Neodrag is a multi-framework JavaScript library that provides drag-and-drop functionality across React, Svelte, Vue, SolidJS, and vanilla JavaScript. It features a small bundle size (3.46KB), server-side rendering compatibility, TypeScript support, and consistent behavior across all supported frameworks through shared core logic.

Literate is a modern literate programming tool that allows developers to write programs as narrative documents with embedded code blocks. It supports any programming language, uses Markdown syntax for easy readability, generates both executable code and HTML documentation, and includes features like syntax highlighting, error reporting, and automatic hyperlink generation between code sections.

Developers are increasingly using Tinybird to track LLM usage, costs, and performance in AI applications. A new app template called the LLM Performance Tracker allows users to generate real-time data visualizations. The core components include a Tinybird datasource, a Tinybird pipe, a React component, and an AI API route. The backend processes user input to generate chart parameters, while the frontend visualizes the data. This approach emphasizes the importance of performant analytics backends and cautious LLM usage for secure and scalable data visualization.

SOLID principles are five essential design rules that help JavaScript developers write cleaner, maintainable code. The guide covers Single Responsibility (one function per purpose), Open/Closed (extend without modifying), Liskov Substitution (subclasses must be replaceable), Interface Segregation (avoid bloated interfaces), and Dependency Inversion (depend on abstractions). Each principle includes practical JavaScript examples showing violations and proper implementations, plus real-world applications and common interview questions.

Learn how to build a personal AI assistant using LangGraph, Vercel AI SDK, and Next.js. This guide walks through integrating various tools such as Gmail, Google Calendar, and Google Drive securely by leveraging Auth0 for authentication and token management. The tutorial covers both unauthenticated tools like calculators and authenticated tools for accessing personal data, exemplified by implementing a Gmail search and draft feature.
