First Integration

1. What will you learn?​

In this introductory lesson, we will get acquainted with the main components of the "Integrations" module and create a practical example. You will learn how to:

  • Use the Function node to write your own functions in JavaScript.
  • Apply the Template node to generate text templates with dynamic data.
  • Configure the Inject, Debug, and Switch nodes to initiate flows, check results, and set conditions.

2. Inject Node​

The Inject node will be used to simulate input data and start the flow.

3. Function Node​

We will use the Function node to pass an input number.

  • Code in Function Node: 
    msg.payload = 5; // Input number
    return msg;

Here we set the number 5, which we pass into the flow.

4. Switch Node:​

The Switch node will be used to check whether the number is positive, negative, or zero, and pass data accordingly.

  • Configuration:
    • If the number is greater than 0, pass to the "Positive" branch.
    • If the number is less than 0, pass to the "Negative" branch.
    • If the number is equal to 0, pass to the "Zero" branch.

5. Template Node:​

In the Template node, we will create a template for outputting a message.

  • Template in Template Node: 
    Result of the check: {{payload}}

This node will substitute the text generated in the previous node and prepare it for output.

6. Debug Node:​

The Debug node will output the result to the console so we can see the final message.

  • Configuration: Set the output to msg.payload to display the generated message in the console.

7. Result:​

If the number passed into the flow is 5, in Debug you will see the message:

Result of the check: The number is positive

If you change the number to -3, the result will be:

Result of the check: The number is negative

If the number is 0, the result will be:

Result of the check: The number is zero
