fastify-rate-limit VS fastify-swagger

fastify-rate-limit is a plugin for the Fastify web framework that provides an easy-to-use interface for implementing rate limiting in your Node.js applications. The plugin lets you specify the maximum number of requests a client can make within a specific timeframe and the response to send when this limit is exceeded.

We can do it by our own, but i'll use for now Fastify-rate-limit plugin to achieve this easily.

With Speakeasy, you can create client SDKs based on an OpenAPI specification. Fastify ships with the @fastify/swagger plugin, which provides convenient shortcuts for generating good OpenAPI specifications. We'll start this tutorial by registering @fastify/swagger in a Fastify project to generate a spec.

First let’s get our current OpenAPI specification out of Fastify and onto the file system. If you have not added the https://github.com/fastify/fastify-swagger plugin first go do that. Then use this simple script I called generate-spec.ts to write your OpenAPI specification to the filesystem.

The fastify-swagger docs has an example https://github.com/fastify/fastify-swagger

@fastify/swagger is a fastify plugin to serve a Swagger UI, using Swagger (OpenAPI v2) or OpenAPI v3 schemas automatically generated from your route schemas, or from an existing Swagger/OpenAPI schema.

On the Node.js framework side of things, Fastify has support for Swagger with the fastify-swagger plugin.

With this approach, backend can be any programming languages that support OpenAPI or Swagger. Personally, I use fastify-swagger; but I can also be things like Python's FastAPI or Golang's Gin/Buffalo/Native.
