"type" : "object", ... "properties" : { ... "price" : {"type" : "number"}, ... "name" : {"type" : "string"}, ... }, ... } >>> # If no exception is raised by validate(), the instance is valid. >>> validate(instance={"name" : "Eggs", "price" : 34.99}, schema=schema) >>> validate( ... instance={"name" : "Eggs", "price" : "Invalid"}, schema=schema, ... ) # doctest: +IGNORE_EXCEPTION_DETAIL Traceback (most recent call last): ... ValidationError: 'Invalid' is not of type 'number' It can also be used from console: .. code-block:: bash $ jsonschema -i sample.json sample.schema Features -------- * Full support for `Draft 7 <https://python-jsonschema.readthedocs.io/en/latest/validate/#jsonschema.Draft7Validator>`_, `Draft 6 <https://python-jsonschema.readthedocs.io/en/latest/validate/#jsonschema.Draft6Validator>`_, `Draft 4 <https://python-jsonschema.readthedocs.io/en/latest/validate/#jsonschema.Draft4Validator>`_ and `Draft 3 <https://python-jsonschema.readthedocs.io/en/latest/validate/#jsonschema.Draft3Validator>`_ * `Lazy validation <https://python-jsonschema.readthedocs.io/en/latest/validate/#jsonschema.IValidator.iter_errors>`_ that can iteratively report *all* validation errors. * `Programmatic querying <https://python-jsonschema.readthedocs.io/en/latest/errors/>`_ of which properties or items failed validation. Installation ------------ ``jsonschema`` is available on `PyPI <https://pypi.org/project/jsonschema/>`_. You can install using `pip <https://pip.pypa.io/en/stable/>`_: .. code-block:: bash $ pip install jsonschema Demo ---- Try ``jsonschema`` interactively in this online demo: .. image:: https://user-images.githubusercontent.com/1155573/56745335-8b158a00-6750-11e9-8776-83fa675939c4.png :target: https://notebooks.ai/demo/gh/Julian/jsonschema :alt: Open Live Demo Online demo Notebook will look similar to this: .. image:: https://user-images.githubusercontent.com/1155573/56820861-5c1c1880-6823-11e9-802a-ce01c5ec574f.gif :alt: Open Live Demo :width: 480 px Release Notes ------------- v3.1 brings support for ECMA 262 dialect regular expressions throughout schemas, as recommended by the specification. Big thanks to @Zac-HD for authoring support in a new `js-regex <https://pypi.org/project/js-regex/>`_ library. Running the Test Suite ---------------------- If you have ``tox`` installed (perhaps via ``pip install tox`` or your package manager), running ``tox`` in the directory of your source checkout will run ``jsonschema``'s test suite on all of the versions of Python ``jsonschema`` supports. If you don't have all of the versions that ``jsonschema`` is tested under, you'll likely want to run using ``tox``'s ``--skip-missing-interpreters`` option. Of course you're also free to just run the tests on a single version with your favorite test runner. The tests live in the ``jsonschema.tests`` package. Benchmarks ---------- ``jsonschema``'s benchmarks make use of `pyperf <https://pyperf.readthedocs.io>`_. Running them can be done via ``tox -e perf``, or by invoking the ``pyperf`` commands externally (after ensuring that both it and ``jsonschema`` itself are installed):: $ python -m pyperf jsonschema/benchmarks/test_suite.py --hist --output results.json To compare to a previous run, use:: $ python -m pyperf compare_to --table reference.json results.json See the ``pyperf`` documentation for more details. Community --------- There's a `mailing list <https://groups.google.com/forum/#!forum/jsonschema>`_ for this implementation on Google Groups. Please join, and feel free to send questions there. Contributing ------------ I'm Julian Berman. ``jsonschema`` is on `GitHub <https://github.com/Julian/jsonschema>`_. Get in touch, via GitHub or otherwise, if you've got something to contribute, it'd be most welcome! You can also generally find me on Freenode (nick: ``tos9``) in various channels, including ``#python``. If you feel overwhelmingly grateful, you can also woo me with beer money via Google Pay with the email in my GitHub profile. And for companies who appreciate ``jsonschema`` and its continued support and growth, ``jsonschema`` is also now supportable via `TideLift <https://tidelift.com/subscription/pkg/pypi-jsonschema?utm_source=pypi-j sonschema&utm_medium=referral&utm_campaign=readme>`_.
