What is vue-class-component?
The vue-class-component package is a library that allows you to define Vue components using ES2015/ES6 class syntax. It provides a more structured and object-oriented approach to building Vue components, making it easier to manage and maintain complex applications.
What are vue-class-component's main functionalities?
Class-based Component Definition
This feature allows you to define Vue components using ES6 class syntax. The @Component decorator is used to mark a class as a Vue component.
import { Vue, Component } from 'vue-class-component';
@Component
class MyComponent extends Vue {
message: string = 'Hello, world!';
greet() {
console.log(this.message);
}
}
Lifecycle Hooks
You can define lifecycle hooks as methods within the class. This example shows how to use the created lifecycle hook.
import { Vue, Component } from 'vue-class-component';
@Component
class MyComponent extends Vue {
created() {
console.log('Component created');
}
}
Computed Properties
Computed properties can be defined as getter methods within the class. This example demonstrates a computed property that concatenates first and last names.
import { Vue, Component } from 'vue-class-component';
@Component
class MyComponent extends Vue {
firstName: string = 'John';
lastName: string = 'Doe';
get fullName() {
return `${this.firstName} ${this.lastName}`;
}
}
Watchers
Watchers can be defined using the @Watch decorator. This example shows how to watch for changes to the 'message' property.
import { Vue, Component, Watch } from 'vue-class-component';
@Component
class MyComponent extends Vue {
message: string = 'Hello';
@Watch('message')
onMessageChanged(newValue: string, oldValue: string) {
console.log(`Message changed from ${oldValue} to ${newValue}`);
}
}
