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 🙏

wx-diff

小程序数据路径生成

安装

npm install wx-diff

如何使用

const diff = require("wx-diff");

// 在需要修改数据的地方,使用diff包裹住原来的setData参数
this.setData(diff(before, after));

为什么要生成数据路径

小程序中单次设置的数据大小不能超过 1024KB。

小程序中的 key 可以以数据路径的形式给出,支持改变数组中的某一项或对象的某个属性,如 array[2].message,a.b.c.d。

data 中的值在设置为 undefined 后,这一项将不被设置并可能遗留一些潜在问题。

微信小程序官方文档参考

使用 wx-diff 可有效的解决上述问题,过滤无效参数,生成数据路径。有效提升页面数据更新效率。
