I don’t just want to say “Whatever. Just pick and choose. Wish you all the best”. I’d like to provide you with a path for a more efficient learning process, so you can master more than one technology quickly. The bottom-left quadrant is where all Web Native solutions, as well as Xamarin, fit in. Your app is not compiled to native code and it wraps an interpreter to act as a bridge to everything in the platform.
Because individual views need to be dynamically rendered by a server or pre-rendered before access, potentially limiting hosting or adding data complexity. Because SPAs depend on JavaScript for rendering, the user experience depends much more significantly on the power of their specific device than it would in an MPA. The data required for a view to load relies on a specific client-side-only context, for instance, displaying controls for a piece of connected hardware.
It is also applicable to all cross-platform tiers I present later on. Vue is the only one of the three most popular web frameworks that is not backed by a big company. Due to its formidable simplicity and tiny footprint, it got attention from a massive and enthusiastic community. React was created by Facebook https://globalcloudteam.com/ to solve their own needs on the presentation layer. It introduced many aspects that suddenly became very popular, like virtual DOM, one-way data flow , and a mixture of HTML and JavaScript called JSX. Angular vs React vs VueAngular, originally called AngularJS, was presented to the world in 2010 by Google.
It’s not easy to spot the idiosyncrasies and points in common for a general classification. My intention was not to present the market share of each strategy or try to find the most productive, pleasant, or reliable way to build mobile apps. This is the closest tier to native development, but has the advantage of using one single codebase to target Android and iOS. Web solutions and, on different levels, all cross-platform solutions struggle to attain the excellence and comprehensiveness of Native Apps.
Microservice architecture implies that the backend of the app is split up into multiple single-purpose loosely coupled services. These services run separately, communicate via a network, and scale independently. In addition, microservices communicate synchronously or asynchronously .
Native Components
Multi-Page applications are very common on the web since all web applications used MPA architecture in the past. This architecture type reloads web pages for sending from/to the server through the user’s browser, and developers generally opt for MPA architecture if the application is pretty large. On the other hand, the client-side code communicates through HTTP requests exclusively and cannot read server files directly. Instead, it is parsed by the web browser and reacts to user inputs. In contrast to server-side code, client-side code can be viewed and modified by the user, and a combination of HTML, CSS, and JavaScript is utilized to build pages and content.
To be precise, however, React is considered just a library due to its flexible and less opinionated nature. Angular, on the other hand, is a strongly opinionated framework. The requester of a stream can start working on the response as soon as the first chunk of data is available, instead of waiting for the entire item to be complete. Finally, presuming the sidebar content contains secondary content such as tags and related items, it’s not critical enough to pull from the network. Depending on the frequency of updates, either network first or stale while revalidate is a good strategy here. Images should be cached with a cache first strategy, as has been previously discussed.
The persistence layer is a data server of the web application that collects, stores, and retrieves data (files, logic, website settings, confidential, and user-created information). As you’ve learned, the persistence tier sends data to the business layer upon request. The client-side and server-side of the web app interact using synchronous protocols, whereas server-side components of the app could also use asynchronous communication protocol.
- But I’m talking about making a Web App share code with a Mobile App.
- It’s definitely worth your time to do a little research in order to determine that you’re making the right decision for your needs.
- But generally speaking, Android apps lay on virtual machine instances to help deal with potential underlying specificities .

- As you’ve learned, the persistence tier sends data to the business layer upon request.
Every new feature, and every detail particular to Android or iOS makes that native feel harder and harder to access as you distance your app from the native tier. The previous page could be created using the app shell model in the SPA world, where the app shell is cached, then served, and content is loaded on the client side. Now, after going through all that, you may be thinking that you can only do this kind of per-section caching for single-page apps. The architecture of your software mirrors the applications you build. This interpretation of Conway’s law demonstrates the importance of web application architecture during development.
Mobile Apps Runtime Architecture
Angular is a spectacular web framework, and I really feel passionate about it. Even Vue, which is another amazing framework looks more similar to AngularJS from a bird’s-eye view. I believe this caused a significant movement away from Angular and contributed substantially to React’s popularity. Starting on the iOS side, just because it’s simpler, there’s only Apple ruling the world. Originally, developers needed to learn Objective-C, a proprietary object-oriented variation of C with some inspiration from SmallTalk (and an insanely long-named API).

The SPA is a widespread web application architecture framework, and there is a good reason for that. It offers an outstanding interactive user experience while keeping an app’s structure simple and lightweight. Single-page applications are built with JavaScript or TypeScript.
There is no need to establish multiple threads because Event Loop processes all requests one at a time, therefore a single thread is sufficient. These features enhance the scalability, performance, and throughput of Node.js web applications. And if it’s not something you want to get too involved with, hire a software development vendor who knows web application architecture inside-out. Containers make sense if you lack a clear plan on how to design web application architecture. You may also opt for containerization if you don’t want to tie yourself to a single environment. Your web app is fully rendered in advance and resides on the CDN.
This empowered developers to compile their code down to an intermediate bytecode that could be read and run by the JVM. In 2014, Apple announced Swift, a multi-paradigm language, which was a lot easier than its predecessor. It’s still possible to deal with Objective-C legacy code, but Swift has reached high maturity levels. So, if you’re planning to learn how to natively develop for iOS, Swift is definitely where you should start.
Native Apps Tier — Where you develop for each specific platform This is the tier where you must be aware of the idiosyncrasies of each platform. It’s not my intention to dig into them, I just want to mention a few things in a bit of context. Native, Web, PWA, hybrid, Cross-Compiled… what is “the best” way to develop for Android and iOS platforms? In this article, I’ll lay it all out so you can make an informed decision.

At the same time, web app architecture covers all elements of a web solution, including a server. There’s a convergence happening across mobile platforms and languages are getting more and more similar. I present many features from Kotlin, Swift, and TypeScript. In the end, I just want you to realize that they are not that different.
As long as the vendors or maintainers support their products, there’s a good reason to try each one mentioned in this study. You just need to define two sets of templates, one for web, another for mobile. In the seventh part of the series, I do a Hello World using Sidekick along with another project started from the CLI and a WhatsApp clone template I created for learning purposes. Nativescript has tools like Nativescript Sidekick and Nativescript Playground, as well as project structures based on templates that can be provided by the community.
The presentation level is the frontend of the web application located in your browser. This tier renders data from the backend into readable content and interface elements. The web server forwards the requests to the application web development architecture logic , which determines the course of action depending on the user’s access level and type of request. The JavaScript layer rests in the user’s browser and communicates with the backend to update the webpage in real-time.
What Is Web Application Architecture?
In the top-left, you find Native and Cross Compiled , where your app is compiled to native binaries. It talks directly to OEM Widgets (Original Equipment Manufacturer widgets — what we’ve been calling native components) as well as the native API. If you compare the most popular websites versus the most downloaded apps, it’s estimated that an average of 8.9 million unique web visitors per month access the top 1000 websites. That’s almost three times more than the average unique users of the top 1000 most downloaded apps. Writing programs that generate web pages using print statements was OK, but definitely not something that many programmers wanted to do full time. The rise in popularity of linux and other open source components such as the Apache web server, MySQL, and the PHP programming language brought about a real revolution in web development.
In the server-side rendered architecture, the web server generates the whole page on every request. This means the browser must reload after every time there’s a need to update the page. While it’s great when render times are low, the UX can go south if it takes too long.
3 Benefits Of Spas Over Traditional Web Applications
With Nativescript, you can develop using vanilla JavaScript, TypeScript, Angular and, more recently, Vue. Of course you can use other frameworks, but those are the ones officially supported. Another amazing framework that I’ve been particularly interested in over the last two years (I have a course on Udemy about it — in Portuguese), is Nativescript. It’s similar to React Native but is not tied to the React world (there’s an unofficial integration, Nativescript-Preact, though). In part 6 of the series, I do a quick Hello World in React Native. This shows, on Android Studio’s Layout Inspector, what components were rendered in the emulator.
Serverless Architecture
So, in other words, interface components are everything that creates the visuals of an application. Only now, after elaborating on a comparison between the two edges of my diagram, will I start talking about many of the cross-platform approaches to build mobile apps. All approaches have pros and cons, and might be either the best fit or the worst fit for your next project. In this guide, I’m classifying many different solutions into various tiers according to the distance their architectures are from the native platform.
Generally speaking, two codebases make things costly and hard to evolve. In theory, you don’t want to have an app with significantly more features on Android than iOS, or vice-versa. Your app is necessarily HTML/CSS/JavaScript executed by the native WebView . Cordova/PhoneGap or Capacitor can provide a bridge to allow your JavaScript code to talk to native APIs. On the other hand, this approach tends to have better UI performance, as all the components are the same as the ones used by Native Apps. Frameworks like Ionic wrap Cordova into their own solutions.
The event loop checks the nature of the request (blocking or non-blocking). Like the LAMP stack there are many tools that can fulfill the roles occupied by Mongo, Express Angular and Node.js. You can write an app just as MEAN using Flask, Postgresql and Vue.js. The odd syntax not withstanding you can see that the script is basically just a couple print statements that follow the HTTP protocol and spew out HTML. The output from the print statement is directed back across the network rather than to a terminal screen. On the other end of the wire the browser just knows it is getting HTML it has no idea that it came from a program rather than a file.
In the window management module, we’ve already seen how the in-app browser looks when a user navigates to a different origin from an installed PWA. Parsers optimized for streaming, including the browser, can progressively display the content of the stream before it’s complete, speeding up the perceived performance of the response. Even with these pros and cons, both architectures are valid for creating your PWA.
First things first, let me provide you with a bit of context. I am an IT senior consultant, and the idea of putting together this guide was born from discussions with one of our clients about what could be the best approach for them. And we realized that we did not have a well-defined strategy, a solid and reliable foundation, to help us come up with the right answer. Prev 020 Tools and debug Next 022 Complexity management Keeping a web app simple can be surprisingly complicated. In this module, you will learn how web APIs work with threading and how you can use this for common PWA patterns such as state management. Thanks to these three properties of streams, architectures built around streaming usually have a faster perceived performance than those that aren’t.
