Can I set a default value by accessing route parameters through props?

Is there a way to display the ID from my $route if a prop is empty using Vue.js? Here's what I tried:

props: {
  name: {
    type: String,
    required: true,
    default: 'user ID: ' + this.$route.params.user_id,
  }
}

I keep getting an error that "this" is undefined. Any suggestions on how to access route params from props in Vue.js?

Answer №1

If you want to set a default value for a prop in Vue.js, you can actually pass a function as the default property:

props: {
  name: {
    type: String,
    required: true,
    default() {
      return 'user ID: ' + this.$route.params.user_id;
    }
  }
}
