Intro
Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.
Input
foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());
Output
foo(
reallyLongArg(),
omgSoManyParameters(),
IShouldRefactorThis(),
isThereSeriouslyAnotherOne()
);
Prettier can be run in your editor on-save, in a pre-commit hook, or in CI environments to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!
