Description
This example shows how to parse an incoming JSON message and process it using the JavaScript transformer.
Example Use Case
In this example, we send a JSON message containing two numbers to an HTTP endpoint. This Byte Array of data is transformed to a String. The JavaScript transformer then processes the data and adds up the numbers. The sum is then returned to the HTTP endpoint.
Set up and Run the Example
1 Open this example project in studio and run it
2 Use Postman, curl or REST console to make a POST request using JSON. The message body should contain the following data:
{
"a": 3, "b": 4
}3 If the project is running successfully you should get the following message on your studio console.
