A gevent based hi-performance python server, suited best for websockets and api servers. (Additional aws utitlies for Dynamo and sqs inbuilt).

High performance gevent based python3 server.

Very simplistic API, Best suited for API servers, websocket, realtime games, chat. Generates autoapi docs and packed with a bunch of useful utilities.

schema generator and validation in 200 lines.

Schema generator and validation (inplace)

class Test2(Object):
	a: Array(int)
	b: Int
	c: Str(format="datetime")
	d: Optional[Str(format="datetimez")]
	e: Str(maxlen=9)
	

	def __init__(self):
		self.a = ["string"]
		self.b = 100
		self.c = "2021-10-08 14:39:56.621851"
		self.e = "somerandomstring"


test2_schema, test2_validator = schema(Test2)


print(json.dumps(test2_schema, indent=4))


obj = Test2()
print(obj.__dict__)

test2_validator(obj)
print(obj.__dict)

Let's build few cross platform applications

Example 1: (PasteBin)

• Create a paste, with some text, restrict to users, password, file upload

import blaster # should be first line, does the gevent monkey patch
from blaster.server import route
from blaster.schema import Object

class CreatePasteRequest(Object):
	title: Str(maxlen=100)
	content: Str
	user_ids: Optional[Array(str)]
	password: Optional[Str(maxlen=100)]
	upload: Optional[Str(format=binary)] #this will actually be a dict {"data": .., "headers": .., "attrs": ...}



class PasteResponse(Object):
	title: Str(maxlen=100)
	content: Str
	created_by: Str
	password: Optional[Str]
	


@route("/create", methods=POST)
def create(req: CreatePasteRequest) -> PasteResponse:   #give the argument a type and it's available to you, check all available types
	if(req.upload):
		pass
