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 🙏

ZenWeb ORM module

ZenWeb ZenORM

ZenORM Repositories 集成

安装

npm install @zenweb/mysql @zenweb/orm
npm install @zenorm/generate @zenorm/generate-mysql --save-dev

配置

package.jsonscripts 中增加如下代码,用于执行 dbgen 命令

{
  "scripts": {
    "dbgen": "zenorm-generate .dbgen.json"
  }
}

创建文件 .dbgen.json 用于生成数据库结构代码时连接到指定数据库

提示:运行时并不使用此配置

{
  "host": "localhost",
  "port": 3306,
  "user": "root",
  "password": "",
  "database": "zenorm_test",
  "outputDir": "./model",
  "generateRepositories": true,
  "declareRepositoriesToModules": [
    "@zenweb/core.Core.repositories"
  ]
}

生成数据库结构代码

运行命令开始生成数据库结构代码

npm run dbgen

项目配置

编辑项目入口代码 src/index.ts

import { create } from 'zenweb';
import modMySQL from '@zenweb/mysql';
import modORM from '@zenweb/orm';
import { Repositories } from './model';

export const app = create();

// 安装 MySQL 支持
app.setup(modMySQL({
  pools: {
    // 这里的数据库配置用于运行时
    MASTER: {
      host: 'localhost',
      port: 3306,
      user: 'root',
      password: '',
      database: 'test',
      charset: 'utf8mb4',
      timezone: '+08:00',
    },
    // 如果使用集群,主从分离等场景可以继续添加
    // SLAVE1: {} ...
  }
}));

// 设置 ORM
app.setup(modORM({
  coreQuery: () => app.mysql!,
  // contextQuery: (ctx) => app.mysql,
  Repositories,
}));

代码中调用

import { mapping } from 'zenweb';

export class TestController {
  @mappping()
  dbtest(core: Core) {
    const { UserRepository } = core.repositories;
    return UserRepository.find({ id: 1 }).get();
  }
}
