Why we should choose React Native over Flutter in 2024 [Complete Guide]
React Native and Flutter both are the most famous mobile app development frameworks among developers. And sometimes we get confused about which framework to develop our mobile app.
Both technologies are used to develop a cross-platform application.
What is a Hybrid application?
A simple definition of a hybrid application is an app that is a combination of a Native app and a Web app, Here your application can access all the hardware devices of your mobile and run similarly to a native app.
Some examples of Hybrid applications are Instagram, Twitter, Ubser, Gmail, and many more.
And yes React Native and Flutter both are used to develop a hybrid application
But the question is here who is the best for your project
So let's understand this and  measure both the technologies on the basis of some parameters like Design, Adoption, Documentation, Community, hardware access, and Performance and I will give some score on each of the parameters like Design
1) Design 
For any mobile application design is very important to the looks and feel the end user will get while using the app, This makes him use the app more and more.
In Flutter you can kickstart your project with code snippets and app templates offered by Flutter UI
But Flutter comes with a limited number of UI widgets so if you want to create any new design then you have to code it from scratch. So if you have any application design which is litter bit complex then the developer may take more time to design.
Whereas in react native you will get a waste number of UI libraries for your screen designing some of the most famous UI libraries of react native are React Native Paper, React native elements, and many more.
In react native complex to complex designs are easy to develop. And it also allows the developer to design the app with a native look and feel
Flutter : 0 and React Native: 1
2) Adoption : 
Flutter uses Dart programming language which was released in May 2017 whereas React native uses Javascript which is the most popular programming language nowadays
So if you need a website and a mobile application and if your web application is developed in React js, Angular Js, or Vue js then it becomes easy for the same developer to learn to react native and develop a mobile app for you,  that means you can develop and web and mobile app with the same developer which will, after all, reduce your cost, Whereas you have to hire a separate developer who know Flutter and Dart to develop the app, Which means the adoption curse for a web developer is high to switch to react native as compared to Flutter.
Score Board Flutter : 0 and React Native: 1
3) Documentation : 
Documentation of Flutter is excellent, highly organized, and yes has all the answers to the possible questions,
Although development in Flutter is a little bit slow then also developer consider it due to its well-structured documentation.
Scoreboard : Flutter: 1 and React Native : 0
4) Community 
React Native was released in 2015 by Facebook and it is a very popular framework on Stackoverflow with more than 300k tagged questions 
Whereas Flutter was released in 2017 by Google so it has a smaller community and developers are adopting it slowly, Flutter has around 89k+ tagged questions on StackOverflow.
Scoreboard: Flutter : 0 and React native: 1
5) Hardware access 
When we are going to develop a mobile application we need some hardware access to device like storage, camera, speaker, gyro, gesture, and many other things, 
It is difficult for web applications to access hardware devices
But
Here we are talking about a hybrid framework which is flutter and react native
Flutter has unified libraries to access your hardware devices whereas react native has a wide range of libraries from the community to access the hardware
From my point of view, both frameworks can easily access hardware and give you a better experience but yes in Flutter you will get a limited number of libraries, and react native offers a robust ecosystem of modules that enables you to access and utilize the hardware capabilities.
In this case, both are winners so
Scoreboard ▶️  Flutter: 1 React Native :1
6) Performance 
When we develop an app user first checks the performance if the app is running slow and hanging then he directly uninstalls the mobile app. 
So, in this case, you have to be very serious about choosing a technology according to your requirement. 
Flutter is very famous among developers due to its high-performing UI rendering and it uses its own rendering engine whereas react native relies on native UI Components and it suffers some performance issues due to bridge communication between javascript and native code
Scoreboard : Flutter: 1 and React native : 0
So hope you understand this
So let's count the final result 
The total score of React Native is 4 👏
The total score of Flutter is 3 
So our winner is React native  As you can see on the parameters like  Design, Adoption, Documentation, Community, hardware access, and Performance react native become the winner and these are very important parameters for anyone who is going to develop and mobile application on a large scale. 
Many people consider React native in this case also because it is very compatible with Node js which is being used now a day for developing scalable applications and Flutter is compatible with Firebase as a backend.
Google Trend
If we check on Google Trends which is more popular between React Native and Flutter so obviously we can see that Flutter is more popular than react native Let me give you the reason 
See Flutter is new and it is a product of Google you know that Google is the king of the internet so it definitely flutter will become popular and people want to learn this and after all the documentation of Flutter is very structured and easy to understand for a new developer 
Tumblr media
Blue is React and Red is Flutter
But let's come one step back
React Native is a mobile framework of React (Which is a very famous Js library) and is widely used in frontend development
First, let's see the statistic of React js with other frameworks 
Tumblr media
Here React is high in the trend
React is popular because of its performance and many companies like User, Meta, and Zendesk used it for their UI development 
Now why I am shown this 
Because you must know that if any React developer wants to learn app development also then he will not prefer Flutter he will prefer react native so if you want to develop any project in react js or you can say MERN stack then you must prefer React Native with it.
Hope you understand what I want to tell.
Why react native is considered to develop and highly scalable mobile app
There are many reasons to consider react native for developing highly scalable applications. Firstly, it allows developers to write code once and deploy it across multiple platforms, such as iOS and Android. This code reusability significantly reduces development time, effort, and money, making it efficient for scaling applications.
The next thing is, React Native offers excellent performance by reutilizing native components. It helps in the native rendering capabilities of each platform, resulting in a complex UI becoming faster and smoother. This performance optimization helps to maintain scalability even as the app grows in complexity.
Additionally, React Native has a vast ecosystem of ready-to-use libraries and components, which accelerates development and further enhances scalability. These libraries provide access to device features and APIs, allowing developers to integrate various functionalities with any problem.
Like Flutter, React Native also allows for hot reloading, enabling developers to see real-time changes during the development process.
So the final conclusion is, React Native is backed by a strong community and continuous updates from Facebook (now Meta), ensuring ongoing support and improvements. This support system adds to its credibility and makes it a reliable choice for building scalable mobile applications.

Layoutit Grid: Learning CSS Grid Visually With a Generator
Layoutit Grid is an interactive open source CSS Grid generator. It lets you draw your designs and see the code as you go. You can interact with the code, add or remove track lines and drag them around to change the sizing — and you get to see the CSS and HTML change in real time!
Tumblr media
Add some tracks and see how they’re made in CSS
When you are done with a layout, you can create a CodePen or grab the code to jumpstart your next project. The tool brings the code to the forefront, helping you learn CSS grid as you work directly with it.
CSS Grid is a whole new way of thinking about layouts
We can now create robust responsive layouts for our web experiences. We can finally learn to design with a coherent set of layout tools instead of memorizing piles of hacks to force elements into position.
Now, I’m not saying a generator like this excuses us from knowing the code we write. We should all learn how CSS Grid and Flexbox work. Even if your stronghold is JavaScript, having a solid foundation in CSS knowledge is a powerful ally when communicating your ideas. When sharing a prototype for a component, a UX interaction, or even an algorithm in an online sandbox, the way in which your work is presented can make a big difference. The ability to develop proper layouts — and define the styles that create them — is fundamental.
Crafting layouts in CSS should not be a daunting task. CSS Grid is actually quite fun to use! For example, using named grid areas feels like an ASCII art version of drawing a design on a piece of paper. Lets create the layout of a photos app, a feed of pics and the people in them side by side for its main content and the typical header, footer and a config sidebar.
.photos-app {   /* For our app layout, lets place things in a grid */   display: grid;   /* We want 3 columns and 3 rows, and these are the responsive      track sizes using `fr` (fraction of the remaining space) */   grid-template-columns: 20% 1fr 1fr;   grid-template-rows: 0.5fr 1.7fr 0.3fr;   /* Let's separate our tracks a bit */   gap: 1em;   /* We now have 3x3 cells, here is where each section is placed */   grid-template-areas:     "header header header"  /* a header stretching in the top row */     "config photos people"  /* a left sidebar, and our app content */     "footer footer footer"; /* and a footer along the bottom row  */ } .the-header {   /* In each section, let's define the name we use to refence the area */   grid-area: "header"; }
This is just a small subset of what you can build with CSS Grid. The spec is quite flexible. Areas can also be placed directly using line numbers or names, or they can be placed implicitly by the browser, with the content distributed inside the grid automatically. And the spec continues to grow with additions, like subgrid.
At the same time, working with grids can be difficult, just like anything that requires a new way of thinking. It takes a lot of time to wrap our heads around this sort of thing. And one way to help do that is to…
Learn while playing
When you are learning CSS Grid, it is easy to feel intimidated by its notation and semantics. Until you develop some muscle memory for it, kickstarting the learning process with visual and interactive tools can be an excellent way to overcome that early trepidation. A lot of us have used generators while learning how to create shadows, gradients, Markdown tables, and so on. Generators, if built with care, are great learning aids.
Let’s use Layoutit Grid to recreate the same design in our example.
Open Layoutit Grid
Generators like this aren’t meant to be leaned on forever; they’re a stepping stone. This particular one helps you experience the power of CSS Grid by materializing your designs in a few clicks along with the code to make it happen. This gives you the early wins that you need to push forward with the learning process. For some of us, generators permanently remain in our toolboxes. Not because we do not know how to craft the layouts by hand, but because having the visual feedback loop help us to quickly convert our ideas into code. So we keep playing with them.
Sarah Drasner has also created a CSS Grid generator that’s worth checking out as well.
Learn by building
Leniolabs recently open-sourced Layoutit Grid and added new features, like interactive code views, area edition, history and offline support. And there are several more in the making.
View on GitHub
If you have ideas to improve the tool, get in touch! Open an issue and let’s discuss it on GitHub. Going into meta territory, you can also learn about the CSS Grid spec by helping us build the tool. 
We use the app to keep track of best practices in creating performant interactive web experiences. It is now powered by the newly released Vue 3 using <script setup> components and built with Vite, a new dev tool that doesn’t bundle the app while developing, which gives us instant feedback during development. If you are curious and want to build with us, fork the repo and let’s learn together!

A Lovely Spring View: Spring Boot & Vue.js
It´s time to shed some light on the integration of Vue.js with the popular Java Enterprise framework Spring Boot! Both frameworks are shining stars in their respective domain – but how could they be set up together properly? What is a practical project structure and build process? How does the development work locally and how is the app deployed? Let´s elucidate these questions!
Vue.js looks like a great choice!
I have to admit: I am not a frontend developer! I really like to play around with “backend stuff” like Spring Boot, web and microservices, automating whole infrastructures with Vagrant, Packer, Ansible and Docker – while I just wanted to scale my apps with Spring Cloud, Docker Swarm and Traefik…
But wait! Isn´t there a frontend I need to build from time to time?! Yeah, there aren´t that many occasions, but sometimes I have to get my hands dirty with some JavaScript code.
Tumblr media
Especially when you are giving lectures at university and try to digitize some old paper processes with your students. And if you ask our CTO, this “backend developer” thing won´t be around much longer…
Tumblr media
Alright then, we need to choose the “right” frontend framework – having nearly no clue. The last web app I built was based on Angular 1 – and it felt like a good choice! I loved the coding experience and after a day of training, I felt able to write awesome frontends… But now it’s two years later and I heard rumors that there was a complete rewrite of Angular (2), a new kid in town from Facebook (React) and lots of ES201x stuff, dependency managers, linters and more. Whew! But if I get my colleagues right, Vue.js isn´t the worst choice! Just take a look at all those posts that have been written in our blog this spring (especially if you need a deeper dive into Vue.js):
Rapid prototyping with Vue.js Vue.js – it’s simple until you make it complicated Vue.js & React – JavaScript UI Frameworks im Vergleich
Also, other projects move from one of the other big frameworks like Angular to Vue.js. Some of the main points are Vue.js’ much flatter learning curve and the higher coding speed compared to Angular and React. And the introduction phrase sounds really great:
Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects.
Project setup
So I think it could be a good idea to invest some time into Vue.js. As you may know, I strive to write quite comprehensible blog posts – you can find every bit inside the example project on GitHub. So let´s have a quick look into the project´s structure. The project uses Maven´s Multi Module capabilities to achieve a clean setup:
Tumblr media
The pom.xml in the project´s root folder spring-boot-vuejs therefore contains the two modules backend and frontend:
frontendbackend
Spring Boot 2.0.x backend
The easiest way to create a new Spring Boot app is – as Josh Long really likes to emphasize – start dot spring dot io! Just initialize a Spring Boot app with the Web dependency and place the generated zip´s contents into the backend folder. There are only two things I had to change for the Vue.js integration. First the spring-boot-starter-parent has to move to our parent pom.xml in the root directory.
Second – and this is a key concept of our project setup here – we need to copy the generated HTML, JavaScript & CSS to a resources folder where it can be served by Spring Boot´s embedded Webserver later easily. This could be done with the maven-resources-plugin:
maven-resources-plugincopy Vue.js frontend contentgenerate-resourcescopy-resourcessrc/main/resources/publictrue${project.parent.basedir}/frontend/target/diststatic/index.html
It just takes the results from the frontend build process (placed in /frontend/target/dist) and places them into /backend/src/main/resources/public folder. With this a simple java -jar backend-0.0.1-SNAPSHOT.jar will run our Spring Boot App and serve all the frontend assets. But first of all let´s build a frontend to serve!
Just for later needs we also create a simple RESTful Service in BackendController.java and use the great testing tooling from rest-assured together with Spring Boot to test our services inside the BackendControllerTest.class:
@RunWith(SpringRunner.class) @SpringBootTest( classes = SpringBootVuejsApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT ) public class BackendControllerTest { @LocalServerPort private int port; @Test public void saysHello() { when() .get("http://localhost:" + port + "/api/hello") .then() .statusCode(HttpStatus.SC_OK) .assertThat() .body(is(equalTo(BackendController.HELLO_TEXT))); }
Vue.js 2.5.x frontend
If you want to reproduce every step mentioned here, you´ll need a working Node.js installation as a prerequisite. Just use your preferred package manager and install it – like brew install node on a Mac. We´ll also need the Vue.js command line interface vue-cli, which could be installed with the help of npm, the Node.js Package Manager:
npm install --global vue-cli
To initialize a project skeleton for Vue.js, we only have to execute the following inside the frontend directory:
vue init webpack frontend
This command results in some questions that require answers:
Tumblr media
The generated skeleton is a great starting point for your Vue.js experiments. If you want to learn more about installing Vue.js, just head over to the docs.
The frontend-maven-plugin
The easiest way to handle every bit of the quite complex frontend build process with npm, node.js, ESLint, Karma, webpack and so on is to just use the frontend-maven-plugin. If you know Maven, that’s everything you need! Just add the plugin to the frontend’s pom.xml and you can use your well-known Maven commands:
com.github.eirslettfrontend-maven-plugin${frontend-maven-plugin.version}install node and npminstall-node-and-npmv9.11.1npm installnpmgenerate-resourcesinstallnpm run buildnpmrun build
The configuration of the frontend-maven-plugin ensures that the correct Node.js and npm versions are installed – with Node.js version > 4.0.0 the plugin takes care of the corresponding npm version, so you don´t have to explicitly configure it here. Additionally it installs all of our frontend dependencies (via npm install) and runs the full frontend build process with npm run build.
Tell webpack to output build contents to /target
The standard Node.js way is to create a dist directory for builds which contain the minified source code of our web application. But as we use Maven here, we need to have everything in the target directory. Therefore we need to change the generated frontend/config/index.js and replace the following lines:
index: path.resolve(__dirname, '../dist/index.html'), assetsRoot: path.resolve(__dirname, '../dist'),
with
index: path.resolve(__dirname, '../target/dist/index.html'), assetsRoot: path.resolve(__dirname, '../target/dist'),
First app run
Now we already have everything in place to fire up our Spring Boot powered Vue.js application! Just enter the project’s repository and let Maven do its job inside the root spring-boot-vuejs directory:
mvn clean install
This will build our whole app and we can simply do a:
java -jar backend/target/backend-0.0.1-SNAPSHOT.jar
Now let´s open our browser and hit http://localhost:8088/. That´s it, our app should now look like this:
Tumblr media
Development process
Although we now have our app successfully running for the first time, we need to take a closer look at how the development process could work with Spring Boot and Vue.js integrated. Because we don´t really want to wait for the full Maven/npm build to complete and wait for our app to be fired up with java -jar until we see a simple frontend element changed in the browser!
We want to get much faster feedback if we change frontend code. Luckily the webpack-dev-server comes to the rescue! This piece of magic will just update and build every change through all the parts of our JavaScript build chain instantly – and is pre-configured in our setup out of the box. The only thing to start the webpack-dev-server is to switch over to the frontend directory and run:
npm run dev
That’s it! Just try it yourself. The command automatically opens your browser. Just enter the Vue.js source in frontend/src and change something. It will instantly be visible
Tumblr media
Another neat tool is the Vue.js browser extension. Just install it into your Chrome or Firefox and you should have a deep look into your Vue components inside the Browser´s development tools:
Tumblr media
Accessing Spring Boot REST services from Vue.js frontend
As we´re integrating Vue.js with Spring Boot, we for sure want to call some of those nice RESTful web services our Spring Boot backend provides us with. There are many libraries to access web services that one can use with Vue.js. One of them is axios, which is a quite popular Promise API based HTTP client with a huge number of GitHub stars. To use axios in our project, we only have to install the npm dependency:
npm install axios --save
Calling a REST service with Axios is simple. Go into the script area of your component (e.g. in the Service.vue) and add:
import axios from 'axios' data () { return { response: [], errors: [] } }, callRestService () { axios.get(`api/hello`) .then(response => { // JSON responses are automatically parsed. this.response = response.data }) .catch(e => { this.errors.push(e) }) } }
Now inside the template area of your Vue.js component you can request a service call with the callRestService() method – and access the response data accordingly:
CALL Spring Boot REST backend service
Get out of the same-origin policy (SOP) hell
The HTTP calls with axios are working fine – except when we try to use them in our local fast feedback development process with the webpack-dev-server. Why? Because if we start the webpack-dev-server via npm run dev, it will serve our web application on http://localhost:8080. But our Spring Boot REST backend runs on http://localhost:8088! As a core concept of web application security, the same-origin policy (SOP) will then prevent our Vue.js frontend from accessing its Spring Boot backend – resulting in SOP errors.
One way to solve this problem is to use the Cross Origin Resource Sharing Protocol (CORS). Although this isn´t a big deal with both axios and Spring Boot, there´s a much more nifty solution. Thanks to my colleague Daniel who pointed me to the nice proxying feature of webpack-dev-server, we don´t need to configure all the complex CORS stuff!
According to the Vue.js Webpack Template the only thing we need to configure is a Proxy for our webpack-dev-server requests. This can easily be done in the frontend/config/index.js – right inside the dev.proxyTable field:
dev: { ... proxyTable: { // proxy all webpack dev-server requests starting with /api to our Spring Boot backend (localhost:8088) '/api': { target: 'http://localhost:8088', changeOrigin: true } },
With this configuration in place, the webpack-dev-server uses the really handy http-proxy-middleware to proxy all frontend requests with a preceding /api from http://localhost:8080 to http://localhost:8088 – including changing the Origin HTTP header accordingly. Remember that our Spring Boot REST services are configured to serve those requests to /api on class level:
@RestController() @RequestMapping("/api") public class BackendController { @RequestMapping(path = "/hello") public @ResponseBody String sayHello() { return "Hello from Spring Boot Backend!"; }
The proxyTable configuration is finally used in the frontend/build/dev-server.js to configure the proxyMiddleware. We don´t need to change anything here, but I wanted to show the usage of the http-proxy-middleware:
// proxy api requests Object.keys(proxyTable).forEach(function (context) { var options = proxyTable[context] if (typeof options === 'string') { options = { target: options } } app.use(proxyMiddleware(options.filter || context, options)) })
Is the app ready for deployment?
OK, now I can´t really conceal that I love that Continuous Delivery stuff.
Tumblr media
So no example project is complete as long as it´s not running anywhere “productively”.
As you may already have found out, the example project has a live deployment configuration for Heroku: With every push into the master branch, our Spring Boot powered Vue.js app is built by TravisCI and deployed to:
https://spring-boot-vuejs.herokuapp.com
In the course of setting up the example project I really fell in love with the great Automatic deploys feature of Heroku and Heroku Pipelines. If the “Wait for CI to pass before deploy” checkbox is selected, we get a fully working pipeline and are able to demonstrate that our example project is also ready for deployment! Thanks again for pointing me to this great platform, Benedikt!
And that´s it!
Now we found a nice way to integrate Vue.js and Spring Boot. As both are really popular frameworks in their respective domain, I hope this introduction is helpful to some of you folks. If you manage to work through all the points shown in this post, you will have a solid project setup that can be used for both local development and deployment – mainly because both Vue.js and Spring Boot bring in such great features. And as “old school” Maven is supported by nearly every platform, this setup is ready for anything you can imagine. Let me know about your great Spring Boot powered Vue.js apps!

Layoutit Grid: Learning CSS Grid Visually With a Generator
Layoutit Grid is an interactive open source CSS Grid generator. It lets you draw your designs and see the code as you go. You can interact with the code, add or remove track lines and drag them around to change the sizing — and you get to see the CSS and HTML change in real time!
Tumblr media
Add some tracks and see how they’re made in CSS
When you are done with a layout, you can create a CodePen or grab the code to jumpstart your next project. The tool brings the code to the forefront, helping you learn CSS grid as you work directly with it.
CSS Grid is a whole new way of thinking about layouts
We can now create robust responsive layouts for our web experiences. We can finally learn to design with a coherent set of layout tools instead of memorizing piles of hacks to force elements into position.
Now, I’m not saying a generator like this excuses us from knowing the code we write. We should all learn how CSS Grid and Flexbox work. Even if your stronghold is JavaScript, having a solid foundation in CSS knowledge is a powerful ally when communicating your ideas. When sharing a prototype for a component, a UX interaction, or even an algorithm in an online sandbox, the way in which your work is presented can make a big difference. The ability to develop proper layouts — and define the styles that create them — is fundamental.
Crafting layouts in CSS should not be a daunting task. CSS Grid is actually quite fun to use! For example, using named grid areas feels like an ASCII art version of drawing a design on a piece of paper. Lets create the layout of a photos app, a feed of pics and the people in them side by side for its main content and the typical header, footer and a config sidebar.
.photos-app {   /* For our app layout, lets place things in a grid */   display: grid;   /* We want 3 columns and 3 rows, and these are the responsive      track sizes using `fr` (fraction of the remaining space) */   grid-template-columns: 20% 1fr 1fr;   grid-template-rows: 0.5fr 1.7fr 0.3fr;   /* Let's separate our tracks a bit */   gap: 1em;   /* We now have 3x3 cells, here is where each section is placed */   grid-template-areas:     "header header header"  /* a header stretching in the top row */     "config photos people"  /* a left sidebar, and our app content */     "footer footer footer"; /* and a footer along the bottom row  */ } .the-header {   /* In each section, let's define the name we use to refence the area */   grid-area: "header"; }
This is just a small subset of what you can build with CSS Grid. The spec is quite flexible. Areas can also be placed directly using line numbers or names, or they can be placed implicitly by the browser, with the content distributed inside the grid automatically. And the spec continues to grow with additions, like subgrid.
At the same time, working with grids can be difficult, just like anything that requires a new way of thinking. It takes a lot of time to wrap our heads around this sort of thing. And one way to help do that is to…
Learn while playing
When you are learning CSS Grid, it is easy to feel intimidated by its notation and semantics. Until you develop some muscle memory for it, kickstarting the learning process with visual and interactive tools can be an excellent way to overcome that early trepidation. A lot of us have used generators while learning how to create shadows, gradients, Markdown tables, and so on. Generators, if built with care, are great learning aids.
Let’s use Layoutit Grid to recreate the same design in our example.
Open Layoutit Grid
Generators like this aren’t meant to be leaned on forever; they’re a stepping stone. This particular one helps you experience the power of CSS Grid by materializing your designs in a few clicks along with the code to make it happen. This gives you the early wins that you need to push forward with the learning process. For some of us, generators permanently remain in our toolboxes. Not because we do not know how to craft the layouts by hand, but because having the visual feedback loop help us to quickly convert our ideas into code. So we keep playing with them.
Sarah Drasner has also created a CSS Grid generator that’s worth checking out as well.
Learn by building
Leniolabs recently open-sourced Layoutit Grid and added new features, like interactive code views, area edition, history and offline support. And there are several more in the making.
View on GitHub
If you have ideas to improve the tool, get in touch! Open an issue and let’s discuss it on GitHub. Going into meta territory, you can also learn about the CSS Grid spec by helping us build the tool. 
We use the app to keep track of best practices in creating performant interactive web experiences. It is now powered by the newly released Vue 3 using <script setup> components and built with Vite, a new dev tool that doesn’t bundle the app while developing, which gives us instant feedback during development. If you are curious and want to build with us, fork the repo and let’s learn together!
