Rule name: computed-property-getters

Enforce the consistent use of getters in computed properties

Computed properties may be created with or without a get method. This rule ensures that the choice is consistent.

Options

This rule takes a single string option

String option:

• "always-with-setter" (default) getters are required when computed property has a setter
• "always" getters are required in computed properties
• "never" getters are never allowed in computed properties
