What is HTML5?

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.
HTML5 is a tool in the Languages category of a tech stack.

Decisions about HTML5

Here are some stack decisions, common use cases and reviews by companies and developers who chose HTML5 in their tech stack.

We exclusively use HTML5 instead of XHTML (or even older) HTML-versions. We like the new unity that HTML5 offers and try to keep our code according to the conventions. HTML5 and CSS 3 are natural partners and so it may not be surprising, that we're also using CSS 3. In most projects though, we extend the (already ubiquitous) standard features of CSS 3 through the use of SCSS, which enables us to get better insights into the aggregated, effective rules that apply for specific elements.

Hey I'm currently an undergraduate in computer science for almost 5 years now, still left with a few courses before I complete. I know that I'm not good at programming but still I choose developer based programming career approach, I have made plans to start my career in websites, etc, for that, I have purchased books related to HTML5, CSS , JavaScript. I'm currently learning HTML5 and CSS only and after this some JavaScript I am really confident in my decision but would love to know what an expert developer advice thanks in advance.

Our whole Vue.js frontend stack (incl. SSR) consists of the following tools:

  • Nuxt.js consisting of Vue CLI, Vue Router, vuex, Webpack and Sass (Bundler for HTML5, CSS 3), Babel (Transpiler for JavaScript),
  • Vue Styleguidist as our style guide and pool of developed Vue.js components
  • Vuetify as Material Component Framework (for fast app development)
  • TypeScript as programming language
  • Apollo / GraphQL (incl. GraphiQL) for data access layer (
  • ESLint, TSLint and Prettier for coding style and code analyzes
  • Jest as testing framework
  • Google Fonts and Font Awesome for typography and icon toolkit
  • NativeScript-Vue for mobile development

The main reason we have chosen Vue.js over React and AngularJS is related to the following artifacts:

  • Empowered HTML. Vue.js has many similar approaches with Angular. This helps to optimize HTML blocks handling with the use of different components.
  • Detailed documentation. Vue.js has very good documentation which can fasten learning curve for developers.
  • Adaptability. It provides a rapid switching period from other frameworks. It has similarities with Angular and React in terms of design and architecture.
  • Awesome integration. Vue.js can be used for both building single-page applications and more difficult web interfaces of apps. Smaller interactive parts can be easily integrated into the existing infrastructure with no negative effect on the entire system.
  • Large scaling. Vue.js can help to develop pretty large reusable templates.
  • Tiny size. Vue.js weights around 20KB keeping its speed and flexibility. It allows reaching much better performance in comparison to other frameworks.

Server side

We decided to use Python for our backend because it is one of the industry standard languages for data analysis and machine learning. It also has a lot of support due to its large user base.

  • Web Server: We chose Flask because we want to keep our machine learning / data analysis and the web server in the same language. Flask is easy to use and we all have experience with it. Postman will be used for creating and testing APIs due to its convenience.

  • Machine Learning: We decided to go with PyTorch for machine learning since it is one of the most popular libraries. It is also known to have an easier learning curve than other popular libraries such as Tensorflow. This is important because our team lacks ML experience and learning the tool as fast as possible would increase productivity.

  • Data Analysis: Some common Python libraries will be used to analyze our data. These include NumPy, Pandas , and matplotlib. These tools combined will help us learn the properties and characteristics of our data. Jupyter notebook will be used to help organize the data analysis process, and improve the code readability.

Client side

  • UI: We decided to use React for the UI because it helps organize the data and variables of the application into components, making it very convenient to maintain our dashboard. Since React is one of the most popular front end frameworks right now, there will be a lot of support for it as well as a lot of potential new hires that are familiar with the framework. CSS 3 and HTML5 will be used for the basic styling and structure of the web app, as they are the most widely used front end languages.

  • State Management: We decided to use Redux to manage the state of the application since it works naturally to React. Our team also already has experience working with Redux which gave it a slight edge over the other state management libraries.

  • Data Visualization: We decided to use the React-based library Victory to visualize the data. They have very user friendly documentation on their official website which we find easy to learn from.


  • Caching: We decided between Redis and memcached because they are two of the most popular open-source cache engines. We ultimately decided to use Redis to improve our web app performance mainly due to the extra functionalities it provides such as fine-tuning cache contents and durability.


  • Database: We decided to use a NoSQL database over a relational database because of its flexibility from not having a predefined schema. The user behavior analytics has to be flexible since the data we plan to store may change frequently. We decided on MongoDB because it is lightweight and we can easily host the database with MongoDB Atlas . Everyone on our team also has experience working with MongoDB.


  • Deployment: We decided to use Heroku over AWS, Azure, Google Cloud because it is free. Although there are advantages to the other cloud services, Heroku makes the most sense to our team because our primary goal is to build an MVP.

Other Tools

  • Communication Slack will be used as the primary source of communication. It provides all the features needed for basic discussions. In terms of more interactive meetings, Zoom will be used for its video calls and screen sharing capabilities.

  • Source Control The project will be stored on GitHub and all code changes will be done though pull requests. This will help us keep the codebase clean and make it easy to revert changes when we need to.

We are planning to develop a brand new UX for an already existing desktop software. The previous version is developed on C#.NET with Winforms & WPF. Our plan is to use JavaScript/HTML5 based frontend technologies for the new software. For some components, we are highly dependent on .NET/ .NET Core because the JS-based versions are not mature enough.

What would you choose for a desktop-based Engineering Software that supports multi-OS and has rich UI capabilities considering the .NET dependencies?

Thanks in advance,

HTML5 Alternatives & Comparisons

What are some alternatives to HTML5?
Android SDK
Android provides a rich application framework that allows you to build innovative apps and games for mobile devices in a Java language environment.
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
The core software is built by hundreds of community volunteers, and when you’re ready for more there are thousands of plugins and themes available to transform your site into almost anything you can imagine. Over 60 million people have chosen WordPress to power the place on the web they call “home” — we’d love you to join the family.
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.
