Why Conditional routes in NextJS? - Purpose & Use Cases

The Big Idea

Discover how to keep your app secure and smooth without messy code everywhere!

The Scenario

Imagine building a website where some pages should only be seen by logged-in users, and others by guests. You try to check user status on every page manually and redirect them yourself.

The Problem

Manually checking user status and redirecting on every page is tiring and easy to forget. It leads to bugs where users see pages they shouldn't or get stuck in loops. It also clutters your code with repeated checks everywhere.

The Solution

Conditional routes let you define rules once that control who can see which pages. The framework handles the checks and redirects automatically, keeping your code clean and your app secure.

Before vs After

✗ Before

if (!user) { router.push('/login') } // on every page

✓ After

export const routes = [{ path: '/dashboard', authRequired: true }]; // centralized rules

What It Enables

Conditional routes make it easy to control access and navigation based on user state, improving security and user experience.

Real Life Example

A shopping site shows the cart page only to logged-in users and redirects guests to sign in automatically.

Key Takeaways

Manual route checks are repetitive and error-prone.

Conditional routes centralize access control logic.

This leads to cleaner code and safer navigation.
