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 🙏

happy-vuex

v1.0.5

Published

基于Vuex进行封装,赋予Vuex更愉快的使用体验

Readme

对Vuex进行简单的封装,提供更友好全局状态管理。

npm install happy-vuex --save

使用方法

组件内使用

// 更新 a 为 2
this.setData(['a', 2])
// 整体更新该模块下数据
this.setData(['', {a: 2, b: 2}])
// 整体还原该模块下数据
this.init();

action内使用

// 更新 a 为 2,其他同上
commit("setData", ["a", 2]);

Vuex模块内的写法


import {cloneDeep, commonMutations} from "happy-vuex";

const initstate = {
    a: 1,
    b: 1,
};
const getters = {};
const actions = {
    setDataDemo({commit}) {
        // 更新值 a 为 2
        commit("setData", ["a", 2]);
    },
};
const mutations = {
    ...commonMutations(initstate),
};
export default {
    namespaced: true,
    state: cloneDeep(initstate), // 深克隆,切断引用关联
    getters,
    actions,
    mutations
}

模块化命名

const store = new Vuex.Store({
    modules: {
        home: ,
    }
})

组件内注册

// 映射Vuex状态到组件内部,即可通过this.a调用
computed: mapState({
    ...mapStateToProps('home', ['a', 'b']),
}),
// 如果与其他计算属性共用,可用如下写法
computed: {
    ...mapState({
        ...mapStateToProps('home', ['a']),
    }),
}
// 在vue独立组件内注册,即可用setData和init方法
methods: {
    ...mapMutations({
        setData: 'home/setData',
        init: 'home/init', // 如不需要init方法可省略
    }),
}

// 组件内更新状态,即可调用setData
this.setData(["a", 2]); // 更新a值为2
