Description: DataWeave utilities. It is dedicated to DataWeave 2.x

Usage

Maven Dependency

First import maven dependency to UDWL

<dependency>
	<groupId>com.ambassadorpatryk</groupId>
	<artifactId>ultimate-dw-library</artifactId>
	<version>1.0.0</version>
</dependency>

Usage

Below you can see simple transformation using one of the functions from UDWL.

%dw 2.0
output application/json skipNullOn="everywhere"
import generateSecureAWSHeaders from dw::com::ambassadorpatryk::aws::Auth
---
generateSecureAWSHeaders(
	'POST', 
	'us-east-1', 
	'ssm',
	'AmazonSSM.GetParameter', 
	'/', 
	'', 
	payload, 
	Mule::p('secure::aws.accessKey'), 
	Mule::p('secure::aws.secretKey'))

At second line we import Filter.dwl from dw/com/ambassadorpatryk/utils folder. Instead of slash character you need to use two colons.  In order to use function from emptiness_filter you need to refer to specific function/variable like in the fifth line.
