Add support for .svgrrc

[gregberge]

As mentioned in #81 by @lifeiscontent, SVGR should have its own .svgrrc in order to be able to specify desired options.

I like the way Prettier is doing it:

• Supporting multiple formats
• Add three methods in API to interact with configuration: resolveConfig, resolveConfigFile and clearConfigCache

cosmiconfig is the good candidate to do it.

To resume :

• Load configuration from .svgrrc and other default from cosmiconfig
• Expose resolveConfig, resolveConfigFile and clearConfigCache

@neoziro cool, thanks for pulling the issues together. Is anyone currently on track to do this? I might be able to take a stab at this sometime this week. Also super stoked to see svgr in create-react-app!

[gregberge]

Yeah I am very happy that it is now in create-react-app. Next week I am going to talk about it at React Europe.

About the issue, you can take it if you want :)

@neoziro that's awesome, you should definitely have a slide saying, now that you've seen all this awesomeness, and you're not sure how to set it up, don't worry, because create-react-app 2.0 will have it included.

I think that will encourage a lot of people and get some excitement around it for the less technical users.

[gregberge]

Yes you are right!

[lifeiscontent]

@neoziro should I work out of the master branch?

[gregberge]

@lifeiscontent no on next branch

[lifeiscontent]

@neoziro sorry for the slow replies, it seems the snapshot tests are out of date, should I update them with -u or are they just not passing on next?

[gregberge]

Yes update them if they are not OK.

[lifeiscontent]

@neoziro should we close this? I forgot to add it to the commit message.

[gregberge]

No I close it when I release the new version.

[gregberge]

v2 is published 🎉

[lifeiscontent]

Nice!
