Pros
Pro Can be used with any front-end stack
Vue can easily be integrated with other front-end libraries. This makes it an extremely versatile tool and it's easy to fix its shortcomings or missing features by just plugging in another library.
Pro Single file component
Very useful.
Pro Lightweight
Vue.js weighs in at 16kb min+gzip.
Pro Vuex store, events system
Pro Reactivity system
Pro CLI and Webpack integration
Pro Responsive server-side rendering
Since most of the mainstream server-side rendering implementations are synchronous, they can block the server's event loop when the application is complex.
Vue implements streaming server-side rendering, which allows you to render your component, get a readable stream and directly pipe that to the HTTP response. This allows you to have a responsive server and decreases the time your users have to wait before they get your rendered content.
Pro Supports inline templating
Although you can build components in JavaScript files, you can also use inline handlebars-like templating in your HTML views where simplicity is often a more sane choice.
Pro Can be made even lighter
Since the template-to-virtual-DOM and compiler can be separated, you can compile the templates in your machine and then deploying only the interpreter which is 12KB minified and gzipped.
Pro Support for both templates and JSX
You can choose to use either a templating language, or if you feel it's necessary to drop on a lower virtual-dom level, you can use JSX. This is simply done by replacing the template
option with a render
function.
Or alternatively, you can embed functions inside templates by using the <render>
tag.
Pro SEO friendly
Starting with Vue 2.0, Vue supports server-side rendering. This helps with SEO a lot, since the views are rendered directly on the server, which are indexed by search engines.
Pro VueRouter
Pro Functional
Functional approach.
Pro Server side rendering
Deku can render it's components and data server side, then it sends those components as HTML to the browser.
This ensures faster initial loading time and SEO friendliness out of the box, since it's indexed as any other static website by search engines.
Pro Easy to learn
Since Deku is very lightweight and has a rather small API, there's not much to learn. It's pretty easy to get started and build something with it.
Pro Can use JSX
Developers using Deku can choose to also use JSX if they want to. This is especially helpful for people who are moving from React to Deku.
Pro Good performance
Deku's diffing algorithm is considerably faster and performs better than most libraries. The dbmonster performance mini-app written in Deku renders roughly 16% faster than other libraries.
Cons
Con Poor typescript support
Very basic typescript support.
Con Very enterpris-ey in design and tooling
Con No support for legacy browsers
Deku does not support legacy browsers, or relatively old browsers for that matter. They only support the latest versions of the major web browsers.
Con Not a lot of learning resources
Since it's a rather new library and has a small community, there are not many examples where you can learn from out there. There are also few guides and the documentation is not amazing and has some parts that should be covered better.
