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 🙏

FAQ

1. 为什么微信里面通过分享卡片能唤起,直接打开链接却无法唤起的?

截止 2023-08-10,只有微信 SDK 生成的卡片和服务号推送的消息才能唤起 App。

2. 如何修改按钮样式?

方法一(推荐):

如官方所说,模版的样式是和页面隔离的,建议将此处透明的开放标签覆盖在原按钮上,这样就可以保留原按钮的样式,同时又可以实现点击跳转。

方法二:

通过 launchBtnStyle 参数添加内联样式,通过 launchBtnText 参数修改按钮文字。

3. 如何确保满足唤起的所有前置条件?

(1)开放平台、服务号已认证,并且主体一致;

(2)开放平台绑定服务号;

(3)开放平台绑定移动应用,并且已认证;

(4)服务号绑定域名。
