|
||
<p>The <strong>If-Else</strong> component is a conditional router that routes messages by comparing two strings.
|
||
It evaluates a condition by comparing two text inputs using the specified operator, and then routes the message to <code>true_result</code> or <code>false_result</code> depending on the evaluation.</p>
|
||
<p>The operator looks for single strings in the input (<code>input_text</code>) based on an operator and match text (<code>match_text</code>), but it can also search for multiple words by matching a regex.
|
||
Available operators include:</p>
|
||
<ul>
|
||
<li class=""><strong>equals</strong>: Exact match comparison</li>
|
||
<li class=""><strong>not equals</strong>: Inverse of exact match</li>
|
||
<li class=""><strong>contains</strong>: Checks if the <code>match_text</code> is found within <code>input_text</code></li>
|
||
<li class=""><strong>starts with</strong>: Checks if <code>input_text</code> begins with <code>match_text</code></li>
|
||
<li class=""><strong>ends with</strong>: Checks if <code>input_text</code> ends with <code>match_text</code></li>
|
||
<li class=""><strong>regex</strong>: Matches on a case-sensitive pattern</li>
|
||
</ul>
|
||
<p>By default, all operators are case insensitive except <strong>regex</strong>.
|
||
<strong>regex</strong> is always case sensitive, and you can enable case sensitivity for all other operators in the <a href="#if-else-parameters" class="">If-Else parameters</a>.</p>

|
||
<p>The following example uses the <strong>If-Else</strong> component to check incoming chat messages with regex matching, and then output a different response depending on whether the match evaluated to true or false.</p>

<p><img decoding="async" loading="lazy" alt="A conditional router connected to two OpenAI components" src="/assets/images/component-conditional-router-1fb27526613395545592fc9166c75c27.png" width="3532" height="3044" class="img_ev3q"></p>
|
||
<ol>
|
||
<li class="">
|
||
<p>Add an <strong>If-Else</strong> component to your flow, and then configure it as follows:</p>
|
||
<ul>
|
||
<li class="">
|
||
<p><strong>Text Input</strong>: Connect the <strong>Text Input</strong> port to a <strong>Chat Input</strong> component or another <code>Message</code> input.</p>
|
||
<p>If your input isn't in <code>Message</code> format, you can use another component to transform it, such as the <a class="" href="/type-convert"><strong>Type Convert</strong> component</a> or <a class="" href="/parser"><strong>Parser</strong> component</a>.
|
||
If your input isn't appropriate for <code>Message</code> format, consider using another component for conditional routing, such as the <a class="" href="/data-operations"><strong>Data Operations</strong> component</a>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p><strong>Match Text</strong>: Enter <code>.*(urgent|warning|caution).*</code> so the component looks for these values in incoming input. The regex match is case sensitive, so if you need to look for all permutations of <code>warning</code>, enter <code>warning|Warning|WARNING</code>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p><strong>Operator</strong>: Select <strong>regex</strong>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p><strong>Case True</strong>: In the <a class="" href="/concepts-components#component-menus">component's header menu</a>, click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-sliders-horizontal" aria-hidden="true"><line x1="21" x2="14" y1="4" y2="4"></line><line x1="10" x2="3" y1="4" y2="4"></line><line x1="21" x2="12" y1="12" y2="12"></line><line x1="8" x2="3" y1="12" y2="12"></line><line x1="21" x2="16" y1="20" y2="20"></line><line x1="12" x2="3" y1="20" y2="20"></line><line x1="14" x2="14" y1="2" y2="6"></line><line x1="8" x2="8" y1="10" y2="14"></line><line x1="16" x2="16" y1="18" y2="22"></line></svg> <strong>Controls</strong>, enable the <strong>Case True</strong> parameter, click <strong>Close</strong>, and then enter <code>New Message Detected</code> in the field.</p>
|
||
<p>The <strong>Case True</strong> message is sent from the <strong>True</strong> output port when the match condition evaluates to true.</p>
|
||
<p>No message is set for <strong>Case False</strong> so the component doesn't emit a message when the condition evaluates to false.</p>
|
||
</li>
|
||
</ul>
|
||
</li>
|
||
<li class="">
|
||
<p>Depending on what you want to happen when the outcome is <strong>True</strong>, add components to your flow to execute that logic:</p>
|
||
<ol>
|
||
<li class="">
|
||
<p>Add a <strong>Language Model</strong>, <strong>Prompt Template</strong>, and <strong>Chat Output</strong> component to your flow.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>In the <strong>Language Model</strong> component, enter your OpenAI API key or select a different provider and model.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect the <strong>If-Else</strong> component's <strong>True</strong> output port to the <strong>Language Model</strong> component's <strong>Input</strong> port.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>In the <strong>Prompt Template</strong> component, enter instructions for the model when the evaluation is true, such as <code>Send a message that a new warning, caution, or urgent message was received</code>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect the <strong>Prompt Template</strong> component to the <strong>Language Model</strong> component's <strong>System Message</strong> port.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect the <strong>Language Model</strong> component's output to the <strong>Chat Output</strong> component.</p>
|
||
</li>
|
||
</ol>
|
||
</li>
|
||
<li class="">
|
||
<p>Repeat the same process with another set of <strong>Language Model</strong>, <strong>Prompt Template</strong>, and <strong>Chat Output</strong> components for the <strong>False</strong> outcome.</p>
|
||
<p>Connect the <strong>If-Else</strong> component's <strong>False</strong> output port to the second <strong>Language Model</strong> component's <strong>Input</strong> port.
|
||
In the second <strong>Prompt Template</strong>, enter instructions for the model when the evaluation is false, such as <code>Send a message that a new low-priority message was received</code>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>To test the flow, open the <strong>Playground</strong>, and then send the flow some messages with and without your regex strings.
|
||
The chat output should reflect the instructions in your prompts based on the regex evaluation.</p>
