Introduction to ReactJs
The most important question of this course is What is React and why should we use it. In this lecture, we'll take a closer look.
One of the most important features of ReactJs is JSX which allows us to develop components faster and efficiently. This the objective of this session
Props and States
The core system is ReactJs is driven by two sample thing. Props and States. In this lecture will learn these two things with examples
Though in current time, the Class component is discouraged to use, still we need to know our ancestor to understand our modern development system. So we will get to know the class component in this lecture. Don't Worry, we will learn everything in ReactJs hooks.
In this lecture, we will get to know the Functional Component and the react Hooks which is the modern way of building a react application.
The most important thing in ReactJs is to understand the lifecycle of a component without which the whole ReactJs will be a big black hole. So Let's learn the LIFECYCLE of the ReactJs component. We will demonstrate the both legacy way of lifecycle in-class component and also in the Hooks way, From both of them, we will get to learn why we should use React Hooks instead of Class Component
Life Cycle Hooks
In this Section, We will dig deeper into the basic life cycle hooks of ReactJs. The hooks are useState,useEffect which are use almost every component in a react application
State Manipulation and Two way Data Binding
One of the vital things in a React Application is State Manipulation which we will learn in this lecture as well as will try to implement two-way data binding.
In this section, we will get to know how we can render content depending on our data flow and other factors conditionally
List and Keys
Looping through the contents is one of the most important things we should learn to develop a modern and real life react application. So let's learn this in this section.
Styling React Components
To make an application, it is important to have proper UX and UI. In this section we learn about styling techniques :
- Setting styles dynamically
- Setting Classname dynamically
- CSS Module
More in to Styling
For faster development, we often use various UI libraries. Material UI is one of them and in this section, we will learn about this amazing UI library.
Form and Form Validation
In this section, we learn to create form, handle user input, validating inputs, Handling errors
Debugging and better project structure
In this section, we will learn about two vital things. One is how to debug a React Application using React Developers Tool.
Another topic is how to build a better project structure. Also, we will learn how to clean up react hooks and make them efficient.
We will learn how to communicate with API using the following tools and techniques:
- Difference between GET/POST/PATCH/PUT/DELETE
- Handling errors
- Handling asynchronous API calling
A very important feature of ReactJS is Routing and in this session, we will talk and learn about ReactRouter and some of its features:
- Setting up Router Package
- Components of routers
- Switching between pages
- Using porps via router
- Navlink/Link component of router
- History and Params Hooks
Due to the Unidirectional Data Flow of React, often we have to use a common store, and a very popular library is Redux. In this session we will learn:
- Understanding Redux Flow
- Setting up reducers and store
- Dispatching actions
- Connect React to redux
- Passing data with action to store
- Update store immutably
- Combining multiple reducers
- Connect component with redux hooks
- Setting up redux dev tools
Redux Middle Ware
- Why middleware is important
- Redux Thunk
- Configuring Thunk to store
- Implement store with redux thunk
- A brief overview of redux-saga
There some other hooks in ReactJs and we will have a brief overview of those hooks.
As it's a frontend library, we have to think about updating the performance to ensure a smooth user experience. So we will learn about some performance enhancer and their use.
- React Profiler
- Generate react source-map
Final Project analysis and discussion session
Throughout the whole course, all the topics will be discussed with real-time project implementation and at the end of the day, a final project will be given to everyone. In this session, we will analyze the submission and have a discussion over how to make it more efficient and performance-friendly.
What Students Said
The instructor was really helpful and friendly. I started from scratch. Did not have really good footing over js, or CSS. The instructor helped all of us with also this. The overall Teaching process was really good. Gave us a really good idea of the basics of react
I have been learning ReactJs from Arnab Dhar in this Batch-3 and it has been a great experience. He is a very thoughtful teacher who puts a lot of thought into how he presents the material. His lessons were engaging, useful, and he was very patient with everyone in class always encouraging his students to try. I would highly recommend him to anyone interested in learning (ReactJs).
By doing this course I have learned a lot, including how to create a client application, every topic of ReactJs is explained in a very different way here. The teacher of our course was very friendly.
