Middleware Basics vs Webhooks
Both are commonly confused. Here is a side-by-side breakdown of what each one does, when to reach for it, and when it would be the wrong choice.
Middleware Basics
Middleware = Code that checks every request before it reaches your app. Like a security guard at the entrance, one checkpoint instead of checking IDs at every door.

Webhooks = automatic notifications from one app to another when something happens. Like getting a text when your package arrives instead of refreshing the tracking page all day.

Use Middleware Basics when
-
Multiple pages need the same check
If 10 pages all need "user must be logged in," that's middleware. Write the check once, apply it everywhere.
-
You want to track every visitor
Want to know who visited what page and when? Instead of adding tracking code everywhere, middleware sees every visitor in one place. Like a guest book at the entrance.
-
You need to block unwanted visitors
Fake accounts, banned users, suspicious activity: stop them at the entrance before they cause trouble. No need to check at every room.
Use Webhooks when
-
You need to know when something happens in another app
Customer paid? Order shipped? Pull request merged? Webhooks tell you immediately. Perfect for payment notifications, shipping updates, or syncing data between services.
-
You want real-time reactions
Send a welcome email the instant someone signs up. Update inventory the moment an order is placed. Webhooks let you react in real-time, not on a 5-minute delay.
-
You're connecting to a third-party service
Stripe, GitHub, Shopify, Twilio: almost every major service supports webhooks. They are the standard way to receive updates from external platforms.
When to avoid each
Avoid Middleware Basics when
-
Only ONE page needs the logic
If only your admin page checks for admin role, just put that check in the admin page. Don't overcomplicate.
-
You're building a tiny app
A 3-page website doesn't need middleware architecture. Keep it simple until you actually need it.
Avoid Webhooks when
-
You only need data once
If you just need to fetch a user's profile one time, use a regular API call. Webhooks are for ongoing notifications, not one-time lookups.
-
You control both systems
If you own both the sender and receiver, you might prefer direct function calls, message queues, or database triggers. Webhooks shine when connecting separate services.
-
You're building a tiny script
A simple script that runs once doesn't need webhook infrastructure. Keep it simple. Poll if you only need data occasionally.
