Not all props are created equal.
Some of them are necessary for the component to work correctly.
Here is an example How to make required props in vuejs:
export default {
name: 'Camera',
props: {
name: {
type: String,
required: true,
},
img: {
type: String,
},
rating: {
type: Number,
},
}
}
Here we set our name prop to be required by adding required: true to its prop definition.
By default props are not required, so we don't need to touch the other ones. We could add required: false if we wanted to.
Example 2:
Vue.component('my-component', {
props: {
// Basic type check (`null` and `undefined` values will pass any type validation)
propA: Number,
// Multiple possible types
propB: [String, Number],
// Required string
propC: {
type: String,
required: true
},
// Number with a default value
propD: {
type: Number,
default: 100
},
// Object with a default value
propE: {
type: Object,
// Object or array defaults must be returned from
// a factory function
default: function () {
return { message: 'hello' }
}
},
// Custom validator function
propF: {
validator: function (value) {
// The value must match one of these strings
return ['success', 'warning', 'danger'].indexOf(value) !== -1
}
}
}
})
