Guards

Use f.ServerWithGuard() to add a new guard.

Note

A guard is a setup function that can inject arbitrary request handlers to handle incoming requests before they reach any of your api and page handlers.
Guards can decide which requests should pass through and which request should be rejected.

package main

import (
    "embed"
    f "github.com/razshare/frizzante"
)

//go:embed .dist/*/**
var dist embed.FS

func guard(
    withHandler func(handler func(
        request *f.Request,
        response *f.Response,
        pass func(),
    )),
) {
    withPattern("GET /")
    withHandler(func(
        request *f.Request,
        response *f.Response,
        pass func(),
    ) {
        // Guard.
        pass()
    })
}

func main() {
    // Create.
    server := f.ServerCreate()
    notifier := f.NotifierCreate()

    // Setup.
    f.ServerWithPort(server, 8080)
    f.ServerWithHostName(server, "127.0.0.1")
    f.ServerWithEmbeddedFileSystem(server, dist)
    f.ServerWithNotifier(server, notifier)

    // Guards.
    f.ServerWithGuard(server, guard)

    // Start.
    f.ServerStart(server)
}

Use pass() to let the current request pass through.

Warning

Failing to invoke pass() means the current request will be rejected.

Other details

Guards should be created under lib/guards/{name}.go, where {name} is the name of the guard.
