设计灵感
在项目中找到一个更加方便快捷的数据共享方案：
- 后续会完善文档和增加更多好用功能；
- 欢迎star、issue、pull requests，会进行更多改变；
如何使用呢？
1、npm安装依赖
npm install hy-event-store2、事件总线（event-bus）
const { HYEventBus } = require('hy-event-store')
const eventBus = new HYEventBus()
const whyCallback1 = (...payload) => {
console.log("whyCallback1:", payload)
}
const whyCallback2 = (...payload) => {
console.log("whyCallback1:", payload)
}
const lileiCallback1 = (...payload) => {
console.log("lileiCallback1:", payload)
}
eventBus.on("why", whyCallback1)
eventBus.on("why", whyCallback2)
eventBus.on('lilei', lileiCallback1)
eventBus.once("why", (...payload) => {
console.log("why once:", payload)
})
setTimeout(() => {
eventBus.emit("why", "abc", "cba", "nba")
eventBus.emit("lilei", "abc", "cba", "nba")
}, 1000);
setTimeout(() => {
eventBus.off("why", whyCallback1)
eventBus.off("lilei", lileiCallback1)
}, 2000);
setTimeout(() => {
eventBus.emit("why")
eventBus.emit("lilei")
}, 3000);3、数据共享（event-store）
const { HYEventStore } = require("hy-event-store")
const axios = require('axios')
const eventStore = new HYEventStore({
state: {
name: "why",
friends: ["abc", "cba", "nba"],
banners: [],
recommends: []
},
actions: {
getHomeMultidata(ctx) {
console.log(ctx)
axios.get("http://123.207.32.32:8000/home/multidata").then(res => {
const banner = res.data.data.banner
const recommend = res.data.data.recommend
// 赋值
ctx.banners = banner
ctx.recommends = recommend
})
}
}
})
// 数据监听
eventStore.onState("name", (value) => {
console.log("监听name:", value)
})
eventStore.onState("friends", (value) => {
console.log("监听friends:", value)
})
eventStore.onState("banners", (value) => {
console.log("监听banners:", value)
})
eventStore.onState("recommends", (value) => {
console.log("监听recommends", value)
})
// 数据变化
setTimeout(() => {
eventStore.setState("name", "lilei")
eventStore.setState("friends", ["kobe", "james"])
}, 1000);
eventStore.dispatch("getHomeMultidata")
