Motivation In the last year(2018), I and my friend heliocorreia talk about making the personal website and make a post in it. But, I different from him didn’t want to create a blog system for posting. I thought, why not use Medium with as my publication platform and I build a script to migrate from Medium to Markdown?

Do you need use Web Components in your application? No, you don’t need it. I’m totally against the hype. You should use if only you need. I see some advantages to use if you really need it. For example componentization and your advantages, very small final bundle size, etc. In the article I talk about a project we(My team) started at globo.com. The project was build Stories like Instagram. We use ZuckJS for a POC(proof of concept) but we need to customize a lot this lib. It was a very expensive cost to customize, so I start writing a Vanilla Javascript Lib and after I transform it to Web Components. You can see here the vanilla version — branch master.
