Vue allows a child component to share a method with its parent component

Which approach do you believe is more effective among the options below?

[ 1 ] Opting to utilize $emit for exposing methods from child components to parent components

$emit('updateAPI',  exposeAPI({ childMethod: this.childMethod }))

OR

[ 2 ] Utilizing $refs in the parent component to access methods of the child component

this.$refs.childComponent.childMethod() 

Answer №1

Regarding $refs, the documentation states that they are only populated after the component has been rendered and are not reactive. They should be used as a last resort for direct child manipulation, and it is recommended to avoid accessing $refs from within templates or computed properties.

"$refs are only populated after the component has been rendered, and they are not reactive. It is only meant as an escape hatch for direct child manipulation - you should avoid accessing $refs from within templates or computed properties."

As for callbacks, I do not have specific information about their disadvantages. However, there is a helpful example in the script section of this Quasar Framework component. In this example, the parent component emits a function called reset which the child component can then dispatch. This approach seems preferable in such cases.
