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 🙏

此插件封装原生安卓的输入框组件(EditText),并且禁用了系统软键盘,为的是适用PDA手持项目需求(有硬键盘的安卓手机)。个人原因由于安卓方面不是特别懂,可能会存在一些bug。欢迎各位提issues!

已知问题

由于此组件为原生输入框组件,所以在与react-native-navigation配合使用时候,会发生切换(push)到下一个路由页面但是上一个页面的输入监听还存在的情况,这个是由于react-native-navigation使用的并不是原生的activity来做路由切换,只是类似于一层组件覆盖,所以使用的时候请注意,遇到类似问题可以参考使用以下两种方案解决:
  1. 避免使用push,尽量使用reset
  2. 利用react-native-navigation的全局路由监听和组件方法setEnabled分别控制某个页面上的输入框是否可以输入 如果有更好的解决方案欢迎提PR
