`yield-star-spacing`

Rule Details

This rule enforces spacing around the * in yield* expressions.

The rule takes one option, an object, which has two keys before and after having boolean values true or false.

before enforces spacing between the yield and the *. If true, a space is required, otherwise spaces are disallowed.
after enforces spacing between the * and the argument. If it is true, a space is required, otherwise spaces are disallowed.

The default is {"before": false, "after": true}.

json

"yield-star-spacing": ["error", {"before": true, "after": false}]

The option also has a string shorthand:

json

"yield-star-spacing": ["error", "after"]

Examples of correct code for this rule with the default "after" option:

/* eslint @stylistic/yield-star-spacing: ["error", "after"] */

function* generator() {
  yield* other();
}

If your project will not be using generators or you are not concerned with spacing consistency, you do not need this rule.
