If you want to load it from a file, you may try to use React-inlinesvg - that's pretty simple and straight-forward.

import SVG from 'react-inlinesvg';

<SVG
  src="/path/to/myfile.svg"
  preloader={<Loader />}
  onLoad={(src) => {
    myOnLoadHandler(src);
  }}

  Here's some optional content for browsers that don't support XHR or inline
  SVGs. You can use other React components here too. Here, I'll show you.
  <img src="/path/to/myfile.png" />
</SVG>
