Usage

Streaming of logs

//in index.ts file

import * as logger from "@backendalpha/pancaplogger/dist/logger";

export logger.init(function () { });

logger.error({ message: "error",tag:TagId,additionalInfo: {message: "Some additional message",otherData:"Some additional data"}}); logger.info({ message: "info",tag:TagId,additionalInfo: {message: "Some additional message",otherData:"Some additional data"}}); logger.debug({ message: "debug",tag:TagId,additionalInfo: {message: "Some additional message",otherData:"Some additional data"}}); logger.warn({ message: "warn",tag:TagId,additionalInfo: {message: "Some additional message",otherData:"Some additional data"}}); logger.exception({ message: "exception",tag:TagId,additionalInfo: {message: "Some additional message",otherData:"Some additional data"}});

Querying of logs

//In index.ts file

import * as logger from "@backendalpha/pancaplogger/dist/logger";

ExceptionHandler.setExceptionHandler(false);

logger.init(function () { });

export {logger}

** For Query-query(fromTimeStamp:"value",toTimeStamp:"value",tagId:"value",level:"value",pageNumber:"value",pageSize:"value");
