This document provides an introduction and overview of ReactJS concepts including:
- Features of ReactJS like its component-based architecture and support for ES6
- What transpilers are and examples like Babel and Traceur
- Examples of setting up a basic "Hello World" React app with increasing complexity
- Additional concepts covered include properties, events, lists, conditional rendering, fetching external data and more
Getting started with the reactjs, basics of reactjs, introduction of reactjs, core concepts of reactjs and comparison with the other libraries/frameworks
This document introduces React, describing it as a JavaScript library for building user interfaces by rendering components rather than mutating the DOM directly. It discusses how React uses a virtual DOM for fast re-rendering, building components instead of templates, and the use of JSX syntax to write HTML-like code. Components have state and props, and the whole app re-renders when state changes to guarantee updates.
This document discusses React, Flux, and Redux frameworks. It provides an overview of each:
React is a JavaScript library for building user interfaces using reusable components. It uses a virtual DOM for efficient re-rendering.
Flux is an architecture for unidirectional data flow between actions, dispatcher, stores, and views. Stores hold application state and logic. Actions describe events. The dispatcher routes actions to stores.
Redux takes cues from Flux but with a single immutable state object and pure reducer functions. It is not limited to React and allows functional programming approaches like immutable data and pure functions.
This document provides an introduction to React.js, including:
- React.js uses a virtual DOM for improved performance over directly manipulating the real DOM. Components are used to build up the UI and can contain state that updates the view on change.
- The Flux architecture is described using React with unidirectional data flow from Actions to Stores to Views via a Dispatcher. This ensures state changes in a predictable way.
- Setting up React with tools like Browserify/Webpack for module bundling is discussed, along with additional topics like PropTypes, mixins, server-side rendering and React Native.

Building React Applications with Redux
with Yuri Takhteyev
OVERVIEW
Since React is just a “view framework”, it leaves you with lots of options for how to architect the deeper parts of your stack. The best way to handle those deeper layers is by using Redux – a state container that allows you to write much of your application in the form of pure functions. Using Redux helps you write applications that are much easier to test and understand and to achieve more thorough separation between your views and your business logic. Redux also unlocks the possibility of using amazing tools.
OBJECTIVE
Introduce the audience to Redux, a state container that can be used together with React to achieve sanity deeper down in your stack.
TARGET AUDIENCE
Developers familiar with core React and looking for a better way to architect their applications.
ASSUMED AUDIENCE KNOWLEDGE
Core React knowledge is assumed. Familiarity with basic Flux concepts would help, but I’ll review those quickly.
FIVE THINGS AUDIENCE MEMBERS WILL LEARN
Why pure functions make your code easier to maintain.
How unidirectional data flows help you sleep better at night.
How Redux helps you manage state better via reducers.

This document discusses React component lifecycle methods and the different phases a component goes through: initialization, mounting, updating, and unmounting. It provides details on the purpose and usage of each lifecycle method, including the constructor, componentWillMount, render, componentDidMount, componentWillReceiveProps, shouldComponentUpdate, componentWillUpdate, componentDidUpdate, and componentWillUnmount. The lifecycle methods allow performing actions at specific stages of the component's existence, such as initializing state, integrating APIs, updating based on new props or state, and cleaning up.
The document provides an introduction to ReactJS, including:
- ReactJS is a JavaScript library developed by Facebook for building user interfaces.
- It uses virtual DOM for rendering UI components efficiently. Only updated components are re-rendered.
- Components are the basic building blocks of React apps. They accept input and return React elements to describe what should appear on the screen.
- The main steps to set up a React app are installing React and ReactDOM libraries, adding JSX syntax, and rendering components onto the DOM using ReactDOM.render().
Sharing code in between react components by using render props. HOC and react prop are some of the best ways to share code in react class components.

React Best Practices All Developers Should Follow in 2024.pdfBOSC Tech Labs
Stay ahead with these crucial React best practices for 2024. Learn how to optimize your React applications for performance, maintainability, and scalability.
React (also known as React.js or ReactJS) is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies.
React can be used as a base in the development of single-page or mobile applications, as it is optimal for fetching rapidly changing data that needs to be recorded. However, fetching data is only the beginning of what happens on a web page, which is why complex React applications usually require the use of additional libraries for state management, routing, and interaction with an API.
The document discusses Meteor's Tracker package, which enables reactive programming in Meteor applications. Tracker uses an observer-like pattern to transparently track dependencies between reactive data sources and computations. When a data source changes, Tracker reruns any dependent computations to update the UI or other data reactively. Key aspects of how Tracker works include creating Dependency objects for reactive data, tracking the "current computation", and rerunning computations through Dependency's depend() and changed() methods. Tracker provides a powerful yet simple way to build reactive applications in Meteor without needing expertise in functional reactive programming.
The document provides an overview of trends in the React ecosystem. It introduces React concepts like components, props, state and lifecycles. It also discusses tools like Babel and Webpack. For state management, it covers Redux and MobX. Redux uses a single state tree, pure functions called reducers, and actions to change state. MobX uses observable state and computed values. The document also summarizes routing with React Router, and React bindings for Redux like react-redux and middleware like redux-saga and redux-thunk.
This document provides an overview and introduction to React.js, including:
- React uses components and states, with components being reusable parts of the interface and states allowing components to re-render when data changes.
- JSX allows embedding XML-like syntax in JavaScript and makes code more readable.
- Props are used to pass data between parent and child components, while state stores internal data of a component that may change.
- The document provides examples of building a simple component to track saves or favorites of a home listing as state, and discusses organizing data flow through components.
This document provides an overview and instructions for a web programming course that covers React.js. It includes:
- An announcement about an exam due date and a walkthrough screencast
- Instructions for an assignment to create a responsive grid layout using Bootstrap
- An overview of React.js and how it can efficiently update and render components when data changes
- Steps for getting set up with React, including installing developer tools and packages
- An introduction to React components, properties, state, functions, and refs
- Information on mapping arrays and arrow functions
- Directions for creating a React app using Create React App through Node.js
Redux and context api with react native app introduction, use cases, implemen...Katy Slemon
The document compares Redux and Context API for state management in React Native apps. It discusses the purpose and building blocks of each, provides an example counter app using both approaches, and compares their key differences. Redux is designed for centralized state management while Context API is for passing data through a component tree without prop drilling. Redux uses actions, reducers and a store while Context API uses contexts and providers. The example shows implementing each approach and the document concludes that Redux is better for large complex apps that need precise state management.
ReactCodemod: An automated approach for refactoring class based components to...IRJET Journal
This document describes an automated approach called ReactCodemod for refactoring class-based React components to function components using hooks. It proposes using the jscodeshift API to parse code into an abstract syntax tree (AST), identify code that needs refactoring, transform the AST by manipulating nodes, and regenerate the output code. The key steps are to import required hooks, replace state with useState, add const before class properties, remove references to 'this', replace setState with a setter function, and replace lifecycle methods with corresponding hooks. ReactCodemod aims to save developer time and effort compared to manual refactoring. It provides an architecture including a transform module that runs the refactoring logic on the AST,

It depends not only on how beginner-friendly is, but also what kind of projects you want to work on...
Some people might be surprised to hear that we hold a party last Wednesday since we have organized a lot of parties every month. Oh honey, don’t take things so serious! Life is too short, why don’t we just enjoy it while we could? We don’t live in order to work, but work in order that we might live, right?
Okay, I know I’m a bit off topic. LOL.
Where am I? Oh yes, we partied again. But we did have reasons to celebrate! March 8 is a very big day. It’s International Women’s day which is a day to work toward gender parity. Instead of taking to the streets to demand real policy changes—particularly as women do in some nations where their rights are under threat, in my country the holiday looks remarkably similar to Valentine’s Day, with women receiving flowers and gifts from the men in their lives.
To embrace the monumental contributions of women, there is no reason that my company don’t hold a big fat party.

This is one of three topics of our rst Meteor Meetup on June 4th, 2016 (https://blog.designveloper.com/2016/06/14/meteor-ho-chi-minh-meetup-2016-06-04/). The author is Khang Nguyen, a young talent member of
Designveloper. This is an article on his blog, you can read the original article here (http://nlhuykhang.github.io/javascript/framework/2016/04/29/react-structure-container-component-in-meteor.html).
Introduction
Over the past two months, I have been working on an interesting project at my company which is supposed to be a very big one. So at rst, as a team leader and core maker, I spent quite a lot of time to nd a good starting
point, I meant stuff like how to structure the project, which frontend stack to use, how that stack connects to server, how to set up and bring all those things together, etc, to satisfy all the project’s requirements.
Finally, I settled down with Meteor for backend, React for frontend, and Vanilajs ES6 MVC for the app extension (this was the most interesting part of the project. I will talk about it in another blog). At rst things went well and
smooth. Needless to say that React was so amazing that I completely changed my thoughts when programming.
But soon later, since this was the rst time I had really built such a big project with React, things started to get messy. I encountered a problem that every big project coded in React had. Hence, I have this post written to let
you know what problem was and how I attempted to solve it.
Prerequisites
React is introduced to be simple and very easy to learn for beginners. That is de nitely true, but frankly speaking, it takes quite an effort to come up with when you are at beginner level.
Unfortunately, this post is not aimed for beginners because I am writing about experience I learned in a big project, not just the way to use React for Meteor project. So it may require readers to have the following knowledge
to understand what I am going to write:
React container component (https://goo.gl/xxGHnu)
React unidirectional data ow (http://redux.js.org/docs/basics/DataFlow.html)
React Mixins (http://goo.gl/mDj9fO)
React in Meteor 1.2 (https://goo.gl/V5v271)
Ramdajs (http://goo.gl/x2Sblm)
The problem that I encountered
I can summary the problem with only one word, and that is maintainable.
Follow the unidirectional data ow principle, I created a container component for each routes for the problem. This component is in charge of almost every logic stuff for the route it is being used for. E.g. it takes care of
subscribe data/call methods from Meteor server, is a middle man for its children components talking to one another. With all those missions, soon it becomes a very big and fat guy.
The le in which I coded the container component in was about 700 lines when I just nished about half of the work. This was clearly unacceptable. If I had ignored this problem and kept coding to get the job done fast, it
would have been a nightmare for maintainer/debugger.
Knowing that this was my company’s main project, meaning that my colleagues and I would be working on it for years, I stopped coding features and started reviewing the code.
First attempt
I looked at all the container’s functions and realized that they could be categorized into four groups:
Component’s must-have functions: getInitialState, getMeteorData, render, etc…
Handler functions: all event handlers for all container’s children components
Helper functions: functions to help get necessary data for container’s children components based on container props and state. There functions are merely pure functions, they take input and produce output without
touching the container state or talking to Meteor server.
Logic functions: functions to modify the component state, call methods from server. These functions are called by event handlers in response to user actions.
With this model in mind, I decoupled the last three groups’ functions into three separate les and imported them back in the container through mixins.
3. The directory of the container looked like this:
root
| ...
|---...
|---poppi:client-container-example-component
|---client
|---components
|---subcomponent1
| ...
|---subcomponent2
| ...
| ContainerExample.jsx
| ContainerExampleContainer.jsx
| ContainerExampleHandlers.js
| ContainerExampleHelpers.js
| ContainerExampleLogicFuncs.js
| package.js
|---...
And also the code of the container
ContainerExampleContainer = React.createClass({
mixins: [
ReactMeteorData,
ContainerExampleHandlers,
ContainerExampleHelpers,
ContainerExampleLogicFuncs,
],
getInitialState() {
...
},
getMeteorData() {
...
},
render() {
...
},
});
My container looked much better. It became a thinner and more handsome guy. When you need to nd a function, I recommend this decoupling technique for a faster and more semantic solution. However, it would be even
better if I did not face a hurdle
Push it a bit further
Even though I separated all functions into 3 different mixin les, I had not had any idea on where to put each function yet. All the time I had to check those 3 functions to identify the appropriate function places. This was time-
consuming and I needed a more ef cient way. The only way that I thought of at that time was looking at the function calling statement.
After thinking for a while, I fell back to the basic technique widely in js: “namespace”. I grouped all the functions under a namespace obj inside the mixin obj. My three mixin le then became:
4. // ContainerExampleHandlers.js
ContainerExampleHandlers = {
Ha: {
clickHandler() {
this.L.test1();
return;
},
},
};
// ContainerExampleHelpers.js
ContainerExampleHelpers = {
He: {
getData(state) {
return {
state
};
},
}
};
// ContainerExampleLogicFuncs.js
ContainerExampleLogicFuncs = {
L: {
test1(param1) {
const data = this.He.getData(param1);
this.setState({
...data,
});
},
test2(param2) {
Meteor.call('test2', param2);
}
},
};
By just looking at the calling function statement, I knew exactly where these functions came from. This is extremely useful and ef cient when working on a big and complicated project.
But unfortunately I still could not enjoy the fantasy of this technique, because the scope inside all functions was wrong.
So I had to bind their contexts to the right ones.
Ramda to the rescue
The binding process could be done easily by a for-in loop inside the getInitialState function of the container. But it required more than that and I needed a more uni ed, modern, handy and understandable way, also shorter
one to use in this big project. Luckily, the rise of Ramda recently got my attention and turned out to be the best t for my requirements.
Finally I came up with this binding function:
// bindMixinFunctions.js
bindMixinFunctions = R.converge(function(keys, values, ctx) {
const bindValues = R.map((val) => R.bind(val, ctx), values);
return R.zipObj(keys, bindValues);
}, [
R.flip(R.keys),
R.flip(R.values),
R.identity
]);
5. And use it in action:
ContainerExampleContainer = React.createClass({
mixins: [
ReactMeteorData,
ContainerExampleHandlers,
ContainerExampleLogicFuncs,
ContainerExampleHelpers,
],
getInitialState() {
const thisBindMixinFunctions = bindMixinFunctions(this);
this.He = thisBindMixinFunctions(this.He);
this.Ha = thisBindMixinFunctions(this.Ha);
this.L = thisBindMixinFunctions(this.L);
...
},
...
});
After all the hard work, I was able the enjoy the result. The code ran smoothly as expected and was much better in term of structuring, semantic and maintainable criteria. I did not have to worry about later
maintaining/debugging process any more.
Conclusion
It may be a bit tedious to write all this code and structuring before implementing the real features. But for me it is really worthy, this pattern actually saves me a lot of time and effort trying to gure out where a function is,
what it does, how it connects to others functions.
If you are still using React version 0.14.3 in Meteor 1.2, which is possible if you already worked in these frameworks, I hope that you will get bene ted from my pattern and take the best of it.
If you are going to set up a new project with the latest version of React and Meteor and decide to implement this pattern, I would love to hear how you do that.
