## 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`和`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
|
||||
在 `package.json` 中引入依赖:

```
|
||||
|
||||
## 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,如:
|
||||
```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
