Hey @LashaniPerera
Thanks for picking this up and having a look. I ran into this issue when I tried to find a Forge app set up using a monorepo project structure. In this particular case, I tried to used Nx which generated a Typescript project using project references.
I was considering the renaming approach, however, I do not think this will work because none of the tsconfig files are complete on their own (see my initial post for an example of the base tsconfig file - note that this is the file called tsconfig.json). Renaming will likely also not play nicely with the Nx tooling/CLI as it relies on a certain project structure to work.
Unfortunately, I did not properly keep track of my changes when I tried this out because it was just a first quick test. So I do not have the initial state with project references anymore.
Having said that, to us, it is not super important to solve this specific problem. Instead, we would much prefer if Atlassian would support a Forge project structure that plays nicely with custom UI and Typescript. I have summarized some of our requirements in the README of another attempt we made using Turborepo (unfortunately, we ran into issues there as well).
For us, the ideal situation here would be if Atlassian supports a specific project setup that supports easy building, tunneling, and deployment of Forge custom UI apps using Typescript. Many modern frameworks out there (most prominently Angular) work with a specific project structure which allows them to provide great developer tooling. Additionally, as a developer, it allows me to bootstrap a project within a matter of seconds without having to think of where to put my files, which tooling to use, or scripts to write to build it. I feel, the existing Forge project structure was sufficient for simple sample apps using Forge UI, however, it does not scale well to more complex projects using custom UI and Typescript.
I hope this gives you a better understanding of what we were looking for when we ran into the issue described in this thread.
