Categories

Tags performance web-development app-development react ux

Build React Server Components without a framework using Forket—a library-agnostic solution that splits code between client and server while maintaining reactivity. By Krasimir Tsonev.

This long piece covers:

  • Mental model
  • What exactly Forket is doing
    • Building a graph
    • Producing a “server” version of the code. Finding client boundaries
    • Producing a “client” version of the code. Finding server actions
    • Annotating client entry points
    • Server actions mapping
  • How to use it
    • At build time
    • At runtime
    • Instrument your HTTP server
    • At least one client entry point

Krasimir Tsonev introduces Forket, a tool to support React Server Components outside of Next.js, by splitting components into client/server versions. Forket generates an abstract syntax tree (AST) graph to identify server-only and client-only code, serializes props for hydration, and handles server actions via global functions.

It works with build tools like Express or Vite to stream React components to the browser. The article emphasizes its framework-agnostic design and provides setup guidance through a config file and runtime glue code. Interesting read!

Modern Node.js patterns for 2025

Categories

Tags javascript web-development app-development nodejs javascript

Node.js has undergone a remarkable transformation since its early days. If you’ve been writing Node.js for several years, you’ve likely witnessed this evolution firsthand—from the callback-heavy, CommonJS-dominated landscape to today’s clean, standards-based development experience. By kashw1n.com.

Modern Node.js (2025) embraces web standards and built-in tools to streamline development, enhance security, and improve performance.

The key points in the article:

  • Module system: ESM is the new standard.
  • Web APIs: Native Fetch API supports timeouts and cancellations; AbortController handles asynchronous task cancellation consistently across APIs like fetch and file reads.
  • Built-in Testing: Node’s native test runner (node –test) replaces external frameworks, offering watch mode and coverage reporting out of the box.
  • Async Patterns: Async/await with error handling and Promise.all() balance performance (parallel operations) and reliability (structured logging).
  • Async iterators manage event streams efficiently.
  • Streams & Workers: Modern stream APIs (pipeline, Web Streams) improve interoperability, while worker threads leverage CPU cores for backgroud tasks without blocking the main loop.

Fewer external dependencies (e.g., axios replaced by Fetch), cleaner syntax (no IIFEs), improved error handling, and seamless integration with web ecosystems like browsers and edge runtimes. These changes reduce complexity, enhance security, and accelerate development cycles. Good read!

FastAPI is a Python web framework based on the Starlette microframework. With deep support for asyncio, FastAPI is indeed very fast. FastAPI also distinguishes itself with features like automatic OpenAPI (OAS) documentation for your API, easy-to-use data validation tools, and more. By Andrew Brookins.

In this tutorial, we’ll walk through the steps necessary to use Redis with FastAPI. We’re going to build IsBitcoinLit, an API that stores Bitcoin sentiment and price averages in Redis Stack using a timeseries data structure, then rolls these averages up for the last three hours.

The learning objectives of this tutorial:

  • Learn how to install aioredis-py and connect to Redis
  • Learn how to integrate aioredis-py with FastAPI
  • Learn how to use Redis to store and query timeseries data
  • Learn how to use Redis as a cache with aioredis-py

Putting all the pieces together, we now have a FastAPI app that can retrieve Bitcoin price and sentiment averages, store the averages in Redis, cache three-hour summary data in Redis, and serve the data to clients. You will also get video and all code samples use in tutorial. Nice one!

Building dynamic user journeys: Your guide to Next.js onboarding with OnboardJS

Categories

Tags react web-development app-development cio

Next.js onboarding flows often become complex due to manual state management, conditional logic, and persistence across sessions. Managing step logic, dynamic navigation, persistence across sessions, and analytics can turn your elegant codebase into a complex web of conditional rendering and state management. By onboardjs.com.

OnboardJS solves a critical pain point for Next.js teams: building maintainable, scalable onboarding flows without compromising the framework’s architecture. Unlike monolithic solutions, it’s a headless engine (from @onboardjs/core) that handles the orchestration layer—step transitions, state persistence, and conditional logic—while keeping your UI components clean and framework-agnostic.

Why managers should care:

  • Time-to-market: Teams spend 30%+ of onboarding effort on boilerplate logic. OnboardJS cuts this by 50%, critical when launching features.
  • Risk reduction: Prevents onboarding bottlenecks (e.g., users stuck in step 2 due to broken state). The condition property lets you skip steps based on real user data (e.g., “skip if email already exists”).
  • Seamless integration: Plugins for PostHog (analytics) and Supabase (user data) auto-sync without adding custom code. Example: When users complete onboarding, OnboardJS immediately triggers a Supabase insert via @onboardjs/supabase-plugin.
  • No framework conflicts: Works with Next.js App Router (unlike legacy libraries that force useEffect hacks). The OnboardingProvider is a pure Client Component—no SSR issues.

OnboardJS turns onboarding from a “user experience chore” into a strategic asset—reducing churn, accelerating adoption, and letting your team ship features faster. For managers: It’s the difference between delayed launches and user retention without adding technical debt. Good read!

Rate limiting for Django websites

Categories

Tags nginx devops infosec devops kubernetes

Rate limiting restricts the number of requests a client can make to your Django website within a specific timeframe. It’s especially useful for blocking malicious bots, crawlers, or brute-force attacks that overwhelm server resources. By Aidas Bendoraitis.

Nginx, often used as a reverse proxy in front of Django applications, provides robust rate-limiting capabilities. Nginx allows you to define rate limit zones, which specify limits on requests based on client IP addresses or other criteria. For example:

  • $binary_remote_addr limits requests per client IP.
  • $server_name applies limits globally across all domains.

You can also configure burst and nodelay settings:

  • burst: Allows a short spike of requests beyond the main limit (e.g., 2 extra requests).
  • nodelay: Processes requests without delays when within burst limits.

If too many requests come in, Nginx returns a 429 error. For instance, limiting list views to 1 request per second with a burst of 2 would block any third request within that timeframe. By implementing rate limiting in Nginx, you can safeguard your Django website from malicious traffic while ensuring smooth performance for real users. Good read!

Securing Kubernetes resources without a VPN

Categories

Tags nginx app-development infosec devops kubernetes

Securing kubernetes resources that you want to expose to only some users externally is often done through IP allowlisting and a VPN. While this is a tried and true method, there are some drawbacks. By Brian Sizemore.

Instead of manual VPN setup, this approach uses OAuth2 Proxy (an open-source tool) paired with Ingress-Nginx (a Kubernetes ingress controller). OAuth2 Proxy authenticates users via their company’s existing identity provider (e.g., Google Workspace, Microsoft) and controls access to resources before they reach Kubernetes. Ingress-Nginx acts as a reverse proxy, redirecting unauthenticated users to the IDP’s login page instead of blocking calls outright.

Here’s how it works:

  • Authentication: When a user tries to access a Kubernetes resource, Ingress-Nginx (the gateway to your cluster) redirects them to OAuth2 Proxy.
  • Validation: OAuth2 Proxy checks if the user is logged into their company’s identity provider (e.g., Google Workspace, Microsoft) using OAuth 2.0 or OpenID Connect.
  • Access Control: If authenticated, the user is granted access. If not, they’re sent to their company’s login page.

By using OAuth2 Proxy, you can simplify access control to internal applications and eliminate the need for a VPN. This approach leverages existing company login credentials and enables fine-grained access control using groups. Good read!

Microsoft entrusts DocumentDB to Linux Foundation

Categories

Tags nosql database cio azure

Microsoft has announced that DocumentDB, their distributed NoSQL database built on PostgreSQL, is joining the Linux Foundation. This represents a significant shift from Microsoft’s traditional approach to database development. DocumentDB was initially created within Microsoft to handle document-oriented workloads (think JSON data) at scale, prioritizing high availability and flexibility. By Bobby Borisov.

Previously, DocumentDB’s roadmap and feature set were dictated by Microsoft’s internal priorities. Now, the Linux Foundation will establish a technical steering committee and working groups. These groups will be composed of representatives from various organizations – including Microsoft, other database vendors, cloud providers (AWS, Azure, Google Cloud), and independent developers. This collaborative approach aims to ensure that DocumentDB evolves in a way that benefits the broader community.

While this move is generally positive, there are potential considerations:

  • Microsoft’s Role: Microsoft will still be involved, but they won’t have sole control over the project’s direction.
  • Community Governance Challenges: Open-source projects can sometimes face challenges in reaching consensus on features and priorities.
  • Potential for Fragmentation: While unlikely given PostgreSQL’s foundation, there’s always a risk of forks or diverging development paths within an open-source project.

Ultimately, Microsoft believes this transition will foster wider adoption, improve stability, and create a more vibrant ecosystem around DocumentDB. It demonstrates a commitment to supporting open standards and community-driven innovation in the database space. Nice one!
