Streaming HTML – Asynchronous DOM Updates without JavaScript

Web applications provide the best user experience when pages load quickly and display additional data as it becomes available. Developers typically use JavaScript to load data asynchronously, but this adds complexity when compared to server-side rendering. We review a technique that uses the Shadow DOM with HTTP streaming to load pages quickly and display data asynchronously without JavaScript.

How to Sustain Quality and Velocity in a JavaScript or TypeScript Project?

The JavaScript language and its ever-changing ecosystem of packages and practices can make codebases quickly become hard to maintain. The resulting loss of development velocity and/or code quality can be prevented without rewriting everything from scratch, nor pausing the development of new features. In this article, we have analyzed a few best practices to help avoid that.

Interactive Microservices as an Alternative to Micro Front-Ends for Modularizing the UI Layer

While microservices architectures are well established for the back-ends of software systems, the same cannot be said for front-ends. Interactive microservices are based on a new type of web API that Qworum defines, the multi-phase web API, where the endpoint calls may involve more than one request-response pair, also called a phase.

Separation of Concerns in Node.js

In Node.js you can structure your code however you want. There is no "correct way". You have the option of writing all of your code in a single app.js file or creating multiple files and placing them in different folders. Most developers, however, would recommend structuring your projects by grouping related data together rather than having it all together.

Turning a Node.js Monolith into a Monorepo without Disrupting the Team

Splitting monoliths into services creates complexity in maintaining multiple repositories (one per service) with separate (yet interdependent) build processes and versioning history. Monorepos have become a popular solution to reduce that complexity.

Designing Secure Tenant Isolation in Python for Serverless Apps

Software as a Service (SaaS) has become a very common way to deliver software today. While providing the benefits of easy access to users without the overhead of having to manage the operations themselves, this flips the paradigm and places the responsibility on software providers for maintaining ironclad SLAs, as well as all of the security and data privacy requirements.

Deep Dive into Reactive Programming with RxJS

One of the most challenging aspects of developing any user-facing application is handling asynchronous actions such as user input and API requests cleanly and robustly. RxJS helps developers author declarative code for handling side effects and asynchronous actions with continuous data streams and subscriptions.

Compiled, Typed, Ruby-Inspired Crystal Language is Ready for Production - Q&A with Beta Ziliani

The Crystal language is ready for production, 12 years after inception. Crystal is compiled for performance, typed for safety, and Ruby-like for productivity. Due to the strong type inference, developers need only sparse type annotations. We interviewed the head of the Crystal team on the language tradeoffs, the present features and the language roadmap.
