#ContextAPI

[asadmukhtarr]

State management is one of the most critical aspects of building React applications, especially as apps scale and become more complex. React provides several tools and libraries to handle state management, each with its strengths and weaknesses. Three popular choices are Redux, Context API, and Recoil.

In this guide, we will compare these three state management solutions, discussing their key features, pros, and cons, helping you choose the right one for your project.

React Navigation 5 Authentication Flow

React Navigation 5 Authentication Flow

In this blog we are going to see how we can integrate Authentication Flow in React Navigation 5. I am going to cover all the points which is necessary in the integration. Because I personally face many problems regarding this implementation. I am using Context API for this. So before starting the blog we should know about Context API. What is Context API in React? The React Context API is a way…

Redux and Context API with React Native App: Introduction, Use Cases, Implementation, and Comparison

If you’re having a Javascript background then you might be familiar with the terms Redux and Context API. And probably, you might have come across so many blogs that debate on which is better- Redux vs Context API. I assumed the same unless I realized it’s not!

After reading a bunch of blogs, I concluded the purpose of both the tools and how different they are from each other. If you aren’t aware yet, don’t worry this tutorial will help you understand the use cases of both tools with a basic demo example. Here, we will build an app using both approaches and discuss them.

Let’s get started, then!

Tutorial Goal

Understanding Redux and Context API

Comparing the working of Redux and Context API

Exploring the purpose and use case of Redux and Context API

A demo application using Redux and Context API approach

Redux: Introduction and Building Blocks

According to documentation-

Redux is a pattern and library for managing and updating application state, using events called “actions”. It serves as a centralized store for state that needs to be used across your entire application, with rules ensuring that the state can only be updated in a predictable fashion.

The documentation clearly mentions that redux is for “managing state” and understanding how the state is updated.

Use Cases of Redux

The primary goal of redux, as mentioned in the doc, is to manage and keep track of the state.

Keeping your state management logic separate from the user interface layer

Faster logic debugging

Redux is mainly used to manage the state of React applications in a centralized place where to access the state anywhere in the application. Technically, The concept of Redux is based on Flux architecture and this concept isn’t restricted to React apps; there are implementations in different technologies, as well (e.g. NgRx for Angular). But Redux is particularly implemented with React.

Packages needed

redux: For the functions like createStore(), combineReducer() etc.

react-redux: For the functions like connect() etc.

Building Blocks of Redux

It consists of mainly four building blocks:

1. Reducer: These are functions with state and actions passed in as arguments. It contains “action.type” in switch cases which returns the changed value. It optionally accepts the payload (generally created in a separate file known as reducers.js)

2. Store: Store is the collection of all data. You can pass it to the provider.

3. Provider: A React component that accepts store as an argument (usually created in index.js)

4. Actions: Functions that provide/return action type and payload to the dispatcher which will further call the respective reducer (generally created in a separate file known as actions.js)

Context API: Introduction and Building Blocks

React documentation explains context API as- Context provides a way to pass data through the component tree without having to pass props down manually at every level.

In a typical React application, data is passed top-down (parent to child) via props, but such usage can be cumbersome for certain types of props (e.g. locale preference, UI theme) that are required by many components within an application. Context provides a way to share values like these between components without having to explicitly pass a prop through every level of the tree.

If you can observe the documentation states context for “passing” and “sharing” values and mention nothing about “managing the state”

Use Cases of Context API

The main purpose of using context API is avoiding ‘prop drilling’ – passing prop at every level. It is more like a pipeline used to pass values from one end to another.

Context API provides the easiest way for passing data through the component tree so that you don’t have to pass props down manually at every level. For example, assume we have a component tree consisting of A, B, C, and D components. Now you need to pass props from A to D, so rather than passing it A > B > C > D,i.e., to every component, with the help of context you can directly pass to A > D.

Now, many blogs have mentioned that Context API is the best replacement for Redux because it’s in-built and you don’t have to install dependencies for the same. Is this really true- Can Context API replace Redux? We will discuss this in a further section. Stay tuned to explore!

Building Blocks of Context API

We can divide the Context API into three blocks: 1. Context: Use createContext() function that takes the default value as a first argument. Here it is optional to pass a Javascript object. You can implement multiple contexts in your app.

2. Provider: After creating context, the Provider provides the capability for accessing the context. It provides functions & data to pass values further to the component.

3. Consumer: Consumer allows access to the value to child components which are wrapped by Provider. It has two types-

Context.Consumer: Context.Consumer can be used for both functional and class-based components. However, through this approach, the context is accessible within the render method only.

Static ContextType: Static contextType can be used only for Class-based components.

Redux and Context API Example

The example below is based on a Counter. The initial value will be 0 and it has two buttons to increment and decrement the value.

Inside the main parent counter component, there will be three child components-

one for changing the counter value two for each of the buttons.

The initial setup would be the same for both Context and Redux approaches.

Description

Join a live online community of over 100,000+ developers and a course taught by industry experts that have actually worked both in Silicon Valley and Toronto with React.js. This is a brand new course just released July 2019!

Using the latest version of React: 16.8+, this course is focused on efficiency. Never spend time on confusing, out of date, incomplete tutorials anymore. Graduates of Andrei’s courses are now working at Google, Amazon, Apple, IBM, JP Morgan, Facebook, + other top tech companies.

We guarantee you this is the most comprehensive online resource on React. This project based course will introduce you to all of the modern toolchain of a React developer in 2019. Along the way, we will build a massive e-commerce application similar to Shopify using React, Redux, React Hooks, React Router, GraphQL, Context API, Firebase, Redux-Saga, Stripe + more. This is going to be a full stack app (MERN stack), using Firebase.

The curriculum is going to be very hands on as we walk you from start to finish of releasing a professional React project all the way into production. We will start from the very beginning by teaching you React Basics and then going into advanced topics so you can make good decisions on architecture and tools on any of your future ReactJS projects.

All code is going to be provided step by step and even if you don’t like to code along, you will get access to the the full master project code so anyone signed up for the course will have their own project to put on their portfolio right away.

The topics covered will be:

– React Basics

– React Router

– Redux

– Redux Saga

– Asynchronous Redux

– React Hooks

– Context API

– React Suspense + React Lazy

– Firebase

– Stripe API

– Styled-Components

– GraphQL

– Apollo

– PWAs

– React Performance

– React Design Patterns

– Testing with Jest, Enzyme and Snapshot testing

– React Best Practices

– Persistance + Session Storage

– State Normalization

+ more

Wait wait… I know what you’re thinking. Why aren’t we building 10+ projects? Well, here’s the truth: Most courses teach you React and do just that. They show you how to get started, build 10 projects that are simple and easy to build in a day, and just add some CSS to make them look fancy. In real life though, you’re not building silly applications. When you apply to jobs, nobody is going to care that you built a really pretty To Do app. Employers want to see you build large apps that can scale, that have good architecture, and that can be deployed to production.

Let me tell you 3 reasons why this course is different from any other React tutorial online:

1. You will build the biggest project you will see in any course. This type of project would take you months to implement yourself.

2. This course is taught by 2 instructors that have actually worked for some of the biggest tech firms using React in production. Yihua has been working on some of the biggest e-commerce websites that you have definitely heard of and probably have shopped at. Andrei has worked on enterprise level React applications for large IPOed tech firms in Silicon Valley as well as Toronto. By having both of them teach, you get to see different perspective and learn from 2 senior developers as if you are working at a company together.

3. We learn principles that are important beyond just what you learn as a beginner. Using the instructor’s experiences you learn about design patterns, how to architect your app, organize your code, structure your folders, and how to think about performance. Let’s just say we don’t shy away from the advanced topics.

This course is not about making you just code along without understanding the principles so that when you are done with the course you don’t know what to do other than watch another tutorial. No! This course will push you and challenge you to go from an absolute beginner in React to someone that is in the top 10% of React developers.

Andrei Neagoie is the instructor of the highest rated Development courses on Udemy as well as one of the fastest growing. His graduates have moved on to work for some of the biggest tech companies around the world like Apple, Google, Amazon, JP Morgan, IBM, UNIQLO etc… He has been working as a senior software developer in Silicon Valley and Toronto for many years, and is now taking all that he has learned, to teach programming skills and to help you discover the amazing career opportunities that being a developer allows in life.

Having been a self taught programmer, he understands that there is an overwhelming number of online courses, tutorials and books that are overly verbose and inadequate at teaching proper skills. Most people feel paralyzed and don’t know where to start when learning a complex subject matter, or even worse, most people don’t have $20,000 to spend on a coding bootcamp. Programming skills should be affordable and open to all. An education material should teach real life skills that are current and they should not waste a student’s valuable time.   Having learned important lessons from working for Fortune 500 companies, tech startups, to even founding his own business, he is now dedicating 100% of his time to teaching others valuable software development skills in order to take control of their life and work in an exciting industry with infinite possibilities.

Andrei promises you that there are no other courses out there as comprehensive and as well explained. He believes that in order to learn anything of value, you need to start with the foundation and develop the roots of the tree. Only from there will you be able to learn concepts and specific skills(leaves) that connect to the foundation. Learning becomes exponential when structured in this way.

Taking his experience in educational psychology and coding, Andrei’s courses will take you on an understanding of complex subjects that you never thought would be possible.
