	Logger *log.Logger = log.New(os.Stdout, "", log.LstdFlags)

	// AccessLogger the logger for access. This logger
	// is used by the logging middleware.

	ErrLogger *log.Logger = log.New(os.Stderr, "", log.LstdFlags)
)

func ClearStartupHooks 

func ClearStartupHooks()

ClearStartupHooks removes all startup hooks.

func DisableMaintenance 

func DisableMaintenance()

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

func PanicStatusHandler 

func PanicStatusHandler(response *Response, request *Request)

PanicStatusHandler for the HTTP 500 error. If debugging is enabled, writes the error details to the response and print stacktrace in the console. If debugging is not enabled, writes `{"error": "Internal Server Error"}` to the response.

func RegisterStartupHook 

func RegisterStartupHook(hook func())

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

func RunTest 

func RunTest(t *testing.T, suite ITestSuite) bool

RunTest run a test suite with prior initialization of a test environment. The GOYAVE_ENV environment variable is automatically set to "test" and restored to its original value at the end of the test run. All tests are run using your project's root as working directory. This directory is determined by the presence of a "go.mod" file.

func Start 

func Start(routeRegistrer func(*Router)) error

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

import (
    "github.com/System-Glitch/goyave/v3"
    "github.com/username/projectname/route"
)

func main() {
    if err := goyave.Start(route.Register); err != nil {
        os.Exit(err.(*goyave.Error).ExitCode)
    }
}

Errors returned can be safely type-asserted to "*goyave.Error". Panics if the server is already running.

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.

Just remember that the body contains the raw data, which haven't been validated nor converted. This means that native handlers are not guaranteed to work and cannot modify the request data. Request properties, such as headers, can still be modified. Prefer implementing a Goyave handler.

This feature is a compatibility layer with the rest of the Golang web ecosystem. Prefer using Goyave handlers if possible.
