It's really simple to add type-safety with @drizzle.team for any @sdk.vercel.ai messages you store in your database
// ...
import type { Message, Attachment } from "ai";

export const message = pgTable("message", {
  id: text("id").primaryKey(),
  chatId: text("chatId")
    .notNull()
    .references(() => chat.id),
  
  // infers: "data" | "user" | "system" | "assistant"
  role: text("role", { enum: ["data", "user", "system", "assistant"]}).notNull(),
  
  // infers: (TextUIPart | ReasoningUIPart | .... )[] | undefined
  parts: json("parts").notNull().$type<Message["parts"]>(),
  
  content: text("content").notNull(),
  attachments: json("attachments").notNull().$type<Attachment[]>(),
  createdAt: timestamp("createdAt").defaultNow().notNull(),
});

You can directly plug in Tailwind variables when you're restyling shadcn/ui #designsky
@import "tailwindcss";

@custom-variant dark (&:is(.dark *));

@theme inline {
  --color-background: var(--background);
}

:root {
  --background: var(--color-white); 
  /* instead of --background: oklch(1 0 0); */
}

.dark {

ChatGPT 4o:

You said:
What would be an easy way to calculate the tariffs that should be imposed on other countries so that the US is on even-playing fields when it comes to trade deficit? Set minimum at 10%.


ChatGPT said:
An easy way to estimate tariffs to balance the trade deficit (i.e. level the playing field) is to use a proportional tariff formula based on the trade deficit with a given country. Here's a basic method:

Step-by-step: Proportional Tariff Formula
Formula:

text
Copy
Edit
Tariff % = 10% + (Trade Deficit with Country / Total Imports from Country) × 100
Where:

Trade Deficit = Imports from Country − Exports to Country

Minimum Tariff = 10%

If there is no deficit or a surplus (exports ≥ imports), apply only the 10% base tariff.

pretty cool to see @netlify.com is using @trpc.io and @tanstack.com query as defaults for building extensions
+RPC integration
The Netlify SDK includes an optional integration with tRPC 7, a community-maintained solution for writing queries that offer end-to-end type safety.
By default, extensions created by running npm create @netlify/sdk@latest include all
the boilerplate necessary to write tRPC procedures. You can write new procedures 7 and call them from your extension Ul. For an overview of the boilerplate files, refer to the endpoints tRPC integration documentation.
You can update the boilerplate your tRPC application router:
