Some common types of applications that use Velocity are:
AWS API Gateway body mapping template.Web applications: Web developers render HTML page structures. The content is populated with dynamic information. The page is processed with VelocityViewServlet or any of a number of frameworks that support Velocity.
Automatic emails: Many applications generate automatic emails for account signup, password reminders, or automatically sent reports. Using Velocity, the email template can be stored in a text file, rather than directly embedded in Java code.
XML transformation: Velocity provides an Ant task, called Anakia, which reads an XML file and makes it available to a Velocity template. A common application is to convert software documentation stored in a generic "xdoc" format into a styled HTML document.
AWS API Gateway uses Apache Velocity engine for body mapping templates - JSON is output.
The syntax and overall concept of the Apache Velocity templates is similar to the syntax of the older WebMacro template engine, which is now also an open source project. [citation needed]
