An IT integrator's corporate site on Next.js

We needed a fast bilingual site that indexes in both Yandex and Google, holds strong Core Web Vitals, and does not drift visually from the company's other products.

There was an extra constraint — the host: one virtual CPU and one gigabyte of RAM. A Next.js build does not fit in that memory, so the usual "push the source and build on the server" workflow simply does not apply.

The site runs on Next.js with the App Router: all 64 pages are generated ahead of time, so the server returns finished HTML with no per-request work. RU/EN localisation is handled by router rules rather than middleware, which removes JavaScript from every request — noticeable on a single core.

Fonts are self-hosted through next/font with the Cyrillic subset included; there are no requests to external font services at all. Animations, the carousel and the accordion are built on CSS and native elements instead of libraries, saving roughly 200 KB of JavaScript.

The build runs on a developer machine and a 14 MB artefact is shipped to the server, where activation is a symlink switch. Rolling back to the previous release is one command. TLS certificates are issued and renewed automatically, with no certbot and no cron job.
