json-storage-manager
json-storage-manager is a Python Package that simply manages the JSON files with the stored data of products and orders for a demo store API.
Installation
pip install json-storage-manager
atomic
Usage
atomic is basically used as a custom context manager for writing JSON files without downtime for the original file.
It simply loads the JSON file into memory and opens a temporary file using the tempfile Python Package, finally once the operation is finished it performs an os.replace() to replace the original file (which is an atomic operation on Linux systems).
from json_storage_manager import atomic
with atomic.atomic_write(str(json_file)) as temp_file:
with open(str(json_file)) as products_file:
# get the JSON data into memory
products_data = json.load(products_file)
# now process the JSON data
products_data.append(
{'uuid': "2299d69e-deba-11e8-bded-680715cce955",
'special_price': 111.0,
'name': "Test Product"
})
json.dump(products_data, temp_file)
