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 🙏

Super Simple DI

简介

一个简单的依赖注入工具,用于TypescriptNode.js平台。

用法

  • 导入模块

    使用import语句进行导入。

    import * as ssimpleDI from 'simple-di';
  • 声明 Bean

    使用Component装饰器声明需要注入成为 Bean 的组件。

    @ssimpleDI.Component
    class A {
        // 省略该类的代码
    }
  • 导入 Bean 并初始化

    在 Nodejs 应用入口里使用Module装饰器导入前面声明的 Bean ,并调用init()方法进行初始化。

    // 省略导入的模块
    
    @ssimpleDI.Module([
        A,
        // 省略其它 Bean
    ])
    class Module {}
    
    ssimpleDI.init()
    
    // 省略其它的代码
  • 使用getInstance()方法从 Bean 容器中获取实例

    // ...
    
    let a = ssimpleDI.getInstance<A>(A);
    
    // ...

实例

  • 目录结构

    .
    ├─dist
    ├─src
    │  ├─a.ts
    │  ├─b.ts
    │  └─main.ts
    └─others
  • 文件内容

    // file: a.ts
    
    import * as ssimpleDI from 'simple-di';
    
    @ssimpleDi.Component
    export class A {
        a = 'a';
    }
    // file: b.ts
    
    import * as ssimpleDI from 'ssimple-di';
    import { A } from './a.ts';
    
    @ssimpleDi.Component
    export class B {
        b = 'b';
    
        constructor(private a: A) {}
    
        getA(): A {
            return this.a;
        }
    }
    // file: main.ts
    
    import { strict as assert } from 'assert';
    import * as ssimpleDI from 'ssimple-di';
    import { A } from './a.ts';
    import { B } from './b.ts';
    
    @ssimpleDI.Module([
        B,
        A
    ])
    export class Module {}
    
    ssimpleDI.init();
    
    let a = ssimpleDI.getInstance<A>(A);
    let b = ssimpleDI.getInstance<B>(B);
    
    assert.strictEqual(a.a, 'a');  // OK
    assert.strictEqual(b.b, 'b');  // OK
    assert.deepStrictEqual(b.getA(), a);  // OK
