Designing a Telegram Bot with Context and Update Handling in TypeScript

export const MessageContextRef = GenericTag<MtcuteMessageContext>(
  "@ref/MessageContext",
);

export class MessageContext
  extends Effect.Service<MessageContext>()("@service/MessageContext", {
    effect: Effect.gen(function* () {
      const update = yield* MessageContextRef;

      return {
        update,
        answerText: (
          text: InputText,
          params?: CommonParams,
        ): Effect.Effect<void, Error> => Effect.tryPromise({
            try: () => update.answerText(text, params as any),
            catch: () => new Error("answerText"),
          }),
      };
    }),
  }) {}

# handler
handler(context, state).pipe(
  Effect.provide(MessageContext.Default),
  Effect.provideService(MessageContextRef, context),
)
