What are the different kinds of properties that can be used in Vue.js

When working with Javascript, I can create arrays that hold different types of data elements like:

var ex = ['name', 12, true];
console.log(ex);

In Vue JS, when defining props for a component within a single file template, I have the option to declare them in the <script></script> section as follows:

export default{
props: ['myprop']
}

Alternatively, I can specify the props as an object with type validation like:

export default{
  props: {
    myprop: String
  }
}

Now, the question arises - in Vue, if I list an array of types such as myprop: [String, Array], how can I validate the content of the array at the props level?

For example, is there a way to ensure that any value passed into the prop matches the pattern of a string, number, boolean, and a count of 3?

So, if I receive data in the form of [true, 12, 'name'], it would be considered invalid. However, if the data aligns with the structure of the 'ex' array, then it would be deemed valid.

Answer №1

It seems like you're looking to implement a custom property validation function. Here's an example code snippet:

props: {
  myprop: {
    type: Array,
    validator: value => {
       return /* define your own validation logic here */;
    }
  }
}

The 'type' property provides basic type validation, while the custom validator gives you the flexibility to define more specific criteria for valid properties in your component.
