Nested Routes & Route Params
Learn how a parent route renders child views and how route parameters (e.g., /products/42) pass IDs to components.
Nested Routes & Route Params is a free React Academy lesson on CoddyKit — lesson 2 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.
Why nested routes & params
Goal: Understand nested routes (parent pages that render child views) and route params (variable URL parts like /products/42).
Parent and outlet idea
A parent path (e.g., /products) renders layout and an outlet. Child paths (e.g., /products/:id) fill that outlet with specific content.
What are params?
Route params capture values from the URL (like :id). Components read the param to fetch or display the matching record.
Demo: nested + params
Hash-based demo: parent /products shows a list; selecting an item navigates to /products/ID and renders the child view inside.
<div id="root"></div>
Read params & build links
Reading params: parse the URL (or use a router hook) to get id and load data. Linking: build paths like /products/ID from lists.
Tips & pitfalls
Tips:
- Keep parent layout small; render child content in an outlet area.
- Validate params before use.
- Handle not-found ids gracefully.
Route param purpose
Recap
Recap: Parent routes provide layout; child routes render in an outlet. Use route params to capture ids from the URL and show the right record.
