Web Components: The Secret Ingredient Helping Power The Web

As a web developer, you may or may not have tried Web Components – but as a web user, you almost certainly have. Adoption has quietly taken off. Millions of domains making up several percent of all page loads on the web use Web Components. This session will look at where Web Components can help you, like with interoperability, reuse and design systems. Learn how Salesforce uses Lightning Web Components to power their ecosystem of 5 million developers.

I notice there is still a lot of confusion about what "web components" actually means. Is it a synonym for "custom elements" or a set of APIs? A lot of people use "web components" and "custom elements" interchangeably. Some even say "custom components". This video is no exception.

First kill internet explorer, then this will really take off for Enterprise software.
I also hear that Safari is just as bad as IE at keeping up with web components.

every time I see a chrome video that mentions native I always leave a comment saying I've been using lit-element for years now and it's literally one of the best tools I use. the biggest upside is page performance and ease of development

lit comes removes **all** of the run-time cost that you'd get with frameworks like react, lit's organization model and render model is nearly identical to react (but again, without the runtime performance cost you'd get from react), it makes it a lot easier to debug when you use the inspect tool (because your component names show up in the elements view), it makes the browser profiling tools a lot easier to work with because the profiler will actually display which components and which function/methods are running (unlike react where you have manually track down which subtree of html elements is a component), and lit still works in such a way where you can still take use of what ever state/store library you prefer to use

tl;dr its a much lighter-weight version of react without the developer pain points

Still don't understand what web components are. Started off strong, then all downhill from the Salesforce example

I wanted to learn Web components and Polymer but damn there is a very very poor community for this only few videos are available on YouTube for web components as well as for Polymer all tutorials made on 2014.
It's an impressive technologies to learn that's why i hope that Google take care of this and publish tutorials for it.
And thanks google for Angular Elements Which allow the developer to create Web Components more easly and faster.

LitElement is product of the polymer they were ahead of the

Can you please tell me how to use the decorator syntax, the property property in conjunction with the redax?
I want use @property({type: Array}) stages instead of
static get properties() {
return {
stages: {type: Array}
}
but this property defined in _stateChanged(state) {
this. = state.reducer.stages
}
so it posible?

Will Flutter-web (hummingbird) output web components?

Read Blog post about LitElement and webcomponents. After this I saw Google photos is an pwa now. Does someone know what Framework/Library Google use?

Huge success huge success. Sorry, but where??

Unfortunatelly as complexity grows the less attractive Webcomponents are. Using it with multiple nested slots is making performance a joke.

How do we create a CSS Framework on Web Components? And I mean CSS only, no components suggestion please

[Loppy]

Why would I use React + a web component when I can just use a React component?
