Solid Router: The Complete Guide

A practical guide to Solid Router for building fast, reactive, and maintainable navigation in SolidJS apps.

Master Solid Router with this focused, hands-on guide. Learn the fundamentals of route configuration, navigation, and parameters, then dive into advanced topics like data loading, async handling, prefetching, and performance tuning. Whether building SolidJS SPAs or SolidStart apps, this book equips you with the practical skills to ship fast, scalable, production-ready experiences.

Every modern web application needs navigation. Whether it is a small single-page app or a full-fledged platform with nested layouts, dynamic segments, and preloaded data, routing is the connective tissue that ties the user experience together. In the SolidJS world, that job is handled by Solid Router.

This book provides a focused and practical guide to Solid Router.

The content presented here is adapted from my larger work, SolidJS: The Complete Guide. In that book, routing is covered alongside the broader fundamentals of SolidJS, including reactivity, component design, state management, server-side rendering. Because routing is a distinct and essential subject, I have extracted the original chapter to serve as a standalone reference for developers who wish to study this topic in depth.

If you are already comfortable with SolidJS basics and want to dive straight into building real applications with routing, this book is for you. It is lean, focused, and ready to get you up and running.
