Backbone.js VS Svelte

Got it thanks for the context.

I've read the web app and it seems to me it is just https://backbonejs.org/ re-written in Typescript and allows JSX.

I'm very certain Typescript and JSX will have improved the DX for Backbone like apps, but it doesn't address all of the other issues that teams had with Backbone.

e.g. Cyclical event propagation, state stored in the DOM (i.e. appendChild is error prone in large code bases), etc.

What we see, a decade ago, are that many of the "popular" libraries, frameworks, and methods, not surprisingly, have gone by the wayside, a lot that have remained in current code as difficult-to-removemodernize legacy cruft (Bower, Gulp, Grunt, Backbone, Angular 1, ...), and then we have the small minority that are still here. Some that remain have had their utility lessened/questioned by platform and language improvements (jQuery, lodash, ...), but very, very few exist that are the same now as they were then. Another fun historical reference: issue #118 of "JavaScript Weekly" (February 22, 2013) includes a first link out to asm.js.

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. site Backbone.js *Backbone.js gives structure to web applications by providing models with key-value binding and custom events…*backbonejs.org

The ajax request is made via a call to Backbone.sync() of Backbone.js, which ultimately calls jquery's $.ajax(). I haven't changed anything about how the call is made... just upgraded cordova.

my gf said it was the best. she uses backbone.js she good dev

Backbone.js

A lot of SPA frameworks and libraries also were developed. We can find out some of its on the internet. They are AngularJs, Reactjs, BackboneJs, DurandalJs,.. and a lot of third party components to make the Javascript coding more easy like RequireJs, Amplifyjs, BreezeJs...

As the internet became faster, and more reliable, and as browsers unified into “evergreen” releases, developers accepted JSON to be the only shape of data needed to travel on wires. A few years back I posted a question of which was a better framework: serving fully processed HTML scripts over Ajax, or only JSON that would be populated on client-side. See, back then, populating JSON was hand crafted, before Knockout, before Backbone, and few other players I don’t recall. The thing you could use back then was Mustache-like, which -by the way- still is a favorite of mine when venturing outside of SPA zone.

React has introduced measures like batching state updates, background concurrent rendering and memoization to tackle this. My opinion is that the best way to solve the problem is by improving their reactivity model. The app needs to be able to track the code that should be re-run on updating a given state variable and specifically update the UI corresponding to this update. Tools like solid.js and svelte work in this manner. It also eliminates the need for a virtual DOM and diffing.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Svelte is a powerful web framework that offers a fresh approach to building web applications. Its simplicity, reactivity model, and built-in features make it an excellent choice for developers looking to create efficient and maintainable applications. By following this guide, you should now have a good understanding of how to get started with Svelte and build your first components, routes, and transitions. You can read more about svelte on the official Svelte website.

Use .NET features (especially dotnet watch) as a setup for a client-side Svelte application, starting from a simple C# console app.

Volar originally was Vue3's language support tool for VScode (I don't know about other editors). By today, volar has become a language indipendent framework to create language tools. It might still be a bit early for the dev with skill issues like me to use it and build some tools, but astro and svelte already use Volar to create their language tools.
