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 🙏

使用 JavaScript Proxy 特性对微信小程序的 `wx` 进行封装,使之以返回 `Promise` 对象的形式进行调用。随后可以使用 `await` 关键字简化程序结构。

awx = asynchronous wx

使用 JavaScript Proxy 特性对微信小程序的 wx 进行封装,使之以返回 Promise 对象的形式进行调用。随后可以使用 await 关键字简化程序结构。

一、安装和引用

直接使用源文件

找到 dist/awx.esm.js,拷贝到小程序项目目录(假设是 /util/awx.esm.js),在 app.js 中作为本地源文件引用:

import { asyncProxy } from "./util/awx.esm";

npm 安装

需要参考 微信开发文档的 npm 支持

npm install @jamesfancy/awx

引用

import { asyncProxy } from "@jamesfancy/awx";

二、注入 app

由于 asyncProxy 每次调用都会封装新的代码对象,而 asyncProxy 封装出来的代理对象只会缓存使用到的函数(懒加载)。建议在程序启动时使用 asyncProxy 封装 awx,注入 app 对象中。

// app.js
import { asyncProxy } from "./util/awx.esm";
// 或
// import { asyncProxy } from "./utils/async";


App({
    onLaunch: function () {
        this.awx = asyncProxy(wx);
        // ...
    }
});

三、在程序中使用

const app = getApp();
const { awx } = app;

Page({
    someMethod() {
        awx.request(...);
    }
});
