JSON formated file database

jsondb

This is a utility for managing content in a database which stores content in JSON format.

Installation

This package can be installed from PyPi by running:

pip install jsondatabase

Note, the package name and the import name are different. Import the package using import jsondb.

Usage

from jsondb.db import Database
db = Database("mydata.db")

The database has an attribute which works similar to jQuery's data attribute.

# Getting all data
db = Database("mydata.db")
print(db.data())

# Getting a stored value
db = Database("mydata.db")
print(db.data(key="user_count"))

It is important to note that a key will be created regardless of whether it exists as long as a value is provided. The database has the same functionality as a dictionary.

# Setting a value
db = Database("mydata.db")
db.data(key="user_count", value=241)

# Passing in a dictionary value
db = Database("mydata.db")
data = {
    "user_id": 234565,
    "user_name": "AwesomeUserName",
    "is_moderator": True,
}
db.data(dictionary=data)

# Deleting a value
db = Database("mydata.db")
db.delete("my_key")

The database also supports a dictionary-like syntax for retrieving, setting, and removing values.

db = Database("mydata.db")

# Retrieving a value
value = db["key"]

# Setting a value
db["key"] = value

# Removing a key
del db["key"]

# Checking if a key exists
"key" in db

Performance

If performance is an issue with large databases then the python-cjson module can be installed. jsondb will automatically detect this and use cjson instead.
