I started this project, "DeckDeckGo", in october 2018. I had to prepare a talk about Ionic v4 and Web Components and I noticed that I wasn't using the technology I was about to display.
As any engineer, what did I do in such situation? I created quickly a library using StencilJS to write my presentation only with Web Components.
After the presentation I did continue to "work" on my spare time on the project as it is for me a way to learn new technologies and concept.
Meanwhile Nicolas Mattia joined the project and together we decided to have even more fun by turning it into a fully web open source editor for presentations.
