    playwright-soak repeats a user flow a few hundred times inside a Playwright test, forces GC, and fails the build if DOM nodes, listeners or heap keep piling up. A smoke alarm for the slow leaks that make a day-long tab drag.

-   ## [Why I built llm-queue: one local model, one queue](https://asmyshlyaev177.dev/blog/why-i-built-llm-queue.md)
    
    June 28, 2026
    
    One local LLM (Ollama) behind an OpenAI-compatible HTTP API, so every process shares one serialized queue instead of thrashing the model. On my 6 GB GPU that made everything roughly four times faster.

-   ## [Testing Next.js SSR with Playwright: record real responses instead of writing mocks](https://asmyshlyaev177.dev/blog/testing-nextjs-ssr-playwright-record-replay.md)
    
    June 17, 2026
    
    Playwright can mock browser requests, but not the fetches Next.js makes during SSR. How I record real API responses once and replay them on CI. It's the VCR pattern Ruby nailed years ago, rebuilt for SSR.

    The story of building state-in-url: turning the browser URL bar into real, type-safe React state — the design decisions and trade-offs, from first prototype through the testing pain to launch.
