Top 12 React.js Libraries you should know about in 2019

React JS is a flexible and declarative JavaScript framework for building great user interfaces. It was built by the team at Facebook and it is currently being used by over 2 million projects on GitHub. It is relatively easy to create interactive user interfaces and build components-centric apps with this framework. It is also regularly maintained and has the fastest growing JavaScript community.

In this post you will be shown some React component libraries you should be familiar with in your workflow this year with focus on the regularly maintained ones, as there are more than 12 libraries out there.

1. Material UI

Material UI is one of the most popular React component libraries with over 48,000 stars on GitHub. The components and all the template elements are built according to the Google’s Material Design guidelines but are all React components. It ships with a lot of React templates and themes to help for customisation. It also provides a lot of UI elements out-of-the-box from cards to buttons to dialog boxes to icons and a lot of menus. It is also regularly updated as the last commit was a few days ago.

2. KendoReact

This is an interesting one, one of the many progress products that is really amazing. KendoReact is built specifically for development in React and has a 100 percent native mobile support out-of-the-box. Kendo ships with a set of components built by React developers with a world of experience for dialog boxes, guages, layouts, charts even animations. The components are also independent as they require no other dependency but React itself, it also has an import feature in the case that you already use an existing component library.

3. Blueprint

Blueprint is a React-based UI toolkit for the web built by the team at Palantir. It has currently been starred over 14,000 times on GitHub. It is arguably the best React UI library for data-driven projects like building a fintech user interface or interface for cryptocurrency or financial trade. It has a very extensive documentation for frontend development and it has great looking elements with nice finishes.

4. React Virtualized

If you are building React interactive interfaces for tables, grids and large lists, React Virtualized is the arguably the best UI component to use in your workflow. With over 16,000 stars on GitHub and regular updates with the last commit being last month. There are data-specific components you might not find anywhere else in the component list of React Virtualized like direction sorters and auto-sizers and masonry. Table configurations are also possible here. React Virtualized also comes with mobile support for Andriod and IOS out-of-the-box.

5. Evergreen

With over 8,000 stars on GitHubEvergreen is one amazing React UI framework for building ambitious products on the web created by Segment.

They are built to be very flexible as they follow React component guidelines, they are used as a design language for enterprise projects. The documentation is very easy to read, understand and implement and it is inspired by React Primitive UI. It was last updated few days ago showing it is regularly maintained.

6. React Bootstrap

Used by over 129,000 projects on GitHub, React Bootstrap is one of the most used React UI toolkit. As Bootstrap is also one of the biggest names in the CSS framework world, React Bootstrap brings you Bootstrap as you already know it into React components so you get too of your favorite frameworks in one, as every JavaScript inside Bootstrap core is replaced with React logic. Each component is interactive and accessible and ships with a lot of starter themes you can choose from to fast track your development process. It is also very regularly maintained as the last commit in the project is a few hours ago.

7. React Toolbox

React Toolbox is a set of React components that implements Google Material Design specification built on top of features like CSS modules, Webpack and ES6. It has a seamless Webpack integration and you can easily customize it. So much thought went into the documentation and it was also built using React Toolbox, there is a playground to test the various components in real-time. You can import components either individually or in bundles. It is being used by over 6,000 projects on GitHub and was last updated some months ago.

8. Belle

Belle is a configurable React component toolkit that provides you with a set of React components like Toggle, ComboBox, Rating, TextInput, Button, Card, Select and soon many more. Every one of these components are optimized for mobile and you are allowed to customize the styles yourself. These freedom can be in the individual component stylesheet or the global stylesheet. It is also optimized for accessibility with ARIA support. It has been starred over 2,000 times on GitHub and is regularly maintained too.

9. Reactstrap

Not to be confused with React Bootstrap, Reactstrap is a simple Bootstrap 4 and React component toolkit. It comes with create react app support which is a very big deal as a whole lot of React developers start their projects in the CLI with CRA. You can easily download it with your favorite package manager NPM or Yarn. It contains React Bootstrap 4 components that favor composition and control and does not depend on jQuery or Bootstrap javascript. However, popper is required for things like popovers, and auto-flipping drop-downs. It is currently being used by over 66,000 projects on GitHub and is regularly maintained, the last commit being some days ago.

10. Rebass

Rebass is a React primitive UI component built with modern styling conventions in mind like styled-components and emotion. It has 8 main components and those 8 have sub components, all being really small in size. It has very responsive and at the same time very easily-themeable style properties. It has a flexbox grid with box and flex components, it has been starred over 5,900 times on GitHub and is very regularly maintained.

11. React-md

React-md is a React component library that helps you creates a fully accessible material design styled website using React Components and Sass. With the separation of styles in Sass instead of inline styles, it is easier to create custom components with the existing styles. It allows for customizing your styles and it ships with this easy-to-read documentation which was also built with React-md. It is starred over 2,000 times on GitHub and the last commit to the project was few weeks ago showing that is regularly maintained.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

NBB: Ad-hoc CLJS Scripting on Node.js

Nbb

Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.

Status

Experimental. Please report issues here.

Goals and features

Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.

Additional goals and features are:

  • Fast startup without relying on a custom version of Node.js.
  • Small artifact (current size is around 1.2MB).
  • First class macros.
  • Support building small TUI apps using Reagent.
  • Complement babashka with libraries from the Node.js ecosystem.

Requirements

Nbb requires Node.js v12 or newer.

How does this tool work?

CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).

Usage

Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'
6

And then install some other NPM libraries to use in the script. E.g.:

$ npm install csv-parse shelljs zx

Create a script which uses the NPM libraries:

(ns script
  (:require ["csv-parse/lib/sync$default" :as csv-parse]
            ["fs" :as fs]
            ["path" :as path]
            ["shelljs$default" :as sh]
            ["term-size$default" :as term-size]
            ["zx$default" :as zx]
            ["zx$fs" :as zxfs]
            [nbb.core :refer [*file*]]))

(prn (path/resolve "."))

(prn (term-size))

(println (count (str (fs/readFileSync *file*))))

(prn (sh/ls "."))

(prn (csv-parse "foo,bar"))

(prn (zxfs/existsSync *file*))

(zx/$ #js ["ls"])

Call the script:

$ nbb script.cljs
"/private/tmp/test-script"
#js {:columns 216, :rows 47}
510
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
true
$ ls
node_modules
package-lock.json
package.json
script.cljs

Macros

Nbb has first class support for macros: you can define them right inside your .cljs file, like you are used to from JVM Clojure. Consider the plet macro to make working with promises more palatable:

(defmacro plet
  [bindings & body]
  (let [binding-pairs (reverse (partition 2 bindings))
        body (cons 'do body)]
    (reduce (fn [body [sym expr]]
              (let [expr (list '.resolve 'js/Promise expr)]
                (list '.then expr (list 'clojure.core/fn (vector sym)
                                        body))))
            body
            binding-pairs)))

Using this macro we can look async code more like sync code. Consider this puppeteer example:

(-> (.launch puppeteer)
      (.then (fn [browser]
               (-> (.newPage browser)
                   (.then (fn [page]
                            (-> (.goto page "https://clojure.org")
                                (.then #(.screenshot page #js{:path "screenshot.png"}))
                                (.catch #(js/console.log %))
                                (.then #(.close browser)))))))))

Using plet this becomes:

(plet [browser (.launch puppeteer)
       page (.newPage browser)
       _ (.goto page "https://clojure.org")
       _ (-> (.screenshot page #js{:path "screenshot.png"})
             (.catch #(js/console.log %)))]
      (.close browser))

See the puppeteer example for the full code.

Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above plet macro is similar to promesa.core/let.

Startup time

$ time nbb -e '(+ 1 2 3)'
6
nbb -e '(+ 1 2 3)'   0.17s  user 0.02s system 109% cpu 0.168 total

The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via npx this adds another 300ms or so, so for faster startup, either use a globally installed nbb or use $(npm bin)/nbb script.cljs to bypass npx.

Dependencies

NPM dependencies

Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.

Classpath

To load .cljs files from local paths or dependencies, you can use the --classpath argument. The current dir is added to the classpath automatically. So if there is a file foo/bar.cljs relative to your current dir, then you can load it via (:require [foo.bar :as fb]). Note that nbb uses the same naming conventions for namespaces and directories as other Clojure tools: foo-bar in the namespace name becomes foo_bar in the directory name.

To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:

$ classpath="$(clojure -A:nbb -Spath -Sdeps '{:aliases {:nbb {:replace-deps {com.github.seancorfield/honeysql {:git/tag "v2.0.0-rc5" :git/sha "01c3a55"}}}}}')"

and then feed it to the --classpath argument:

$ nbb --classpath "$classpath" -e "(require '[honey.sql :as sql]) (sql/format {:select :foo :from :bar :where [:= :baz 2]})"
["SELECT foo FROM bar WHERE baz = ?" 2]

Currently nbb only reads from directories, not jar files, so you are encouraged to use git libs. Support for .jar files will be added later.

Current file

The name of the file that is currently being executed is available via nbb.core/*file* or on the metadata of vars:

(ns foo
  (:require [nbb.core :refer [*file*]]))

(prn *file*) ;; "/private/tmp/foo.cljs"

(defn f [])
(prn (:file (meta #'f))) ;; "/private/tmp/foo.cljs"

Reagent

Nbb includes reagent.core which will be lazily loaded when required. You can use this together with ink to create a TUI application:

$ npm install ink

ink-demo.cljs:

(ns ink-demo
  (:require ["ink" :refer [render Text]]
            [reagent.core :as r]))

(defonce state (r/atom 0))

(doseq [n (range 1 11)]
  (js/setTimeout #(swap! state inc) (* n 500)))

(defn hello []
  [:> Text {:color "green"} "Hello, world! " @state])

(render (r/as-element [hello]))

Promesa

Working with callbacks and promises can become tedious. Since nbb v0.0.36 the promesa.core namespace is included with the let and do! macros. An example:

(ns prom
  (:require [promesa.core :as p]))

(defn sleep [ms]
  (js/Promise.
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
  []
  (p/do!
   (println "Doing stuff which takes a while")
   (sleep 1000)
   1))

(p/let [a (do-stuff)
        b (inc a)
        c (do-stuff)
        d (+ b c)]
  (prn d))
$ nbb prom.cljs
Doing stuff which takes a while
Doing stuff which takes a while
3

Also see API docs.

Js-interop

Since nbb v0.0.75 applied-science/js-interop is available:

(ns example
  (:require [applied-science.js-interop :as j]))

(def o (j/lit {:a 1 :b 2 :c {:d 1}}))

(prn (j/select-keys o [:a :b])) ;; #js {:a 1, :b 2}
(prn (j/get-in o [:c :d])) ;; 1

Most of this library is supported in nbb, except the following:

  • destructuring using :syms
  • property access using .-x notation. In nbb, you must use keywords.

See the example of what is currently supported.

Examples

See the examples directory for small examples.

Also check out these projects built with nbb:

API

See API documentation.

Top Reasons To Choose ReactJS

The principal concept at the back of ReactJS improvement become to discover a framework that allows in constructing a dynamic library with excessive performance. An appropriate instance of this becomes to offer newsfeeds on equal time whilst human beings are chatting. Optimization of the improvement technique and bringing on JavaScript become all that become required at that time. ReactJS is greater like an open-supply JavaScript library in place of a framework. Used for constructing superb consumer interfaces, it is ideal for rendering performance.

Reasons to pick out React.js/React/ReactJS

Out of the several reasons React.JS can be future of hybrid mobile app, some of the interesting ones are:

  • React’s virtual DOM is faster as it only refreshes a part of the page, rather than the conventional full refresh model
  • Easy to create UI Test Cases
  • Easy to reuse the code components
  • It can display components in large amounts quickly and efficiently
  • Specialized chrome extension makes it easy to debug
  • Any data changes require manual processing
  • It is view oriented
  • It’s one of the top JavaScript frameworks among ReactJS developers and is growing
  • Rendering the code from the server to browser will eventually improve the SEO of the webpage
  • It improves debugging speed, making it easier for developers
  • It covers both iOS and Android
  • As it makes use of reusable components, it becomes easy for the hybrid applications to render natively
  • React Native UI components can be applied without re-writing to an existing app’s code
  • It provides support for both front-end and server-side

Cons of ReactJS Making use of JSX which permits blending HTML with JavaScript is taken into consideration a critical drawback through ReactJS builders as it’s far complicated and has a steep mastering curve. Join ReactJS Online Training and learn the regular launch of the latest tools, documentation nonetheless stays incomplete, which makes it tough for brand spanking new ReactJS builders to apprehend and code. With the excessive tempo of improvement, ReactJS builders have to quickly research new methods of improvement. With rapid evolution, now no longer each developer is capable of preserve tempo. What’s our tackle it?

AngularJS is a featured framework at the same time as ReactJS is a library. You will need to write much less code with ReactJS and it even plays higher because of the implementation of digital DOM. As React has simply commenced its network is developing. Node.js is a JavaScript runtime that is rapid and lightweight. It may be used to create rapid and scalable networking packages. With Client-Side statistics rendering and a top configuration, ReactJS is an outright desire of JavaScript framework Developers.
