micro-utils

TOC

简介

描述：micro-utils 是通用抽象工具类，里面封装了如 "indexDB" 数据库使用、“SocketEmitter”消息订阅、“cache”前端本地存储...等常用公共方法，使用微应用脚手架构建项时目已默认安装，可直接使用。

Git 仓库地址：https://git.topvdn.com/micro-business/micro-utils

依赖安装：

//示例为yarn安装，也可以使用npm安装
yarn add @zenview/micro-utils

使用示例：

//使用示例
import { LM_DB, cache } from '@zenview/micro-utils';

const db = new LM_DB('functionCount');

const headers = {
  Authorization: cache.getCache('token', 'session'),
};

cache

前端缓存：封装了 sessionStorage、localStorage、Cookie 的读写方法。 注意：type 不传默认为“local”，存储对数据使用了 JSON.stringify 处理，引用类型无需再次转换。

代码演示

//使用示例
import {cache } from '@zenview/micro-utils';

cache.setCache('cache', data, 'session');

const data = cache.getCache('cache', 'session'),

API

type CacheType = 'session' | 'local' | 'cookie';

cache.getCache(key: string, type?: CacheType): any;
cache.setCache(key: string, value: any, type?: CacheType): any;
cache.getUserCache(key: string, type?: CacheType): any;
cache.setUserCache(key: string, value: any, type?: CacheType): any;

Params

LM_DB

前端数据库 indexDB 公共方法

代码演示

//使用示例
import { LM_DB } from '@zenview/micro-utils';
const db = new LM_DB('dbName');
//存储
db.put({ id: 123, ...data }).then((res) => {
  console.log(res);
});

//读取
const res = await db.get({ id: 123 });

API

class LM_DB implements LMDBInterface {
  constructor(schemaName: string);
  put(params: { [key: string]: any; id: string; expireTime?: number } & any): Promise<null>;
  get(params: { id: string }): Promise<{ [key: string]: any }>;
}

Params

SocketEmitter

前端消息事件订阅方法，包含 webSocket 使用

代码演示

//使用示例

//关闭订阅
SocketEmitter.off('emitterName', (data) => {});
//开启webSocket
SocketEmitter.connect('/socket.io', null);

API
