Developer Experience Optimization

This document outlines standards and best practices for optimizing developer experience (DX) across Bayat projects. Following these standards improves developer productivity, satisfaction, and code quality.

Purpose

Developer Experience Optimization aims to:

1. Increase Productivity: Reduce friction in development workflows
2. Improve Satisfaction: Create enjoyable development environments
3. Reduce Onboarding Time: Enable new team members to be productive quickly
4. Enhance Quality: Make it easier to write high-quality code
5. Promote Consistency: Standardize development practices across teams

Development Environment Standardization

Core Development Environment

Standardize development environments across teams:

1. Environment Definition:

   • Define standard development environment components
   • Document setup procedures for all platforms
   • Create automation scripts for environment setup

2. Environment Components:

   • Required tools and versions
   • Editor/IDE configurations
   • Extensions and plugins
   • Runtime environments
   • Local services

3. Environment Management:

   • Containerized development environments
   • Version-controlled configuration
   • Self-service environment provisioning

Environment Setup Automation

Implement automated environment setup:

1. Setup Scripts:

   • Platform-specific setup scripts

   • Dependency management automation

   • Configuration initialization

     #!/bin/bash
     # Example setup script for a Node.js project
     
     # Check prerequisites
     command -v node >/dev/null 2>&1 || { echo "Node.js is required but not installed. Aborting."; exit 1; }
     command -v npm >/dev/null 2>&1 || { echo "npm is required but not installed. Aborting."; exit 1; }
     
     # Install required global tools
     npm install -g typescript eslint prettier
     
     # Install project dependencies
     npm install
     
     # Setup local environment
     cp .env.example .env
     
     # Initialize development database
     npm run db:init
     
     # Verify setup
     npm run verify:environment
     
     echo "Development environment setup complete!"

2. Containerized Environments:

   • Docker Compose configurations

   • Development container definitions

   • Volume mounting standards

     # Example docker-compose.yml for development
     version: '3.8'
     services:
     app:
         build:
         context: .
         dockerfile: Dockerfile.dev
         volumes:
         - .:/app
         - node_modules:/app/node_modules
         ports:
         - "3000:3000"
         environment:
         - NODE_ENV=development
         - DATABASE_URL=postgres://user:password@db:5432/development
         depends_on:
         - db
     
     db:
         image: postgres:13
         volumes:
         - postgres_data:/var/lib/postgresql/data
         environment:
         - POSTGRES_USER=user
         - POSTGRES_PASSWORD=password
         - POSTGRES_DB=development
         ports:
         - "5432:5432"
     
     volumes:
     node_modules:
     postgres_data:
