Fastify Course 🚀 The Performant Node.js Web Framework

This video will be a full introductory course to Fastify - a Node.js-based web framework/HTTP(s) server library. Fastify aims to provide the lowest overhead web framework based on Node.js. You can use Fastify to build a RESTful API, render templates like handlebars server-side (SSR), access databases with its excellent plugins. Fastify is plugin-based and extensible. It also supports hooks and decorators and its syntax is easy-to-learn and developer-friendly.
In the course, I introduce Fastify and its features, we talk about Fastify's advantages and disadvantages compared to other frameworks like Express, Koa and Hapi. Then we build a Fastify JSON API live and create a custom plugin which represents a controller. I demonstrate the JSON Schema validation mechanisms of Fastify. We then talk about Hooks and Decorators, which can be used to implement authentication with JWT, OAuth or any other authentication method and finally I demonstrate how to do database access with one of the DBA plugins - @fastify/mysql. Fastify also has plugins for MongoDB, Postgres, Redis and others.

wonderful introduction to "fastify", nicely explained and understandable by any beginner. thank you for your presentation.

[@nltech1]

Glad it was helpful!

Thank you for the super helpful and concise video! I had a question about the use of `process.exit(1)` being used on your catch statement; I know it's a common practice I see on a lot of YT channels, but if you read the modal that pops up when you hover over process.exit(), Node actually states it's unnecessary to include it in most cases. This is because that the try-catch block inherently will handle the error and exit accordingly, but you also run the risk of prematurely terminating any asynchronous functionality when you execute process.exit.
Just curious to hear what your take on that is, as I'm confused as well, haha. It's a habit I do myself, that's for sure.

NestJS has passed Express in GitHub stars

[@samsloanmusic1749]

Great video! I noticed you used a different syntax for database connection than most of the documentation I've seen. Usually it's the `connectionString` syntax. What is the difference?

Thank you! I use Cascadia Code: github.com/microsoft/cascadia-code

[@sumanmodak7859]

This is the worst ever framework when used with typescript. The developers have spoiled the documentation by including so many topic in a staggered way.

Do these two sentences correlate?

Its fine. Once ElysiaJS reaches 1.0 I’m rewriting
