Server-side tracking for Next.js
Next.js is arguably the best-positioned framework here for server-side tracking. You can proxy a first-party endpoint through a rewrite on your own domain, emit money events from route handlers, and keep the whole thing in one deployment. Very little of that requires separate infrastructure.

Next.js server-side · what breaks
What goes wrong on Next.js
- 01
App Router navigation isn't a page load
So page-view-bound events fire once and stop.
- 02
Server components run no client effects
Code you expected to execute simply doesn't.
- 03
Events split between server and client
Without a deliberate decision about which does what.
- 04
Hydration timing
Same as any React app.
Next.js server-side · the fix
What changes — Next.js server-side
Route changes emitting events
From a persistent client component.
Money events from route handlers
Server-side, in the same codebase.
A first-party endpoint via rewrite
On your own domain, no separate infrastructure.
Next.js server-side · architecture
What Next.js exposes to a server container
The best-positioned framework in this cluster for doing it properly.
- 1
Money events from route handlers
Server-side, same deployment.
- 2
First-party endpoint via rewrite
Your own domain, no extra infrastructure.
- 3
Cookies set in middleware
In an HTTP response, so Safari's script cap doesn't apply.
- 4
Backend ID as the deduplication key
Issued where the transaction is recorded.
- 5
Consent enforced server-side
Before dispatch.
Next.js server-side · diagnose
Where Next.js tracking breaks, in diagnostic order
Each check rules out a class of cause, so by the last one there is usually a single explanation standing.
- 01
Navigate between routes and watch for events
One event then silence is the App Router signature.
- 02
Check whether tracking code sits in a server component
Effects there never run.
- 03
Confirm where the money event is emitted
Client or route handler.
- 04
Check whether cookies are set in middleware
The difference between 7 days and 400 in Safari.
- 05
Reconcile against backend records
For a closed month.

The QA evidence — Next.js server-side
Run on Next.js specifically, on a live conversion rather than in preview mode.
Source of truth
your backend order or CRM records
- Route changes confirmed emitting events across App Router navigation.
- Money events confirmed arriving from a route handler.
- First-party cookies confirmed persisting past seven days in Safari on a real device.
- Endpoint confirmed served from your own domain via rewrite.
- Counts reconciled against backend records for a closed month.
- Reconciled over a fully closed window, matched per record rather than on totals.
- Re-checked 30 days later, and after any platform update.

Next.js server-side · when not to buy
When you don't need this on Next.js
Worth reading before you buy anything, from us or anyone.
- If your Next.js app already emits route-change events and sources money events server-side, you've done the work.
- Your engineers can do all of this in their own codebase, and on Next.js it's less work than on any other framework here.
- The rewrite trick is publicly documented and takes an afternoon. You may not need help with it.
- Reconcile against your backend before assuming anything is broken.
Next.js server-side · what we deliver
What the server-side build gives you on Next.js

FAQ
Next.js server-side questions, answered
The best-positioned framework in this cluster. You have a server in the same codebase, rewrites for first-party serving and middleware for cookies.
Often not. A rewrite plus route handlers covers a lot of what a container would do.
Set them in middleware, in an HTTP response. The seven-day script cap applies to document.cookie, not to Set-Cookie.
A backend-issued ID from wherever the transaction is recorded.
