Vue.js 3.0 Style Guide
Vue 3.0 introduced a number of features and improvements to help developers create web applications more efficiently and with more capabilities. Here is a list of standard features and improvements in Vue 3.0:
1. Composition API: The Composition API is an advanced feature that allows developers to use a function-based approach for creating components. It's an addition to the current Options API and can provide better organization and reuse of component logic.
2. Improved Performance: Vue 3 has significant performance improvements thanks to its rewritten Virtual DOM, static tree hoisting, and patch flagging. These improvements make Vue 3 faster and use less memory.
3. Fragments: In Vue 2, each component needed to have one root element. In Vue 3, this is no longer the case �C you can have multiple root elements thanks to Fragments.
4. Portals: Portals provide a way to render parts of a component outside the component��s DOM tree. This can be useful for things like modals or tooltips.
5. Suspense: Suspense components allow for better handling of async operations, such as fetching data from an API before rendering a component.
6. Improved TypeScript Support: Vue 3 has better TypeScript integration out of the box, making it easier for TypeScript users to develop Vue applications.
7. Custom Renderer API: Vue 3 exposes a lower-level Custom Renderer API, inspired by React��s custom renderer - this is what powers Vue Native.
8. Multiple v-models: Vue 3 allows a component to have multiple v-models, which can help when you need to track multiple values with two-way data binding.
9. Teleport: Teleport (formerly known as Portals in Vue 2) allows you to control where your components render, useful for modals, popups, and other elements that need to break out of their parent component.
10. Vue 3.0 uses Proxies for its reactivity system: Vue 3 now uses JavaScript's Proxy object for its reactivity system. This results in significant performance improvements and simplifies the reactivity system��s internal implementation.
11. Smaller Bundle Sizes: Vue 3 has a "tree-shaking" feature that ensures if a feature isn��t used, it won't be included in the final bundle. This leads to smaller bundle sizes.
In addition to these, there are several other improvements, refactorings, and features that come with Vue 3. If you're new to Vue or migrating from Vue 2.x, the Vue 3 documentation is an excellent resource to explore these features in detail.
