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 🙏

Getting Start

安装

# npm
npm i ts-class-decorators

# yarn
yarn add ts-class-decorators

tsconfig.json

必须打开装饰器开关

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  }
}

说明

为了快速书写装饰器

例子

为快速加入类

基础使用模式

装载一种类型的类

文档

装饰器基础

export declare class DecoratorUtil {
  // 获取一个 类装饰器
  class<T = any>(
    ...paths: Meta.KeyType[]
  ): ClassBuilder<T, import('./ClassBuilder').ClassDecorator<T>>;
  // 创建一个 函数装饰器
  method<T = any>(
    ...paths: Meta.KeyType[]
  ): MethodBuilder<T, import('./MethodBuilder').MethodDecorator<T>>;
  // 获取一个类的元数据
  getMeta<T = any>(constructor: Function, ...paths: Meta.KeyType[]): T;

  // 类元数据的根,建议使用symbol,不轻易被外界修改
  get root(): string | number | symbol;
}

类装饰器

export declare class ClassBuilder<T = any, R = ClassDecorator<T>> {
  readonly _root: Meta.KeyType;
  // 使用 Object.assign 插入到数据中
  assign(): this;
  // 作为一个数组进行插入,倒序
  arrayDesc(): this;
  // 作为一个数组进行插入,正序
  arrayAsc(): this;
  // 作为一个数组进行插入,正序
  array(): this;
  /**
   * 加入路径
   * root.foo.bar 则 util.addPaths('foo','bar')
   *
   * 注意:
   * * `{name}` 为构造函数名 constructor.name
   **/
  addPaths(paths: Meta.ManyKeyType): this;
  // 给出默认数据
  value(value: T): ClassBuilder<T, ClassDecorator_hasDefault<T>>;
  // 给出默认数据的函数
  defaultValueFunc(
    valFunc: NonNullable<this['_def']['fn']>
  ): ClassBuilder<T, ClassDecorator_hasDefault<T>>;
  // 可以执行函数
  func(fn: this['_fns'][0]): this;
  // 生成装饰器
  make(): R;
}

函数装饰器

export declare class MethodBuilder<T = any, R = MethodDecorator<T>> {
  readonly _root: Meta.KeyType;
  // 使用 Object.assign 插入到数据中
  assign(): this;
  // 作为一个数组进行插入,倒序
  arrayDesc(): this;
  // 作为一个数组进行插入,正序
  arrayAsc(): this;
  // 作为一个数组进行插入,正序
  array(): this;
  /**
   * 加入路径
   * root.foo.bar 则 util.addPaths('foo','bar')
   *
   * 注意:
   * * `{key}` 为函数名
   **/
  addPaths(paths: Meta.ManyKeyType): this;
  // 给出默认数据
  value(value: T): MethodBuilder<T, MethodDecorator_hasDefault<T>>;
  // 给出默认数据的函数
  defaultValueFunc(
    valFunc: NonNullable<this['_def']['fn']>
  ): MethodBuilder<T, MethodDecorator_hasDefault<T>>;
  // 可以执行函数
  func(fn: this['_fns'][0]): this;
  // 生成装饰器
  make(): R;
