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 🙏

多文件编辑器

借助此插件可在低码引擎上使用任意层级的文件树进行代码的组织

Demo

import multipleFileCodeEditorFactory from '@alilc/lowcode-plugin-multiple-editor';

import { PrettierPlugin } from '@alilc/lowcode-plugin-multiple-editor/es/plugins/prettier-plugin';


const PLUGIN_NAME = 'multiple-file-code-editor';
// 详细参数可见 ts 类型声明
const plugin: any = multipleFileCodeEditorFactory({
  softSave: true, // true 保存代码时将代码保存在插件类上,并不会调用引擎的 importSchema
  es6: true, // 编译选项,true 时仅做 es module 的编译
  // 可选择使用插进进行代码编辑器功能的拓展
  plugins: [searchPlugin as any, lintPlugin, new PrettierPlugin()],
  // 内置钩子,在插件初始化时进行一些操作,例如添加类型声明
  onInstall(controller: EditorController) {
    for (const [path, content] of extraLibList) {
      controller.addExtraLib(content, path);
    }
    controller.addComponentDeclarations(declarations);
    controller.onImportSchema(async (schema) => {
      // Todo sth.
    });
    window.codeEditorController = controller;
  },
  defaultFiles: {
    utils: `
export function helloWorld() {
  console.log('hello world');
}
    `
  }
});

plugin.pluginName = PLUGIN_NAME;

await plugins.register(plugin);

工作原理

使用该插件时,每次保存时:

  1. 编译代码,生成 __initExtra 函数方法,该方法用于初始化各个方法、生命周期的真实定义
  2. 修改 constructor 函数体,函数体内执行 __initExtra,constructor 将会在渲染引擎内执行,执行完成后即可得到所有方法和生命周期的真实定义
  3. 在 schema 上保存一个文件 Map,保存位置为 schema.componentsTree[0]._sourceCodeMap

使用注意事项

  1. 建议所有 project.importSchema 和 project.exportSchema 替换为 codeEditorController.importSchema 和 codeEditorController.exportSchema。原因是插件内部需要对文件内容进行处理
  2. 不能在 index.js 的 Class 之外进行函数、变量定义,如需定义则在其他文件内定义
  3. 不能在 index.js Class 的 state 定义中使用表达式
  4. 如需在 setter 内适用类型定义,请开启 base-editor 的单例模式,仅需在应用入口处调用如下方法即可:
  5. 如果低码项目有使用出码,则需对出码进行定制,将 _sourceCodeMap 中的文件生成到项目中,并对文件的引用进行处理,具体处理方式可自行组织

使用单例模式

import { configure } from '@alilc/lowcode-plugin-base-monaco-editor';
configure({ singleton: true });
