The KISS principle (Keep It Simple, Stupid) dictates that systems and processes should be kept as simple as possible, and that unnecessary complexity should be avoided. Therefore, for a web QUIZ Dynamic APP that has a MariaDB database, the simplest architecture would be a client-server architecture with a single server instance running the application stack, and a single MariaDB database instance running on a separate server.
To keep the architecture simple, it is recommended to avoid unnecessary complexity like microservices, load-balancing, and complex server architectures. The application can be hosted on a single server with enough resources to handle the expected traffic. The server infrastructure can be hosted on a cloud-based platform like AWS, Azure or GCP, allowing for easy scalability if necessary.
Overall, the most simple architecture for a web QUIZ Dynamic APP with a MariaDB database would be a single server architecture, with a front-end built using a modern framework, and a back-end built using a server-side language that interacts with a single MariaDB database instance. This approach keeps the application easy to maintain, scale and update.
Architecture
Using Svelte, Node.js, and MariaDB to build a Quiz app has several advantages, including fast performance, high security, ease of use, scalability, and a large community and ecosystem.
Fast performance: Svelte is designed to render components more efficiently, making the app faster and more responsive. Node.js is a lightweight and efficient runtime that can handle a high volume of requests. And MariaDB is designed to be fast and scalable, which makes it a great choice for handling large amounts of data.
High security: All three technologies have excellent security features. Svelte uses a compiler that generates very secure and optimized JavaScript code. Node.js has several built-in security mechanisms such as HTTPS, SSL/TLS encryption, and the Node Security Project that helps protect against common vulnerabilities. MariaDB has many advanced security features including encryption of data at rest and in transit, database authentication, and more.
Easy to use: Svelte has an easy-to-learn syntax that simplifies building reactive user interfaces. Node.js provides an event-driven architecture that makes it easy to handle I/O operations. MariaDB has a SQL-based syntax that is simple to learn and use, and many familiar tools and libraries can be integrated with it.
Scalable: All three technologies are designed to be scalable. Svelte makes it easy to create reusable components, which can be used to build complex applications. Node.js has a non-blocking I/O architecture, which allows it to handle multiple requests simultaneously. MariaDB is designed to handle high volumes of data and can be easily scaled horizontally and vertically.
Large community and ecosystem: Svelte, Node.js, and MariaDB all have large open-source communities that are constantly improving the technology, sharing knowledge and building useful tools and libraries.
Let's investigate what else we may use to see this application done.
What is NodeJS?
Node.js is an open-source, cross-platform, runtime environment used for developing server-side web applications. It is built on top of the V8 JavaScript engine used in Chrome browsers, and it allows developers to write server-side code using JavaScript. Node.js is known for its event-driven and non-blocking I/O model, which makes it very fast and efficient.
While Node.js provides developers with the core functionality needed to build web applications, additional frameworks and libraries are required to create a data-centric web application. These frameworks and libraries offer additional features and functionality to make building web applications easier and faster. Here are some key reasons why additional frameworks are needed:
Database integration: Node.js does not come with built-in database integration, so developers need to use a database framework like Sequelize or MongoDB Atlas to connect to databases and perform CRUD (Create, Read, Update, Delete) operations.
Web frameworks: Additional web frameworks like Express or Koa are needed to handle HTTP requests, response routing, and middleware implementation. These frameworks make it easier to create servers and APIs.
Templating engines: To render dynamic HTML pages, developers need to use templating engines like EJS or Handlebars. These tools allow developers to insert data into HTML code and change the HTML dynamically.
Authentication and Authorization: Developers need to implement authentication and authorization mechanisms to protect the application from unauthorized access. Libraries like Passport.js provide easy-to-use authentication tools.
Caching and optimization: Frameworks like Redis and Memcached help improve website performance by caching data and reducing the load on web servers.
In summary, Node.js is a powerful, efficient, and scalable tool for building web applications. However, additional frameworks and libraries are required to integrate databases, handle web requests, render dynamic pages, implement security measures, and optimize web performance.
What is Svelte?
Svelte is a modern, open-source JavaScript framework for building web applications. It is a component-based framework that allows developers to create reusable UI components and assemble them into larger applications. One of the key features of Svelte is that it compiles your code at build time instead of runtime, which makes the applications built with Svelte much faster and efficient.
Unlike some other popular JavaScript frameworks like React, Vue or Angular, Svelte doesn't rely on a virtual DOM to update the user interface. Instead, all changes are made directly to the actual DOM resulting in very high performance and fast updates.
Another great feature of Svelte is its simplicity. Svelte's syntax is straightforward and easy to learn for both beginners and experienced developers. The framework is also lightweight and does not require a lot of setup or additional configuration.
One of the most significant benefits of Svelte is its bundle size. Svelte produces small and optimized bundles, making it a great choice for building applications that need to be fast and performant. Thanks to its small size, Svelte can be used in environments with limited resources such as mobile devices or areas with low bandwidth.
Overall, Svelte is a great option for developers who want a fast, efficient, and easy-to-learn framework for building modern web applications with reusable UI components. If you're interested in trying out Svelte, there are plenty of resources available online to help you get started.
Frameworks
When it comes to choosing between AdonisJS, Koa + Plugins and Express.js + Plugins for creating a Svelte application with MariaDB database, it really depends on your project requirements, development style, and personal preferences.
Adonis
AdonisJS is a full-stack web framework that provides a lot of built-in functionality, including an ORM, CLI tool, and templating engine, which makes it easier to build web applications. If your project requires a lot of built-in features and you want a more opinionated architecture, AdonisJS might be the best choice.
Koa
Koa + Plugins is a minimalist web framework that focuses on the middleware approach and gives you more control over the application architecture. If you prefer a more flexible approach and want to install only the necessary plugins for your application, Koa + Plugins may be a good choice.
Express
Express.js is a popular web framework for building web applications with Node.js. It's flexible, lightweight, and provides a lot of community-driven plugins for various functionalities. If you prefer a more mature and flexible web framework, Express.js can be a good option.
What is MariaDB?
As for MariaDB database, all three frameworks have libraries and packages that are compatible with MariaDB, making them equally viable for this requirement.
MariaDB is an open-source relational database management system (RDBMS) that is a fork of MySQL. It was created and is maintained by the original developers of MySQL, after concerns over its acquisition by Oracle Corporation.
MariaDB offers many of the same features as its predecessor, including complex querying, full-text search, geospatial search, and replication. However, it also offers some features that are not present in MySQL, such as the ability to handle big data and additional storage engines. MariaDB also aims to be a drop-in replacement for MySQL and offers backward compatibility with MySQL APIs and commands.
The syntax and SQL commands of MariaDB are very similar to those of MySQL, which makes it easy for developers who are familiar with MySQL to switch to MariaDB. MariaDB also offers several new features, including improved enterprise-level security, increased performance, and more customization options.
One of the significant benefits of MariaDB is its popularity and strong community support. This means that there is a vast number of tutorials, guides, and resources available online to help users learn how to use the database system and troubleshoot issues.
Overall, MariaDB is a fantastic option for developers who are looking for a high-performance, open-source RDBMS that is easy to use and offers many of the features of MySQL while also providing some additional features and improved security.
Conclusion
