Starting to create the custom components for the application

I’m using Vue 3 with Typescript.

Vue is a popular JavaScript framework for building user interfaces and single-page applications. With the release of Vue 3, there are new features and improvements that make it even more powerful and efficient for developers. One of the great things about Vue is the ability to create custom components, allowing for reusable and modular code that can be easily maintained and scaled.

Getting Started

If you’re new to Vue 3 and Typescript, it’s important to familiarize yourself with the basics of each before diving into creating custom components. Vue 3 introduces the new Composition API, which provides a more flexible and scalable way to organize and reuse code. Typescript adds static typing to JavaScript, helping to catch errors before runtime and improve code quality.

Creating Custom Components

With Vue 3 and Typescript, creating custom components is straightforward. You can define a new component using the defineComponent method, and then specify the properties and methods that the component will have.

For example, let’s say we want to create a custom button component. We can define the component using Typescript interfaces to specify the props and data types, and then use the defineComponent method to create the component with the specified properties and methods.

“`html

{{ buttonText }}

import { defineComponent, PropType } from ‘vue’

interface ButtonProps {
buttonText: string
}

export default defineComponent({
props: {
buttonText: {
type: String as PropType,
required: true
}
},
methods: {
handleClick() {
// Handle button click event
}
}
})

“`

In this example, we define a ButtonProps interface to specify the buttonText prop as a string. We then use the defineComponent method to create the button component with the specified prop and handleClick method to handle the button click event.

Using Custom Components

Once you’ve created a custom component, you can easily use it within your Vue application by importing and registering it in the parent component. For example, if we have a parent component called App.vue, we can import and use the custom button component as follows:

“`html

import { defineComponent } from ‘vue’
import CustomButton from ‘./components/CustomButton.vue’

export default defineComponent({
components: {
CustomButton
}
})

“`

By importing and registering the custom button component, we can now use it within the parent component’s template as <CustomButton buttonText="Click me!" />. This allows for easy reuse and modularity of code, as well as better organization and maintainability of the application.

Conclusion

Creating custom components with Vue 3 and Typescript is a great way to build scalable and maintainable applications. With the new features and improvements in Vue 3, as well as the static typing of Typescript, developers have powerful tools at their disposal to create powerful and efficient custom components for their applications.
