#react hooks

This Talk introduces the concept of being a 'React bad boy' by ignoring best practices and optimizing React rendering. It explains how to avoid unnecessary rerenders using React.memo and React DevTools. It also covers advanced techniques like isolating state changes and lazy loading hooks. The Talk explores reducing component rerenders using Svelte stores and optimizing with swap stores in Redux. These techniques improve React performance without the need for major refactors or rewrites.

The Talk discusses the use of the Use hook in React and its ability to be used conditionally. It explains the concept of the fiber tree and how hooks values are stored in memory. The Talk also delves into the conditional use of useContext and how it differs from useState. It explores the process of updating context values and optimizing context rendering. The role of the provider in managing context values and rendering is emphasized.

Capacitor is a powerful tool built by Ionic that allows web applications to be compiled into native iOS and Android projects. It comes with a set of plugins, including the camera plugin, and has a React hooks package for seamless integration with React applications. The Talk includes a demo showcasing the camera hook button and the rendering of selected photos. The presenter emphasizes the use of useEffect and useState for additional functionality. The Talk concludes with a mention of the Capacitor community and gratitude for attending.

The Talk covers topics such as React memo compiler, use memo and use callback, building custom hooks, and the benefits of using use ref. It also explores the similarities between use memo and use ref, and the use of React Memo for preventing re-renders and optimizing expensive calculations. The speaker also shares personal information and contact details.

This Talk introduces hook state as a flexible and simple state management solution for React. It demonstrates how hook state can be used for global state management, as well as for managing state within individual components. The speaker highlights the ease of using hook state for tasks such as adding, updating, and removing tasks. The conclusion encourages further exploration of hook state for efficient state management in React applications.

This talk explores how useState works under the hood and why it's important to understand. It addresses the common confusion around the callback to setState and provides insights gained from exploring React hooks source code. Knowing how useState works is important for learning patterns, debugging, and gaining confidence in our code. React manages the current value of hooks in a linked list and performs updates sequentially. React optimizes rendering by caching computations and performing shallow renders when the state doesn't change.

The discussion explores the separation of concerns between logic (Model) and UI (View) and how React hooks are a great abstraction model that help achieve that.
We'll start with designing a component's API (in a top down approach), then dive deeper to explore how to implement this API, while maintaining a good separation of concerns.
We'll create custom React hooks to implement the Model and React components for the UI. Both expose self-documenting APIs and are completely decoupled from each other.
To demo this approach, we'll create a simple Toggler component (a UI component that allows going back and forth in an array of values).Towards the end, we'll explore the benefits, focusing on testing these decoupled units in isolation.

The Talk at React Summit explores the use of useEffect in React and its psychological effects. It delves into the concept of component life cycles and the flexibility of useEffect. The Talk also discusses the use of refs for mounting and unmounting components, as well as the cleanup effects of the return function. It highlights the importance of understanding when and how useEffect runs, and provides examples of using useEffect in different scenarios.

This Talk provides an introduction to React Staytools, explaining how to use the state and setState function to update a counter. It also delves into the inner workings of React rendering, discussing the update queue and re-rendering conditions. The Talk concludes by mentioning the different modes of updating and triggering re-renders in React, and encourages further exploration of the source code and discussion in Discord.
