REST
(REpresentational State Transfer), relying on
resources
as its architectural unit, is currently a popular architectural choice for building Web-based applications. It is shown that
design patterns
—good solutions to recurring design problems—improve the design quality and facilitate maintenance and evolution of software systems.
Antipatterns
, on the other hand, are poor and counter-productive solutions. Therefore, the detection of
REST
(anti)patterns is essential for improving the maintenance and evolution of
RESTful
systems. Until now, however, no approach has been proposed. In this paper, we propose
SODA-R
(Service Oriented Detection for Antipatterns in
REST
), a heuristics-based approach to detect (anti)patterns in
RESTful
systems. We define detection heuristics for eight
REST
antipatterns and five patterns, and perform their detection on a set of 12 widely-used
REST
APIs
including BestBuy, Facebook, and DropBox. The results show that
SODA-R
can perform the detection of
REST
(anti)patterns with high accuracy. We also found that Twitter and DropBox are not well-designed,
i.e.
, contain more antipatterns. In contrast, Facebook and BestBuy are well-designed,
i.e.
, contain more patterns and less antipatterns.
