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 🙏

使用方法


  1. 安装

    npm install v-vuex
  2. 注入 store

    import VuexSaga from "v-vuex";
    new Vuex({
      ...,
      plugins: [
        VuexSaga({
          sagas,   // 全局sagas, 可以为[]
          ...
        })
      ]
    }) // 注入全局store
  3. 与 model 进行链接

    import { connect } from "v-vuex";
    export default connect({
      ns: "demo",
      state: {
        demo: "1242"
      },
      mutations: {
        setDeom(payload) {
          this.demo = payload;
        }
      },
      actions: {
        getDemo1(val) {
          this.commit("setDeom", val);
        },
        *getDemo2(val) { // 和redux saga写法一样的
          yelid call(api.fetch, params); // 触发vue中的请求
          yelid put(`${models.ns}/${mutationName}`, valueJson); // 触发vue中的mutation
        }
      }
    });
  4. 使用

    // vue组件中使用
    import model from "../../models/test";
    model.getDemo1(123); // 这个返回值,随使用者返回
    model.getDemo2(123); // 这个返回值,随使用者返回
    ~~~基本介绍;

  1. 数据模型(model)概念,用法

    说到模块前, 我要先说说使用 vuex 官方的 model(也叫 module)的一些不足首先

    • 官方定义的模块中的方法不能直接使用, 必须配合 dispatch,commit 等方法, 还要拼接 action 字符串(主要是有命名空间的情况下)
    • 官方定义的模块,默认不支持热加载,或者需要写大量模块注入的方法(不方便)
    • 在主流 ide 中, 对自动代码提示不友善, 当用到某个 action 的时候,传参的时候还要查看 action 是怎么定义的
    • 使用的时候不够简洁, 比如还要手动去调用 mapActions/mapGetters..
  2. 2.x 版本支持在 vue 中使用 redux-saga【最新版本 1.1.3】 编写 actions,用法同普通 model 中的 action 一样
