Building React Applications with Idiomatic Redux (Egghead.io)
This repo contains notes from Dan Abramov's second Redux course on Egghead.io.
01. Simplifying the Arrow Functions
See how ES6 features can be used to clean up arrow functions even more. Video
02. Supplying the Initial State
We will learn how to start a Redux app with a previously persisted state, and how it merges with the initial state specified by the reducers. Video
03. Persisting the State to the Local Storage
We will learn how to use store.subscribe() to efficiently persist some of the app’s state to localStorage and restore it after a refresh. Video
04. Refactoring the Entry Point
We will learn how to better separate the code in the entry point to prepare it for adding the router. Video
05. Adding React Router to the project
We will learn how to add React Router to a Redux project and make it render our root component. Video
06. Navigating with React Router <Link>
We will learn how to change the address bar using a component from React Router. Video
07. Filtering Redux State with React Router Params
We will learn how adding React Router shifts the balance of responsibilities, and how the components can use both at the same time. Video
08. Using withRouter()
to Inject the Params into Connected Components
We will learn how to use withRouter()
to inject params provided by React Router into connected components deep in the tree without passing them down all the way down as props.
Video
09. Using mapDispatchToProps()
Shorthand Notation
We will learn how to avoid the boilerplate code in mapDispatchToProps()
for the common case where action creator arguments match the callback prop arguments.
Video
10. Colocating Selectors with reducers
We will learn how to encapsulate the knowledge about the state shape in the reducer files, so that the components don’t have to rely on it. Video
11. Normalizing the State Shape
We will learn how to normalize the state shape to ensure data consistency that is important in real-world applications. Video
12. Wrapping dispatch()
to Log Actions
We will learn how centralized updates in Redux let us log every state change to the console along with the action that caused it. Video
13. Adding a Fake Backend to the Project
We will learn about fake backend module that we will be using throughout the next lessons to simulate data fetching. Video
14. Fetching Data on Route Change
We will learn how to fire up an async request when the route changes. Video
15. Dispatching Actions with the Fetched Data
We will learn how to dispatch a Redux action after the data has been fetched and recap how to do it when the route changes. Video
16. Wrapping dispatch()
to Recognize Promises
We will learn how to teach dispatch()
to recognize Promises so that we can move the async logic out of the components into asynchronous action creators.
Video
17. The Middleware chain
We will learn how we can generalize wrapping dispatch()
for different purposes into a concept called “middleware” that is widely available in the Redux ecosystem.
Video
18. Applying Redux Middleware
We will learn how to replace the middleware we wrote and the custom code we used to glue it together with the existing core and third party utilities. Video
19. Updating the State with the Fetched Data
We will learn how moving the source of truth for the data to the server changes the state shape and the reducers in our app. Video
20. Refactoring the reducers
We will learn how to remove the duplication in our reducer files and how to keep the knowledge about the state shape colocated with the newly extracted reducers. Video
21. Displaying Loading Indicators
We will learn how to display the loading indicators while the data is being fetched. Video
22. Dispatching Actions Asynchronously with Thunks
We will learn about “thunks”—the most common way to write async action creators in Redux. Video
23. Avoiding Race Conditions with Thunks
We will learn how Redux Thunk middleware lets us conditionally dispatch actions to avoid unnecessary network requests and potential race conditions. Video
24. Displaying Error Messages
We will learn how to handle an error inside an async action, display its message in the user interface, and offer user an opportunity to retry the action. Video
25. Creating Data on the Server
We will learn how to wait until the item is created on the server, and update the corresponding local state. Video
26. Normalizing API Responses with normalizr
We will learn how to use normalizr to convert all API responses to a normalized format so that we can simplify the reducers. Video
27. Updating Data on the Server
We will learn how to wait until the item is updated on the server, and then update the corresponding local state. Video
