critical-error

Provides a simple interface to send messages to a pre-configured SNS endpoint, using @aws-sdk/client-sns.

All messages are also logged to console.error.

A process uncaughtException handler is also installed which logs uncaught exceptions.

Usage

var critical = require('critical-error');

// configure somewhere once before use:
critical.configure({TopicArn:"arn:aws:yourarnhere", region:"the-topics-region"});

critical("Oh no! Super bad error D:")

Options

All options are passed to the AWS SDK PublishCommand creation, apart from region which is used when creating the AWS SNS Client object.

Usage in shortlived processes

critical() is asynchronous but does not provide a callback (since there is no sensible way to handle errors). If you need to wait for messages to be sent (for instance due to running as a serverless function), then use:

// call callback when an in-flight critical() request is completed:
critical.waitForCompletion(callback);

// await the completion of an inflight request:
await critical.waitForCompletion();
