Slide, a Go web framework for Building API(s)

tags: Go Express

Slide is one of the fastest frameworks, built on top of fasthttp. People coming form express will feel at home.

Motivation

While playing around with the Go’s net/http, one thing that we missed most was the lack of middleware support and the problems it solves. After a little reading, we decided to write our own web framework which would solve the issues like middleware support with next, handle a wide range of files, Upload, Download, etc.

:bulb: Note: We are still in experimental stage, would love to hear feedback.

Installation

go get -u github.com/go-slide/slide

:rocket: Example

For more API information check Docs

package main

import (
	"log"
	"github.com/go-slide/slide"
	"github.com/go-playground/validator/v10"
)

func main() {
    validate := validator.New()
    config := slide.Config{
	Validator: validate,
    }
    app := slide.InitServer(&config)
    app.Get("/", func(ctx *slide.Ctx) error {
        return ctx.Send(http.StatusOK, "Hello, World")
    })
    log.Fatal(app.Listen("localhost:4321"))
}

Routing

Slide supports multilevel routing.

app := slide.InitServer(&config)

app.Get("/", func(ctx *slide.Ctx) error {
    return ctx.Send(http.StatusOK, "Hello, World")
})

// Grouping your route
auth := app.Group("/auth")
auth.Get("/login", func(ctx *slide.Ctx) error {
    return ctx.Send(http.StatusOK, "Hello, World")
})

Middleware

Slide supports wide range of middlewares.

1. Application Level
2. Group Level
3. Route Level

app := slide.InitServer(&config)

## Application level
app.Use(func(ctx *slide.Ctx) error {
    fmt.Println("this will run for all URL(s)")
    return ctx.Next()
})

//Group Level
auth := app.Group("/auth")
auth.Use(func(ctx *slide.Ctx) error {
    fmt.Println("this will run for all /auth URL(s)")
    return ctx.Next()
})
auth.Get("/login", func(ctx *slide.Ctx) error {
    return ctx.Send(http.StatusOK, "Hello, World")
})

// Route level, works in Right -> Left or Bottom to Top
app.Get("/routermiddleware", func(ctx *slide.Ctx) error {
    return ctx.Send(http.StatusOK, "hola!")
}, func(ctx *slide.Ctx) error {
    fmt.Println("this prints second", ctx.RequestCtx.UserValue("lol"))
    return ctx.Next()
}, func(ctx *slide.Ctx) error {
    fmt.Println("this prints first")
    return ctx.Next()
})
