Another nice feature is that it supports JSON Schema to validate input and output of HTTP handlers (more on that later).
First we will install fastify, middie, and some commonly used middleware:
yarn add fastify middie cors frameguard x-xss-protection
To give you an idea of using the optional JSON Schema, let’s validate and strongly type a
querystring so that it must contain
Here you can see that we’re not only using TypeScript, but also additional JSON schema to validate and ensure that our API output is exactly what we want it to be.
On line 14, we see that our API looks almost identical to what we would typically expect to see from an Express API. This makes it easy for Express developers to quickly jump over to Fastify and stay productive. So it’s an easy replacement with a great performance boost!
Microfrontends are a great way to speed up and scale app development, with independent deployments, decoupled codebases, and autonomous teams.
