Top ideas

Can Redux be used with server-side rendering (SSR)?

Yes, Redux can be used with server-side rendering (SSR). You can create a Redux store for each request, dispatch actions to fetch data, and then pass the serialized state to the client for hydration. However, whether to use Redux for SSR depends on the specific needs of your application.

What are atomic changes in the context of a MonoRepo?

Atomic changes refer to the ability to make changes across multiple projects within a MonoRepo in a single commit. This ensures that all interdependent components are updated together, minimizing the risk of compatibility issues.

Can React Server Components be integrated into React Native?

Yes, React Server Components can potentially be integrated into React Native. Although primarily used in web contexts, their integration into mobile can help manage component updates and reduce data usage by only streaming necessary components.

What is the new event loop in React Native?

The new event loop in React Native is part of the new architecture that allows for synchronous communication between JavaScript and native layers, improving performance and aligning React Native more closely with React DOM.

How has Redux evolved over time?

Redux has evolved from being a minimal library requiring a lot of boilerplate code to Redux Toolkit, which simplifies common tasks like creating stores and reducers, and includes features like RTK Query for data fetching. Modern React features like hooks have also been integrated into Redux.

How does decentralization impact modern software architecture?

Decentralization is crucial in modern software architecture as it involves multiple teams, often spread across different locations, requiring a focus on more than just technology choices like microservices versus monoliths.

What is HTTP pipelining in Undici?

HTTP pipelining in Undici allows sending multiple requests in a single connection without waiting for the previous response, improving throughput.

Can developers forget about manual memoization with React Compiler?

For most developers, enabling React Compiler may be sufficient, allowing them to forget about manual memoization. However, those needing to optimize every millisecond may still need to use manual memoization techniques.

Why is optimizing for users at the margins important?

Optimizing for users at the margins, who often use lower-end devices, can significantly improve engagement and business outcomes, as these users make up a large part of the market.

What challenges are associated with implementing React Server Components in React Native?

Challenges include managing different versions of the app and server components, handling app updates without full store reviews, and ensuring that native user experience remains consistent. Technical hurdles also involve configuring server-side operations within a mobile context.

The Talk discusses the balance between flexibility and consistency in design systems. It explores the API design of the ActionList component and the customization options it offers. The use of component-based APIs and composability is emphasized for flexibility and customization. The Talk also touches on the ActionMenu component and the concept of building for people. The Q&A session covers topics such as component inclusion in design systems, API complexity, and the decision between creating a custom design system or using a component library.

HTTP/3 Performance for JS Developers

HTTP 3, also known as H3, is the latest version of the HTTP protocol with new performance-related features. Enabling HTTP 3 requires minimal effort and provides significant benefits, but limits fine-grained control over performance features. Zero RTT has limitations due to security reasons and restrictions on allowed requests. Resource loading and prioritization in HTTP 3 have some problems, as browsers may not agree on resource importance. Fetch priority allows fine-grained control over resource loading order, and resource discovery can be improved with 103 Early Hints. Web transport provides low-level access to QUIC and HTTP3 features for real-time use cases.

This Talk discusses the benefits of microservices and containers for building CI-CD pipelines. It explains how container technology enables portability and scalability. The challenges of microservices include network communication and testing in isolation. The Talk introduces Tacton, a cloud-native CICD pipeline for Kubernetes, and highlights the use of GitOps and Argo CD. It also discusses the importance of maintaining referential integrity between microservices and the evolving role of operators in the DevOps world.

Alexander Johansson

The creator of tRPC

Alex introduces tRPC, a toolkit for making end-to-end type-safe APIs easily, with auto-completion of API endpoints and inferred data from backend to frontend. tRPC works the same way in React Native and can be adopted incrementally. The example showcases backend communication with a database using queries and validators, with types inferred to the frontend and data retrieval done using Prisma ORM.

The Good, The Bad, and The Web Components

Eleventy (11ty) Creator

Web Components are a piece of reusable UI enabled by web standards and built into the web platform. They offer the potential for faster component initialization and less library overhead. Web Components can be created from scratch and utilized with existing component libraries. Shadow DOM and Declarative Shadow DOM provide benefits such as scoped CSS and server-rendered components. The tradeoff between not repeating oneself and achieving full server-side rendering support is discussed. User experience is deemed more important than developer experience.

Today's Talk introduces React Snots, a new way of composition for design systems. The configuration way provides flexibility but can lead to uncontrolled use cases and wrong patterns. React Slots RFC was created to address the limitations of React's support for web components and slots. It introduces createHost and createSlot APIs to enable component composition and solve previous problems. React Slots RFC allows for flexible component styling and the creation of complex structures without rendering them to the browser.
