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 🙏

Readme

@alitajs/keep-alive

安装

yarn add @alitajs/keep-alive
or
npm i @alitajs/keep-alive

启用方式

配置keepalive:[]开启。

介绍

暂时的 keep alive 实现,有点投机。我们有多个项目用于生产环境中。你需要自行评估风险。采用的方案,是在 layout 自己维护一份组件的显示或者隐藏,通过控制 key 变化,来实现的。等 Umi 官方的 keep alive 推出,我们会在底层采用 Umi 的方案,而保持以下的 api 不变,这意味着,你可以无感优化。

需要使用组件包裹 layout 的最内层。原理就是劫持了 children

配置

比如:

export default {
  plugins: ['@alitajs/keep-alive'],
  keepalive: ['/pathname'],
};

使用

// src/layouts/index.tsx
import { KeepAliveLayout } from 'umi';
const BasicLayout: React.FC = (props) => {
  return (
    <OtherLayout>
      <KeepAliveLayout {...props}>{children}</KeepAliveLayout>
    </OtherLayout>
  );
};

umi 接口

常用方法可从 umi 直接 import。

比如:

import { dropByCacheKey, patchKeepAlive } from 'umi';

接口包含

dropByCacheKey

解除状态保持

// src/pages/list/index.tsx
import { dropByCacheKey } from 'umi';
const Page: React.FC = (props) => {
  return (
    <div
      onClick={() => {
        dropByCacheKey('/list');
      }}
    >
      Click dropByCacheKey
    </div>
  );
};

patchKeepAlive

动态修改 keepalive 配置

// 假如 config 中配置 keepalive: []
import { patchKeepAlive } from 'umi';
const Page: React.FC = (props) => {
  return (
    <div
      onClick={() => {
        //
        patchKeepAlive((config) => {
          // 这里可以获取到最新的 keepalive 配置
          config.push('/list');
          // 操作配置之后返回
          return config;
        });
      }}
    >
      Click patchKeepAlive
    </div>
  );
};
