miniprogram-logger

It is used to logger and gather statistics of users' behavior by using wx.reportAnalytics

example

import { logger } from "miniprogram-logger";
logger.debug("action", "log something", correlation_id);
logger.info("action2", "info or content", correlation_id);
logger.warn("action2", "important messages", correlation_id);
logger.error("action2", { err: Exception }, correlation_id);

// 开始计时开始
logger.time("timer-label", { action: "", param: "" });
// 完成计时结束
logger.timeEnd("timer-label");

// 耗时统计一次写入
logger.timeLog("action", 1000, { param: "xxx" }, "request-ID", { errMsg: "" },"type");
logger.timeLog({
    action: string,
    duration: number,
    parameter: any,
    requestId: string,
    result: string | any,
    ...
});

// 用户行为统计
logger.telemetry("do something", { p: "参数" }, {});

// 全局参数设置
logger.setContext("key", "value");

API

Const object

• logger 统一的默认 logger 对象，类似 console api 方式封装下面全部 (推荐使用)
• defaultCounter 默认计数上报对象
• defaultLogManager 本地日志管理对象
• defaultLogReporter 自定义分析日志上报对象
• defaultTimer 耗时统计上报对象
• defaultTelemetry 用户行为统计上报对象

Function

• inject() listen and log the app onError/onPageNotFound
• guid() get a UUID like string
• isLogLevel(level:any) level is LogLevel or not

Class

• ConsoleManager
• CounterReportMonitor
• LogReporter
• LogManager
• LogObject
• LogLevel
• TelemetryReporter
• TimeReporter
• PerformanceObject

Install

npm i miniprogram-logger -S

1. Create the data event in the MiniProgram backend as follow:(Reference: )

https://developers.weixin.qq.com/miniprogram/analysis/custom/

自定义记录表

• 
• 
• 

id和record_time 默认会自动生成

下列所有非number类型均对应string

DefaultLogObject

日志对象

{
    "level": "LogLevel",
    "action": "string",
    "content": "any",
    "user": {},
    "correlation_id": "string",
    "id": "string",
    "timestamp": "string"
}

上报事件名log; 表结构

字段	类型	说明
id	string	单条记录过滤 ID
level	string	日志级别
action	string	操作
content	string	内容
correlation_id	string	关联 ID
user	string	客户端脱敏数据
timestamp	string	ISO 时间戳

TelemetryObject

记录 Telemetry

{
    "id": "string",
    "action": "string",
    "param": "any",
    "extension": {
        "debug_correlation_id": "string",
        "process_time": "number",
        "timestamp": "string"
    },
    "user": {
        "app_name": "string",
        "app_id": "string",
        "open_id": "string",
        "union_id": "string"
    }
}

自定上报默认事件名telemetry; 表结构

字段	类型	说明
id	string	单条记录过滤 ID
action	string	操作
param	string	参数
extension	string	其它数据
user	string	客户端脱敏数据

TimeReporter

时间统计对象

{
    "action": "string",
    "duration": "number",
    "param": "any",
    "correlation_id": "string",
    "result": "any",
    "type": "string",
    "user": "any",
    "id": "string",
    "timestamp": "string"
}

自定上报默认事件名time;

表结构

字段	类型	说明
id	string	单条记录过滤 ID
action	string	操作
time	number	操作耗时
param	string	参数
correlation_id	string	关联 ID
result	string	操作结果
type	string	操作分类
user	string	客户端脱敏数据
timestamp	string	ISO 时间戳

App Error

import { inject } from "miniprogram-logger";
inject(); //自动记录全局错误
