How I Built a Task Manager App with Spring Boot and React?
In this era of information overload, task management is crucial. I have tried numerous to-do applications, but none felt quite right. Thus I undertook the task of designing an intuitive, functional full-stack Task Manager Application, with a Spring Boot backend and a React frontend.
In this blog post, I will walk you through the entire process of creating this application, what goes through the mind of a tech stack employed, and what personal revelations emerged during this experience - without revealing a single code segment.
The Idea
What I thought of was to create a web-based task manager on which users could:
Create new tasks
View all existing tasks
Edit/update tasks
Mark tasks as completed or still pending
Delete their tasks that they'd not need anymore
Nothing fancy, just straightforward functioning task management with quite a modern interface.
The Tech Stack
The following tools have been selected to convert this into a full-stack app:
Backend: best java full stack classes in nagpur with Spring Boot — to develop a RESTful API and business logic.
Frontend: React.js - to adopt SPA development at a fast pace with quick response.
Database: was initially H2 (an in-memory database for fast testing) and shifted later to PostgreSQL to keep the data persistent.
Others & tools: Git control for versioning, Maven and npm to manage dependencies, Docker as an optional containerizing tool.
Project Structure
Two separate directories were set up: one for frontend and one for backend. Separation helped produce, test, and deploy separate parts individually.
The backend directory had the Spring Boot app exposing REST APIs for task operations.
The frontend directory had... The React app that consumed those APIs to show and interact with tasks.
Backend – Building the API
The entire backend work encompassed business rules and definitions regarding data manipulation. I defined endpoints for:
Fetching all tasks for the sake of showing on the frontend.
Creating a new task when the user submits something new.
Updating an old task-to edit the title, description, or marking it as done.
Deleting tasks-to clean up done or irrelevant stuff.
Database Interaction uses Spring Boot with Spring Data JPA. The data model is very simple in nature, with an identifier for each task, its title, a description, and then a boolean flag for whether it is completed.
I used in-browser tools like Postman for quick tests against the backend-a few clicks on Postman before the application integrates with the frontend.
Frontend – Crafting the UI
As soon as the backend was complete and served up data in JSON, the frontend with React was next on the agenda.
It is clean and simple and has the following features: A form for creating and modifying tasks.
A list view to show all tasks.
Action buttons to enable edit, delete, or mark done. Using the lifecycle methods (or hooks) of React concerning state management, I created a responsive interface directly linked to the backend. For HTTP requests made to the Spring Boot API, Axios was used, while React Router handled navigation (this was mainly for a single-page application).
It was easy to have a front-end link to the backend with real great-time interactivity-a seaming user experience.
Connecting Frontend to Backend
In the early phases, I initially had to deal with the notorious CORS error when the frontend running on port 3000 was trying to access the backend on port 8080, and the browser would not allow it. I fixed this problem by enabling CORS support in the backend since it's usually required in any kind of stack development.
After configuring CORS, the frontend and backend were communicating seamlessly. Requests for POST, GET, PUT, and DELETE were sent by the client React app, which the Spring Boot server handled.
Testing the App
With both layers working, I began testing the app rigorously: Adding new tasks worked as expected, and they appeared instantly.
Editing and deleting tasks changes reflected in UI and in the database.
I tried some edge cases, e.g., submitting empty tasks, deleting non-existing ones, and added error handling as required.
In terms of real usage, I created a number of tasks and updated them over time. It was gratifying to see that everything remained responsive and consistent.
Bonus – Containerization with Docker
It now allows me to run the whole application with a single docker-compose command for starting and running the exact environment without the overhead of deployment. It's also going extremely well for my project because I can just put it in the cloud or into a private server without worrying much about environmental differences.

Wrap-up!
Building this task manager app has become an exciting learning experience. It leveled me up on both the frontend and backend parts of development and enhanced my knowledge of how functioning applications are laid out in the real world.
If you're a developer going into full-stack development, I'd suggest embarking on something similar. You start simple, build it brick by brick, and slowly allow its complexity to catch on to you.
Want to Give It a Try Yourself?
If, however, you intended to write one, let me suggest that you begin implementing this:
Spend some time learning the basic concepts of Spring Boot; write a REST API that is rather simple.
And go ahead and grab React and create a front end that can consume that API.
Link up the two, handle CORS, and then start testing your features.
Start gradually pushing more complexity (authentication, database persistence, etc.).
