asyncio-tcp-messages

A library for developing applications with a message-based protocol on top of TCP based on asyncio.Opens the possibility of adding controllers that are responsible for specific commands, the ability to define and validate command arguments.

• First, you need to create an instance of the App class

  import asyncio
  from asyncio_tcp_messages import App
  
  app = App()
  
  #Your code
  
  if __name__ == '__main__':
      asyncio.run(app.run())
  
  

• Here are some usage examples. You can use pydantic BaseModel subclasses for data validation.

  import asyncio
  from asyncio_tcp_messages import App
  import pydantic
  
  app = App()
  
  
  class Person(pydantic.BaseModel):
      name: str = pydantic.Field(..., min_length=2, max_length=250, description="The person's name must be at least 2 "
                                                                                "and at most 250 characters")
      age: int = pydantic.Field(..., ge=0, lt=200, description="The person's age must be greater or equal to zero "
                                                               "and lesser than 250")
      funs: list[str] = pydantic.Field(default_factory=list, title="The activities person likes to do")
      salary: int = pydantic.Field(None, gt=0, description="The person's salary must be greater than zero")
  
      def __str__(self) -> str:
          return f'{self.name} is {self.age} years old with {self.salary}$ salary and favourite activities: {self.funs}'
  
  
  @app.command(name='sum')
  async def custom_sum(user_id: int, arg1: int, arg2: int) -> str:
      return str(arg1 + arg2)
  
  
  @app.command()
  async def add_person(user_id: int, person: Person):
      people.append(person)
  
  
  @app.command()
  async def get_person(user_id: int, name: str) -> str:
      return '\n'.join(str(person) for person in people if person.name == name)
  
  
  if __name__ == '__main__':
      asyncio.run(app.run())
