_Introduction
TinyDB is a lightweight document oriented database optimized for your happiness :) It's written in pure Python and has no external dependencies. The target are small apps that would be blown away by a SQL-DB or an external database server.
TinyDB is:
tiny: The current source code has 1800 lines of code (with about 40% documentation) and 1600 lines tests.
document oriented: Like MongoDB_, you can store any document
(represented as dict
) in TinyDB.
optimized for your happiness: TinyDB is designed to be simple and fun to use by providing a simple and clean API.
written in pure Python: TinyDB neither needs an external server (as
e.g. PyMongo <https://pymongo.readthedocs.io/en/stable/>
_) nor any dependencies
from PyPI.
works on Python 3.8+ and PyPy3: TinyDB works on all modern versions of Python and PyPy.
powerfully extensible: You can easily extend TinyDB by writing new storages or modify the behaviour of storages with Middlewares.
100% test coverage: No explanation needed.
To dive straight into all the details, head over to the TinyDB docs <https://tinydb.readthedocs.io/>
. You can also discuss everything related
to TinyDB like general development, extensions or showcase your TinyDB-based
projects on the discussion forum <http://forum.m-siemens.de/.>
.
Supported Python Versions
TinyDB has been tested with Python 3.8 - 3.13 and PyPy3.

Example Code
.. code-block:: python
>>> from tinydb import TinyDB, Query
>>> db = TinyDB('/path/to/db.json')
>>> db.insert({'int': 1, 'char': 'a'})
>>> db.insert({'int': 1, 'char': 'b'})
.. code-block:: python
>>> User = Query()
>>> # Search for a field value
>>> db.search(User.name == 'John')
[{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}]
>>> # Combine two queries with logical and
>>> db.search((User.name == 'John') & (User.age <= 30))
[{'name': 'John', 'age': 22}]
>>> # Combine two queries with logical or
>>> db.search((User.name == 'John') | (User.name == 'Bob'))
[{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}, {'name': 'Bob', 'age': 42}]
>>> # Negate a query with logical not
>>> db.search(~(User.name == 'John'))
[{'name': 'Megan', 'age': 27}, {'name': 'Bob', 'age': 42}]
>>> # Apply transformation to field with `map`
>>> db.search((User.age.map(lambda x: x + x) == 44))
>>> [{'name': 'John', 'age': 22}]
>>> # More possible comparisons: != < > <= >=
>>> # More possible checks: where(...).matches(regex), where(...).test(your_test_func)
.. code-block:: python
>>> table = db.table('name')
>>> table.insert({'value': True})
>>> table.all()
[{'value': True}]
.. code-block:: python
>>> from tinydb.storages import JSONStorage
>>> from tinydb.middlewares import CachingMiddleware
>>> db = TinyDB('/path/to/db.json', storage=CachingMiddleware(JSONStorage))
