let myLog=jsonLog({logApp:"myApp",logName:"structLog-start",logMsg:{"name":"shendl",'age':22}})

export function jsonInfo({logApp,logName,logMsg,logVersion='1.0.0',logLevel='info'}:{

logApp:string,logName:string,logMsg:any,logVersion?:string,logLevel?:string

})

jsonInfo is log function whose logLevel is info.

Info is enabled on product stage.

export function jsonDebug({logApp,logName,logMsg,logVersion='1.0.0',logLevel='debug'}:{

logApp:string,logName:string,logMsg:any,logVersion?:string,logLevel?:string

})

jsonDebug is log function whose logLevel is debug.

Debug is enabled on develop or test stage.

export function jsonWarn({logApp,logName,logMsg,logVersion='1.0.0',logLevel='warn'}:{

logApp:string,logName:string,logMsg:any,logVersion?:string,logLevel?:string

})

Warn log indicate that program is on unnormal status.

export function jsonError({logApp,logName,logMsg,logVersion='1.0.0',logLevel='error'}:{

})

Warn log indicate that program is on error status.

export let logStrs:string[]=[]

All log are filled into logStrs.This is an string array.

You can write logStrs into storage or send logStrs to server.

Then you can parse all logs.

Default log threshold is info.

So debug log will not write out.

You can change this variant to debug,info,warn,error.
