Question 1

Is it worth it to learn Fastify?

Accepted Answer

If you're in need of a high-performance, low-overhead web framework, it's definitely worth it to at least check Fastify out. Not everyone needs to know Fastify, but the number of features that Fastify comes with combined with its low memory usage and extensibility makes it obviously worth it for many different professionals. From Node.js developers to API and microservice developers, many developers find it worthwhile to have Fastify familiarity on their toolbelt.

Question 2

How long will it take to learn Fastify?

Accepted Answer

It shouldn't take more than a week or so to learn what Fastify is capable of or understand its component parts. What can take longer is mastering its implementation and the various layers of abstraction that can add complexity to your app. For example, Fastify's structured validation is done through type providers. That simplifies handling data, but you have to master defining those rules – and that's what takes time.

Question 3

How difficult is this Fastify Tutorial?

Accepted Answer

This Fastify course is called a tutorial for a reason: rather than dive in deep right away, it familiarizes developers with what parts of the Fastify web framework are familiar as well as those things that set it apart. If you've already got experience or familiarity with Express.js, Koa or Hapi, you'll have an easy time with this course. If you're relatively new to development frameworks, the foundational concepts are covered thoroughly to help you along.

Question 4

How long are skills in Fastify going to be relevant?

Accepted Answer

The development community loves comparing different frameworks and weighing in on whether or not any of them have a future: Fastify is often compared to its competitors Express and Koa. Fastify is a tried and tested framework with a mature ecosystem, it's simple, flexible – and it just works. There will continue to be competitors, and those may have unique use cases, but knowing how to develop in Fastify will remain relevant and useful for years to come.

Question 5

What's the best way to learn Fastify?

Accepted Answer

A video-based course like this tutorial course is one of the best ways to learn Fastify because it's broken into small nuggets of knowledge. You can skip past any sections you're already familiar with and then focus on the things about Fastify you're not familiar with. Once you're through the videos and have seen how the web framework works, practice environments and special sims give you challenges and places to build projects of your own.
