Hono RPC provides end-to-end type safety with zero overhead. Learn how it compares to tRPC and GraphQL, and when each shines.
A user sends 10,000 requests per minute to your API. No rate limiting. Your server CPU spikes to 100%. Your database runs out of connections. Every other user sees 503s. One script can take down your entire service — and it happens more often than you think.
Master tRPC for building strongly typed APIs with automatic type inference across your full stack. Learn router setup, validation, middleware, subscriptions, and when tRPC falls short.
Master Zod for runtime validation of untrusted input. Learn schema patterns, parse vs safeParse, transformations, discriminated unions, environment validation, middleware, and API error formatting.
Most HTTP clients give you fetch. reixo gives you Result<T,E> returns, automatic retry with jitter, circuit breakers, request deduplication, LRU caching, GraphQL support, WebSocket/SSE, OpenTelemetry tracing, and a fluent builder API — all in one TypeScript-first package.
reixo is a TypeScript-first HTTP client for Node.js, browsers, and edge runtimes. It bundles retries, circuit breaking, request deduplication, OpenTelemetry tracing, typed error returns, offline queuing, caching, and more — zero dependencies. Here's why it's the HTTP client of 2026.
Express remains the most popular Node.js framework for building REST APIs. In this guide, we'll build a complete, production-ready REST API with authentication, validation, error handling, and a database from scratch.
FastAPI is taking the Python world by storm. It's faster than Flask, easier than Django REST Framework, and comes with automatic docs out of the box. In this guide, we'll build a complete REST API from scratch using FastAPI.
