Client-side Routing Concepts
Learn SPA routing concepts: paths map to views, navigation updates URL and UI without full reload; simple hash-based demo.
Client-side Routing Concepts is a free React Academy lesson on CoddyKit — lesson 1 of 3. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the React Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.
What is client-side routing?
Goal: See how client-side routing lets apps switch screens without reloading the page.
- SPA vs full page reload
- Path → view mapping
- History updates
SPA vs MPA
SPA: one HTML page, JS swaps views. MPA: server sends a new page per URL. SPAs feel faster because navigation avoids full reloads.
Paths, params, active
Path identifies a view (e.g., /about). Params carry data (e.g., /users/42). Mark the current link as active for clarity.
Demo: simple routing
A tiny hash-based router: links update #path; the app listens to hashchange and renders the matching view.
<div id="root"></div>
History and navigation
Routers update the URL and history so Back/Forward work. Views change instantly without reloading the whole document.
Tips & next steps
Tips:
- Keep links clearly active.
- Handle unknown paths (404).
- Use a library later for nested routes and params.

Recap
Recap: Client-side routing maps paths to views, updates URL/history, and avoids full reloads for fast navigation.
