載入完畢執行,你可以隨意使用onload,如果圖片已經載入完成即執行
loader.onload(() => {
    const app = new LongTake(document.getElementById('app'), 800, 600)
    // do something...
})

動畫與緩動函數

Animate 是決定畫面活潑與否的關鍵,本庫內建了30種 緩動函數 為你的動畫添加生命。

class Sprite extends LongTake.Sprite {
    create() {
        this.animate = new LongTake.Animate({
            duration : 1000,
            easing : "easeInQuad",
            action : (t, d)=>{
                // t 為 0 ~ 1
                // d 為 1 ~ 0
            }
        })
    }
    update() {
        this.animate.move()
    }
    render() {
        this.fillRect(0, 0, this.width, this.height)
        this.cache()
    }
}

事件監聽

LongTake 提供了基礎的事件監聽,可以建立簡單的互動模型,但始終是簡易的互動,要複雜的話請慎重考慮。

let sprite = new LongTake.Sprite()
sprite.on('click', () => {
    // do something...
})

Close

如果你要捨棄頁面時,記得關閉正在運行的 LongTake 。

const app = new LongTake(document.getElementById('app'), 800, 600)
// 當你要捨棄頁面...
app.close()
