Vue3 is a milestone in the world of modern web development bringing javascript developers an evolved set of tools to build more powerful and performant apps than ever before.
whether it’s a small side project or a large enterprise-level app Vue3 is both intuitive while enjoyable to use
let’s take a look at some of the most exciting new features you can take advantage of as a v3 developer
Vue 2 is quite small at around 20KB zipped at run time and Vue3 is just as compact while bringing you
new features and improvements Vue 3 also allows us to only import the parts of the library that we need as a result whatever
In Vue 3 the virtual dom has been rewritten from the ground up with a new diffing algorithm that uses compiler-based optimizations.
this results in faster rendering times one of the biggest features coming in Vue 3 is the new composition API with Vue 2.
sometimes our large components ended up with features dispersed amongst the components options
which could make them difficult to manage and maintain with the composition API.
Vue 3 Live Release
Vue 3 provides a new alternative syntax that gives developers a better way of managing features and functionality across their components.
allowing you to easily scale your applications source code is written entirely in typescript which means enhanced support for typescript users.
but using it is optional and not required most front end framers require us to wrap our component’s template code in a single element because sibling elements aren’t allowed.
but with view three we can now use multi-root components sometimes a piece of a component’s template belongs there logically.
it would be preferable to render it somewhere else Vue 3 gives us the new teleport component which allows us to specify template HTML.
that we can send to another part of the dom this is useful for things like modals which may need to be placed in different parts of the Vue app.
these are all just a handful of ways Vue 3 empowers you and your team to build a better Vue app.
so many new features to learn you’ll want to check out the official Vue 3 docs.
