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.

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:")

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

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();

• add .waitForCompletion()

• Updated to use aws-sdk v3, depending only on @aws-sdk/client-sns instead of the whole sdk
