This package will automatically look for all the SVGs in your codebase, package them up together as a sprite, and insert that sprite in your DOM.
meteor add utilities:compile-svg
The package also provides a helper to easily use SVG images (note the triple {{{...}}} tag):
{{{getSVG filename}}}
(Note: filename is the svg file's name without its extension)
Loading all your SVGs in a single sprite means they don't take up multiple browser requests, and including them right in the DOM means they're styleable using CSS. See this article for more info.
