hydration-overlay: Overlay for hydration errors with explicit diff between renders.
This package helps you identify hydration errors by showing you the differences between the HTML rendered on the server and the client. It works by injecting a script into your app's entry point that reads the HTML from the server, stores it, and then listens for hydration errors. When an error occurs, it stores the resulting HTML and compares it to the stored HTML. If the two are different, the plugin will show you an overlay with the diff.

invariant: Type safe utilities for throwing errors in a declarative way
Invariant is a cool tool that lets you throw errors in a type-safe way. It's like having a built-in safety net for your code. You can even throw responses instead of errors, which is great for handling exceptional situations in a more structured way.
import { invariant } from '@epic-web/invariant'
const creature = { name: 'Unicorn', type: 'Magic' }
invariant(creature.type === 'Fire', 'Creature must be of type Fire')
// Throws: InvariantError: Creature must be of type Fire
reason: A minimalistic Typescript framework for building great LLM apps
RΞASON is a lightweight TypeScript framework that simplifies building awesome LLM apps. Its secret sauce: leveraging your TypeScript type information to guide the LLM, ensuring it delivers the right responses without guesswork.
import { reason } from 'tryreason'
interface Joke {
rating: number;
joke: string;
explanation: string;
}
const joke = await reason<Joke>('tell me a really spicy joke')
// joke object is:
{
"joke": "I'd tell you a chemistry joke but I know I wouldn't get a reaction.",
"rating": 18,
"explanation": "This joke is a play on words. The term 'reaction' refers to both a chemical process and a response from someone. The humor comes from the double meaning, implying that the joke might not be funny enough to elicit a response."
}
sqlauthz: Declarative permissions management for PostgreSQL

holy-loader: A lightweight, customizable top-loader / top loading progress bar
Holy Loader is a neat and flexible top-loading progress bar that works great with React apps, especially Next.js with app router. It's simple to incorporate, extensively customizable with reasonable defaults, and employs a custom scheme for sleek, attractive progress indicators. It also allows you to dynamically adjust the color, height, speed, easing, and more.
import HolyLoader from "holy-loader";
export default function RootLayout({ children }) {
return (
<html lang="en">
<HolyLoader
color="#ff4500"
height="1rem"
trickleSpeed={250}
easing="linear"
/>
{children}
</html>
);
