Webpacker to Vite Migration: A Phased Approach

!NOTE: this guide currently only covers the first phase. The Vite setup and migration are not detailed here.

Overview

This guide documents our approach to migrating from Webpacker to a modern frontend asset pipeline. We implemented a phased strategy:

Phase 1 (Current): Replace Webpacker with CDN-based resources
Phase 2 (Future): Migrate to Vite for a modern build system

Rules for LLM Agentic Coding in Docker Containerization Projects

1. Container Architecture Patterns

Follow the Established Pattern: Always respect the established architecture patterns across services (Dockerfile, entrypoint script, management script).
Separate Concerns: Keep build-time operations in Dockerfile, initialization in entrypoint scripts, and user operations in management scripts.
Delegate Appropriately: Entrypoint scripts should handle environment initialization; management scripts should provide a clean interface.
Minimize Verbosity: Management scripts should be concise in output; verbose operations belong in entrypoint scripts.

2. Environment Detection & Configuration

Use Defaults Wisely: Always provide sensible defaults for environment variables.
Check Dependencies: Explicitly check for required dependencies (database, Redis, other services).
Respect Technology Specifics: Recognize and accommodate technology-specific patterns (rake vs rails, Nod

Model Context Protocol (MCP) Servers Configuration Guide

Common Server Setup

All MCP servers follow a basic configuration pattern:

import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

const server = new Server({
