style: run prettier on all files

[leonardodino]

issue

I've noticed that changing and committing files introduced format related changes.

solution

format all files to conform to the prettier config defined in package.json.

next steps

I think prettier rules should be checked into a .prettierrc file,
and should run on all files before the initial commit.
