## 介绍
集成vuex插件
增强vuex导出所有的mutations、actions和getter的事件类型编辑器提示
增强vuex导出所有的`mutations``actions``getter`的事件类型,编辑器提示
约定模式module和plugin定义放在sotres目录下文件名包含plugin被解析为插件无需额外配置定义即可用。

::: tip
vuex的提供的api直接导入使用
为了防止`fesjs`与`vuex`的export冲突fesjs不提供导出vuex的任何api。你可以直接使用vuex的api
```js
import { useStore } from 'vuex';
```
:::
## 启用方式
`package.json` 中引入依赖:
@ -31,25 +45,141 @@ export default {
```
## 场景使用
vuex定义模块之后使用getter、mutation、action都是通过传入字符路径
```js
import { useStore } from 'vuex';
const store = useStore();
store.getters['user/address']
store.commit('counter/increment')
store.dispatch('user/login')
```
先定义在stores下定义user模块包含嵌套模块
使用该插件,可以利用导出的事件类型,如:
stores/user.js
```js
export default {
namespaced: true,
state: () => ({
name: 'aring',
age: 20
}),
actions: {
login() {
return new Promise((reslove) => {
setTimeout(() => {
console.log('login');
reslove('OK');
}, 1000);
});
}
},
modules: {
address: {
state: () => ({
province: '广东省',
city: '深圳市',
zone: '南山区'
}),
getters: {
address(state) {
return state.province + state.city + state.zone;
}
}
}
}
};
```
stores/foo/bar.js
```js
export default {
namespaced: true,
state: () => ({
count: 0
}),
mutations: {
increment(state) {
state.count++;
}
},
getters: {
doubleCount(state) {
return state.count * 2;
}
},
actions: {
asyncIncrement({ commit }) {
setTimeout(() => {
commit('increment');
}, 2000);
}
}
};
```
::: tip
导出的`mutations`、`actions`和`getter`的事件类型,将会按文件命名;
如`ACTION_TYPES.user.login`指向user模块中actions的login方法
如`GETTER_TYPES.user.address`指向user模块中嵌套的address getter
如`MUTATION_TYPES.fooBar.increment`指向foo/bar模块中mutations的increment方法
:::
在vue文件中使用store
```vue
<template>
<div>
<h4>Vuex</h4>
<div><button :disabled="disabled" @click="login">async login</button></div>
<div><button @click="fooBarIncrement">foo/bar{{fooBarDoubleCount}}</button></div>
<div>{{address}}</div>
</div>
</template>
<config>
{
"name": "store",
"title": "vuex测试"
}
</config>
<script>
import { computed, ref } from 'vue';
import { useStore } from 'vuex';
import { MUTATION_TYPES, GETTER_TYPES, ACTION_TYPES } from '@fesjs/fes';
const store = useStore();
store.getters[GETTER_TYPES.user.address]
store.commit(MUTATION_TYPES.counter.increment)
store.dispatch(ACTION_TYPES.user.login)
export default {
setup() {
const store = useStore();
console.log('store==>', store);
const disabled = ref(false);
// 可以利用导出的事件类型不再通过字符传入store.getters['user/address']
return {
address: computed(() => store.getters[GETTER_TYPES.user.address]),
disabled,
login: () => {
disabled.value = true;
store.dispatch(ACTION_TYPES.user.login).then((res) => {
window.alert(res);
disabled.value = false;
});
},
fooBarIncrement: () => store.commit(MUTATION_TYPES.fooBar.increment), // foo/bar目录会解析成驼峰fooBar
fooBarDoubleCount: computed(() => store.getters[GETTER_TYPES.fooBar.doubleCount])
};
}
};
</script>
```
::: tip
由于该插件注册在onAppCreated中如果在onAppCreated及之前使用useStore时获取不到vuex实例
`fesjs`导出了vuex实例`store`如在app.js文件中
```js
import { store, GETTER_TYPES } from '@fesjs/fes';
console.log(store.getters[GETTER_TYPES.user.address])
```
:::
## vuex插件
stores文件夹下的文件名包含plugin被解析为插件vuex插件写法参考[官方文档](https://next.vuex.vuejs.org/guide/plugins.html)
## API
### store
* 类型 `Object`
* vuex实例
### MUTATION_TYPES
* 类型 `Object`
* mutation的所有事件类型
