AsyncJ

AsyncJ - Python module for fast asynchronous work with JSON files

Examples

Get a dictionary from a JSON file

# Importing modules
import asyncio # To run the asynchronous main() function

from asyncj import AsyncJson # Main class used in the example

# Initialize the class with filename
asyncjson: AsyncJson = AsyncJson("test.json")


# The asynchronous main() function
async def main() -> None:
    # Getting a dictionary
    data: dict = await asyncjson.read()
    # Displaying the resulting dictionary
    print(data)


# Running the asynchronous main() function
if __name__ == "__main__": 
    asyncio.run(main())

Change dictionary in JSON file

# Importing modules
import asyncio # To run the asynchronous main() function

from asyncj import AsyncJson # Main class used in the example

from random import randint # To generate a random number

# Initialize the class with filename
asyncjson: AsyncJson = AsyncJson("test.json")


# The asynchronous main() function
async def main() -> None:
    # Getting a dictionary
    data: dict = await asyncjson.read()
    # Getting a random number
    random_number: int = randint(100, 999)
    # Setting a new random value in the dictionary for the "test" key
    data["test"] = random_number
    # Writing the modified dictionary to a JSON file
    await asyncjson.write(data)
	

# Running the asynchronous main() function
if __name__ == "__main__": 
    asyncio.run(main())

Requirements

Python version 3.8 or higher
