React-typing-animation

A fully-featured typing animation in React that supports any valid JSX.

Motivation

There were other JS typing animations that existed when I created this, but they were all lacking in robust features. This component aims to support all of the following features:

✅ Type text from any valid JSX

✅ Preserve DOM structure/styling

✅ Change typing speed anywhere in tree

✅ Add a delay anywhere in tree

✅ Backspace animation

✅ Reset lines / full tree

✅ Loop functionality

✅ No dependencies (CSS or JS)
