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 🙏

Codecov Coverage NPM Version Build Release

基于 Redux、React-Redux、Redux-saga、Typescripe 的状态管理库

Dxjs 能做什么

Dxjs 是一个 基于 redux-saga 和 typescript 的状态管理库,它在 redux-saga 的基础上新增了一些钩子,让你能够在数据流的任意阶段插入逻辑,

基础特性

  • Symbol, 解决 Action Type 冲突,通过方法名换取 Action, 免去定义烦恼
  • 基于 Class, 更多特性可用:私有属性、装饰器、继承
  • Typescript: 减少类型错误,增强代码的鲁棒性
  • 增强器: 各个阶段植入逻辑,减少模板代码

安装

npm install react-redux @dxjs/core @dxjs/common

# 采用 yarn
yarn add react-redux @dxjs/core @dxjs/common

在 taro 中安装依赖

npm install @tarojs/redux @tarojs/redux-h5

# 在 config/index.js 中设置
alias: {
  "react": require.resolve("@tarojs/taro"),
  "react-dom": require.resolve("@tarojs/taro"),
  "react-redux": require.resolve("@tarojs/redux"),
}

DxModel


export class ExampleModel extends DxModel {
  state = { count: 1 };

  @Reducer('ns/count')
  coustActionReducer(count: number): void {
    this.state.count += count;
  }

  @Reducer()
  updateCount(count: number): void {
    this.state.count += count;
  }

  @Effect('ns/asyncCount')
  *asyncUpdateCount(payload: number): Generator {
    const count = yield this.$call(delayGet, payload);
    yield this.$put((ExampleModel as DxModelContstructor).updateCount(count));
  }

  @Effect()
  *delayUpdate(payload: number): Generator {
    const count = yield this.$delay(1000, payload);
    yield this.$put((ExampleModel as DxModelContstructor).updateCount(count));
    return (count as number) + 10;
  }
}

快速开始

创建一个 Dx 实例

为了方便,create 会返回一个 React Component, 如果不想返回 Component, 可以使用 Dx.createStore

import { Dx } from "@dxjs/core"

const DxApp = Dx.create({
    models: [],
    reducerEnhancer: [],
})

创建 model

只需要继承 DxModel, 你可以通过 Dx.collect 来收集 model, 或者手动传入到 Dx.create 中

import { Dx, DxModel } from "@dxjs/core"

@Dx.collect()
class UserModel extends DxModel {}

定义 reducer 和 effect

利用装饰起 Effect 和 Reducer 来标识这是一个 effect 还是 reducer, 他们还接受一些参数

import { Dx, DxModel } from "@dxjs/core"
import { Effect, Reducer } from "@dxjs/core"

@Dx.collect()
class UserModel extends DxModel {
    @Reducer()
    update(payload) {
        return { payload }
    }

    @Effect()
    update(payload) {
        this.$call(service)
    }
}

获取Action

通过 Dx.getModels 获取到所有的 model,注意获取到的都是构造函数,只是内部把所有的 effect 和 reducer 都挂在了静态方法上,所以看起来像直接调用了实例方法一样,实际上第二个参数设为 true 会直接调用 dispatch, 否则则会返回 action

import { Dx } from "@dxjs/core"
Dx.getModels().UserModel.update("some", true)
Dx.getModels('UserModel').update("some", true)
Dx.getModels('Use').update("some", true)
Dx.getModels(/^Use/)[0].update("some", true)
