Create a slide comparing server-side data fetching (using React Server Components/Route Handlers) and client-side data fetching (using SWR/React Query). The slide should highlight the pros and cons of each approach, focusing on performance, caching, UX, and when to use each method. Include code examples for both server-side and client-side fetching. The design should be clean and modern with a clear visual separation between the two approaches. Use animations to emphasize key points and comparisons.
Title: introduce the split between server fetching in React Server Components/route handlers and client-side fetching with libraries.
Point to the left column first. Explain that server fetching runs on the server, can stream HTML, benefits SEO, and leverages HTTP caching and ISR out of the box. Walk through the tiny RSC example.
Move to the right column. Explain client fetching with SWR/React Query excels at per-user state, revalidation on focus, and optimistic updates. Walk through the short SWR example.
Shift to the comparison row. Performance favors server for initial load and SEO; show the check on Server. Caching can live in both places: server for shared/public and ISR, client for per-user cache; highlight both checks. UX favors client for optimistic and live updates.
Conclude with the bottom chips: when to use each. Server for SEO/static, shared data, edge/streaming. Client for interactive views, user-specific data, and optimistic UX.

Frequently Asked Questions
What are the main differences between server-side and client-side data fetching in React?
Server-side fetching (with React Server Components or Route Handlers) fetches data on the server before sending HTML to the client, resulting in fast initial load times and improved SEO. Client-side fetching (with libraries like SWR or React Query) fetches data in the browser after the initial render, enabling features like optimistic updates and real-time data synchronization. Server-side fetching is generally preferred for static content and initial data loads, while client-side fetching excels in interactive applications with dynamic updates and user-specific data.
When should I use SWR or React Query for data fetching?
SWR and React Query are excellent choices for client-side data fetching in React applications when you need features like optimistic updates, revalidation on focus, caching, and background updates. They simplify complex data fetching logic and improve the user experience by keeping the UI responsive and up-to-date. Use these libraries when user interaction and real-time data are crucial to your application.
How do React Server Components improve data fetching performance?
React Server Components allow data fetching to happen on the server, reducing the amount of JavaScript sent to the client. This leads to faster initial load times, especially on mobile devices or slower networks. Server components can also stream HTML, providing a progressive loading experience and further enhancing perceived performance. Additionally, server-side fetching allows for better SEO as search engines can easily crawl and index the pre-rendered content.
Create a slide about React components, focusing on props, state, and the concept of pure render. The slide should explain how function components work with props as input and JSX as output. It should also differentiate between props and state, highlighting that props are external and immutable while state is internal and can trigger re-renders when updated. Emphasize the importance of pure render, where the same props and state always produce the same UI, avoiding side effects during render. Include a code example demonstrating a simple component with props, state, and a button that updates the state. Visually, the slide should have a title, a short description of pure render, a list of key concepts (props in, JSX out; state updates trigger re-renders; pure render = same input, same output), and the code example. Use animations to make the content appear dynamically. The speaker notes should reinforce these concepts and provide a detailed explanation of the code example.
Create a slide visualizing a four-step project workflow: Create Project, Add Sources, Configure Rules, and Review & Publish. Emphasize micro-interactions and callouts at each step. For instance, 'Create Project' should suggest a clear, short name. 'Add Sources' shows a sample dataset in its empty state. 'Configure Rules' has inline validation. 'Review & Publish' blocks publishing if there are critical errors. After these steps, introduce a branching choice for setup: Manual or Import config. Manual setup should be described as guided with defaults, good for small teams, and offer a tip to pre-fill from the last project. Import config allows JSON/YAML upload with a dry-run and checksum check. The overall flow should convey a smooth, efficient process from project creation to publishing, with options for different team sizes and technical levels.
This slide summarizes key learnings and next steps after a project iteration. It's designed for a presentation to stakeholders or a team, aiming to transparently share successes, challenges, and the future roadmap. The slide visually separates learnings and next steps into two columns. Learnings are categorized with icons representing positive, negative, and unexpected outcomes. Next steps are outlined per quarter, highlighting key goals like design system finalization, onboarding revamp, performance enhancement, and accessibility improvements. Finally, a call to action encourages the audience to connect for further discussion.
Create a slide about React performance optimization patterns, including memoization, virtualization, selective re-renders, splitting components, and measuring performance. Provide code examples for memoization and virtualization using React.memo, useCallback, and react-window. Include a tip to prioritize coarse-grained optimizations over micro-optimizations. The target audience is React developers. The slide should have a title, short descriptions of each pattern, a code snippet, and visual cues like icons and color highlights.
This slide explains the importance of keys in lists, the difference between controlled and uncontrolled inputs in React forms, and strategies for scaling form management. It covers how keys preserve identity and state in dynamic lists, ensuring smooth updates. The slide differentiates between controlled inputs, where React state manages values, and uncontrolled inputs, where the DOM holds state. It also touches on using form libraries and schema validation for complex forms with nested fields, arrays, and asynchronous validation rules. The code example demonstrates a controlled input, while the mock form visualizes the concept. The goal is to provide viewers with a clear understanding of these concepts to build efficient and scalable React forms and lists.
Create a slide about choosing the right state management solution in React applications. It should guide developers on when to use local state, Context, or an external store. Explain the trade-offs of each approach and suggest popular external store libraries like Redux Toolkit, Zustand, and Jotai. The slide should be visually appealing and easy to understand. Include speaker notes with detailed explanations of each state management approach.
