Unlock the Power of Dynamic Components in Vue.js
What Are Dynamic Components?
Imagine being able to switch seamlessly between different components in your Vue.js application without having to create routes or navigate through the DOM. This is exactly what dynamic components offer – a flexible and efficient way to render different components based on certain conditions or user interactions.
Why Are Dynamic Components Important?
When designing your user interface, you want to be able to show or hide nested components based on the application state. Dynamic components provide a platform to do just that, saving you from writing unnecessary code and ensuring your presentation remains clean and unambiguous.
Getting Started
To follow along with the examples in this article, you’ll need:
- Node.js installed (verify by running
node -vin your terminal) - A code editor (preferably VS Code)
- A Vue.js project
If you don’t have a Vue.js project set up, you can scaffold a new one using the official Vue project scaffolding tool, create-vue.
Dynamic Components Syntax
Vue offers a special inbuilt component called <component> that accepts a :is directive, specifying the name or definition of the component to be rendered. This allows you to dynamically switch between components without using routing.
Dynamic Components Demo
Let’s create two dynamic components and switch between them without using routing. Create two new components, Test_1 and Test_2, and register them in your App.vue file. Then, use the <component/> to dynamically render the default component.
Persisting Data When Switching Between Dynamic Components
When switching between dynamic components, you want to ensure that your component state stays intact. Vue provides a keep-alive element that allows you to store data values per state. This means that when you switch back to a component, you’ll return to the exact state you left it in.
Taking It to the Next Level
By combining dynamic components with keep-alive, you can build powerful user interfaces that adapt to your users’ needs. Whether you’re building a complex dashboard or a simple form, dynamic components provide a flexible and efficient way to render different components based on certain conditions or user interactions.
