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 🙏

宿主配置文档契约:host-config 服务描述符与配置文档类型(AalisConfig,供各域 declaration merging)

Readme

@aalis/api-host-config

宿主配置文档契约:host-config 服务描述符、HostConfig 读写面与配置文档类型 AalisConfig。不含服务实现。

角色

  • hostConfig:服务描述符。Node 宿主 @aalis/runtime 把配置文档(aalis.config.yaml)以它独占登记在根上;别的宿主要让插件读写文档,自己提供。管理类插件(WebUI、市场、CLI、authority)在 uses 里声明它。
  • HostConfig:文档读写面加 save()。写方法只改文档;管理动作只改运行态。要跨重启保留,调用方两边都写。
  • AalisConfig:配置文档类型,也是各域业务字段做 declaration merging 的目标。
  • ConfigSaveRefusedError / isConfigSaveRefused(err):配置源有尚未生效的外部修改、宿主为免覆盖而拒写时 save() 的拒绝原因,以及用来把它与写入失败区分的判据。判据按错误的 name 判定,进程里装有两份本包时也认得。

安装

pnpm add @aalis/api-host-config

使用

import { optional } from '@aalis/core';
import { hostConfig } from '@aalis/api-host-config';

// uses: { plugins: pluginsService, doc: optional(hostConfig) }
if (await plugins.require().disable(id)) {
  const store = doc.current;
  if (store) {
    store.setPluginEnabled(id, false);
    await store.save();
  }
}

扩展文档字段:

declare module '@aalis/api-host-config' {
  interface AalisConfig {
    myFeature?: { enabled: boolean };
  }
}
