# Transpiler-Based Architecture Design Model for Back-End Layers in Software Development
## 3 Transpiler-Based Design Model for Back-End Layers
### Pros and Cons
#### 3.6.2 Cons  
* Focus on Target Audiences: Although design formulation starts from the concept of a general-purpose solution, the proposed design may not be suitable for every software project. This architecture is best suited for specific scenarios with well-defined characteristics, and may not be the ideal choice for all projects. Therefore, it is important for development teams to carefully evaluate whether the proposed design aligns with the specific requirements and objectives of their projects before adoption.
* Additional Effort: Additional effort and resources may be required to create and maintain the transpiler and its associated components. This could include the development time for the transpiler itself as well as ongoing updates and maintenance to ensure compatibility with new target languages and technologies. Additionally, the need to train developersin the use of the transpiler and associated tools could add to the overall learning curve and resource requirements.
* Associated Costs: Because this approach requires the use of multiple technologies and tools, including the transpiler, nest implementations, and post-build utility, there may be additional costs for training, maintenance, and ongoing support. Additionally, the use of this design may require a development team with specialized skills, which could further increase costs compared to a single-language software solution.
* New Programming Languages: The need for developers to learn a new programming language specific to the transpiler could increase the learning curve, and may require additional training resources that add to overall development costs. Additionally, developers who are already familiar with the target language may not be interested in learning a new language, which could make it difficult to implement the proposed design.
* Lack of Documentation: Another potential disadvantage of using the proposed design is that it is a relatively new technology, meaning that there may be a lack of documentation and community support. Consequently, developers may face challenges around troubleshooting concerns or finding resources to learn and improve their skills. In addition, a limited number of experts may be available to assist with complex problems, which could lead to delays in development and deployment.
* Difficulty in Debugging: Owing to the complex nature of the transpilation process, the multiple technologies involved, and the generation of multiple layers of code, it can be challenging to identify and isolate errors that may arise in the system. This can lead to longer development and testing times, and may require specialized knowledge and tools to effectively debug the system.
* Need for Standardized Libraries: There may be a lack of available libraries in the target languages. Although transpilers can generate code in various programming languages, not all libraries may be available in these languages, leading to limitations in functionality or additional development efforts being required to recreate or find alternative solutions. This can add complexity and potentially increase project costs. Certainly commonly available imports may not be usable, or may need to be implemented from scratch.
