Consumer-Pgmq – Dead Letter Queue New Feature

I’m here to show the dead letter queue feature I implemented on the node.js module named consumer-pgmq, so if I set up to try 2 times and the message failed 2 times on the third time will send the message to the dead letter queue.

What is it?

Recently I discovered a feature queue on Supabase where I can implement a messaging queue using Postgresql database.

Spoiler if you have a Postgresql running out of Supabase you can use the queue feature too, you need only install the extension named pgmq. Link of instructions: https://github.com/pgmq/pgmq

But I noticed something missing on my opinion I didn’t find a package on Npm to make the polling from the message and passing to a function I defined to execute something, so as result of it I created the npm package named consumer-pgmq where integrate with Supabase and Postgresql
