Vue Frontend - Quick Start Guide

✅ Verification Complete

The Vue.js frontend has been verified and actualized. All systems are operational!

Current Status

• Build Status: ✅ PASSED (1.40s)
• Dependencies: ✅ INSTALLED (13 packages)
• Dev Server: ✅ RUNNING (http://localhost:5173)
• Production Build: ✅ TESTED (239.96 kB JS gzipped: 82.81 kB)
• Docker Build: ✅ CONFIGURED (Multi-stage Nginx)

Development Server

Option 1: Using Direct Vite Command (Recommended for Windows)

# Navigate to web directory
cd c:\Sources\GitHub\agent-shaker\web

# Set PATH to include node_modules binaries
$env:PATH = "c:\Sources\GitHub\agent-shaker\web\node_modules\.bin;$env:PATH"

# Start dev server
vite

Server will start at: http://localhost:5173

Option 2: Using npm (if npm works in your environment)

cd c:\Sources\GitHub\agent-shaker\web
npm run dev

Option 3: Using Node directly

cd c:\Sources\GitHub\agent-shaker\web
node node_modules/vite/bin/vite.js

Production Build

cd c:\Sources\GitHub\agent-shaker\web
npm run build

Output: ./dist directory containing optimized production files

Preview Production Build

cd c:\Sources\GitHub\agent-shaker\web
npm run preview

Docker Deployment

Build Docker Image

# From project root
docker build -t mcp-vue-ui -f web/Dockerfile web/

Run with Docker Compose

# From project root
docker-compose up -d

# The Vue app will be served via Nginx on port 80
# Access at: http://localhost

Development Workflow

1. Start Backend Services

# Start PostgreSQL
docker-compose up postgres -d

# Or start the Go server
cd c:\Sources\GitHub\agent-shaker
go run cmd/server/main.go

2. Start Vue Dev Server

cd c:\Sources\GitHub\agent-shaker\web
$env:PATH = "c:\Sources\GitHub\agent-shaker\web\node_modules\.bin;$env:PATH"
vite

3. Access the Application

• Frontend: http://localhost:5173 (Vite dev server)
• Backend API: http://localhost:8080/api (Go server)
• WebSocket: ws://localhost:8080/ws

The Vite dev server will automatically proxy API requests and WebSocket connections to the backend.

Configuration

Vite Proxy (vite.config.js)

server: {
  port: 5173,  // Changed from 3000 to avoid conflict
  proxy: {
    '/api': {
      target: 'http://localhost:8080',
      changeOrigin: true,
    },
    '/ws': {
      target: 'ws://localhost:8080',
      ws: true,
    },
  },
}

Tailwind CSS v4

Modern Tailwind CSS v4.1.18 with:

• Custom color palette
• Custom animations (fade-in, slide-up)
• Responsive utilities

Tech Stack

Troubleshooting

Issue: npm run dev not working

Solution: Use direct vite command:

cd c:\Sources\GitHub\agent-shaker\web
$env:PATH = "c:\Sources\GitHub\agent-shaker\web\node_modules\.bin;$env:PATH"
vite

Issue: Port 3000 already in use

Note: Vite now uses port 5173 by default. If you need a different port:

vite --port 3000

Issue: API calls failing

Check:

1. Go backend is running on port 8080
2. Vite proxy is configured correctly
3. CORS is enabled in Go backend (✅ already configured)

Issue: WebSocket not connecting

Check:

1. Go backend WebSocket hub is running
2. Vite proxy includes WebSocket upgrade headers (✅ configured)
3. Browser console for connection errors
