Understanding Global State Management using Context API and Reducer

Business Scenario

To understand how global theme management works in React, let’s look at a conversation between a manager and an employee.

Manager: 

How can we add a theme feature across the application?

Employee: 

Instead of passing props through multiple components, we can use Context API for global state management.

Manager: How will we handle theme changes?

Employee: 

We can use useReducer to manage theme state and transitions efficiently.

Manager: 

How will users switch themes?

Employee: 

We can add a toggle button in the Navbar to switch between light and dark themes

Manager: What is the benefit of this approach?

Employee: It avoids prop drilling, centralizes state management, and makes the application scalable and maintainable.

Task 1: Understanding BRD

Before you start building anything, you need to clearly understand what the client actually wants.So, let’s begin by understanding the BRD (Business Requirement Document) shared by the client.

BRD Full Form is Business Requirement Details.BRD like a plan for building a house. This plan helps the builder understand what to build.In the same way,BRD tells developers what the client wants to build

Activity

After going through BRD list down the Core Features and  Web Pages in the tabulated Format as shown Below.

Col 1Col 2Col 3
Row 1
Row 2
Row 3

Formula

Profit = Revenue - Cost

Task 2: Create WireFrame

Now that you understand the requirements, don’t jump into coding yet. Before development, we always visualize the layout.

Now lets  create a simple wireframe for the homepage.

A wireframe is like a layout plan of a house. Before building, you decide where rooms, doors, and windows will be placed.Similarly, a wireframe helps you plan where elements like headers, images, and buttons will appear on a webpage—before adding design or colours.

Task 3: Code Editor Installation

Good work on completing the planning phase.

Now we will start development. Before that, make sure your system is ready with the required tools.

In this step we will install the VS code editor that will help to Write code efficiently,Organize files , Run and test your application

Go to the visual studio code official website
