# Project Builder Plan: yellow_calculator_app_20251004_113258

This document outlines the high-level plan for scaffolding the 'yellow_calculator_app_20251004_113258' project using io8 MCP.

## 1. High-Level Scaffolding Plan

### Backend (Spring Boot)
- **Core Application Structure**: Standard Spring Boot application with `src/main/java`, `src/main/resources`, and `src/test/java` directories.
- **RESTful API**: Endpoints for calculator operations (add, subtract, multiply, divide).
- **Database Integration**: MySQL database integration using Spring Data JPA.
- **Business Logic**: Service layer to handle calculator logic.
- **Error Handling**: Global exception handling for API errors.

### Frontend (Angular Clarity)
- **Application Structure**: Standard Angular application with `src/app` for components, services, and modules.
- **Calculator Component**: A main component to display the calculator interface.
- **Input Fields**: Two input fields for numbers and a dropdown/buttons for operations.
- **Display Result**: An area to display the calculation result.
- **Service Integration**: Angular services to interact with the Spring Boot backend API.
- **Clarity UI Components**: Utilize Clarity components for a consistent and accessible UI.

## 2. Directory and File Scaffolding Strategy

The io8 platform has generated the initial project structure. The `git pull` command in Step 3 has populated the project directory with the base code.

- **Backend**:
    - `src/main/java/com/example/calculator/`: Package for Spring Boot application, controllers, services, repositories, and models.
    - `src/main/resources/application.properties`: Configuration for database connection and other Spring Boot settings.
    - `src/test/java/com/example/calculator/`: Unit and integration tests for backend logic.
- **Frontend**:
    - `src/app/`: Main Angular application directory.
    - `src/app/calculator/`: Directory for calculator-specific components, services, and modules.
    - `src/environments/`: Environment-specific configurations.
    - `angular.json`, `package.json`, `tsconfig.json`: Standard Angular configuration files.

## 3. Build Tools and Scripts

The io8 platform handles the initial code generation and build process.

- **Backend**:
    - Maven/Gradle (depending on io8's internal setup for Spring Boot) will be used for building the Java application.
    - `mvn clean install` or `gradle build` will be the typical build commands.
- **Frontend**:
    - Node.js and npm/yarn will be used for building the Angular application.
    - `npm install` or `yarn install` for dependency management.
    - `ng build` for compiling the Angular application.

## 4. Pre-Developer Checks

Before a developer starts working on the project, the following checks should be performed:

- **io8 Project Creation Confirmation**: Verify that `.sureai/io8_mcp/responses/create_project.out` exists and contains valid project details (project ID, backend ID, module ID, Gitea URL).
- **App Build Confirmation**: Verify that `.sureai/io8_mcp/responses/build_app.out` exists and indicates a successful build.
- **Git Pull Confirmation**: Verify that `.sureai/io8_mcp/responses/git_pull_status.out` exists and confirms a successful `git pull`.
- **Wireframe Creation Confirmation**: Verify that `.sureai/io8_mcp/responses/create_wireframe.out` exists and contains the wireframe details.
- **Codebase Availability**: Ensure that the project directory contains the generated backend and frontend code after the `git pull`.
- **Dependency Installation**: For frontend, ensure `node_modules` are present or `npm install` can be run successfully. For backend, ensure Maven/Gradle dependencies are resolved.
- **Basic Application Run**: Attempt to run the generated backend and frontend applications to ensure they start without immediate errors.
