Developer Experience Improvement - Implementation Summary

Issue: #43 - Build developer experience improvement Assignee: @KevinMB0220 Due Date: January 31, 2026 Status: Completed

Acceptance Criteria Met

✅ 1. Environment Validation Script

Created: scripts/validate-env.sh

Enhanced environment validation with:

  • Version checks for Rust, Cargo, Rustup (minimum versions)
  • WASM target verification (wasm32-unknown-unknown)
  • Stellar/Soroban CLI detection
  • System resource checks (disk space)
  • Optional tools validation (Docker, Git)
  • Environment file verification (.env)
  • Color-coded output with clear error messages
  • Comprehensive exit codes and warnings

Usage:

./scripts/validate-env.sh

✅ 2. Automated Dependency Installation with Version Locking

Created: scripts/install-deps.sh

Features:

  • Interactive installation wizard
  • OS detection (macOS/Linux)
  • Automated Rust installation via rustup
  • WASM target installation
  • Stellar CLI installation via cargo
  • Rust toolchain updates (rustfmt, clippy)
  • Docker installation instructions
  • Idempotent (safe to run multiple times)

Version Locking Mechanism:

  • Cargo.lock - Locks all Rust dependencies
  • rust-toolchain.toml - Specifies exact Rust toolchain version
  • Cargo.toml workspace dependencies - Centralized version management

Usage:

./scripts/install-deps.sh

✅ 3. Development Environment Containerization

Docker Setup:

  1. Dockerfile - Multi-stage build:

    • base: Rust toolchain + Stellar CLI
    • development: Full dev environment with tools
    • builder: Production WASM builder
    • artifacts: Minimal image with built WASM

  2. docker-compose.yml - Service orchestration:

    • dev: Interactive development container
    • builder: WASM build service
    • test: Test runner service
    • lint: Linter/formatter service

  3. .dockerignore - Optimized build context:

    • Excludes target/, .git/, .env, IDE files
    • Reduces Docker build time and image size

Usage:

# Start dev environment
docker-compose up dev
docker-compose exec dev bash

# Run services
docker-compose run --rm builder  # Build WASM
docker-compose run --rm test     # Run tests
docker-compose run --rm lint     # Lint code

✅ 4. Quick-Start Scripts for Common Development Workflows

Created Scripts:

  1. scripts/build.sh - Build contracts

    • Supports debug/release modes
    • Per-contract builds
    • Verbose output option
    • Shows output file locations

  2. scripts/test.sh - Run unit tests

    • Per-contract testing
    • Verbose output
    • Show println! output (--nocapture)

  3. scripts/lint.sh - Format and lint code

    • Auto-format with cargo fmt
    • Clippy linting
    • Auto-fix mode
    • Check-only mode (for CI)

  4. scripts/clean.sh - Clean build artifacts

    • Standard clean (target dir)
    • Deep clean (includes cargo cache)
    • Shows disk space saved

  5. scripts/dev.sh - Complete development cycle

    • Runs: validate → build → test → lint
    • Skip individual stages
    • Release mode support
    • Watch mode (with cargo-watch)
    • Comprehensive summary output

All scripts include:

  • --help flag with usage examples
  • Color-coded output
  • Error handling
  • Clear success/failure messages

Additional Deliverables

Documentation

  1. README.md - Updated with new section:

    • "Developer Experience Toolkit" section
    • Updated "Development Workflow" with script examples
    • Enhanced "Troubleshooting" section
    • Docker usage instructions

  2. DEVELOPER_EXPERIENCE.md - Comprehensive guide:

    • Detailed documentation of all tools
    • Usage examples for every script
    • Best practices for different workflows
    • CI/CD integration examples
    • Troubleshooting guide

  3. IMPLEMENTATION_SUMMARY.md (this file):

    • Summary of all changes
    • Quick reference guide
