Routerling

A new born baby router on it's way to being a web development platform. Routerling is a router multiplexer built with 1 goal in mind.

• Make it stupid simple to build high performance web applications

How?

Following the unix philosophy of be the master of one thing and one thing only - Routerling has only ONE API you need to learn - Router. The API is also deliberately made consistent across the 3 different supported languages [Golang, Python, Typescript/JavaScript]. See Similarities

 

Python

from routerling import Context, HttpRequest, ResponseWriter, Router
from logging import log

def get_customer_orders(r: HttpRequest, w: ReponseWriter, s: State):
    w.headers = "go-go-gadget", ""
    w.body = '{customer: {customer_id}, orders: []}'.format(r.params.get('id'))

def change_headers(r: HttpRequest, w: ResponseWriter, s: State):
    w.headers = "go-go-gadget", "i was changed after..."

def create_customer(r: HttpRequest, w: ResponseWriter, s: State):
    print(r.body)
    w.status = 201
    w.body = '{id: 13}'


# register functions to routes
router.BEFORE('/*', lambda req, res, state: print('will run before all routes are handled'))
router.AFTER('/v1/customers/*', change_headers)
router.GET('/v1/customers/:id/orders', get_customer_orders)
router.GET('/v1/customers/:id', lambda req, res, state: log(2, state.abcxyz_variable))
router.POST('/v1/customers', create_customer)

Request Object

• request.body

  Body/payload of request if it exists. You can use any XML, JSON, CSV etc. library you prefer to parse r.body as you like.

  # r.body: str
  body: str = r.body
  

• request.headers header = r.headers.get('header-name')

  All headers sent with the request.

  # r.headers: dict
  header = r.headers.get('content-type')
  

• request.params param = r.params.get('param-name')

  Dictionary containing parts of the url that matched your route parameters i.e. /customers/:id/orders will return {'id': 45} for url /customers/45/orders.

  body: str = r.body
  

 

Response Object

• response.abort

  Signals to routerling that you want to abort a request and ignore all GET, POST, PUT etc. handlers including all AFTER or BEFORE hooks from executing. The payload given to abort is used as the response body. Only calling w.abort() will not end function execution. You have to explicitly return from the request handler after using w.abort().

  w.abort('This is the body/payload i want to abort with')
  return
  

• response.body

  Used to set payload/body to be sent back to the client. Returning data from a handler function does not do anything and is not used by routerling. To send something back to the client use w.body.

  w.body = b'my body'
  

• response.headers

  Used to set headers to be sent back to the client.

  w.headers = "Content-Type", "application/json"
  w.headers = ["Authorization", "Bearer myToken"]
