How to Improve Your Web Application’s Security using Mozilla Observatory
We have used Mozila Observatory to improve our security rating from F to B+, (https://observatory.mozilla.org/analyze/live.copilot.fabric.inc). This talk will be about how one can leverage the tool to enhance the security posture of their web applications. In this talk, we will explore how to enhance web application security using the Mozilla Observatory. We will cover essential security measures such as Content Security Policy, Cookies, Cross-origin Resource Sharing, HTTP Public Key Pinning, HTTP Strict Transport Security, Redirection, Referrer Policy, Subresource Integrity, X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection, providing practical insights and guidance on their implementation.

Beyond the Basics: Securing JavaScript Applications
JavaScript powers dynamic and interactive applications that millions of users use everyday. In this talk, we will highlight the vulnerabilities and well-known risks when dealing with various types of JavaScript applications. We’ll also discuss relevant risks and issues concerning insecure third-party dependencies and vulnerabilities in Node.js modules as well. In addition to this, we’ll discuss several techniques and solutions when handling authentication, authorization, and session management for Single Page Applications (SPAs). We’ll discuss the best practices and strategies concerning Content Security Policies (CSP), secure coding patterns, and dive deep into various security tools to enhance and manage the security of JavaScript applications.

Road to Zero Lint Failures: Tackling Code Quality Challenges at Scale
Lint rules enable us to uphold code quality and minimize errors. It can positively impact developer productivity and happiness, especially when working on a massive application with multiple teams working together. But what if your large-scale application contains thousands of lint failures over the many years it has been running in production? This talk will explore actionable strategies for effectively addressing lint failures at scale so that we can again rely on lint rules to ensure consistent code quality and streamline development processes, leading to a more robust and maintainable codebase.

Beyond the browser: Moving forward with a more Declarative Future with WebAssembly
Since its announcement in 2015 and the MVP release in 2017, WebAssembly as a standard has come a very long way. Originally conceptualised to solve the plethora of problems associated with bringing more languages like C++ to the frontend, the WebAssembly movement has gained momentum and how! With applications that go beyond the browser, the Component Model is the direction that the Wasm ecosystem is moving in. What does this mean for us mortals? A more declarative approach while building software, better reusability & portability of the software thus developed, and of course, the ability to bring more languages to the web. In this talk, the speaker will delve into the WebAssembly framework & the component model proposal for by discussing the motivations for their existence. With the help of analogies, the speaker will guide the audience through the various nuts and bolts of the proposal in detail. At the end of the session, the speaker aims to arm the audience with a working knowledge of the component model and resources to pursue further research and get involved in the Wasm community, should they wish to..

Secret Shortcuts of Loading Web Performance
When optimizing loading performance of web apps, everything is easy when we Google a little bit and apply standard optimization techniques like minimizing & compressing files, using tree-shaking, inlining critical CSS, using next-gen image formats, apply caching headers, use server-side rendering etc… But what if, that is not enough and we need to go above & beyond that. That’s where we need to take secret shortcuts, so we can boost the loading time of our app to the speed of light 🚀🚀🚀 This talk has the answer to the question what are secret shortcuts of Loading Web Performance, with a lot of real-life examples in React.

Why don’t the browser’s Dev Tools understand Your Code?
Why do web dev tools know so little about our codebase? DOM inspection is great, but there is much to be gained by also showing us how our code works to produce what the user experiences on the screen. I’ve been working on a product, MightyMeld, that connects the living DOM to the codebase, and the possibilities are enormous. In this talk, I’ll explain why it’s been historically difficult to bridge this gap on the web (despite much prior art for desktop, mobile, and game development). The prevalence of component-based architectures like React is now making such dev tool experiences possible. Bridging the gap between DOM and code unlocks, not only the tightest-loop integration of generative AI possible, but also frees up developers to think about UI on a higher level while building features.
