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.

Webpack vs. Snowpack: Getting Started with Snowpack

Here’s a brief comparison between webpack and Snowpack and a step-by-step guide to getting started with Snowpack.

webpack has been a developer favorite for years because of its effective module bundling capabilities. However, 2019 saw the introduction of Snowpack, a lighter alternative to webpack that promised increased speed and ease of use. This article will walk you through a brief comparison between these two tools and provide a step-by-step guide to getting started with Snowpack.

What is webpack?

Since its initial release in 2012, webpack has gained widespread recognition as an essential tool for web development. Webpack is a module bundler that takes a large number of JavaScript files and transforms them into a single output file or a few smaller files that you can use to run your app.

Webpack creates a dependency graph that manages the dependency relationships between your modules. With the addition of loaders, the tool can also bundle other file types besides JavaScript, such as CSS, PNG, JPG, and more. This effectively allows you to add all of your static assets — along with your JavaScript — to the dependency graph, which saves you the extra effort it takes to manage each dependency manually.

Other benefits of webpack include:

  • Streamlining and elimination of unused assets
  • Flexible control over asset processing
  • Code splitting into several JavaScript output files for faster page loads

But the powerful complexity of webpack also comes with some drawbacks:

  • Difficult configuration process
  • Steep learning curve
  • Slow build times

What is Snowpack?

Introduced in 2019, Snowpack is a new-generation, front-end build tool for JavaScript applications. Compared to webpack, Snowpack is faster, more lightweight, and much easier to configure for beginners.

How does Snowpack compare with webpack?

Unlike webpack, Snowpack doesn’t need to go through an entire rebuild and re-bundle process every time you modify and save an asset file. Webpack’s time-intensive build process accounts for the delay you experience between saving your files and seeing your changes load in the browser. A few developers have even reported wait times as long as 12 minutes for larger apps.

Some people have devised clever workarounds for boosting the speed of webpack, such as upgrading the UglifyJsPlugin, jettisoning image loaders, rethinking caching strategies, and switching from node-sass to sass-loader, to name a few.

For those who can’t afford to take days out of your project schedule to analyze build performance and cobble together an optimization plan, Snowpack is a better option.

How does Snowpack work?

So what’s different about Snowpack? It uses JavaScript’s ES module system (ESM) to write your file changes directly and instantly to the browser with no wait time. As opposed to bundlers like webpack, Snowpack builds every one of your files once and then caches them. It only needs to rebuild a file when you make changes, and the rebuild happens for that single file only.

Snowpack lets you work in a lightning-fast, unbundled development environment and even lets you keep your final builds unbundled and runnable. You also have the option to support bundled builds when it comes time to roll your app out to production. All you have to do is add the right plugin for your favorite bundler, or even write your own using the Snowpack plugin API.

In short, Snowpack offers the following advantages over a traditional bundler tool like webpack:

  • Changes written instantly to the browser with no wait time for rebuilds
  • Efficient cache for no duplicate downloads
  • Ability to import modules from CDN servers, thanks to Snowpack’s ESM foundation
  • Simple and easy configuration process
  • Easy learning curve

To learn more about how Snowpack stacks up against webpack, check out our blog post.

Get started with Snowpack

You’ve done the research, you’ve compared the tools, and you’ve decided that Snowpack is the one for you. So how do you get started? Luckily, you’ve come to the right place.

In the rest of this article, we’ll guide you through the steps to migrate your development environment and get your app up and running with Snowpack.

Prerequisites

Before you begin, check to ensure you have what you need to complete the setup. Thankfully, Snowpack’s requirements are minimal. To develop with the tool, you need:

  • A JavaScript app written with ESM-ready code
  • A modern browser that supports the ES module syntax, such as a recent release of Chrome, Firefox, or Edge

Tip: The modern browser requirement applies only to your development environment. Once you’ve created your final build with Snowpack and pushed it to production, users can view your site in any browser, modern or legacy.

1. Install Snowpack

You can use these installation commands:

With npm:

id="globalinstallation">global installation
npm install -g snowpack
local installation per project
npm install --save-dev snowpack

Snowpack’s creators recommend that you install locally rather than globally when possible.

With yarn:

local installation per project 
yarn add --dev snowpack

2. Start the Snowpack command-line interface (CLI)

There are three ways that you can run the Snowpack CLI locally:

  • Using the root package.json file
  • Using the npm command: npx snowpack
  • Using the yarn command: yarn snowpack

Webpack: A Bundler for Javascript and Friends

webpack

Webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

Install

Install with npm:

npm install --save-dev webpack

Install with yarn:

yarn add webpack --dev

Introduction

Webpack is a bundler for modules. The main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

TL;DR

  • Bundles ES Modules, CommonJS, and AMD modules (even combined).
  • Can create a single bundle or multiple chunks that are asynchronously loaded at runtime (to reduce initial loading time).
  • Dependencies are resolved during compilation, reducing the runtime size.
  • Loaders can preprocess files while compiling, e.g. TypeScript to JavaScript, Handlebars strings to compiled functions, images to Base64, etc.
  • Highly modular plugin system to do whatever else your application requires.

Get Started

Check out webpack's quick Get Started guide and the other guides.

Browser Compatibility

Webpack supports all browsers that are ES5-compliant (IE8 and below are not supported). Webpack also needs Promise for import() and require.ensure(). If you want to support older browsers, you will need to load a polyfill before using these expressions.

Concepts

Plugins

Webpack has a rich plugin interface. Most of the features within webpack itself use this plugin interface. This makes webpack very flexible.

NameStatusInstall SizeDescription
[mini-css-extract-plugin][mini-css]![mini-css-npm]![mini-css-size]Extracts CSS into separate files. It creates a CSS file per JS file which contains CSS.
[compression-webpack-plugin][compression]![compression-npm]![compression-size]Prepares compressed versions of assets to serve them with Content-Encoding
[html-webpack-plugin][html-plugin]![html-plugin-npm]![html-plugin-size]Simplifies creation of HTML files (index.html) to serve your bundles

Loaders

Webpack enables the use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.

Loaders are activated by using loadername! prefixes in require() statements, or are automatically applied via regex from your webpack configuration.

Files

![riot-npm]![riot-size]Riot official webpack loader

Performance

Webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.

Module Formats

Webpack supports ES2015+, CommonJS and AMD modules out of the box. It performs clever static analysis on the AST of your code. It even has an evaluation engine to evaluate simple expressions. This allows you to support most existing libraries out of the box.

Code Splitting

Webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.

Optimizations

Webpack can do many optimizations to reduce the output size of your JavaScript by deduplicating frequently used modules, minifying, and giving you full control of what is loaded initially and what is loaded at runtime through code splitting. It can also make your code chunks cache friendly by using hashes.

Contributing

We want contributing to webpack to be fun, enjoyable, and educational for anyone, and everyone. We have a vibrant ecosystem that spans beyond this single repo. We welcome you to check out any of the repositories in our organization or webpack-contrib organization which houses all of our loaders and plugins.

Contributions go far beyond pull requests and commits. Although we love giving you the opportunity to put your stamp on webpack, we also are thrilled to receive a variety of other contributions including:

  • Documentation updates, enhancements, designs, or bugfixes
  • Spelling or grammar fixes
  • README.md corrections or redesigns
  • Adding unit, or functional tests
  • Triaging GitHub issues -- especially determining whether an issue still persists or is reproducible.
  • Searching #webpack on twitter and helping someone else who needs help
  • Teaching others how to contribute to one of the many webpack's repos!
  • Blogging, speaking about, or creating tutorials about one of webpack's many features.
  • Helping others in our webpack gitter channel.

To get started have a look at our documentation on contributing.

If you are worried or don't know where to start, you can always reach out to Sean Larkin (@TheLarkInn) on Twitter or simply submit an issue and a maintainer can help give you guidance!

We have also started a series on our Medium Publication called The Contributor's Guide to webpack. We welcome you to read it and post any questions or responses if you still need help.

Looking to speak about webpack? We'd love to review your talk abstract/CFP! You can email it to webpack [at] opencollective [dot] com and we can give pointers or tips!!!

Creating your own plugins and loaders

If you create a loader or plugin, we would <3 for you to open source it, and put it on npm. We follow the x-loader, x-webpack-plugin naming convention.

Support

We consider webpack to be a low-level tool used not only individually but also layered beneath other awesome tools. Because of its flexibility, webpack isn't always the easiest entry-level solution, however we do believe it is the most powerful. That said, we're always looking for ways to improve and simplify the tool without compromising functionality. If you have any ideas on ways to accomplish this, we're all ears!

If you're just getting started, take a look at our new docs and concepts page. This has a high level overview that is great for beginners!!

Looking for webpack 1 docs? Please check out the old wiki, but note that this deprecated version is no longer supported.

If you want to discuss something or just need help, here is our Gitter room where there are always individuals looking to help out!

If you are still having difficulty, we would love for you to post a question to StackOverflow with the webpack tag. It is much easier to answer questions that include your webpack.config.js and relevant files! So if you can provide them, we'd be extremely grateful (and more likely to help you find the answer!)

If you are twitter savvy you can tweet #webpack with your question and someone should be able to reach out and help also.

If you have discovered a 🐜 or have a feature suggestion, feel free to create an issue on Github.
