How to print the current date ? in MuleSoft 129

 How to print the current date ? in MuleSoft

There are two primary ways to print the current date in MuleSoft 4:

1. Using the now function in DataWeave:

DataWeave offers a versatile and flexible approach for working with dates and times. Here's how to achieve this:

%dw 2.0
// Get the current date and time
var currentDateTime = now()

// Optionally format the date as needed
var formattedDate = currentDateTime format "yyyy-MM-dd";

// Print the formatted date (or directly use currentDateTime)
output = formattedDate;


  • The now function returns a DateTime object representing the current date and time.

  • You can optionally use the format function to format the date according to your desired format string (e.g., "yyyy-MM-dd" for year-month-day).

  • The final output variable (output) holds the formatted date or the original DateTime object if no formatting is applied.

2. Using MEL (Message Expression Language):

While less flexible than DataWeave, MEL can be used for basic date formatting. Here's the syntax:


#[(payload as Date).format('yyyy-MM-dd')]


  • This expression casts the payload (assuming it's a date) to a Date object.

  • The format function is used to convert the date to the specified format string.

Choosing the Right Approach:

  • DataWeave: This is the recommended method due to its readability, ability to handle various date formats, and potential for further manipulation of the date object.

  • MEL: While functional for basic formatting, MEL expressions can become complex for intricate date processing or conditional logic.

Additional Considerations:

  • Ensure the payload is a valid date type before applying these methods.

  • Error handling can be incorporated within DataWeave or MEL to gracefully handle cases where the payload might not be in the expected format.
