New TypeScript Koa2 server generator

[wing328]

We would like to create a new server generator for TypeScript Koa2:

Similar to how other new generators are created, we can re-engineer the new generator and template based on TypeScript Koa2 server-side code.

In near future, I will not use a Swagger/OpenApi in my business, so I would not to spend time for my old code. I think It is good way to create new product if anyone need more maintained code.

Understood. Let's see if anyone from the community is interested in moving this project forward with new code written from scratch or based on the code you've written so far.

All the best with your new projects.

I haven't used a generator, but I'm interested in creating a koa2 generator.

moving this project forward with new code written from scratch or based on the code you've written

hmm....
...I think both are good.

I haven't base code that I think best for generator now.
I want to think about it, but I need time a little bit more.
If someone is in a hurry, I think this code is good for a base.
