Originally developed in 2009, source maps have become ubiquitous, consumed by all major browsers and generated by every bundler in the JavaScript ecosystem. While the support for them is widespread, the specification itself has remained largely unchanged since 2009. Because of this, feature development has been very difficult to navigate. Some browsers have added their own functionality, but without the ability to influence the tools generating source maps, support is limited.
In 2023, we formed a group specifically dedicated to the completion and modernization of source maps. We presented to TC39 in July and became an official TC39 Task Group. Since then, we’ve been hard at work rounding out the current specification, looking forward to new features and making sure everyone agrees on the existing features. This talk will be focused on the new and exciting features we’re bringing to the specification. We’re actively working on Debug IDs for easier identification in error monitoring tools, Scopes for improved and consistent variable name and scope information in debugging tools and Range Mappings for helping debuggers find more accurate places in source code.

Nova JavaScript Engine - Exploring a Data-Oriented Engine Design
by Aapo Alasuutari
Date: 2024/06/03 - 13:00 CEST (UTC+2)
+In this talk we explore the benefits and drawbacks of writing a basic JavaScript engine in Rust using a data-oriented approach. This draws a stark contrast with the naturally object-oriented design of the ECMAScript specification and how most mainstream engines are built.

Sustainable Futures: Funding the Web Ecosystem
by Stephanie Stimac
Date: 2024/06/03 - 15:30 CEST (UTC+2)
+The web is a vital source of the world’s infrastructure and has shaped the way we work and live in the modern world. Surely such an integral piece of our day-to-day life is being built and maintained in a way that ensures it will last?
Unfortunately this isn’t the case. The current system funding access to the web is fragile, fractured and unsustainable. In this talk, I’ll give an overview of the current state of things, how we currently fund the web, why this is a problem, and possible ways to fix this so that access to information remains stable and sustainable for future generations to come.

Blitz: a truly modular, hackable web renderer
by Nico Burns
Date: 2024/06/03 - 16:30 CEST (UTC+2)
+Blitz is new web rendering engine that doubles down on Servo’s promise of modularity and hackability by combining a mix of Servo, Rust UI ecosystem, and bespoke components. It also (currently) eschews JavaScript scripting in favour of a Rust scripting API that can be driven directly by Dioxus or other Rust state management / reactivity frameworks.
This talk covers how Blitz’s approach differs to a traditional web engine, use cases, challenges, progress, and future plans.
