``jsonschema`` is an implementation of the `JSON Schema
<https://json-schema.org>`_ specification for Python.

.. code-block:: python

    >>> from jsonschema import validate

    >>> # A sample schema, like what we'd get from json.load()
    >>> schema = {
    ...     "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 --instance sample.json sample.schema

Features
--------

* Partial support for
  `Draft 2020-12 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft202012Validator>`_ and
  `Draft 2019-09 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft201909Validator>`_,
  except for ``dynamicRef`` / ``recursiveRef`` and ``$vocabulary`` (in-progress).
  Full support for
  `Draft 7 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft7Validator>`_,
  `Draft 6 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft6Validator>`_,
  `Draft 4 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft4Validator>`_
  and
  `Draft 3 <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/validators/#jsonschema.validators.Draft3Validator>`_

* `Lazy validation <https://python-jsonschema.readthedocs.io/en/latest/api/jsonschema/protocols/#jsonschema.protocols.Validator.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


Extras
======

Two extras are available when installing the package, both currently related to ``format`` validation:

    * ``format``
    * ``format-nongpl``

They can be used when installing in order to include additional dependencies, e.g.:

.. code-block:: bash

    $ pip install jsonschema'[format]'

.. start cut from PyPI

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


Community
---------

The JSON Schema specification has `a Slack
<https://json-schema.slack.com>`_, with an `invite link on its home page
<https://json-schema.org/>`_. Many folks knowledgeable on authoring
schemas can be found there.

Otherwise, asking questions on Stack Overflow is another means of
getting help if you're stuck.
