lit VS TypeScript

That is the reason why I experiment with the TiniJS framework for a while. It is a collection of tools for developing web/desktop/mobile apps using the native Web Component technology, based on the Lit library. Thank you the Lit team for creating a great tool assists us working with standard Web Component easier.

actually, looking at it (https://lit.dev/), i do exactly that.

I also define a `render()` and extend my own parent, which does a `replaceChildren()` with the render. And, strangely, I also call the processor `html`

I'll still stick with mine however, my 'framework' is half-page of code. I dislike dependencies greatly. I'd need to be saving thousand+ lines at least.

Here, I don't want a build system to make a website; that's mad. So I don't want lit. I want the 5 lines it takes to invoke a dom parser, and the 5 lines it takes do define a webcomp parent.

I rather like https://lit.dev/ for web components so far.

For the reactivity stuff, you might want to read https://frontendmasters.com/blog/vanilla-javascript-reactivi... - it shows a bunch of no-library-required patterns that, while in a number of cases I'd much rather use a library myself, all seems at least -basically- reasonable to me and will probably be far more comprehensible to you than whatever I'd reach for, and frameworks are always much more pleasant to approach after you've already done a bunch of stuff by banging rocks together first.

I work on Lit, which I would hesitate to call a framework, but gives a framework-like DX for building web components, while trying to keep opinions to a minimum and lock-in as low as possible.

It's got reactivity, declarative templates, great performance, SSR, TypeScript support, native CSS encapsulation, context, tasks, and more.

It's used to build Material Design, settings and devtools UIs for Chrome, some UI for Firefox, Reddit, Photoshop Web...

https://lit.dev if you're interested.

I am more a fan of the augmented style because it doesn't entrap you in dev lock-in to platforms.

The problem with frameworks, especially web frameworks, is they reimplement many items that are standard now (shadowdom, components, storage, templating, base libraries, class/async, network/realtime etc).

If you like the component style of other frameworks but want to use Web Components, Google Lit is quite nice.

Google Lit is like a combination of HTML Web Components and React/Vue style components. The great part is it is build on Web Components underneath.

From the comments I see here, it seems like people expect the Webcomponents API to be a complete replacement for a JS framework. The thing is, our frameworks should start making use of modern web APIs, so the frameworks will have to do less themselves, so can be smaller. Lit [0] for example is doing this. Using Lit is very similar to using React. Some things work different, and you have to get used to some web component specific things, but once you get it, I think it's way more pleasant to work with than React. It feels more natural, native, less framework-specific.

For state management, I created LitState [1], a tiny library (really only 258 lines), which integrates nicely with Lit, and which makes state management between multiple components very easy. It's much easier than the Redux/flux workflows found in React.

So my experience with this is that it's much nicer to work with, and that the libraries are way smaller.

Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.
