# @fesjs/plugin-vuex
|
||
|
||
::: tip
|
||
vue3+ 官方推荐使用[pinia](./pinia),不在推荐使用 vuex。
|
||
:::
|
||
|
||
## 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
|
||
|
||
约定模式,module 和 plugin 定义放在 stores 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。
|
||
|
||
```
|
||
└── src
|
||
├── pages
|
||
│ └── index.vue
|
||
└── stores
|
||
│ └── foo
|
||
│ │ └── bar.js
|
||
│ ├── counter.js
|
||
│ ├── plugin-logger.js
|
||
│ ├── user.js
|
||
└── app.js
|
||
```
|
||
|
||
::: tip
|
||
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:
|
||
|
||
```json
|
||
{
|
||
"dependencies": {
|
||
"@fesjs/fes": "^2.0.0",
|
||
"@fesjs/plugin-vuex": "^2.0.0"
|
||
}
|
||
}
|
||
```
|
||
|
||
## 配置
|
||
|
||
在 `.fes.js` 中配置:
|
||
|
||
```js
|
||
export default {
|
||
vuex: {
|
||
strict: true, // 开启严格模式
|
||
},
|
||
};
|
||
```
|
||
|
||
## 场景使用
|
||
|
||
先定义在 stores 下定义 user 模块,包含嵌套模块
|
||
|
||
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';
|
||
|
||
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)

||
|
||
