PickOptional¶

Overview¶

Type PickOptional¶

Use PickOptional to pick properties of a type T and make them optional. This is useful when picking superclass options that you want to expose in a subclass API. (Careful if you pick a required superclass option and make it optional - you'll need to provide a default!) It makes life a little easier because you have to fiddle with fewer '<' and '>' characters, and PickOptional makes a little more sense than Pick<Partial> in the context of options.

Example: type MyClassOptions = PickOptional<PathOptions, 'stroke', 'lineWidth'>; Result:
