Next.js SDK

@cohorly/nextjs re-exports <CohorlyProvider> / useCohorly() from the React SDK and adds createCohorlyProxy(), a first-party ingestion route handler so your project token never has to leave the server.

Install

bash

pnpm add @cohorly/nextjs
# or: npm install @cohorly/nextjs

Requires Next.js 13+ and React 18+ (peer dependencies).

Two token modes

There are two ways to attach your project token to ingested data. Pick one.

1. Client-side (token in the browser bundle)

Pass token directly to <CohorlyProvider>. Simplest, but the token is visible in your client JS.

tsx

// app/layout.tsx
import { CohorlyProvider } from "@cohorly/nextjs";

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html>
      <body>
        <CohorlyProvider
          apiHost="https://api.cohorly.com"
          token="YOUR_PROJECT_TOKEN"
          trackPageviews
        >
          {children}
        </CohorlyProvider>
      </body>
    </html>
  );
}

2. Server-side proxy (token never leaves your server)

Point the client SDK at a first-party API route and let the route handler inject the token server-side. Create the route with createCohorlyProxy():

// app/api/cohorly/[...path]/route.ts
import { createCohorlyProxy } from "@cohorly/nextjs/server";

export const { POST } = createCohorlyProxy({
  apiHost: "https://api.cohorly.com",
  token: "YOUR_PROJECT_TOKEN", // injected server-side into every forwarded body
});

Then point apiHost at your own route and omit token on the client:

tsx

// app/layout.tsx
<CohorlyProvider apiHost="/api/cohorly" trackPageviews>
  {children}
</CohorlyProvider>

The proxy forwards POST /api/cohorly/track, /engage, and /alias upstream, stamping token into each forwarded body server-side. This keeps the token out of the browser bundle, hides apiHost, and dodges ad-blockers that block direct requests to third-party analytics hosts.

createCohorlyProxy(options)

Option	Type	Notes
`apiHost`	string	Required. Upstream Cohorly server URL.
`token`	string	Injected into every forwarded body.
`allowedPaths`	string[]	Defaults to `["track", "engage", "alias"]`.

Returns a { POST } route handler. Use the client provider and useCohorly() exactly as in the React SDK.
