Do we need src/env.ts, doesn't wrangler types generate typings for that as well now?

[flakey5]

It does but then I don't think we can have the inline comments on the vars

Can't we place those in the wrangler config, or is the intellisense what you're concerned about?

(Would be a cool upstream wrangler PR to read jsonc comments from the line above an env var and use that to generate a typedoc comment)

[flakey5]

Yeah intellisense, but that's really just a personal preference. Also since we have multiple environments would we be duplicating the comments per env in the wrangler file?

[MattIPv4]

I would probably put the comments in the top-level vars definition and not in the environment-specific definitions, but also totally fine w/ keeping the ts file if that's easier 👍
