asyncio-tcp-messages 0.1.4

A library for developing applications with a message-based protocol on top of TCP based on asyncio.

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.

1. 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())
   
   

2. 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())
