Add ability to format on save

[michaelryancaputo]

Is your feature request related to a problem? Please describe.
Would love to be able to set this up to run on save the same way Prettier does.

Describe the solution you'd like
As a user I should have the option to enable a 'format on save' feature instead of invoking it through the command panel.

I would really like this as well. Unfortunately, as far as I know, VSCode doesn't have a good way to prioritize plugin order. When I set it up to format on save, it ended up preventing prettier from formatting on save. In other words, it appears that you can only have one formatter running for any one file type at any given time. If you know otherwise please let me know and I'll take another stab at it. Either way, I'll do a bit more research. Maybe it is possible now.

I wonder if prettier could use this as a plug-in.

[johnuphoff]

I also considered that as a possibility. I'll look into this again as well.

It looks like Prettier now has a plugin API in beta that would allow us to contribute a compatible styled-components parser. The only question I have is whether or not it will allow multiple parsers running simultaneously.

You can try eslint-plugin-better-styled-components which has a rule better-styled-components/sort-declarations-alphabetically

Seemed to work well on my code base.
