Modern web applications are no longer just "sites." They are long-lived, highly interactive systems that span multiple runtimes, global content delivery networks, edge caches, background workers, and increasingly complex data pipelines. They are expected to load instantly, remain responsive under poor network conditions, and degrade gracefully when something goes wrong.
With PyCharm 2026.1, users can leverage a comprehensive set of editing and formatting tools for modern web languages, including basic React support with code completion and navigation.
The request for its API val request = Request[IO](Method.POST, uri"/jobs")val api = new AsyncJobApi // this will not compile since AsyncJobApi is not defined yet Minimal implementation to make it green: class AsyncJobApi Red test: The API should return a 202 Accepted response: "POST /jobs returns Accepted" in { val request = Request[IO](Method.POST, uri"/jobs") val api = new AsyncJobApi api.routes.orNotFound.run(request).asserting : response => response.status shouldBe Status.Accepted} Make it green: class AsyncJobApi { val routes: HttpRoutes[IO] = HttpRoutes.of[IO] : case req @ POST -> Root / "jobs" => Accepted()} 5.2 Add headers (Trivial Implementation) Red test: add X-Total-Count and Location headers with job ID (only the assertion is shown)
The main promise is isolation: a Docker container that works on an x86_64 Linux machine will work on any x86_64 Linux machine in the same way. Want to quickly set up PostgreSQL for testing? Just run docker run --name postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d --restart=unless-stopped postgres and wait a few seconds. Docker is great for deployment as well as production deployments, and it even supports Windows Server containers these days.
For the past few years, artificial intelligence has been discussed almost exclusively in terms of models. Bigger models, faster models, smarter models. More recently, the focus shifted to agents, systems capable of planning, reasoning, and acting autonomously. Yet the real leap in usefulness does not happen at the model level, nor at the agent level. It happens one layer above, at the level of Skills.
Readable failures. When something breaks, I want to understand why in seconds, not minutes. Predictable setup. I want to know exactly what state my tests are running against. Minimal magic. The less indirection between my test code and what's actually happening, the better. Easy onboarding. New team members should be able to write tests on day one without learning a new paradigm.

Asif on the other hand, is doing something else: He's doing things the Pybites way! He's building with a focus on providing value. We spent a lot of time discussing a problem I'm seeing quite often now: developers who limit themselves with AI. That is, they learn how to make an API call to OpenAI and call it a day. But as Asif pointed out during the show, that's not engineering. That's just wrapping a product.
