TypeScript Intersection Types: When They're Your Best Friend, and When They're Quietly Lying to You
Intersection types in TypeScript seem simple: combine two types. But what happens when those types have overlapping properties with different definitions? TypeScript won't always warn you, leading to silent failures that can be incredibly hard to debug. I'll show you when they work perfectly, when t

Building a truly offline-first application that feels instant, even with complex data, is a monumental task. ElectricSQL promises to make this a reality by extending your Postgres database directly to the client, keeping everything in sync and highly available.
When Your API Contract Becomes Your Type System
Schema validation is often an afterthought, bolted on at the edge of your application. But what if your validation library could deeply integrate with TypeScript, generating types directly from your schemas? Zod changes the game by making your runtime validation the source of truth for your static t
When Your Database Needs a Type-Safe, Object-Oriented Interface
