Fluent interface

This article is about the API design pattern. For the user interface introduced in Microsoft Office 2007, see Microsoft Office 2007 § User interface. For Microsoft's 2017 visual design language, see Fluent Design System.

In software engineering, a fluent interface is an object-oriented API whose design relies extensively on method chaining. Its goal is to increase code legibility by creating a domain-specific language (DSL). The term was coined in 2005 by Eric Evans and Martin Fowler.[1]
