Examples

here you can find examples repository

  await router.openGates();
}

Core Parts

Handler

type of functions that

• return Future or void
• takes tow arguments
  • Request req
  • Response res

a handler will be triggered when a match happened between the incoming request and the endpoint registered path

Request

wrapper class around dart HttpRequest will contains wrappers around the dart:io HttpRequest class and the httpRequest itself

Response

wrapper class around dart:io HttpResponse will have functions ease the process of responding to the incoming requests like

• res.json(data?) will convert the given data to JSON and sent it back to the user
• res.file(path)
• res.notFound(data?) => 404
• res.internalServerError(data?) => 500
• res.accepted(data?) => 200
• res.created(data?) => 201
• and so on....

if you respond to the request you will be ending the request life cycle this means guard still will be working but they can not modify the response any more

PalaceRouter

• register routes and the handler for each route
• register guards
• open the server
• close the server

Middleware aka Guard 💂‍♂️

type of functions that

• return Future or void

• takes three arguments

  • Request req
  • Response res
  • Function next

guards considered as extra layer before the Handlers layers

a guard can be registered for specific route or as global guard for any kind of requests

a guard can response to incoming requests since the have access to the instance of the incoming request

a guard can preform any kind of logic before or after the handler be triggered
