Starting a development project is a crucial phase that determines the success or failure of the entire project. A methodical approach helps avoid common pitfalls and lay solid foundations.

🎯 Process Overview

Key Phases

1. Analysis and Understanding - Define the problem
2. Planning - Structure the solution
3. Architecture - Design the technical structure
4. Setup - Initialize the environment
5. Iterative Development - Build progressively

📋 Phase 1: Analysis and Understanding

Problem Definition

Essential Questions

Need Analysis

What problem are we solving?

• Main problem to solve
• Affected users
• Expected impact

Who are the users?

• User profiles (personas)
• Technical skills
• Usage constraints

What are the constraints?

• Available budget
• Imposed deadlines
• Human resources
• Technical constraints
• Regulations to comply with

Analysis Template

Requirements Document - [Project Name]

1. Context and Objectives

• Secondary user: [Description, needs, constraints]
• Administrators: [Roles, permissions, needs]

3. Features

Essential Features (MVP)

• Feature 1: [Detailed description]
• Feature 2: [Detailed description]

Desired Features

• Enhancement 1: [Description, priority]
• Enhancement 2: [Description, priority]

4. Technical Constraints

• Performance: Expected response time
• Security: Required security level
• Compatibility: Supported browsers, devices
• Scalability: Expected growth

📊 Phase 2: Planning

Breaking Down into User Stories

User Story Template

As a [type of user] I want [desired functionality]
So that [benefit/value obtained]

Acceptance Criteria

• Criterion 1: [Specific condition]
• Criterion 2: [Specific condition]
• Criterion 3: [Specific condition]

Definition of "Done"

• Code developed and tested
• Unit tests passing
• Documentation updated
• Code review completed
• Deployed to test environment

Concrete Example

User Story: User Authentication

As a application user I want to log in with my email and password So that I can access my secure personal space

Acceptance Criteria

• I can enter my email and password
• I receive an error message if credentials are incorrect
• I'm redirected to dashboard after successful login
• My session remains active for 24h
• I can log out at any time

Technical Tasks

• Create login form
• Implement client-side validation
• Develop authentication API
• Manage user sessions
• Add error messages
• Unit and integration tests

MoSCoW Prioritization

Feature Prioritization

Must Have (Mandatory - MVP)

• User authentication
• Account creation
• Main functionality 1
• Main functionality 2

Should Have (Desirable - V1.1)

• Email notifications
• Advanced user profile
• Data export

Could Have (Optional - V1.2+)

• Dark theme
• Third-party integrations
• Advanced analytics

Won't Have (Not for this version)

• Native mobile app
• AI/Machine Learning
• Multi-language support

🛠️ Phase 4: Setup

Environment Configuration

Setup Checklist

# 1. Version control
git init
git remote add origin [repository-url]
echo "node_modules/" > .gitignore
echo ".env" >> .gitignore

# 2. Node.js environment
npm init -y
npm install express cors helmet dotenv
npm install --save-dev nodemon jest eslint prettier

# 3. ESLint configuration
npx eslint --init

# 4. Prettier configuration
echo '{"semi": true, "singleQuote": true}' > .prettierrc

# 5. package.json scripts
# "dev": "nodemon src/server.js"
# "test": "jest"
# "lint": "eslint src/"

#### Environment Variables

```bash
# .env.example
NODE_ENV=development
PORT=3000
DATABASE_URL=postgresql://user:password@localhost:5432/dbname
JWT_SECRET=your-secret-key
REDIS_URL=redis://localhost:6379
EMAIL_SERVICE_API_KEY=your-email-api-key

### Initial Codebase

#### Backend Structure (Express.js)

```javascript
// src/server.js
const express = require('express');
const cors = require('cors');
const helmet = require('helmet');
require('dotenv').config();

const app = express();
const PORT = process.env.PORT || 3000;

// Middleware
app.use(helmet());
app.use(cors());
app.use(express.json());

// Routes
app.use('/api/auth', require('./routes/auth'));
app.use('/api/users', require('./routes/users'));

// Error handling
app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).json({ message: 'Something went wrong!' });
});

app.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`);
});

## 📋 Getting Started Checklist

### Before Coding

- [ ] **Analysis**: Need clearly defined and documented
- [ ] **User Stories**: Features broken down and prioritized
- [ ] **Mockups**: User interface defined
- [ ] **Architecture**: Technical structure validated
- [ ] **Technologies**: Stack chosen and justified
- [ ] **Environment**: Development, test, production configured

### Technical Configuration

- [ ] **Repository**: Git initialized with appropriate .gitignore
- [ ] **Dependencies**: Necessary packages installed
- [ ] **Linting**: ESLint/Prettier configured
- [ ] **Tests**: Test framework in place
- [ ] **CI/CD**: Basic pipeline functional
- [ ] **Documentation**: README and docs structure created

### First Iteration

- [ ] **Hello World**: Basic functional application
- [ ] **Routing**: Main routes defined
- [ ] **Database**: Connection and basic migrations
- [ ] **Authentication**: Auth structure in place
- [ ] **Tests**: First unit tests
- [ ] **Deployment**: First successful deployment

<Note type="success">
**Objective**: At the end of this phase, you should have a basic functional application that you can deploy and iterate on rapidly.
</Note>

## 🚀 Getting Started Best Practices

### Do's

- **Start simple**: MVP first, advanced features later
- **Automate early**: Tests and deployment from the beginning
- **Document**: Important decisions and architecture
- **Validate regularly**: Frequent user feedback
- **Secure**: Authentication and authorization from the start

### Don'ts

- **Over-engineering**: Avoid premature complexity
- **Premature optimization**: Performance after functionality
- **Perfectionism**: Deliver rather than perfect
- **Scope creep**: Resist feature additions
- **Isolation**: Communicate with team and users
