@fit-screen/shared
A fundamental approach to scale-based large-screen adaptive solutions
🌟 Tool
This toolkit provides methods related to assisted computing, as well as a style package through which you can create your own screen adaptive components in any framework.
🦄 Useage
First we download the toolkit
npm install @fit-screen/shared
# or
yarn add @fit-screen/shared
# or
pnpm install @fit-screen/shared
Use this toolkit to develop your own adaptive components.
The following is an example of a FitScreen component developed by Svelte, the component props can be extended by yourself
<script lang="ts">
import { FitScreenEnum, useFitScreen } from '@fit-screen/shared'
import { onMount } from 'svelte'
type FitMode = 'fit' | 'scrollX' | 'scrollY' | 'full'
export let width = 1920
export let height = 1080
export let mode: FitMode = 'fit'
let scaleRef: HTMLDivElement
let entityRef: HTMLDivElement
$: showEntity = mode === FitScreenEnum.SCROLL_X || mode === FitScreenEnum.SCROLL_Y
$: initFitScreenByMode = () => {
const options: Parameters<typeof useFitScreen>[number] = {
width,
height,
mode: mode as FitScreenEnum,
el: scaleRef,
beforeCalculate(scale) {
// If you need X,Y axis scrolling, you need to calculate the entity width and height and add scrolling properties
const dom = entityRef!
dom.style.width = `${width * scale.widthRatio}px`
dom.style.height = `${height * scale.heightRatio}px`
},
}
if (mode === FitScreenEnum.FIT || mode === FitScreenEnum.FULL) {
delete options.beforeCalculate
}
return useFitScreen(options)
}
let isMounted = false
onMount(() => {
isMounted = true
})
let calcRate, resize, unResize
$: if (isMounted) {
// First rendering, and no events registered
// When an update is needed, the event is unregistered and re-registered
if (unResize) unResize()
;({ calcRate, resize, unResize } = initFitScreenByMode())
calcRate()
resize()
}
</script>
<div class={`fit-screen ${mode}`}>
{#if showEntity}
<!-- Entity element, since adaptive scaling is done, require entity dom control in order to calculate scrollbars -->
<div bind:this={entityRef} class="fit-screen-entity">
<!-- Adaptive element -->
<div bind:this={scaleRef} class="fit-screen-scale">
<!-- Display element -->
<div style={`width: ${width}px; height: ${height}px`}>
<!-- Render element -->
<slot />
</div>
</div>
</div>
{:else}
<!-- Adaptive element -->
<div bind:this={scaleRef} class="fit-screen-scale">
<!-- Display element -->
<div style={`width: ${width}px; height: ${height}px`}>
<!-- Render element -->
<slot />
</div>
</div>
{/if}
</div>
<style>
@import '@fit-screen/shared/style.css';
</style>
🚨 Note
Question
Using css files in this way may result in global contamination that.
Solution
Refer to the plugin css and write your own private class.
Use the custom class private prefix helper functions provided by the toolkit, and note that these helper functions need to be available in the node environment.
After you call the classNamePrefix function, the class prefixes you introduce will all be custom, like this.
// vite.config.ts import { defineConfig } from 'vite' import { svelte } from '@sveltejs/vite-plugin-svelte' import { classNamePrefix } from '@fit-screen/shared' classNamePrefix('my-screen_prefix') // https://vitejs.dev/config/ export default defineConfig({ plugins: [svelte()], })
You can call this method from the entry point of your project or from the build configuration. Then
import '@fit-screen/shared/style.css'; function App() { return ( { /** use you custom class prefix */ } <div class={`my-screen_prefix ${mode}`}> <div class="my-screen_prefix-entity"> <div class="my-screen_prefix-scale"> <div style={`width: ${width}px; height: ${height}px`}> <slot /> </div> </div> </div> </div> </div> ) }
🌰 Example
You can check out this svelte base project created by vite
git clone [email protected]:jp-liu/fit-screen.git # or
git clone https://github.com/jp-liu/fit-screen.git
# Then
cd fit-screen
pnpm install
pnpm dev:svelte
