An Elegant Golang Web Framework

Note: This repository contains the core code of the Goyave framework. If you want to build a Goyave application, visit the Goyave Template Project repository.

Goyave is a progressive and accessible web application framework, aimed at making development easy and enjoyable. It has a philosophy of cleanliness and conciseness to make programs more elegant, easier to maintain and more focused.


Goyave has an expressive and elegant syntax. Minimalist calls and reduced redundancy are among the Goyave's core principles.


Develop faster thanks to concise and clear syntax. Low complexity functions allow for better performance.


Goyave is accessible, yet powerful, and provides many helpers and built-in functions to make your life easier and let you concentrate on the business logic.

Learning Goyave

The Goyave framework has an extensive documentation covering in-depth subjects and teaching you how to run a project using Goyave from setup to deployment.

Thank you for considering contributing to the Goyave framework! You can find the contribution guide in the documentation.

I have many ideas for the future of Goyave. I would be infinitely grateful to whoever want to support me and let me continue working on Goyave and making it better and better.

func ClearStartupHooks

func ClearStartupHooks()

    ClearStartupHooks removes all startup hooks.

    func IsReady

    func IsReady() bool

      IsReady returns true if the server has finished initializing and is ready to serve incoming requests.

      func RegisterStartupHook

      func RegisterStartupHook(hook func())

        RegisterStartupHook to execute some code once the server is ready and running.

        func Start

        func Start(routeRegistrer func(*Router))

          Start starts the web server. The routeRegistrer parameter is a function aimed at registering all your routes and middlewares.

           import (
           func main() {

          func Stop

          func Stop()

            Stop gracefully shuts down the server without interrupting any active connections.

            Make sure the program doesn't exit and waits instead for Stop to return.

            Stop does not attempt to close nor wait for hijacked connections such as WebSockets. The caller of Stop should separately notify such long-lived connections of shutdown and wait for them to close, if desired.


            type Handler

            type Handler func(*Response, *Request)

              Handler is a controller or middleware function

              type Middleware

              type Middleware func(Handler) Handler

                Middleware function generating middleware handler function.

                Request data is available to middlewares, but bear in mind that it had not been validated yet. That means that you can modify or filter data. (Trim strings for example)

                type Request

                type Request struct {
                	Rules  validation.RuleSet
                	Data   map[string]interface{}
                	Params map[string]string
                	Lang   string
                	// contains filtered or unexported fields

                  Request struct represents an http request. Contains the validated body in the Data attribute if the route was defined with a request generator function

                  func (*Request) ContentLength

                  func (r *Request) ContentLength() int64

                    ContentLength records the length of the associated content. The value -1 indicates that the length is unknown.

                    func (*Request) Cookies

                    func (r *Request) Cookies(name string) []*http.Cookie

                      Cookies returns the HTTP cookies sent with the request.

                      func (*Request) Header

                      func (r *Request) Header() http.Header

                        Header contains the request header fields either received by the server or to be sent by the client. Header names are case-insensitive.

                        If the raw request has the following header lines,

                        accept-encoding: gzip, deflate
                        Accept-Language: en-us
                        fOO: Bar
                        foo: two

                        then the header map will look like this:

                        Header = map[string][]string{
                        	"Accept-Encoding": {"gzip, deflate"},
                        	"Accept-Language": {"en-us"},
                        	"Foo": {"Bar", "two"},

                            func (r *Request) Referrer() string

                              Referrer returns the referring URL, if sent in the request.

                                        writer := httptest.NewRecorder()
                                        response := goyave.CreateTestResponse(writer)
                                        result := writer.Result()
                                        fmt.Println(result.StatusCode) // 204

It is advised to call "filesystem.FileExists()" before sending a file to avoid a panic and return a 404 error if the file doesn't exist. The given path can be relative or absolute.

                                            The "fileName" parameter defines the name the client will see. In other words, it sets the header "Content-Disposition" to "attachment; filename="${fileName}""

                                            If you want the file to be sent as an inline element ("Content-Disposition: inline"), use the "File" function instead.
