  • Deploy serverless Lambda TypeScript API with function url using AWS CDK
    Fastify is a JavaScript web framework that intentionally aims for low overhead and speed over other frameworks such as express. I have arbitrarily chose it for this tutorial, but any web framework that supports routing will work. - Source: dev.to / 19 days ago

For example, fastify is a web framework in NodeJS and only the core structure needed for routing and requests are within the main fastify module.

  • What is the point of uWSGI?
    I'm looking at the WSGI specification and I'm trying to figure out how servers like uWSGI fit into the picture.
