The Software Architects' Newsletter November 2020

A monthly overview of things you need to know as an architect or aspiring architect. [InfoQ]( The Software Architects' Newsletter November 2020 [View in browser]( Our fortieth issue of the Architects' Newsletter again focuses on the topic of "The Modern JavaScript Stack within Enterprise Architectures". We believe this topic will span several phases of the diffusion of the innovation curve. For example, in our most recent [JavaScript and Web Development InfoQ Trends Report (March 2020)]( we placed WebAssembly in the innovation phase of adoption and Node.js, React, and Angular in the late majority phase. We believe that understanding all the emerging patterns, antipatterns, and technologies related to these topics is essential for a software architect. News Running React Applications at the Edge with Cloudflare Workers - Q&A with Josh Larson Josh Larson recently released Flareact, an edge-rendered React [framework built for Cloudflare Workers](. Flareact is inspired by [Next.js](, a React framework that features hybrid static and server rendering. While Next.js optimizes React applications for production deployments, (e.g. pre-rendering, optimized pre-fetching, automatic code-splitting), [Cloudflare Workers]( allows running code on the edge quickly, efficiently, and at scale. Flareact seeks to replicate the advantages brought about by Next while adding the benefits of edge-side rendering and caching. Flareact [currently supports]( file-based page routing, dynamic page paths, API routes, cache policy configuration, and edge-side data-fetching APIs. Angular 11 Released with Improved Developer Experience and Cleanup of Issues Google has released [version 11 of Angular](, its popular single page application (SPA) framework. The [Angular 11]( release focuses on improving the developer experience and finalizing the cleanup of the issue tracker. Following the significant changes made in Angular 9 with the release of [Ivy](, the Angular development team chose to dedicate the following releases to address many of the bugs and concerns that were raised by the community. Mock Service Worker Library Enables Resilient REST and GraphQL API Testing The [Mock Service Worker]( (MSW) API mocking library allows developers to [test web applications without using an actual back-end](, setting up a mocking server, or stubbing native http/https/fetch implementations. MSW mocks both Rest and GraphQL APIs. MSW received the JavaScript Open Source Awards this year. Deno Introduction with Practical Examples This article from [Erisan Olasheni]( presents a series of [tutorials and practical examples]( to help learn Deno and the surrounding ecosystem. Deno is a simple, modern, and secure runtime for JavaScript and TypeScript applications built with the Chromium V8 JavaScript engine and Rust, created to [avoid several pain points and regrets with Node.js](. Deno was originally announced in 2018 and reached 1.0 in 2020, created by the original Node.js founder Ryan Dahl and other [mindful contributors](. Snowpack 2.0 Launches O(1) Build System to Speed up Web Development Early in the year, the [pika]( team released the second major iteration of Snowpack. [Snowpack 2.0]( is described as a build system for the modern web and claims start-up times below 50ms even in large projects. Snowpack 2.0 achieves its speed by eschewing bundles during development. Bundles may still be generated for production. Snowpack 2.0 ships with a set of [Create Snowpack App (CSA)]( starter templates targeting miscellaneous stacks. Case Study Accessible Adaptive Design Systems with Microsoft’s New FAST Framework [Rob Eisenberg](, principal UX architecture and tools lead at Microsoft recently introduced the [FAST Framework]( during the [.NET Community Standup](. [FAST]( allows developers to create their own design system and web component libraries by customizing styles and properties. FAST uses an adaptive color system that meets accessibility contrast requirements, supports color themes, and provides a perceptually uniform UI across different background colors—with little input from developers. FAST comes with a premade [Fluent UI component library](. Microsoft explained the motivation behind FAST with a series of questions that summarize the key alleged benefits of the FAST framework: "Have you ever needed a reusable set of UI components that you could drop into your app and have an amazing experience? […] Have you ever needed to create your own components, and share them across your company, including across groups that use different, incompatible front-end frameworks? […] Have you ever needed to implement a branded experience or a design language like Microsoft's Fluent UI or Google's Material Design? […] Have you ever wanted to improve your app's startup time, render speed, or memory consumption? […] Have you ever wanted to […] build your […] app on a native web foundation that's immune to the shifting sands of the modern JavaScript front-end landscape?" FAST comes as a collection of JavaScript packages, including [fast-element](, fast-foundation, [fast-components](, and fast-colors. Developers and designers may define their own design system, understood in a FAST context as a collection of properties ([CSS variables]() and values that inform the visual design language of the components. A FAST design system is implemented by a [DesignSystemProvider]( custom element that lists the custom properties to be consumed by component stylesheets. FAST components' documentation is thorough and provides examples of integrations of the component library with Webpack and miscellaneous frameworks, including, but not limited to, Angular, Aurelia, React, Blazor, and [ASP.NET](. Developers can review the [FAST component library]( online with the provided component explorer.
