Weaponizing Discord for Command and Control Across npm, PyPI, and RubyGems.org
Socket researchers uncover how threat actors weaponize Discord across the npm, PyPI, and RubyGems ecosystems to exfiltrate sensitive data.
@smt-lib/mobx
Advanced tools
解释: 在小程序开发中,总会遇到多页面需要使用同一数据的情况,从而产生了希望引入mobx、redux等数据状态管理框架的诉求。smt-mobx是小程序使用mobx的连接器,帮助开发者在小程序开发中使用mobx。mobx使用的是4.13.1版本。mobx官网
小程序种使用三方npm包方法,见npm使用说明
npm install @smt-lib/mobx
方法:createStoreManager
在onLoad或者attached时创建storeManager
createStoreManager
参数说明:
参数 | 类型 | 必填 | 默认值 | 说明 |
---|---|---|---|---|
target | Object | 是 | 当前上下文 | |
store | Object | 是 | store相关信息 | |
throttle | Function | 否 | swan.nextTick | 可throttle的函数 |
第二个参数说明:
属性名 | 类型 | 必填 | 默认值 | 说明 |
---|---|---|---|---|
store | Object | 是 | 当前上下文 | |
fields | Object/Array | 是 | 需要同步到小程序data上的数据。当类型为Object时,可以自定义挂载到data上的属性名 | |
actions | Object/Array | 否 | 修改store状态的动作,当类型为Object时,可以自定义挂载到storeManager上的方法名 |
返回值
|名称 |类型 |说明| |---- | ---- | ---- | ----|----| |destoryAll |Function | 清空所有storeManager | |updateImmediately |Function |及时同步store的状态更新到小程序data上| |actions中的方法|Function|actions中的所有方法,都会挂到storeManager|
** store示例 **
import { observable, action } from "mobx";
export const store = observable({
// 数据字段
a: 1,
b: 2,
addA: action(function () {
this.a++;
}),
addB: action(function () {
this.b++;
})
});
** 页面示例 **
import {createStoreManager} from '@smt-lib/mobx';
import {store} from './store';
Page({
data: {
// 默认数据
},
onLoad () {
// 将actions上的方法,绑到this.storeManager上
// 将fields上的数据,链接到this.data上
this.storeManager = createStoreManager(this, {
store,
fields: ['a', 'b'],
actions: ['addA', 'addB']
});
},
onUnload() {
// 在onUnload时需要清空绑定的storeManager
this.storeManager.destoryAll();
}
});
** 自定义组件示例 **
import {createStoreManager} from '@smt-lib/mobx';
import {store} from './store';
Component({
properties: {
// 默认数据
},
lifetimes: {
attached() {
// 将actions上的方法,绑到this上
// 将fields上的数据,绑到this.data上
this.storeManager = createStoreManager(this, {
store,
fields: {
aa: 'a',
bb: 'b'
},
actions: {
myAddA: 'addA',
myAddB: () => store.addB
}
});
},
detached() {
// 在detached时需要清空绑定的storeManager
this.storeManager.destoryAll();
}
},
methods: {
updateNum() {
this.data.aa // 获取store中的a
this.storeManager.myAddA(); // 调用action中的addA方法
this.storeManager.updateImmediately();
}
}
});
