Fiber — это веб фреймворк, который был вдохновлен Express и основан на Fasthttp, самом быстром HTTP-движке написанном на Go. Фреймворк был разработан с целью упростить процесс быстрой разработки высокопроизводительных веб-приложений с нулевым распределением памяти.
## ⚡️ Быстрый старт
```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 👋!")
})
app.Listen(":3000")
}
```

## ⚙️ Установка
Убедитесь, что Go установлен ([скачать](https://go.dev/dl/)). Требуется версия `1.17` или выше.
Инициализируйте проект, создав папку, а затем запустив `go mod init github.com/your/repo` ([подробнее](https://go.dev/blog/using-go-modules)) внутри этой папки. Далее, установите Fiber с помощью команды [`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

## 💡 Философия
Новые Go-программисты, которые переключаются с [Node.js](https://nodejs.org/en/about/) на [Go](https://go.dev/doc/), имеют дело с очень извилистой кривой обучения, прежде чем они смогут начать создавать свои веб-приложения или микросервисы. Fiber, как **веб-фреймворк**, был создан с идеей **минимализма** и следовал **принципу UNIX**, так что новички смогут быстро войти в мир Go без особых проблем.
Fiber **вдохновлен** Express, самым популярным веб фреймворком в Интернете. Мы объединили **простоту** Express и **чистую производительность** Go. Если вы когда-либо реализовывали веб-приложение на Node.js (_с использованием Express или аналогичного фреймворка_), то многие методы и принципы покажутся вам **очень знакомыми**.
Мы **прислушиваемся** к нашим пользователям в [issues](https://github.com/gofiber/fiber/issues), Discord [канале](https://gofiber.io/discord) _и в остальном Интернете_, чтобы создать **быстрый**, **гибкий** и **дружелюбный** веб фреймворк на Go для **любых** задач, **дедлайнов** и **уровней** разработчиков! Как это делает Express в мире JavaScript.
## ⚠️ Limitations
* Due to Fiber's usage of unsafe, the library may not always be compatible with the latest Go version. Fiber 2.40.0 has been tested with Go versions 1.17 to 1.20.
* Fiber is not compatible with net/http interfaces. This means you will not be able to use projects like gqlgen, go-swagger, or any others which are part of the net/http ecosystem.

### Views engines
📖 [Config](https://docs.gofiber.io/api/fiber#config)
📖 [Engines](https://github.com/gofiber/template)
📖 [Render](https://docs.gofiber.io/api/ctx#render)
Если не указано ни одного движка для views, Fiber использует [html/template](https://pkg.go.dev/html/template/).
Вы можете использовать движки [amber](https://github.com/eknkc/amber), [handlebars](https://github.com/aymerick/raymond), [mustache](https://github.com/cbroglie/mustache) или [pug](https://github.com/Joker/jade) и другие...
Ознакомьтесь с пакетом [Template](https://github.com/gofiber/template), который поддерживает множество движков для views.
```go
import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/pug"
)
func main() {
// You can setup Views engine before initiation app:
app := fiber.New(fiber.Config{
Views: pug.New("./views", ".pug"),
})
// And now, you can call template `./views/home.pug` like this:
app.Get("/", func(c *fiber.Ctx) error {
return c.Render("home", fiber.Map{
"title": "Homepage",
"year": 1999,
})
})
log.Fatal(app.Listen(":3000"))
}
```
### Группировка путей в цепочки
📖 [Group](https://docs.gofiber.io/api/app#group)
```go
func middleware(c *fiber.Ctx) error {
fmt.Println("Don't mind me!")
return c.Next()
}
func handler(c *fiber.Ctx) error {
return c.SendString(c.Path())
}
func main() {
app := fiber.New()
// Root API route
api := app.Group("/api", middleware) // /api
// API v1 routes
v1 := api.Group("/v1", middleware) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
// API v2 routes
v2 := api.Group("/v2", middleware) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
// ...
}
```
### Middleware logger
📖 [Logger](https://docs.gofiber.io/api/middleware/logger)
```go
import (
"log"

app.Use(cors.New())
// ...
log.Fatal(app.Listen(":3000"))
}
```
Проверем CORS, присвоив домен в заголовок `Origin`, отличный от `localhost`:

return c.SendString("Welcome!")
})
// Last middleware to match anything
app.Use(func(c *fiber.Ctx) error {
return c.SendStatus(404)
// => 404 "Not Found"
})
log.Fatal(app.Listen(":3000"))
}
```
### JSON Response
📖 [JSON](https://docs.gofiber.io/api/ctx#json)
```go
type User struct {
Name string `json:"name"`
Age int `json:"age"`
}

}
```

"github.com/gofiber/fiber/v2/middleware/websocket"
)
func main() {
app := fiber.New()
app.Get("/ws", websocket.New(func(c *websocket.Conn) {
for {
mt, msg, err := c.ReadMessage()
if err != nil {
log.Println("read:", err)
break
}
log.Printf("recv: %s", msg)
err = c.WriteMessage(mt, msg)
if err != nil {
log.Println("write:", err)
break
}
}
}))
log.Fatal(app.Listen(":3000"))
// => ws://localhost:3000/ws
}
```
