This issue requests adding Jest as an option when creating a new app via nwb's CLI. The discussion in the comments (30 comments) may contain specific requirements or disagreements. To proceed, a contributor should review the existing prompts in the CLI code (likely in bin/ or src/) to understand how other testing frameworks are handled, and then implement a similar pattern for Jest. The maintainer has not provided a clear specification, so the contributor may need to propose a concrete approach.
