Investigação de técnicas de implementação de variabilidade para frameworks javascript modernos

Abstract

In a software developement context, Software Product Line (SPL) is an approach to support the implementation of similar software products with quality and efficiency, based on a systematic identification and management of the variability present in the products’ features. One of the programming languages used for software development is JavaScript (JS), which is one of the fastest growing programming languages. In its ecosystem, organizations develop frameworks such as Angular and Ionic. However, there is not evidence available in the literature addressing SPL development through variability implementation techniques using JS and its related frameworks. This work aims to investigate the applicability of variability implementation techniques (e.g. parameters, design patterns, frameworks, components and services) in modern JS frameworks. In order to carry out this research, a set of evaluation criteria were defined aiming to measure the effort expended by the developer for the implementation. In addition, a pilot project was developed using the variability implementation techniques to understand their characteristics when applied to SPLs using JS with the Angular framework. With the prior implementation knowledge, the techniques were investigated in a case of study, where it was possible to analyze and identify the benefits and deficiencies of each variability implementation technique in a real context project. All techniques were applicable to the Angular and Ionic technologies, except for the framework technique that presented a limitation to automatically compose the features in the process of derivation of the final system. For the case study, components and services combined as design patterns was the candidate technique for development because it meets a larger number of quality criteria.
