如何更漂亮地打破所有联合类型？

Question

I want this:

type SomeType = Variant1 | Variant2

to always format into this:

type SomeType =
  | Variant1 
  | Variant2

No matter whether it overflows the specified column width or not.

Answer 1

If you need that degree of control over formatting you're likely not the target audience for Prettier because such things are intentionally not configurable in it. See Prettier's option philosophy . That said, you still can achieve what you want by creating a fork or a plugin.
