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 🙏

Vite plugin to load .pag files as ArrayBuffer for Mini Program, UniApp, and H5

Readme

vite-plugin-pag-loader

一个在不同环境中无缝将 .pag 文件作为 ArrayBuffer 加载的 Vite 插件。 它通过自动检测环境来解码 Base64 字符串,支持微信小程序、UniApp 和 H5 浏览器。

安装

npm install vite-plugin-pag-loader -D
# 或
yarn add vite-plugin-pag-loader -D
# 或
pnpm add vite-plugin-pag-loader -D

使用

在你的 vite.config.tsvite.config.js 中:

import { defineConfig } from 'vite';
import pagBufferPlugin from 'vite-plugin-pag-loader';

export default defineConfig({
  plugins: [
    pagBufferPlugin()
  ]
});

然后你可以在代码中直接导入 .pag 文件,它们将被解析为 ArrayBuffer

import myPagFile from './assets/animation.pag';

console.log(myPagFile); // 它将是一个 ArrayBuffer!

// 配合 pag 库使用
// const pagFile = await PAG.PAGFile.load(myPagFile);

TypeScript 声明

为了在导入 .pag 文件时获得 TypeScript 的类型支持,你可以添加一个声明文件(例如 src/vite-env.d.tssrc/pag.d.ts):

declare module '*.pag' {
  const content: ArrayBuffer;
  export default content;
}

工作原理

该插件在构建时将 .pag 文件转换为 Base64 字符串,并返回 JavaScript 代码以便在运行时将其转换回 ArrayBuffer。 它支持环境检测:

  1. 微信小程序使用 wx.base64ToArrayBuffer
  2. UniApp(支付宝、抖音等)使用 uni.base64ToArrayBuffer
  3. 标准 H5 浏览器使用 window.atob
