How can I use PropTypes in Vue.js for advanced scenarios?
In Vue.js, PropTypes can be used to validate props in components. For advanced usage, you can define custom validators.
Can you give me an example of a custom validator?
Sure! You can create a custom validator like this: validator: value => typeof value === 'string' && value.length > 0
.
What if I want to validate an array of objects?
You can use a custom validator that checks each object in the array. For example, validator: value => Array.isArray(value) && value.every(item => typeof item === 'object')
.
Are there any performance considerations I should be aware of?
Yes, extensive prop validation can impact performance, especially in large applications. Use it judiciously.
