++h(2, "webapp") Using displaCy in a web application
+
+p
+    |  If you want to use the visualizers as part of a web application, for
+    |  example to create something like our
+    |  #[+a(DEMOS_URL + "/displacy") online demo], it's not recommended to
+    |  simply wrap and serve the displaCy renderer. Instead, you should only
+    |  rely on the server to perform spaCy's processing capabilities, and use
+    |  #[+a(gh("displacy")) displaCy.js] to render the JSON-formatted output.
+
++aside("Why not return the HTML by the server?")
+    |  It's certainly possible to just have your server return the markup.
+    |  But outputting raw, unsanitised HTML is risky and makes your app vulnerable to
+    |  #[+a("https://en.wikipedia.org/wiki/Cross-site_scripting") cross-site scripting]
+    |  (XSS). All your user needs to do is find a way to make spaCy return one
+    |  token #[code <script src="malicious-code.js"><script>].
+    |  Instead of relying on the server to render and sanitize HTML, you
+    |  can do this on the client in JavaScript. displaCy.js creates
+    |  the SVG markup as DOM nodes and will never insert raw HTML.
+
+p
+    |  The #[code parse_deps] function takes a #[code Doc] object and returns
+    |  a dictionary in a format that can be rendered by displaCy.
+
++code("Example").
+    import spacy
+    from spacy import displacy
+
+    nlp = spacy.load('en')
+
+    def displacy_service(text):
+        doc = nlp(text)
+        return displacy.parse_deps(doc)
+
+p
+    |  Using a library like #[+a("https://falconframework.org/") Falcon] or
+    |  #[+a("http://www.hug.rest/") Hug], you can easily turn the above code
+    |  into a simple REST API that receives a text and returns a JSON-formatted
+    |  parse. In your front-end, include #[+a(gh("displacy")) displacy.js] and
+    |  initialise it with the API URL and the ID or query selector of the
+    |  container to render the visualisation in, e.g. #[code '#displacy'] for
+    |  #[code <div id="displacy">].
+
++code("script.js", "javascript").
+    var displacy = new displaCy('http://localhost:8080', {
+        container: '#displacy'
+    })
+
+    function parse(text) {
+        displacy.parse(text);
+    }
+
+p
+    |  When you call #[code parse()], it will make a request to your API,
+    |  receive the JSON-formatted parse and render it in your container. To
+    |  create an interactive experience, you could trigger this function by
+    |  a button and read the text from an #[code <input>] field.
