<h2 id="interactive-api-documentation"><a class="toclink" href="#interactive-api-documentation">Interactive API documentation</a></h2>
<p>REST framework's new API documentation supports a number of features:</p>
<ul>
<li>Live API interaction.</li>
<li>Support for various authentication schemes.</li>
<li>Code snippets for the Python, JavaScript, and Command Line clients.</li>
</ul>
<p>The <code>coreapi</code> library is required as a dependancy for the API docs. Make sure
to install the latest version (2.3.0 or above). The <code>pygments</code> and <code>markdown</code>
libraries are optional but recommended.</p>
<p>To install the API documentation, you'll need to include it in your projects URLconf:</p>
<pre><code>from rest_framework.documentation import include_docs_urls
API_TITLE = 'API title'
API_DESCRIPTION = '...'
urlpatterns = [
...
url(r'^docs/', include_docs_urls(title=API_TITLE, description=API_DESCRIPTION))
]
</code></pre>
<p>Once installed you should see something a little like this:</p>
<p><img alt="API Documentation" src="../../img/api-docs.png" /></p>
<p>We'll likely be making further refinements to the API documentation over the
coming weeks. Keep in mind that this is a new feature, and please do give
us feedback if you run into any issues or limitations.</p>
<p>For more information on documenting your API endpoints see the <a href="../documenting-your-api/">"Documenting your API"</a> section.</p>
<hr />
<h2 id="javascript-client-library"><a class="toclink" href="#javascript-client-library">JavaScript client library</a></h2>
<p>The JavaScript client library allows you to load an API schema, and then interact
with that API at an application layer interface, rather than constructing fetch
requests explicitly.</p>
<p>Here's a brief example that demonstrates:</p>
<ul>
<li>Loading the client library and schema.</li>
<li>Instantiating an authenticated client.</li>
<li>Making an API request using the client.</li>
</ul>
<p><strong>index.html</strong></p>
<pre><code>&lt;html&gt;
&lt;head&gt;
&lt;script src="/static/rest_framework/js/coreapi-0.1.0.js"&gt;&lt;/script&gt;
&lt;script src="/docs/schema.js' %}"&gt;&lt;/script&gt;
&lt;script&gt;
const coreapi = window.coreapi
const schema = window.schema
// Instantiate a client...
let auth = coreapi.auth.TokenAuthentication({scheme: 'JWT', token: 'xxx'})
let client = coreapi.Client({auth: auth})
// Make an API request...
client.action(schema, ['projects', 'list']).then(function(result) {
alert(result)
})
&lt;/script&gt;
&lt;/head&gt;
&lt;/html&gt;
</code></pre>
<p>The JavaScript client library supports various authentication schemes, and can be
used by your project itself, or as an external client interacting with your API.</p>
<p>The client is not limited to usage with REST framework APIs, although it does
currently only support loading CoreJSON API schemas. Support for Swagger and
other API schemas is planned.</p>
<p>For more details see the <a href="../api-clients/#javascript-client-library">JavaScript client library documentation</a>.</p>
<h2 id="authentication-classes-for-the-python-client-library"><a class="toclink" href="#authentication-classes-for-the-python-client-library">Authentication classes for the Python client library</a></h2>
<p>Previous authentication support in the Python client library was limited to
allowing users to provide explicit header values.</p>
<p>We now have better support for handling the details of authentication, with
the introduction of the <code>BasicAuthentication</code>, <code>TokenAuthentication</code>, and
<code>SessionAuthentication</code> schemes.</p>
<p>You can include the authentication scheme when instantiating a new client.</p>
<pre><code>auth = coreapi.auth.TokenAuthentication(scheme='JWT', token='xxx-xxx-xxx')
client = coreapi.Client(auth=auth)
</code></pre>
<p>For more information see the <a href="../api-clients/#python-client-library">Python client library documentation</a>.</p>

<h2 id="deprecations"><a class="toclink" href="#deprecations">Deprecations</a></h2>
<h3 id="updating-coreapi"><a class="toclink" href="#updating-coreapi">Updating <code>coreapi</code></a></h3>
<p>If you're using REST framework's schema generation, or want to use the API docs,
then you'll need to update to the latest version of coreapi. (2.3.0)</p>
<h3 id="generating-schemas-from-router"><a class="toclink" href="#generating-schemas-from-router">Generating schemas from Router</a></h3>
<p>The 3.5 "pending deprecation" of router arguments for generating a schema view, such as <code>schema_title</code>, <code>schema_url</code> and <code>schema_renderers</code>, have now been escalated to a
"deprecated" warning.</p>
<p>Instead of using <code>DefaultRouter(schema_title='Example API')</code>, you should use the <code>get_schema_view()</code> function, and include the view explicitly in your URL conf.</p>
<h3 id="djangofilterbackend"><a class="toclink" href="#djangofilterbackend">DjangoFilterBackend</a></h3>
<p>The 3.5 "pending deprecation" warning of the built-in <code>DjangoFilterBackend</code> has now
been escalated to a "deprecated" warning.</p>
<p>You should change your imports and REST framework filter settings as follows:</p>
<ul>
<li><code>rest_framework.filters.DjangoFilterBackend</code> becomes <code>django_filters.rest_framework.DjangoFilterBackend</code>.</li>
<li><code>rest_framework.filters.FilterSet</code> becomes <code>django_filters.rest_framework.FilterSet</code>.</li>
</ul>
<hr />
<h2 id="whats-next"><a class="toclink" href="#whats-next">What's next</a></h2>
<p>There are likely to be a number of refinements to the API documentation and
JavaScript client library over the coming weeks, which could include some of the following:</p>
<ul>
<li>Support for private API docs, requiring login.</li>
<li>File upload and download support in the JavaScript client &amp; API docs.</li>
<li>Comprehensive documentation for the JavaScript client library.</li>
<li>Automatically including authentication details in the API doc code snippets.</li>
<li>Adding authentication support in the command line client.</li>
<li>Support for loading Swagger and other schemas in the JavaScript client.</li>
<li>Improved support for documenting parameter schemas and response schemas.</li>
<li>Refining the API documentation interaction modal.</li>
</ul>
<p>Once work on those refinements is complete, we'll be starting feature work
on realtime support, for the 3.7 release.</p>
