Build Monorepo

For multi-language monorepo with Next.js frontends, AI agents, and blockchain services, Nx is the superior choice over Turborepo.

Evaluation

Nx's polyglot capabilities and enterprise-grade tooling make it the only viable choice for Dreamineering's ambitious multi-stack monorepo. Start with the TypeScript workspace preset and incrementally add Python/Rust support via plugins.

• Multi-language support (TS, Python, Rust, Move, Solidity)
  • Plugin system supports custom language integrations via @nx/plugin
  • Native TypeScript project references for IDE performance
  • Experimental Rust support via @nx/rust plugin
• Blockchain integration (SVM, Move, EVM)
  • Flexible build configurations for non-JS toolchains (e.g., Foundry, Move CLI)
  • Dependency graph prevents invalid cross-stack builds
• AI agent development (Python/TS/Rust)
  • Parallel task execution with Python via @nx/python plugin
  • Shared dependency tracking across languages
• Continuous experimentation
  • Distributed caching with Nx Cloud for rapid iteration
  • Fine-grained test splitting for AI/blockchain services

Architecture Advantages

NX architectural advantages:

1. Unified Dependency Graph
2. Language-Specific Optimization
3. AI Agent CI Pipeline

Unified Dependency Graph

Nx automatically tracks dependencies between Next.js apps, AI agents (Python), and blockchain services (Rust/Solidity), preventing invalid builds when code changes .

Language-Specific Optimization

Example pipeline for a Move-based blockchain service:

// apps/blockchain-move/project.json
{
  "targets": {
    "build": {
      "executor": "@nx/workspace:run-commands",
      "options": {
        "command": "aptos move compile",
        "cwd": "apps/blockchain-move"
      }
    },
    "test": {
      "dependsOn": ["^build"],
      "executor": "@nx/workspace:run-commands",
      "options": {
        "command": "aptos move test",
        "cwd": "apps/blockchain-move"
      }
    }
  }
}

AI Agent CI Pipeline

Nx Cloud enables:

nx affected:test --all --parallel=5 # Split AI agent tests across CI nodes
nx run-many --target=serve --projects=agent-* # Hot-reload multiple agents

Turborepo Limitations

1. Language Ecosystem Gaps
   • No first-class Python/Rust support (requires manual task configuration)
   • Blockchain toolchains like Move require complex turbo.json scripting
2. Scalability Concerns
   • No built-in module boundary rules for mixed JS/non-JS projects
   • Limited IDE integration for cross-language refactoring

Implementation Roadmap

1. Initialize Workspace

   npx create-nx-workspace@latest dreamineering --preset=ts --workspaces
   nx add @nx/react # Next.js support
   nx add @nx/python # AI agents

2. Configure Blockchain Services

   nx g @nx/plugin:plugin @dreamineering/blockchain --importPath=@dreamineering/blockchain

3. Enable Distributed Execution

   nx connect-to-nx-cloud # Enable CI task distribution
