fastify-auth VS fastify

100% compatibility with already built fastify plugin, so things like authentication can be done in an already good way, like with fastify-auth

Fastify as its core is okay. Not great, but OK. But plugins (official ones) made me struggle. For example, I couldn't figure out how to get fastify-auth plugin to work. It seems like plugins, even official, do not keep the same standards across whole ecosystem. It would be nice if all would have TS examples.

So the example is here I copied it as is, just adapting routes. Now to my understanding, I need either sessions or cookies so that when the user hits only one time ` http://127.0.0.1:3000/auth-multiple` all sequential calls to any secured api would verify the token.

For example, Fastify allows us to write better and cleaner asynchronous code by parsing JSON requests. With Fastify plugins, you don’t have to install multiple npm packages from different authors to perform common tasks like authentication and validation.

For example, Fastify removed the instanceof operatorfrom its codebase because it was causing problems for those developers that rely on jest as a testing framework.

Both are frameworks but NextJs is for Forntend (web app in browser that use ReactJs under the hood) and NestJs is for Backend (server app running on a server witch use Express or Fastify). The only thing similar between them is the typed language in which they were written.

Restify & Fastify Hapi

Let's create a sample Node API project we can work with throughout to build a new docker image. We will leverage Fastify to create an API that we configure via the fastify-cli.

Fastify

In setting out to build this service, we wanted to use gRPC for its APIs. We’ve been reaching for REST when building APIs so far, primarily out of necessity, i.e., our public APIs needed auto-generated client SDKs and docs for developers working with them. We built those APIs with Fastify and Typebox but felt burned by a code-first approach to generating an OpenAPI spec. I’ll spare you the details and save that experience/learning for another article. Suffice it to say we love gRPC’s schema-first approach. This blog post summarizes our feelings well

Fastify – Fast and Low overhead web framework

Custom Functions are powered by Fastify (a light-weight Node.js framework that claims to be faster than Express.js), so they’re extremely flexible.
