Is junior built with Next.js?

is this next.js?

Yes, this is a Next.js project. More specifically, it's a pnpm monorepo that's deeply tied to Next.js:

1. The example app (apps/example) is a straightforward Next.js app — it uses next dev, next build, next start, and depends on next@^16.1.6.

2. The core @sentry/junior package (packages/junior) is built as a Next.js plugin/integration:

   • It has next and react as peer dependencies (next >= 15.0.0).
   • Its exports are Next.js-oriented: ./config maps to next-config.js, ./app/layout maps to app/layout.js (App Router), and it exposes route handlers (./handler, ./handlers/webhooks, etc.).
   • It also depends on @sentry/nextjs as a peer dependency.

So the whole project is a Next.js-based AI agent framework — @sentry/junior is a library you plug into a Next.js app, and apps/example demonstrates that usage.
