Redux vs Vue.js

Redux's concepts are heavily influenced by functional programming languages. It is built on data immutability, and makes use of several functional programming features such as currying (usually seen in Redux middlewares).

Redux supports server-rendering.

At only 2kB it's an extremely lightweight library.

Reducers are pure functions that returns the next state based on the previous state and an action (describing what should be changed). Since they are pure functions, they return a new state object instead of modifying the existing state. This ensures that it doesn't affect anything outside of the function's scope, making it free from unintended side effects and also makes debugging easier.

Since it's such a popular library, there's plenty of tutorials, guides, or other third-party resources online.

In Redux, the state of your application is held in a single object. The only way to change the state is to emit an action describing the change — there is no way to mutate state from the view, callbacks, or anywhere else. This makes the state of your application predictable and objective, and reduces the chances of any unintended state mutation by a callback somewhere else in your code.

Redux is most commonly used with React, but it can also be used with other UI libraries — Redux is strictly for state management only, thus it is agnostic to your 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.

Very useful.

Vue.js weighs in at 16kb min+gzip.

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.

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.

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.

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.

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.
