The Future of GenAI in Backend Web Development
While the current applications of GenAI in backend development are impressive, the future holds even greater potential. We can expect GenAI to become more conversational, better able to interact with developers (and non-developers) to define requirements and turn those requirements into project plans, documentation, test cases, and code.
Perhaps some software won't need to be written at all. Business users can merely tell the GenAI system what they wish to accomplish, and the software will create ad-hoc applications that perform that exact task.
FAQs About GenAI and Backend Development
Here are some frequently asked questions about GenAI and its role in backend development:
Q: How can I use generative AI in coding?
A: GenAI can be used during many parts of the software development process. For coding, the GenAI must be trained on the specific programming language used for your project. Give the system very specific commands, called prompts, for what you wish to do, and it should be able to generate finished source code that’s ready to be compiled and run or added into your source code management system or online repository, such as Github.
Q: Can I build software using AI?
A: You can build software using GenAI in many ways. It can help generate code, though at this stage of the technology’s development, that code performs only relatively simple functions. GenAI’s real value, at least now, is to assist your development team with tasks such as planning projects, designing architecture, generating test cases, performing code reviews, and writing documentation.
Q: How will AI be a challenge in software development?
A: GenAI is still new, especially for use within a development team. Arguably the biggest challenge will be acceptance of the technology by skeptical developers who are comfortable with the status quo and resistant to changes in their methodologies, tool chains, and processes. There may also be some who view GenAI as a potential threat to their careers.
Beyond that, each organization will need to build confidence in GenAI software. Is the code solid, safe, and performant? Are the test cases accurate and do they offer full code coverage? Does documentation meet the requirements? The initial stages of GenAI-assisted software development will be largely experimentation. The results, if the technology is applied correctly, should be greatly enhanced developer productivity, bringing better software into production faster, and at lower cost, to help the organization serve its mission.
Finally, law is still evolving as to the ownership and protectability of AI generated code. Can you register a copyright in software where AI was used to generate some of the code? If using a commercial GenAI system, do the Terms of Service mandate that you license back any output to the owner of the model? You should investigate these issues before embarking on use of GenAI in software development.
