If not SPAs, what?

Tom MacWright shared some concerns for SPAs place in the modern web and followed it up with a post sharing suggestions to use instead.

The SPA pattern (Single-Page Apps), I tried to define, was about the React model, which also covers, to a large extent, the model of Vue, Angular, and other frontend frameworks.

Like any critique, it begs for a prescription and I didn’t give one, other than gesturing toward server-side frameworks like Rails and Django. But I think there are some trends starting to form. I had queued up some time to really dive into the frameworks, but things like walking in parks have taken priority, so here’s just a grand tour.


Hyperapp – the tiny framework for building web interfaces

Hyperapp claims to be twice as fast as React, weighs in at 1.8KB, and renders interactively in ~10ms.

Hyperapp is a modern VDOM engine, state management solution, and application design pattern all-in-one. once you learn to use it, there’ll be no end to what you can do.

A UI framework that runs (almost) entirely in Web Workers

Tobias Uhlig:

Neo is based on top of ES8 and uses the latest ES features as long as they can run directly inside the browser. This is one of the major design goals: the dev mode can run inside a browser without needing any JS related builds or transpilations. Instead of using any kind of templates, persistent JSON structures are in place. The combinations of these concepts lead to a pretty amazing performance and adds new possibilities for scaling to the UI area.

I haven’t seen any benchmarks or examples where using Neo produces extreme performance, but conceptually it makes sense that moving computationally expensive things to background threads would keep your UI thread snappy.


The cost of JavaScript frameworks

We all know our users pay a cost when we push our JS framework in to their browser. Now, thanks to Tim Kadlec doing the yeoman’s work of crunching the numbers, we can approximate just how much that cost really is.

There is no faster (pun intended) way to slow down a site than to use a bunch of JavaScript. The thing about JavaScript is you end up paying a performance tax no less than four times:

  1. The cost of downloading the file on the network
  2. The cost of parsing and compiling the uncompressed file once downloaded
  3. The cost of executing the JavaScript
  4. The memory cost

Thanks to HTTP Archive, we can figure that out.

I’m pretty happy with how sites using jQuery size up. Granted, it’s not really a UI framework like the others are, but you have to imagine that many of those sites also use jQuery UI and their overall cost still compares well to the more modern solutions.

Developing a mental framework

The quality of your thinking depends on your mental framework. To become a better thinker you need to have an understanding of this mental framework and how you view the world. But, what exactly is a mental framework? How have we all been programmed throughout our lives? In what ways have you been programed that you like, don’t like, or want to change? Join us as we explore and examine the key components of developing a mental framework.

Blitz.js — a Rails-like framework for full-stack React apps without an API

Brandon Bayer:

The central thesis is that most apps don’t need a REST or GraphQL API. Blitz brings back the simplicity of server rendered frameworks like Ruby on Rails while preserving everything we love about React.

Additionally, Blitz is bringing other Rails goodness that’s missing in the React ecosystem like file structure and routing conventions, a really nice console REPL, intelligent code-scaffolding, and a fine-tuned out-of-the-box setup with Prettier, Typescript, ESlint, Jest, Cypress, etc.

The framework ‘wars’ continue right alongside the monolith-vs-microservices debate. For more on the principles behind Blitz, check out the manifesto.


Fiber – an Express inspired web framework for gophers

I know the Go community isn’t one for frameworks, but as a long time framework user myself, I’ve never quite understood the resistance. Fiber doesn’t hide the ball. It comes right out and says “this is a web framework written in Go”. Here’s the philosophy behind that:

New gophers that make the switch from Node.js to Go are dealing with a learning curve before they can start building their web applications or microservices. Fiber, as a web framework, was created with the idea of minimalism and follow UNIX way, so that new gophers can quickly enter the world of Go with a warm and trusted welcome.

Fiber is inspired by Express, the most popular web framework on the Internet. We combined the ease of Express and raw performance of Go. If you have ever implemented a web application on Node.js (using Express or similar), then many methods and principles will seem very common to you.

I’ve spent 5 years writing a JavaScript framework on my own

Typescene is a robust front end library written in TypeScript: strongly typed, no dependencies, no nonsense. It’s really great for desktop-like (or mobile) applications, not so great for blogs and other content. It isn’t backed by some major corporation, not even a startup, but it’s been built by me: one developer on a mission to build a no-nonsense dependency-less framework

The author’s journey is noteworthy, but if you’re mostly wanting to know if this particular framework speaks to you, jump directly to its list of goals.

Flutter for web

Flutter for web is a code-compatible implementation of Flutter that is rendered using standards-based web technologies: HTML, CSS and JavaScript. With Flutter for web, you can compile existing Flutter code written in Dart into a client experience that can be embedded in the browser and deployed to any web server. You can use all the features of Flutter, and you don’t need a browser plug-in.

This means Flutter is now on mobile, web, desktop, and embedded systems. What surprises me is how dedicated to Dart Google seems to be, despite community malaise and the success of TypeScript.

Svelte 3: rethinking reactivity

After several months of being just days away, we are over the moon to announce the stable release of Svelte 3. This is a huge release representing hundreds of hours of work by many people in the Svelte community, including invaluable feedback from beta testers who have helped shape the design every step of the way.

Lots of folks (myself included) have been eagerly awaiting this release after Rich teed it up on The Changelog #332. We’d love to hear your first impressions!

Deskgap — build cross-platform desktop apps with web technologies

Stop me if you’ve heard this one before…the difference is DeskGap leverages the operating system‘s webview instead of baking a browser in with it (like Electron).

DeskGap is a framework for building cross-platform desktop apps with web technologies (JavaScript, HTML and CSS).

To enable native capabilities while keeping the size down, DeskGap bundles a Node.js runtime and leaves the HTML rendering to the operating system‘s webview.

A UI framework without the framework

Jerod and Adam talked with Rich Harris –a JavaScript Journalist on The New York Times Investigations team– about his magical disappearing UI framework called Svelte. We compare and contrast Svelte to React, how the framework is embedded in a component, build time vs. run time, scoping CSS to components, and CSS in JavaScript. Rich also shares where Svelte v3 is heading and the details on Sapper, a framework for building extremely high-performance progressive web apps, powered by Svelte.
