    Getting Started with Create React App

    This project was bootstrapped with Create React App.

    Available Scripts

    In the project directory, you can run:

    npm start

    Runs the app in the development mode.
    Open http://localhost:3000 to view it in your browser.

    The page will reload when you make changes.
    You may also see any lint errors in the console.

    npm test

    Launches the test runner in the interactive watch mode.
    See the section about running tests for more information.

    npm run build

    Builds the app for production to the build folder.
    It correctly bundles React in production mode and optimizes the build for the best performance.

    The build is minified and the filenames include the hashes.
    Your app is ready to be deployed!

    See the section about deployment for more information.

    npm run eject

    Note: this is a one-way operation. Once you eject, you can’t go back!

    If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

    Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

    You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

    Learn More

    You can learn more in the Create React App documentation.

    To learn React, check out the React documentation.

  • SCALABLE-E-COMMERCE IN SPRING

    SCALABLE-E-COMMERCE IN SPRING

    This project was proposed by Roadmap.sh: https://roadmap.sh/projects/scalable-ecommerce-platform

    This backend was developed using Spring Framework, with JWT and Spring Security for security. PayPal was integrated for payments, Twilio for SMS, and Java Mail Sender for emails. Thymeleaf was used to visualize the payment process.

    DEPLOYMENT

    docker compose up --build

    image

    To proceed with the deployment, we need three items: PayPal credentials, Twilio credentials, and Gmail credentials.
