<h1>Custom Web pages w/o JSON</h1>
<h2 id="suppress-increase-in-memory-consumption">Suppress increase in memory consumption<a class="headerlink" href="#suppress-increase-in-memory-consumption" title="Permanent link">&para;</a></h2>
<p>Custom Web page processing consumes a lot of memory. AutoConnect will take a whole string of the JSON document for the custom Web pages into memory. The required buffer size for the JSON document of example sketch <em>mqttRSSI</em> reaches approximately 3000 bytes. And actually, it needs twice the heap area. Especially this constraint will be a problem with the ESP8266 which has a heap size poor.</p>
<p>AutoConnect can handle custom Web pages without using JSON. In that case, since the ArduinoJson library will not be bound, the sketch size will also be reduced.</p>
<h2 id="writing-the-custom-web-pages-without-json">Writing the custom Web pages without JSON<a class="headerlink" href="#writing-the-custom-web-pages-without-json" title="Permanent link">&para;</a></h2>
<p>To handle a custom Web page without using JSON, follow the steps below.</p>
<ol>
<li>Create or define <a href="apiaux.html">AutoConnectAux</a> for each page.</li>
<li>Create or define <a href="acelements.html">AutoConnectElement(s)</a>.</li>
<li>Add <a href="acelements.html">AutoConnectElement(s)</a> to AutoConnectAux.</li>
<li>Create more AutoConnectAux containing <a href="acelements.html">AutoConnectElement(s)</a>, if necessary.</li>
<li>Register the request handlers for the custom Web pages.</li>
<li><a href="api.html#join">Join</a> prepared AutoConnectAux(s) to AutoConnect.</li>
<li>Invoke <a href="api.html#begin">AutoConnect::begin()</a>.</li>
</ol>
<p>In addition to the above procedure, to completely cut off for binding with the ArduinoJson library, turn off the ArduinoJson use indicator which is declared by the <a href="api.html#defined-macros">AutoConnect definitions</a>. Its declaration is in <strong>AutoConnectDefs.h</strong> file.<sup id="fnref:1"><a class="footnote-ref" href="#fn:1" rel="footnote">1</a></sup></p>

<div class="admonition caution">
<p class="admonition-title">JSON processing will be disabled</p>
<p>Commenting out the <strong>AUTOCONNECT_USE_JSON</strong> macro invalidates all functions related to JSON processing. If the sketch is using the JSON function, it will result in a compile error.</p>
