<p>A document is a single object which is stored in a collection. It can be compared to a single record in a relational database table. You get an <code>RxDocument</code> either as return on inserts, or as result-set of queries.</p>
<h2 id="insert">insert</h2>
<p>To insert a document into a collection, you have to call the collection&apos;s .insert()-function.</p>
<pre><code class="lang-js">myCollection.insert({
  name: <span class="hljs-string">&apos;foo&apos;</span>,
  lastname: <span class="hljs-string">&apos;bar&apos;</span>
});
</code></pre>
<h2 id="find">find</h2>
<p>To find documents in a collection, you have to call the collection&apos;s .find()-function. <a href="rx-query.html">See RxQuery</a>.</p>
<pre><code class="lang-js">myCollection.find().exec() <span class="hljs-comment">// &lt;- find all documents</span>

</code></pre>
<h2 id="functions">Functions</h2>
<h3 id="get">get()</h3>
<p>This will get a single field of the document. If the field is encrypted, it will be automatically decrypted before returning.</p>
<pre><code class="lang-js"><span class="hljs-keyword">var</span> name = myDocument.get(<span class="hljs-string">&apos;name&apos;</span>); <span class="hljs-comment">// returns the name</span>

<h3 id="get">get$()</h3>
<p>This function returns an observable of the given paths-value.
The current value of this path will be emitted each time the document changes.</p>
<pre><code class="lang-js"><span class="hljs-comment">// get the live-updating value of &apos;name&apos;</span>

<h3 id="proxy-get">proxy-get</h3>
<p>All properties of a <code>RxDocument</code> are assigned as getters so you can also directly access values instead of using the get()-function.</p>

<h3 id="update">update()</h3>
<p>Updates the document based on the <a href="https://docs.mongodb.com/manual/reference/operator/update-field/" target="_blank">mongo-update-syntax</a>, based on <a href="https://github.com/lgandecki/modifyjs#implemented" target="_blank">modifyjs</a>.</p>

<h3 id="atomicupdate">atomicUpdate()</h3>
<p>Updates a documents data based on a function that mutates the current data and returns the new value.
In difference to <code>update()</code>, the atomic function cannot lead to 409 write conflicts.</p>
<pre><code class="lang-js">
<span class="hljs-keyword">const</span> changeFunction = (oldData) =&gt; {
    oldData.age = oldData.age + <span class="hljs-number">1</span>;
    oldData.name = <span class="hljs-string">&apos;foooobarNew&apos;</span>;

<span class="hljs-built_in">console</span>.log(myDocument.name); <span class="hljs-comment">// &apos;foooobarNew&apos;</span>
</code></pre>
<h3 id="atomicpatch">atomicPatch()</h3>
<p>Works like <code>atomicUpdate</code> but overwrites the given attributes over the documents data.</p>
<pre><code class="lang-js"><span class="hljs-keyword">await</span> myDocument.atomicPatch({
  name: <span class="hljs-string">&apos;Steve&apos;</span>,
  age: <span class="hljs-literal">undefined</span> <span class="hljs-comment">// setting an attribute to undefined will remove it</span>
});
<span class="hljs-built_in">console</span>.log(myDocument.name); <span class="hljs-comment">// &apos;Steve&apos;</span>
</code></pre>
<h3 id="observe-">Observe $</h3>
<p>Calling this will return an <a href="http://reactivex.io/rxjs/manual/overview.html#observable" target="_blank">rxjs-Observable</a> which emits all change-Events belonging to this document.</p>
<pre><code class="lang-js"><span class="hljs-comment">// get all changeEvents</span>
myDocument.$
  .subscribe(changeEvent =&gt; <span class="hljs-built_in">console</span>.dir(changeEvent));
</code></pre>
<h3 id="remove">remove()</h3>
<p>This removes the document from the collection. Notice that this will not purge the document from the store but set <code>_deleted:true</code> like described in the <a href="https://pouchdb.com/guides/updating-deleting.html#deleting-documents" target="_blank">pouchdb-docs</a> in option 3.</p>
<pre><code class="lang-js">myDocument.remove();
</code></pre>
<h3 id="deleted">deleted$</h3>
<p>Emits a boolean value, depending on whether the RxDocument is deleted or not.</p>
<pre><code class="lang-js"><span class="hljs-keyword">let</span> lastState = <span class="hljs-literal">null</span>;
myDocument.deleted$.subscribe(state =&gt; lastState = state);

<span class="hljs-built_in">console</span>.log(lastState);
<span class="hljs-comment">// false</span>

<span class="hljs-keyword">await</span> myDocument.remove();

<span class="hljs-built_in">console</span>.log(lastState);
<span class="hljs-comment">// true</span>
</code></pre>
<h3 id="get-deleted">get deleted</h3>
<p>A getter to get the current value of <code>deleted$</code>.</p>
<pre><code class="lang-js"><span class="hljs-built_in">console</span>.log(myDocument.deleted);
<span class="hljs-comment">// false</span>

<span class="hljs-keyword">await</span> myDocument.remove();

<span class="hljs-built_in">console</span>.log(myDocument.deleted);
<span class="hljs-comment">// true</span>
</code></pre>
<h3 id="tojson">toJSON()</h3>
<p>Returns the document&apos;s data as plain json object. This will return an <strong>immutable</strong> object. To get something that can be modified, use <code>toMutableJSON()</code> instead.</p>
<pre><code class="lang-js"><span class="hljs-keyword">const</span> json = myDocument.toJSON();
<span class="hljs-built_in">console</span>.dir(json);
<span class="hljs-comment">/* { passportId: &apos;h1rg9ugdd30o&apos;,
  firstName: &apos;Carolina&apos;,
  lastName: &apos;Gibson&apos;,
  age: 33 ...
*/</span>
</code></pre>
<p>You can also set <code>withMetaFields: true</code> to get additional meta fields like the revision, attachments or the deleted flag.</p>
<pre><code class="lang-js"><span class="hljs-keyword">const</span> json = myDocument.toJSON(<span class="hljs-literal">true</span>);
<span class="hljs-built_in">console</span>.dir(json);
<span class="hljs-comment">/* { passportId: &apos;h1rg9ugdd30o&apos;,

  lastName: &apos;Gibson&apos;,
  _deleted: false,
  _attachments: { ... },
  _rev: &apos;1-aklsdjfhaklsdjhf...&apos;
*/</span>
</code></pre>
<h3 id="tomutablejson">toMutableJSON()</h3>
<p>Same as <code>toJSON()</code> but returns a deep cloned object that can be mutated afterwards.
Remember that deep cloning is performance expensive and should only be done when necessary.</p>
<pre><code class="lang-js"><span class="hljs-keyword">const</span> json = myDocument.toMutableJSON();
json.firstName = <span class="hljs-string">&apos;Alice&apos;</span>; <span class="hljs-comment">// The returned document can be mutated</span>
</code></pre>
<h2 id="notice-all-methods-of-rxdocument-are-bound-to-the-instance">NOTICE: All methods of RxDocument are bound to the instance</h2>
<p>When you get a method from a <code>RxDocument</code>, the method is automatically bound to the documents instance. This means you do not have to use things like <code>myMethod.bind(myDocument)</code> like you would do in jsx.</p>
<h3 id="isrxdocument">isRxDocument</h3>
<p>Returns true if the given object is an instance of RxDocument. Returns false if not.</p>
<pre><code class="lang-js"><span class="hljs-keyword">const</span> is = isRxDocument(myObj);
</code></pre>
