Vue JS Interview Questions and Answers

Question - How do you resolve circular dependencies between components?

Answer -

In complex applications, vue components will actually be each other’s descendent and ancestor in the render tree.

Let's say componentA and componentB included in their respective templates which makes circular dependency,

//ComponentA
 
//ComponentB
 
This can be solved by either registering(or wait until) the child component in beforeCreate hook or using webpack's asynchronous import while registering the component,

Solution1:

beforeCreate: function () {
 this.$options.components.componentB = require('./component-b.vue').default
}
Solution2:

components: {
 componentB: () => import('./component-b.vue')
}
