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!
