Type-Safe Fastify, JavaScript sandboxing and other Adventures in Nodeland

Hi Folks, Last week I have been traveling to visit one of the first companies to adopt Platformatic. I'm excited! Nevertheless, this issue covers the usual batch of releases and articles. Check them out!

What if I told you Fastify has first-class typescript support, allowing for typed requests and replies? And you could use those types to validate the incoming data, avoiding potential security and consistency issues.

In my latest youtube tutorial, Type-Safe Fastify I show how to integrate @sinclair/typebox with Fastify using @fastify/type-provider-typebox!

In Part 12 of the "Building the Unscalable Queue System" series, we finished the remaining tasks in the README. We also started making it scalable by using PostgreSQL instead of SQLite and electing a leader. Check it out at https://youtu.be/h2EITPom6AM.
