JSONLite is a lightweight, local JSON database for simple data storage.
pip install jsonlite
{
"data": [
{ "_id": 1,
"name": "Alice",
"age": 30
},
{ "_id": 2,
"name": "Bob",
"age": 25
},
{ "_id": 3,
"name": "Charlie",
"age": 20
}
]
}
You can use JSONlite directly to perform CRUD operations.
>>> from jsonlite import JSONlite
>>> # Initialize the database
>>> db = JSONlite('mydatabase.json')
>>> # Inserting one document
>>> result = db.insert_one({"name": "John Doe", "age": 30})
>>> result.inserted_id
1
>>> # Inserting multiple documents
>>> result = db.insert_many([
... {"name": "Jane Doe", "age": 25},
... {"name": "Alice", "age": 28}
... ])
>>> result.inserted_ids
[2, 3]
>>> # Finding one document
>>> document = db.find_one({"name": "John Doe"})
>>> document
{'_id': 1, 'name': 'John Doe', 'age': 30}
>>> # Finding multiple documents
>>> documents = db.find({"age": {"$gte": 25}})
>>> documents
[
{'_id': 1, 'name': 'John Doe', 'age': 30},
{'_id': 2, 'name': 'Jane Doe', 'age': 25},
{'_id': 3, 'name': 'Alice', 'age': 28}
]
>>> # Updating one document
>>> result = db.update_one({"name": "John Doe"}, {"$set": {"age": 31}})
>>> result.matched_count, result.modified_count
(1, 1)
>>> # Updating multiple documents
>>> result = db.update_many({"age": {"$gte": 25}}, {"$set": {"status": "active"}})
>>> result.matched_count, result.modified_count
(3, 3)
>>> # Deleting one document
>>> result = db.delete_one({"name": "John Doe"})
>>> result.deleted_count
1
>>> # Deleting multiple documents
>>> result = db.delete_many({"age": {"$lt": 30}})
>>> result.deleted_count
2
Alternatively, you can patch pymongo to use JSONlite and interact with JSON files as if you were using MongoDB. This allows you to use the familiar pymongo API with JSON data.
>>> from jsonlite import pymongo_patch
>>> pymongo_patch()
>>> from pymongo import MongoClient
>>> client = MongoClient('jsonlite://database')
>>> db = client.test_database
>>> collection = db.test_collection
>>> insert_result = collection.insert_one({"name": "Alice", "age": 30})
>>> # Just like using pymongo
>>> collection.drop()
