Error Logging

A package to catch errors in apps and logs a formatted stack trace.


Can grab some information from global error events, or more data if using the AvExceptions.submitError function.



npm install @availity/exceptions-core


yarn add @availity/exceptions-core


AvExceptions requires a logging function to call. And its recommended to have code in place to call AvExceptions.submitError(error) for better stack traces.

import AvExceptions from '@availity/exceptions-core';

function exampleLogging(logMessage) {
// send to api

const ExampleExceptions = new AvExceptions(exampleLogging);

Log function

The log function will receive a message object with these keys:

  • errorDate - a formatted date string
  • errorName - the name from the error object.
  • errorMessage - the message from the error object.
  • errorStack - a formatted stack trace string
  • appId - the defined appId or 'N/A'
  • totalHits: how many times this error message has occurred since page load
  • currentHits: how many times this error message has occurred since last log
  • userAgent - browsers userAgent
  • userLanguage - language value from browser
  • referrer - document referrer
  • host - current domain
  • url
  • appVersion
  • sdkVersion



accepts an error object and submits it to be formatted and logged.


if a value is passed in, sets class's enabled flag true/false based on value.

returns boolean enabled flag value.

if class is not enabled, it will not call the log function.


if a string or number value is passed in, sets appId value.

returns appId.

if no appId is defined, 'N/A' will be in the message object


repeat time is the time AvExceptions will wait after an error is called before it will log another error with the same message.

if a number is passed in, this sets repeat time value. The default is 5 seconds.

returns repeatTime value.
