In the evolving landscape of software development, the nMorph framework introduces a potential advancement in multi-programming language development. This framework is designed to allow developers to code in a single language that can be transpiled into multiple target languages, aiming to maintain single design integrity while offering the potential for customization, technological adaptability, and platform independence. Architecturally, nMorph focus on the back-end, incorporating a layered design that includes components such as ORM & Database Connectors and a dedicated security layer. Central to this construct is the Haxe transpiler, which is designed to transform between languages such as Java, C#, and PHP. The framework also considered the support for connecting databases such as the Oracle, SQL Server, MySQL and PostgreSQL. Also the preparation for running in IIS, Apache, Tomcat, Glassfish and others. A controlled empirical experiment was conducted in which novice programmers used the nMorph framework in comparison with traditional programming languages in a simple banking-like transactional exercise. Results showed that participants took an average of 15.19% longer when using nMorph compared with commonly used programming languages. Despite that, with nMorph they obtained a multi-language and multi-platform software. Some other factors were analyzed about the influence of individual developer proficiency on outcomes, suggesting areas where the nMorph could be refined. This study underscores the relationship between perceived task difficulty, language proficiency, and software development phases. This study was primarily lab-based. There is potential value in further exploring real-world applications and broadening the scope of the framework to assess its broader relevance and efficacy.
