<h1>
UIbuilder + Vue.js + bootstrap-vue for Node-RED
</h1>
<p>
This is a uibuilder example using <a href="https://vuejs.org/">Vue.js</a> as a front-end library.
See the
<a
href="https://github.com/TotallyInformation/node-red-contrib-uibuilder">node-red-contrib-uibuilder</a>
README for details on how to use UIbuilder.
</p>

<h2>Simple input using Vue</h2>
<b-form class="border p-3 m-2">
<p>
You can very simply create a form using Vue & bootstrap-vue.
The form sends data back to Node-RED.
Look at the <code>increment</code> method in <code>index.js</code> to see how easy this is.
</p>
<p>
<b-form-input v-model="inputText" type="text" placeholder="Enter some text to send to Node-RED"></b-form-input><br>
<b-form-checkbox v-model="inputChkBox">
To tick or not to tick? That is the question
</b-form-checkbox><br>
<b-button id="btn_increment" pill variant="primary" v-on:click="increment">Increment</b-button>
&nbsp;&nbsp;Click Counter: <b>{{counterBtn}}</b>.
<p>Click on the button to increment the counter. It sends the data dynamically back to Node-RED as well.</p>
</p>
</b-form>

<h2>Dynamic Data</h2>
<p>Uses Vue to dynamically update in response to messages from Node-RED.</p>
<p>
Check out the <code>mounted</code> function in <code>index.js</code> to See
how easy it is to update Vue data from Node-RED.
</p>

<b-card class="mt-3" header="Status" border-variant="info" header-bg-variant="info" header-text-variant="white" align="center" >
<p class="float-left">Socket.io Connection Status: <b>{{socketConnectedState}}</b></p>
<p class="float-right">Time offset between browser and server: <b>{{serverTimeOffset}}</b> hours</p>
</b-card>

<b-card class="mt-3" header="Normal Messages" border-variant="primary" header-bg-variant="primary" header-text-variant="white" align="left" >
<p>
Messages: Received=<b>{{msgsReceived}}</b>, Sent=<b>{{msgsSent}}</b>
</p>
<pre v-html="hLastRcvd" class="syntax-highlight"></pre>
<pre v-html="hLastSent" class="syntax-highlight"></pre>
<p slot="footer" class="mb-0">
The received message is from the input to the uibuilder node.
The send message will appear out of port #1 of the node.
</p>
</b-card>

<b-card class="mt-3" header="Control Messages" border-variant="secondary" header-bg-variant="secondary" header-text-variant="white" align="left" >
<p>
Control Messages: Received=<b>{{msgsControl}}</b>, Sent=<b>{{msgsCtrlSent}}</b>
</p>
<pre v-html="hLastCtrlRcvd" class="syntax-highlight"></pre>
<pre v-html="hLastCtrlSent" class="syntax-highlight"></pre>
<p slot="footer" class="mb-0">
Control messages always appear out of port #2 of the uibuilder node
whether they are from the server or the client. The <code>from</code> property
of the message tells you where it came from.
</p>
</b-card>
