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 🙏

项目结构(必须)

ROOT: {
    config(s): "配置文件Config存放处",
    plugin(s): "插件统一存放, 只加载根目录的文件及文件夹, 不支持文件包含",
    helper(s): "工具辅助类统一存放(一般是固定不变的静态工具)",
    middleware(s): "中间件统一存放",
    controller(s): "控制器统一存放",
    service(s): "服务类型统一存放",
    router(s): "路由控制类统一存放",
}

类加载顺序: config > plugin > helper > middleware > controller > service > router

Init

初始化, 例如:

    const AppCore = require('./app/server');

    const app = new AppCore({
        baseDir: __dirname, // 根目录, (选配, 默认 process.cwd())
    });

Config

环境配置: .env , 如下:

    HOSTNAME=localhost
    # node env
    NODE_ENV=development
    # scope
    SERVER_SCOPE=local

    # logger 启用日志列表
    LOGGER_ALLOW=*  # 全部开启
    LOGGER_ALLOW=DEBUG,INFO,ERROR,WARN  # 部分开启
    # logger 禁用日志列表
    LOGGER_BAN=NULL # 不开启禁用
    LOGGER_BAN=* # 全部禁用
    LOGGER_BAN=TEST,SYSTEM # 部分禁用

    CORE_NAME=2O3T-Core # 应用名称

配置文件支持类型 [ js | json ]

加载顺序:

Will merge config(s)/default.js 和 config(s)/${process.env.SERVER_SCOPE}.js 和 config(s)/${process.env.NODE_ENV}.js 和 config(s)/${process.env.SERVER_SCOPE}_${process.env.NODE_ENV}.js

    '/configs/default.js',
    '/configs/local.js',
    '/configs/development.js',
    '/configs/local_development.js',

    '/configs/plugin.default.js',
    '/configs/plugin.${scope}.js',
    '/configs/plugin.${env}.js',
    '/configs/plugin.${scope}_${env}.js',

    '/configs/middlewares.default.js',
    '/configs/middlewares.${scope}.js',
    '/configs/middlewares.${env}.js',
    '/configs/middlewares.${scope}_${env}.js',

    '/configs/controller.default.js',
    '/configs/controller.${scope}.js',
    '/configs/controller.${env}.js',
    '/configs/controller.${scope}_${env}.js',

    '/configs/service.default.js',
    '/configs/service.${scope}.js',
    '/configs/service.${env}.js',
    '/configs/service.${scope}_${env}.js',

    '/configs/router.default.js',
    '/configs/router.${scope}.js',
    '/configs/router.${env}.js',
    '/configs/router.${scope}_${env}.js',

优先级:

    default > {SERVER_SCOPE}  > {NODE_ENV} > {SERVER_SCOPE}_{NODE_ENV}

Plugin

插件代表是组件, 可独立生产(但是不能独立运行),插件中的 中间件 会进行全局注册, 并且优先级最高。 默认自动加载plugin(s)目录下文件, 可在初始化时, 更改目录路径.

PluginConfig

可配置config信息, 如下:

// 普通配置
module.exports = {
    mixins: [ 'plugin1', 'plugin2' ],  // 指定加载顺序, 自动加载plugin(s)目录下文件
    plugin1: { // 给 ‘plugin1’ 指定配置文件
        s: [],
    },
};
// 文件夹 或 模块配置
module.exports = {
    middleware: { // 扩展中间件
        mixins: [ 'a-b', 'c-0', 'bodyParse' ], // 全局顺序注册加载
        bodyParse: {
            enable: true, // 开启全局注册(可选)
            p: "", // 参数
        },
    },
    controller: { // 扩展 controller
        mixins: [ 'user' ],
    },
    service: { // 扩展 service
        mixins: [ 'user' ],
    },
    config: { // 其它参数
        RPG: 'I AM Plugins',
    },
    "555": "666",  // 其它参数
}

插件类型可以是以下任一种:

  • 一个单独的外部模块.
  • 一个单独的内部文件夹.
  • 一个单独的文件.

插件返回值(支持任何形式)可进行全局注册, 调用如下:

    this.plugin.${filename}
    // or
    app.loadPlugin.${filename}

Middleware

中间件,只是全局进行注册,但是并不进行使用。 可以在 Router 中配置使用,或者手动使用 app.loadMiddleware.${filename}

如果想全局使用的话,可以在 config/middlewares.${default}.js 中单独配置,通过 mixins 进行全局顺序注册, 或者是 enable 参数进行注册,如下:

    mixins: [ 'bodyParse' ], // 自动进行全局顺序注册
    bodyParse: {
        enable: true, // 开启自动全局注册(true-全局注册, false-不开启)
        bo: 33,
        c: 3,
    },

Controller

config/controller.${default}.js 中可以通过 mixins 配置需要加载的 Controller 优先顺序, 默认加载所有 Controller 文件。 其它参数配置统一。

    mixins: [ 'user', 'cms' ], // 控制加载顺序

    user: {
        name: 'xiao ming, 红',
    },

另,Controller 文件需要以如下格式书写,如:

class UserController {

}
module.exports = UserController;

注入参数可通过 this.options 进行获取。 还支持以下参数:

this.appInfo
this.config
this.plugin
this.service
this.helper
this.logger

Service

待补充

class UserService {

    updateInfo() {
        // do something
    }
}

module.exports = UserService;

Router

待补充

module.exports = function(router) {
    router.get('/', this.controller.user.index);
    router.get('/test', router.new().routes());
    // 代理透传
    router.proxy('/p/fef91266a44c', {
        target: 'https://www.baidu.com',
        headers: {
            '007': '008',
        },
    });
};

Helper

待补充

    app.loadHelper.${filename}.${method};
    // ort
    this.helper.${filename}.${method};

Utility (系统工具类)

待补充

引用 2o3t-utility 工具库
