UX in the Terminal: How to Write Good CLI Applications

The blog article on Tweag discusses how the Topiary project has enhanced the user experience in Command Line Interfaces (CLI) by implementing user-friendly interfaces and practices. The authors analyze key features that have contributed to the improved UX, such as clear messaging, intuitive design, and command structure. With these enhancements, users can more easily use data-supporting tools and experience less frustration while working in the terminal.

Increasing accessibility and clarity of CLI commands is essential, especially for new users and developers. An improved UX fosters faster onboarding for newcomers to the tech ecosystem and reduces the entry barrier to complex projects. The authors emphasize the importance of testing UX early on to gather feedback from real users, allowing for error correction and interface refinement.

Topiary employs various techniques, such as contextual hints and straightforward documentation, to guide users through complex processes. The article also presents specific examples of command upgrades that can lead to tangible benefits, such as increased tool adoption and improved user experience. Finally, the authors encourage other projects to pay more attention to UX in their CLI tools, to better care for their user communities.

In summary, the article highlights the critical issue of improving CLI tool usability through better UX. Topiary serves as an excellent example of how changes can be made that have a real impact on user experience. By optimizing interfaces and focusing on real user needs, projects can become more friendly and effective. This not only increases satisfaction but also community engagement, which is crucial for any open-source project.
