A lot of tiny big wins about create-t3-app

[t3dotgg]

There's a lot in here I think we should add. Going to chat w/ the core maintainers and see what our path forward is

Closing as completed. We have decided not to implement the test and CI parts for now, and the VSCode stuff is up for discussion in PR #228. Thank you very much for all the suggestions and enhancements!

Any monorepo recommendations that you would like to add? 🙏

@zomars, I think monorepo is out of scope for create-t3-app, ask that question in https://github.com/trpc/trpc/discussions :)

Subscribed. I want to follow up.

Safe environment variables
Environment variables should be validated when a project is built. Having the wrong env vars is a very common production issue that is hellish as you usually don't notice it straight-away. It's better to just crash the build if something's wrong.
Zod to the rescue!

https://github.com/trpc/examples-next-prisma-starter/blob/a07a8d1bd1ed4a9af4fd7cd6130ee92383082419/next.config.js#L3
It's a .js-file because Next.js doesn't support next.config.ts, but it can still be validated by TypeScript: https://github.com/trpc/examples-next-prisma-starter/blob/a07a8d1bd1ed4a9af4fd7cd6130ee92383082419/tsconfig.json#L25-L31

Implemented in #147
