Npm comes with a neat tool called npx that lets you directly execute packages from the npm registry. It temporarily downloads it behind the scene and won’t pollute your local or global npm environment.

I’ve used Google Fonts in prototypes and in 10M+ MAU products. It’s incredibly easy to get started with and provides an amazing font discovery.

…and other things I’ve heard regarding Hybrid App development. Let’s talk about the elephant in the room: Performance. Let me just show you how fast and smooth Hybrid apps can be based on this footage of my last work: JustWatch, a streaming search engine with 12M monthly active users. It’s been recorded on a OnePlus 6 (May 2018). “Hybrid Apps will never be faster than native” Yes, this is true.

MARCH 2020 UPDATE: The new Firebase JS SDK Alpha makes your bundle up to 80% smaller! It now fully adopts tree-shaking and lets you import only what you truly need. In a lot of tutorials I came across the comfortable solution of just adding import * as firebase from ‘firebase’ for your firebase import. As it turns out, there are 4 modular packages for Firebase.
