Web developers face two significant challenges when developing their applications and websites: latency and payload size. Given that web services rely on servers, the related communication incurs a cost in terms of latency. In contrast, the payload passed to the client incurs a communication cost, not to mention the computational cost to the client...

During its thirty years of existence, the World Wide Web has helped to transform the world and create digital economies. Although it started as a global information exchange, it has become the most significant available application platform on top of its initial target. One of the side effects of this evolution was perhaps suboptimal ways to delive...

In this lecture I consider the past, present, and the future of web development. The lecture is primarily aimed at beginning web developers to give them context to understand the forces behind the current situation.

Hydration is a common technique employed by current JavaScript-based frontend frameworks, such as React. In hydration, the application code is re-executed on the client to recover component boundaries, application state, and event listeners. In this article, we look into a new primitive called resumability that avoids thework as the necessary infor...

EURAS 2023 took place 28-30.06.2023 in Aachen, Germany. The 27th edition of the conference was heavily focused on standardisation while it also included another event called SIIT (Standardisation and Innovation in Information Technology) within its program. For 2023, the conference's main theme was "(Responsible) Standardisation for Smart Systems"....

Disappearing frameworks represent a new type of thinking for web development. In the current mainstream JavaScript frameworks, the focus has been on developer experience at the cost of user experience. Disappearing frameworks shift the focus by aiming to deliver as little, even zero, JavaScript to the client. In this paper, we look at the options a...

The evolution of the web can be characterized as an emergence of frameworks paving the way from static websites to dynamic web applications. As the scope of web applications has grown, new technical challenges have emerged, leading to the need for new solutions. The latest of these developments is the rise of so-called disappearing web frameworks t...

The web is the most prominent application platform globally, thanks to its vast user base. It started as a site platform in the 90s and morphed into an application one over time as interactive web applications became a reality. So-called single-page applications (SPAs) represent the current mainstream way of developing web applications but they com...

A significant portion of the web is powered by ECMAScript. As a web technology, it is ubiquitous and available on most platforms natively or through a web browser. ECMAScript is the dominant language of the web, but at the same time, it was not designed as such. The story of ECMAScript is a story of the impact of standardization on the popularity o...

Static site generation (SSG) is a common technique in the web development space to create performant websites that are easy to host. Numerous SSG tools exist, and the approach has been complemented by newer approaches, such as Jamstack, that extend its usability. Edge computing represents a new option to extend the usefulness of SSG further by allo...

In this poster titled "The future is mostly static" we recap the main findings of our ICWE 2022 paper.

Historically web sites have been developed using HTML for their markup either by authoring it directly or through abstraction to generate it. The currently available tools exist in a continuum of static, developer-oriented tools and dynamic services that cater to non-technical users. In this paper, we propose an approach that sits in the middle by...

Across time people have aected their surroundings. Relics of the past can be seen in the current world and landscape. Understanding history helps us to understand the present better and preserve our cultural heritage. This project aims to produce a window to the past by using computer generated graphics. Multiple views shall be created each going f...
