React gsg presentation with ryan jung & elias malikLama K Banna
React is a client-side JavaScript library for building user interfaces that is made and open-sourced by Facebook. It uses a virtual DOM for fast rendering and reusable components to build up the UI. Components can have their own state that causes re-rendering when updated. Events are handled through callbacks. JSX allows writing HTML-like code mixed with JavaScript.
Managing state across complex apps with many interacting components can be challenging. Flux and Redux address this with a single source of truth store and reducer functions that update state immutably in response to actions. Side effects like API calls require middleware like thunks, sagas, or API-specific middleware to isolate impure logic from pure reducers.
This document provides an introduction and overview of React and Redux. It begins with an introduction to key React concepts like components, props, state, and the virtual DOM. It then covers Redux, including actions, reducers, stores, and using Redux with React. Other topics include React Native, server-side rendering, routing with React Router, testing, and resources for learning more. The document aims to give the high-level essential information about React and Redux.

React Native allows developers to build native mobile apps using JavaScript and React. While it provides benefits like using React for both web and mobile, allowing for code reuse, there are also challenges to using it in production. It is easy for web developers to use initially but documentation is poor and updates can cause breaking changes. Performance has not been an issue yet but native apps are generally faster. While the community is active, third party packages can introduce bugs and the build can sometimes break, especially on Android. Overall, React Native can be used for production apps if challenges around updates and crashes are addressed.
This document provides an overview and introduction to React, a JavaScript library for building user interfaces. It discusses why React is used, how to set up a React environment, core React concepts like components, props, state, lifecycles and events. It also introduces React Native for building native mobile apps with React. The document emphasizes learning React through hands-on examples and practice.

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It uses virtual DOM which improves performance and can render on both client and server. React encourages a component-based approach where UI is broken into independent reusable pieces that accept external data through properties. Components manage their own state which allows the UI to update over time in response to user input. This makes React code more predictable and easier to debug than traditional two-way data binding.

14. 14
Growing JavaScript codebase since 2009
As of 2012
Large, complex JavaScript application
Homebrew/vanilla
Time to choose a framework!
Now we had
Object-oriented, non-global
Standard ways to do common actions

Hard to reason about data flow, messaging between components
Hard to reason about where state lived
Hard to reason about composing complex components and UIs
etc. etc.
JS @ CONDUCTOR: A BRIEF HISTORY
19. 19
Flow of data and communication between components is more coherent
State management is clearer
Handling of state changes is more predictable
Best practices and patterns around composing components and Uis
etc. etc.
WHY REACT/REDUX?

Easy!
All frontend engineers
drop everything and stop building and
enhancing client-facing features
until we’ve completely replaced hundreds
of thousands of lines of JS code! 👍 👍

THE (REAL) PLAN FOR MIGRATING TO REACT/REDUX
”…gradually create a new
system around the edges
of the old, letting it grow
slowly over several years
until the old system is
strangled.”

Where it gets tricky
THE STRANGLER PATTERN ON THE FRONT END
33. 33
Where it gets tricky
1. “As a user, I see a fancy new version of some common component”
Rebuild it in React 👍
New component needs to live on Backbone screens 😱

2. “As a user, I see a fancy new/updated screen containing some old
common components”
Build screen in React/Redux 👍
Old backbone components live on that screen 😱
THE STRANGLER PATTERN ON THE FRONT END
35. 35
Straightforward application of Strangler Pattern in UI:
Building new or updating old screens to 100% React/Redux
Having 100% React/Redux screens live in the same application as 100%
Backbone/Marionette screens

What we needed:
1. Ability to wrap React Components in Backbone Views
2. Ability to wrap Backbone views in React Components and have them
interact with Redux
THE STRANGLER PATTERN ON THE FRONT END
38. 38
We need a Backbone-style render method
React Component’s render method returns React elements intended
for the Virtual DOM
Backbone View’s render method directly modifies a DOM element
We need it to be easy so people use it!
WRAPPING REACT COMPONENTS IN BACKBONE VIEWS
44. 44
Three things to consider about wrapped Backbone views:
1. They will render HTML directly to the DOM, which is not consistent
with React Component.render
2. They may be stateful, and therefore are not disposable, i.e. must not
be re-instantiated
3. They may need to affect shared state, i.e. dispatch Redux actions

Anecdotally: most engineers using R/R are saying they are faster, more
confident about quality, less frustrated
