React Native Vector Icons
Customizable Icons for React Native with full styling
Perfect for buttons, logos and nav/tab bars. Easy to extend, style and integrate into your project. If you want to use any of the bundled icons, you need to add the icon fonts to your Xcode project. For each platform (iOS/Android/Windows) you plan to use, follow one of the options for the corresponding platform. Upgrading this package often requires the font files linked to your projects to be updated as well. If the automatic linking works for you, running this again should update the fonts. You can either use one of the bundled icons supported or roll your own custom font. Since Icon builds on top of the Text component, most style properties will work as expected, you might find it useful to play around with background color, border width, border color, border radius, padding, margin, color, font size, etc. -

Typed.js
A JavaScript typing animation library
Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set. Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page. You can pause in the middle of a string for a given amount of time by including an escape character. CSS animations are built upon initialization in JavaScript. But, you can customize them at your will!
