You have a handle on the basics: components, props, state. On the other hand, tackling a huge project that does everything is not a great idea either.
The best thing you can do at this stage is to choose simple and small apps to build. Aim for quantity over quality. Drop your email in the box and I'll send you 5 lessons over 5 days covering the basics of props, state, JSX, and fetching data, plus weekly ish more advanced articles on React and Redux.Asal 24 fanproj
I suggest using Create React App to bootstrap these projects, but you can also use CodeSandbox if you want something quick and easy. Focus on getting the functionality working, and then work on CSS.
Or, alternatively, learn some CSS first, and apply it as you go! A great way to improve your CSS skills is by recreating apps that you know and love, pixel by pixel. In other words, if I were trying to recreate Twitter for CSS practice, I would not worry about the React side of things at all: keep it entirely static until it looks right, and then start adding interactivity.
Once you have a single SocialCard component rendering, try making a list of them with some fake data. You can see how this app starts off simple, but can be expanded and customized to increase the challenge and learn specific new skills. You probably already know how these work.
Add, subtract, multiply, divide… Clicking the numbers or the operations should perform the action. For added challenge, respond to keyboard input too. Spend a little time thinking about how the state will be represented.
Do you need to store more than just the numbers on the display? When you type a new number, does it replace the display with that number, or append it to the end? Add some snapshot tests with Jest to test that the calculator works correctly. Both are good practice projects. It has been said that all web apps are basically just lists.
This app will give you some practice with lists of components that are a little more complicated than todos. Use static data at first, and then if you want a little more of a challenge, fetch stories from their API.
My advice? Learn one thing at a time. Then I might build a static plain Hacker News, and then once that was working, integrate it with Firebase. To keep the scope small, just focus on implementing the list of issues, and ignore the stuff in the header search, filtering, stars, etc. You could use static data for this too. Then add a pagination control to allow navigating through the entire list of issues.For example, all of the Redux code related to the users piece of state lives in the same file rather than being scattered across different typesactionsand reducer folders throughout your app.
These will serve as the two main parts of Redux state. Remember to give it the --typescript flag when you create the project. We can define our UserState type and a couple action creators: login and logout. A reducer takes the state and an action and produces a new state. We know we can type both our state argument and the reducer return value as UserStatebut how should we type the action we pass to the reducer? Our first approach will be taking the ReturnType of the login and logout action creators.
Unfortunately, we have a couple problems. It turns out we can solve this issue by using Typescript function overloads and generics. The type created by this function will be a generic that extends string. The payload will be a generic that extends any. We can now create our products module, which will have the ability to return thunks from its action creators.
The product piece of our state will be a litte more complicated. Our setTimeout function is simulating a fetch without having to actually perform a fetch. We now need to register the productsReducer with our rootReducer. We now have access to props.
One wrinkle is when we want to map in an action creator that returns a thunk. We can use map in our loadProducts action creator as an example. Not too bad to get the state management goodness of Redux with the type safety of Typescript. If you want to see a similar app in action, please check out the associated github repo.

However, the docs can't cover everything. Happily, there are many other great resources available for learning Redux. We encourage you to check them out. Many of them cover topics that are beyond the scope of the docs, or describe the same topics in other ways that may work better for your learning style. This page includes our recommendations for some of the best external resources available to learn Redux.
The linked Github repo contains notes and transcriptions of the videos. Includes lessons on store initial state, using Redux with React Router, using "selector" functions, normalizing state, use of Redux middleware, async action creators, and more.

All the jargon words such as reducers, state, actions are very well defined by him. Redux may be seem difficult at the start but Traversy paves out a perfect route for beginners. Looks at the benefits of using Redux, how it differs from MVC or Flux, and its relation to functional programming. What Does Redux Do? It explains how to use Redux and React-Redux, by first showing a React component that stores a value in its internal state, and then refactoring it to use Redux instead.
Along the way, the article explains important Redux terms and concepts, and how they all fit together to make the Redux data flow work properly. Tutorials that teach Redux concepts by building projects, including larger "real-world"-type applications. Written by Redux co-maintainer Mark Erikson. Covers topics like managing relational data, connecting multiple components and lists, complex reducer logic for features, handling forms, showing modal dialogs, and much more. Very well written, with some useful diagrams as well.
How to use Redux in ReactJS with real-life examples
Well-written, covers many concepts, and very easy to follow. Let's Write Redux! Covers the concept of "selector functions", how to use Reselect's API, and how to use memoized selectors to improve performance. A useful extension to the idea of normalized data.
Stack Overflow: Why do we need middleware for async flow in Redux? What the heck is a "thunk"? What is the right way to do asynchronous operations in Redux?
What's So Great About Redux? Very worth reading. Additional discussion on Reddit. The RealWorld project also includes many other implementations of the front and back ends of the site, specifically intended to show how different server and client implementations of the same project and API spec compare with each other.
It extends the original by using Redux and Redux Saga instead of local state, as well as React Router v4, styled-components, and other modern standards. Based on the React-Boilerplate starter kit. Actually plays MP3s, and lets you load in local MP3 files.
Does a great job of explaining the pros, cons, and tradeoffs of many approaches to using Redux. Personally recommended by Redux co-maintainer Mark Erikson. Why do I need store enhancers?These are repositories that you copy and modify to create your own React app. To get started with most of these, you would clone the repository and then start making modifications.

I've wrapped the action methods in an alertActions object at the top of the file so it's easy to see all available actions at a glance and simplifies importing them into other files. The implementation details for each action creator are placed in the below functions. Contains Redux action creators for actions related to users.
Public action creators are exposed via the userActions object at the top of the file and function implementations are located below, I like this structure because you can quickly see all of the actions that are available. Most of the actions for users are async actions that are made up of multiple sub actions, this is because they have to make an http request and wait for the response before completing.
Async actions typically dispatch a request action before performing an async task e. To keep the code tidy I've put sub action creators into nested functions within each async action creator function. Putting the sub action creators into nested functions also allows me to give them standard names like request, success and failure without clashing with other function names because they only exist within the scope of the parent function.
The way it checks if the user is logged in is by checking that there is a user object in local storage. While it's possible to bypass this check by manually adding an object to local storage using browser dev tools, this would only give access to the client side component, it wouldn't give access to any real secure data from the server api because a valid authentication token JWT is required for this.
It could be used for any other constants in the project as well, it doesn't have to be only for redux action types. I decided to put redux action constants into their own files rather than the same files as redux actions to simplify my redux action files and keep them focused on one thing.
The alert constants object contains the redux alert action types used to display and clear alerts in the react application. The user constants object contains the redux user action types that can be dispatched in the react application, async actions that perform http requests involve a request followed by a success or error response, so each of these three steps is represented by a redux action.
The helpers folder contains all the bits and pieces that don't fit into other folders but don't justify having a folder of their own. If the user isn't logged in an empty object is returned. The fake backend is used for running the tutorial example without a server api backend-less. It monkey patches the fetch function to intercept certain api requests and mimic the behaviour of a real api by managing data in browser local storage.
Any requests that aren't intercepted get passed through to the real fetch function. The history is a custom history object used by the React Router, the reason I used a custom history object instead of the built into React Router is to enable redirecting users from outside React components, for example from the user actions after successful login or registration.Percy sees annabeth scars fanfiction
The redux store helper calls createStore to create the centralized redux state store for the entire react application. SUCCESS action is dispatched, the reducer updates the alert state to an object with type: 'alert-success' and message: action. The redux authentication reducer manages the state related to login and logout actions, on successful login the current user object and a loggedIn flag are stored in the authentication section of the application state.
The redux registration reducer manages the registration section of the application state, as you can see there isn't much to it, on registration request it just sets a registering flag set to true which the RegisterPage uses to show the loading spinner. On register success or failure it clears the registration state. The redux users reducer manages the users section of the application state which is used by the HomePage to display a list of users and enable deleting of users.
CRUD operations. Services can also have methods that don't wrap http calls, for example the userService. I like wrapping http calls and implementation details in a services layer, it provides a clean separation of concerns and simplifies the redux actions and other modules that use the services. The user service encapsulates all backend api calls for performing CRUD operations on user data, as well as logging and out of the example application.
The service methods are exported via the userService object at the top of the file, and the implementation of each method is located in the function declarations below.
