Fiber: 🚀 Add Routing Middleware

[fauzan121002]

Add Routing Middleware

package router

import "github.com/gofiber/fiber"

func Routes() *fiber.App{
    app := fiber.New()
    api := app.Group("/api")

    app.Use(Web)

    v1 := api.Group("/v1", func(c *fiber.Ctx){
        c.JSON(fiber.Map{
          "message":"v1",
        })

        c.Next()
    }) 

    v1.Use(Api)

    return app
}

so we can easily and cleaner to do routing.

Like this :

If I'm correct, you want to be able to register/mount another fiber instance?
This is currently not possible, but this is something we might implement in v2.x

package main

import (
    "log"

    "github.com/gofiber/fiber"
)

var handler = func(c *fiber.Ctx) {}

func v1() fiber.Router {
    app := fiber.New()
    app.Get("/john", handler)
    return app
}

func v2() fiber.Router {
    app := fiber.New()
    app.Get("/john", handler)
    app.Post("/doe", handler)
    return app
}

func main() {
    app := fiber.New()

    app.Use("/v1", v1()) // GET  /v1/john

    app.Use("/v2", v2()) // GET  /v2/john
                 // POST /v2/doe

    log.Fatal(app.Listen(":3000"))
}

  log.Fatal(app.Listen(":3000"))
}

yes, that will be good to. can't wait for it.

I also want this to be in fiber 😍.

Just a suggestion, instead of calling it fiber.New() could it be called fiber.Router(), just like express.

This is not possible because Router is a reserved interface for *App and *Group

Yeah, I forgot about that.

Maybe something else can be used. IMO calling fiber.New() for a router, looks like spawning a new fiber app. Thoughts?

[Fenny]

Calling fiber.New() will create a new instance that can be used as a router.
We should document the behavior if a Group or App is registered using Use

// Use registers a middleware handler or Router. that will match requests
// that contain the provided prefix ( which is optional and defaults to "/" ).
//
// This method will match all HTTP verbs: GET, POST, PUT, HEAD etc...

@fauzan121002, unfortunately, this idea did not make it with the v2 release. We are working on to have a similar functionality ready for v2.1.x, I will keep this issue open for development updates.

@fauzan121002, a quick update regarding this issue.

https://github.com/gofiber/fiber/pull/830 introduces the new Mount method to embed another Fiber instance to a prefix path.

    // some micro service
    micro := fiber.New()
    micro.Get("/doe", func(c *fiberCtx) error {
        return c.SendStatus(StatusOK)
    })

    // main.go
    app := fiber.New()
    app.Mount("/john", micro)

    // GET /john/doe -> 200 OK
