Building an Enterprise Kanban Board with React, TypeScript, Fluent UI, and Vite

Introduction

As React applications evolve from simple forms and dashboards into enterprise-grade systems, one UI pattern becomes almost unavoidable: the Kanban Board.

Kanban boards are widely used in Agile, Scrum, DevOps, Project Management, Product Development, IT Operations, and Enterprise Workflow Management systems.

Popular platforms such as Microsoft Planner, Jira, Azure DevOps, Trello, and many internal corporate applications rely on the Kanban model to visualize work progress.

In App 85 — Kanban Board, we build a complete enterprise-style board using:

React
TypeScript
Fluent UI
Vite

The objective is not only to display tasks but also to understand how React can transform structured data into a complex visual workflow while maintaining clean architecture and component separation.

This application belongs to Block 5 — Complete Applications of the ReactLab roadmap and consolidates concepts learned throughout the previous eighty-four applications.

What is Kanban?

Kanban is a workflow visualization methodology.

Instead of looking at tasks as a simple list, work is organized into stages.

A common workflow is:

Backlog → To Do → In Progress → Review → Done

Each task moves through the workflow until completion.

This approach provides several benefits:

Visual progress tracking
Bottleneck identification
Team collaboration
Work prioritization
Status transparency
Agile project management

The visual nature of Kanban makes it one of the most effective productivity systems used in modern software development.

React Mental Model

One of the most important lessons of this application is understanding that the Kanban board is entirely derived from data.

We do not manually create columns.

We do not manually place tasks into containers.

Instead:

			
Task Data
↓
Filtering Logic
↓
React Rendering
↓
Kanban Columns
↓
Task Cards

		

The UI is a direct reflection of the application state.

This follows the official React philosophy:

UI is a function of state.

Project Architecture

The project follows a layered architecture:

			
App
│
└── KanbanBoard
      │
      ├── KanbanColumn
      │     │
      │     └── TaskCard
      │
      ├── KanbanColumn
      │     └── TaskCard
      │
      └── KanbanColumn
            └── TaskCard

		

Each component has a single responsibility.

This is one of the most important React design principles.

Why TypeScript Matters

The application uses a strongly typed model:

			
export interface KanbanTask {
  id: number;
  title: string;
  description: string;
  owner: string;
  priority: "Low" | "Medium" | "High";
  status: TaskStatus;
}

		

This provides:

Type safety
Better IntelliSense
Easier refactoring
Clear contracts between components
Reduced runtime bugs

Without TypeScript, large enterprise applications quickly become difficult to maintain.

The Importance of Data Modeling

The entire Kanban board is driven by a collection of tasks.

Each task contains:

Identifier
Title
Description
Owner
Priority
Status

The status field is particularly important because it determines where the task appears.

For example:

status: "In Progress"

automatically places the task in the In Progress column.

No additional UI code is required.

React simply renders the correct output from the data.

Rendering Columns

The board creates columns using filtering logic:

			
tasks.filter(
  task => task.status === "Done"
)

This produces a new collection containing only completed tasks.

The same pattern is repeated for every workflow stage.

This demonstrates one of React’s strongest features:

Declarative Rendering.

Instead of saying:

Move this card to that column.

we say:

Show all tasks whose status is Done.

React handles the rest.

Why Array.filter() Is So Important

The filter function is the heart of the Kanban architecture.

Without filter:

All tasks would appear everywhere.

With filter:

			
Backlog tasks appear only in Backlog
To Do tasks appear only in To Do
Done tasks appear only in Done

This creates a clean separation of workflow stages.

Component Composition

The board demonstrates deep component composition.

The hierarchy is:

			
App
  └── KanbanBoard
        └── KanbanColumn
              └── TaskCard

This allows:

Reusability
Scalability
Maintainability
Testability

Instead of creating one huge file, the application is divided into logical pieces.

This is exactly how enterprise React applications are structured.

Fluent UI Integration

The visual layer is built with Fluent UI.

Fluent UI provides:

Microsoft design language
Accessibility support
Consistent spacing
Enterprise styling
Responsive behavior

The primary components used are:

Card
Badge
Title
Text

Without Fluent UI, much more CSS would be required.

Understanding TaskCard

TaskCard is responsible for displaying a single task.

Its responsibilities include:

Display title
Display description
Display owner
Display priority

Nothing else.

This is important because React components should be focused.

A component should have one responsibility whenever possible.

Understanding KanbanColumn

KanbanColumn receives:

			
title
tasks

and renders:

			
Column Header
Task Card
Task Card
Task Card

The component does not know where tasks come from.

It only knows how to display them.

This separation makes the application easier to maintain.

Why the Board Uses Horizontal Layout

Kanban systems are naturally horizontal.

The board uses:

display: flex;

because workflow progresses from left to right.

This produces:

Backlog | To Do | In Progress | Review | Done

which is the industry standard layout.

Enterprise Applications That Use This Pattern

The architecture used in this application appears in:

Microsoft Planner
Azure DevOps Boards
Jira
Trello
Monday.com
Asana
ServiceNow
CRM systems
ERP systems

Understanding this architecture is valuable because the same concepts appear repeatedly in enterprise development.

Why There Is No useEffect

A common beginner mistake is adding useEffect everywhere.

This application intentionally avoids useEffect.

Why?

Because:

No API requests
No timers
No subscriptions
No external synchronization

The board is entirely generated from local data.

According to React Learn:

Effects should synchronize with external systems.

Since there is no external system here, useEffect is unnecessary.

This is an important React lesson.

Why There Is No State Yet

The board is currently static.

Tasks do not move between columns.

This is intentional.

The purpose is to master rendering architecture before introducing interactions.

Future versions may add:

Drag and Drop
State Management
Reducers
Context API
Persistence
API Integration

The current application focuses on visual workflow architecture.

Preparing for Future Enterprise Apps

This app prepares the foundation for:

App 86 Enterprise Task Manager
App 87 User Management
App 88 Administrative Portal
App 89 Ticket System
App 90 Power BI Dashboard

All of those systems rely on similar architectural principles:

			
Data
↓
Filtering
↓
Components
↓
Rendering
↓
Enterprise UI

		

Mastering Kanban architecture now makes those applications much easier to understand.

Final Thought

The most important lesson from App 85 is that React applications should be driven by data.

The board does not manually manage the UI.
