You can get access to a good default set of iconography by adding the Material Icon web font to your application. Clocking in at 48 kb in size, this is a very lightweight library.
- For icon support, import the font in index.html:
src/index.html<head> ... <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet"></head>
Discover and search through the icons on https://www.google.com/design/icons/.
