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 🙏

出码

所谓出码,即将低代码编排出的 schema 进行解析并转换成最终可执行的代码的过程。本模块提供有 Icejs、vue 和 Rax 三套框架的出码方案,并提供了强大而灵活的扩展机制。

使用方法

1) 通过命令行快速体验

欢迎使用命令行工具快速体验:npx @crami/lowcode-code-generator -i example-schema.json -o generated -s vue

--其中 example-schema.json 可以从这里下载

2) 通过设计器插件快速体验

  1. 安装依赖: npm install --save @crami/lowcode-plugin-code-generator
  2. 注册插件:
import { plugins } from '@alilc/lowcode-engine';
import CodeGenPlugin from '@crami/lowcode-plugin-code-generator';

// 在你的初始化函数中:
await plugins.register(CodeGenPlugin);

// 如果您不希望自动加上出码按钮,则可以这样注册
await plugins.register(CodeGenPlugin, { disableCodeGenActionBtn: true });

然后运行你的低代码编辑器项目即可 -- 在设计器的右上角会出现一个“出码”按钮,点击即可在浏览器中出码并预览。

3)服务端出码接入

此代码生成器一开始就是为服务端出码设计的,你可以直接这样来在 node.js 环境中使用:

  1. 安装依赖: npm install --save @crami/lowcode-code-generator
  2. 引入代码生成器:
import CodeGenerator from '@crami/lowcode-code-generator';
  1. 创建项目构建器:
const projectBuilder = CodeGenerator.solutions.vue();
  1. 生成代码
const project = await projectBuilder.generateProject(
  schema, // 编排搭建出来的 schema
);
  1. 将生成的代码写入到磁盘中(也可以生成一个 zip 包)
// 写入磁盘
await CodeGenerator.publishers.disk().publish({
  project, // 上一步生成的 project
  outputPath: '/path/to/your/output/dir', // 输出目录
  projectSlug: 'your-project-slug', // 项目标识
});

// 写入到 zip 包
await CodeGenerator.publishers.zip().publish({
  project, // 上一步生成的 project
  outputPath: '/path/to/your/output/dir', // 输出目录
  projectSlug: 'your-project-slug', // 项目标识 -- 对应生成 your-project-slug.zip 文件
});

注:一般来说在服务端出码可以跟 github/gitlab, CI 和 CD 流程等一起串起来使用,通常用于优化性能。

4)浏览器中出码接入

随着现在电脑性能和浏览器技术的发展,出码其实已经不必非得在服务端做了,借助于 Web Worker 特性,可以在浏览器中进行出码:

  1. 安装依赖: npm install --save @crami/lowcode-code-generator
  2. 引入代码生成器:
import * as CodeGenerator from '@crami/lowcode-code-generator/standalone-loader';
  1. 【可选】提前初始化代码生成器:
// 提前初始化下,这样后面用的时候更快(这个 init 内部会提前准备好创建 worker 的一些资源)
await CodeGenerator.init();
  1. 出码
const result = await CodeGenerator.generateCode({
  solution: 'vue', // 出码方案 (目前内置有 icejs、vue 和 rax )
  schema, // 编排搭建出来的 schema
});

console.log(result); // 出码结果(默认是递归结构描述的,可以传 flattenResult: true 以生成扁平结构的结果)

注:一般来说在浏览器中出码适合做即时预览功能。
