Thanks for this PR. Unfortunately, this is not the right place for the fix. Can you move it here: https://github.com/smooth-code/svgr/blob/master/src/index.js#L31.

Also by the way, we should modify line 32:

return {  componentName, ...state }

So the user can specify a componentName using rawConvert method.

Can you also add a test targetting rawConvert and verifying that it works?

But I thought you said you only want to change the variable name in the code?

We should add Svg in front of numbers but only in component name!

I meant not in file name. In case of svgr -d lib src
