Recent notes

03.4 · State machines with `as const`2h ago
`as const` makes TS infer the string literal, not `string`. Applied to fetch states, it finally stopped asking for manual narrowing at the call site.
03.3 · Typed strategy without boilerplateyesterday
The Record<Kind, Handler> version reads better than the class one. TS complains if I forget a new case in the enum.
03.2 · Result<T, E> instead of try/catchJun 12
Curious how well this pairs with tRPC. Going to try it on the billing service this week.
