Fiber

Fiber Γ¨ un framework web inspirato a Express costruito sopra Fasthttp, un motore HTTP molto veloce per Go. Progettato per semplificare le cose per uno sviluppo veloce con zero allocazione di memoria e le prestazioni in mente.

## ⚑️ Avvio rapido ```go package main import "github.com/gofiber/fiber/v2" func main() { app := fiber.New() app.Get("/", func(c *fiber.Ctx) error { return c.SendString("Hello, World πŸ‘‹!") }) app.Listen(":3000") } ``` ## πŸ€– Benchmark Questi test sono stati eseguiti da [TechEmpower](https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=plaintext) e [Go Web](https://github.com/smallnest/go-web-framework-benchmark). Se vuoi vedere tutti i risultati, visita la nostra [Wiki](https://docs.gofiber.io/extra/benchmarks).

## βš™οΈ Installazione Assicurati di avere Go ([download](https://go.dev/dl/)) installato. Versione `1.14` o superiore. Inizializza il tuo progetto creando una cartella e successivamente lanciando `go mod init github.com/your/repo` ([per maggiori info](https://go.dev/blog/using-go-modules)) da dentro la cartella. Dopo installa Fiber con il comando [`go get`](https://pkg.go.dev/cmd/go/#hdr-Add_dependencies_to_current_module_and_install_them): ```bash go get -u github.com/gofiber/fiber/v2 ``` ## 🎯 Caratteristiche - [Routing](https://docs.gofiber.io/routing) solido - Serve [file statici](https://docs.gofiber.io/api/app#static) - [Perfomance](https://docs.gofiber.io/extra/benchmarks) estreme - [Basso](https://docs.gofiber.io/extra/benchmarks) utilizzo di [memoria](https://docs.gofiber.io/extra/benchmarks) - [API endpoints](https://docs.gofiber.io/api/ctx) - Supporta Middleware e [Next](https://docs.gofiber.io/api/ctx#next) - Programmazione server-side [veloce](https://dev.to/koddr/welcome-to-fiber-an-express-js-styled-fastest-web-framework-written-with-on-golang-497) - [Template engine](https://github.com/gofiber/template) - [Supporto WebSocket](https://github.com/gofiber/websocket) - [Server-Sent events](https://github.com/gofiber/recipes/tree/master/sse) - [Rate Limiter](https://docs.gofiber.io/api/middleware/limiter) - Disponible in [15 lingue](https://docs.gofiber.io/) - E molto altro ancora, [esplora Fiber](https://docs.gofiber.io/) ## πŸ’‘ Filosofia I nuovi gopher che passano da [Node.js](https://nodejs.org/en/about/) a [Go](https://go.dev/doc/) hanno a che fare con una curva di apprendimento prima di poter iniziare a creare le proprie applicazioni web o microservizi. Fiber, come **web framework** , Γ¨ stato creato con l'idea di **minimalismo** e seguendo lo '**UNIX way**' , cosΓ¬ i nuovi gopher posso entrare rapidamente nel mondo di Go con un caldo e fidato benvenuto. Fiber Γ¨ **inspirato** da Express, il web framework piΓΉ popolare su internet. Abbiamo combiniamo la **facilitΓ ** di Express e **le pure prestazioni** di Go. Se hai mai implementato una applicazione web in Node.js (_utilizzando Express o simili_), allora i tanti metodi e principi ti saranno **molto familiari**. ## ⚠️ Limitazioni * Dato che Fiber utilizza unsafe, la libreria non sempre potrebbe essere compatibile con l'ultima versione di Go. Fiber 2.29.0 Γ¨ stato testato con la versioni 1.14 alla 1.18 di Go. * Fiber non Γ¨ compatibile con le interfacce net/http. Questo significa che non Γ¨ possibile utilizzare progetti come qglgen, go-swagger, o altri che fanno parte dell'ecosistema net/http. ## πŸ‘€ Esempi Qui sotto trovi molti dei piΓΉ comuni esempi.
