Laravel Breeze Vue HMR Docker

### 1. Update `vite.config.js`
Ensure your `vite.config.js` file is configured to listen to all network interfaces and includes the correct port for HMR. Add the `server` property as follows:

// vite.config.js
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
  plugins: [vue()],
  server: {
    host: '0.0.0.0',   // Listen on all network interfaces
    hmr: {
      host: 'localhost', // or your custom domain if not localhost
      port: 5173,        // match the port in Docker
    },
  },
});

Replace `localhost` with your Docker host’s IP if not using localhost. The port (`5173` by default) should match the one exposed by Docker.

### 2. Expose Ports in Docker
Ensure that your Docker setup exposes the port Vite is using for HMR (typically `5173`). You can add this to your `docker-compose.yml`:

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "80:80"       # your web server port
      - "5173:5173"   # Vite HMR port

This allows Docker to expose the HMR port so your browser can access it from outside the container.

### 3. Start Vite with Docker
Make sure you’re running Vite in watch mode. You can use an npm command in `package.json`:

"scripts": {
  "dev": "vite --host"
}

### 4. Update Hosts File (if necessary)
If accessing the app from a custom domain, ensure it points to your Docker IP in your hosts file.

### 5. Restart Docker Containers
After making these changes, restart your Docker containers to ensure the configurations take effect:

docker-compose down && docker-compose up -d

These steps should enable HMR in your Docker-based Laravel project with Breeze and Vue. Let me know if it still doesn’t work!

1. **Check Docker’s Network Settings:**
– Run the following command in your terminal to list Docker's network configurations:

docker network inspect bridge

– Look for the `"Gateway"` property in the output. This usually provides the internal Docker network IP for the default bridge network, typically something like `172.17.0.1`.

2. **Using `host.docker.internal`:**
– For Docker on Windows, you can use `host.docker.internal` as an alias to refer to the Docker host IP from within your containers.
– Update your `vite.config.js` to use `host.docker.internal`:

server: {
       host: '0.0.0.0',
       hmr: {
         host: 'host.docker.internal',
         port: 5173,
       },
     }

After this change, restart your Docker containers to apply the new settings. This should help HMR connect correctly between Docker and your Windows 11 setup!

### 1. **Linux / MacOS**
The Docker host IP is typically accessible at `host.docker.internal`. You can test this IP from inside a Docker container:

ping host.docker.internal

If you need the specific IP address on Linux or MacOS, you can use the following command:

ip -4 addr show docker0 | grep -oP '(?<=inets)d+(.d+){3}'

This command will display the IP associated with the `docker0` interface, often `172.17.0.1`, which is Docker’s default bridge network gateway.

### 2. **Windows**
On Windows (with Docker Desktop), `host.docker.internal` is also available. To get the exact IP, run this in a PowerShell terminal:

Get-NetIPAddress -AddressFamily IPv4 -InterfaceAlias "vEthernet (Default Switch)"

### 3. **Cross-Platform (Docker Host IP in Containers)**
If you need an IP that works cross-platform directly within a Docker container, use `host.docker.internal`. Add this to your Docker configuration for `vite.config.js`, or directly in other application configurations.

In your `vite.config.js`, set this IP in the `hmr.host` option as follows:

server: {
  host: '0.0.0.0',
  hmr: {
    host: '172.17.0.1',
    port: 5173, // Ensure this matches the exposed port
  },
},

After updating this, restart your Docker containers to apply the changes. This should allow HMR to connect to the correct IP for your setup.

### 1. Check Console for Errors
First, open your browser’s developer console (F12) and check for any errors in the **Console** or **Network** tab. Look for:

– 404 errors, which could indicate missing files
– CORS errors, which may indicate cross-origin issues

### 2. Verify HMR Connection
Ensure HMR is connected by checking if any WebSocket errors are visible in the console. If you see WebSocket errors, try:

– Reconfirming that `vite.config.js` has the correct settings:

server: {
       host: '0.0.0.0',
       hmr: {
         host: '172.17.0.1', // Docker host IP
         port: 5173,
       },
     },

– Confirm that `5173` is exposed in `docker-compose.yml` as:

ports:
       - "5173:5173"

### 3. Clear Browser Cache
Sometimes, stale cache can cause issues. Clear your browser cache or use an incognito window to ensure you’re not loading old assets.

### 4. Restart Vite and Docker Containers
After making any configuration changes, restart Vite and Docker to apply them:

docker-compose down && docker-compose up -d

### 5. Test Without HMR (Optional)
To confirm that the issue is with HMR, try running Vite without HMR by temporarily removing the `hmr` configuration. This will help identify if the problem is isolated to HMR or something else.

If you still see a blank page or specific errors, let me know the exact errors you’re seeing in the console for more targeted help!

### Suggested Updates and Notes

1. **Ensure `VITE_HOST` is properly set up**
Since you’re running `npm run dev` in the `node` service, ensure Vite is configured to use `0.0.0.0` as the host. Check your `vite.config.js` as well for consistency.

2. **Expose the Vite Port and Configure HMR**
It’s also essential to specify the Docker host IP correctly in `vite.config.js` for HMR. Try using `host.docker.internal` if `172.17.0.1` isn’t working.

### Updated `docker-compose.yml`

    build:
      context: .
      dockerfile: Dockerfile
    container_name: laravel_app

### Updates for `vite.config.js`

In `vite.config.js`, set up the `server` and `hmr` options to listen on `0.0.0.0` and use `host.docker.internal`:

// vite.config.js
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
  plugins: [vue()],
  server: {
    host: '0.0.0.0', // Bind to all interfaces
    hmr: {
      host: 'host.docker.internal', // Alternatively, use '172.17.0.1' if needed
      port: 5173, // Vite HMR port
    },
  },
});

### Steps to Test and Troubleshoot

1. **Restart Docker**
After updating, run:

docker-compose down && docker-compose up -d

2. **Verify Vite is Running in `node` Container**
Check the logs for the `node` container to confirm Vite is serving correctly on `http://0.0.0.0:5173`.

3. **Check Browser Console for HMR Connection**
Open the browser’s console and look for WebSocket or HMR-related errors. If you see any issues, try replacing `host.docker.internal` with `172.17.0.1` or vice versa in `vite.config.js`.

### Updated and Detailed Configuration

#### 1. `vite.config.js` Configuration
To ensure compatibility, let’s set the host and HMR options more precisely. Modify your `vite.config.js` to listen on `0.0.0.0` with specific HMR configurations:

import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
  plugins: [vue()],
  server: {
    host: true,  // Allows external access for Docker
    strictPort: true,
    port: 5173,
    hmr: {
      clientPort: 5173,  // Port for the client to connect to
      host: 'localhost', // You can also try 'host.docker.internal' if on Mac/Windows
    },
  },
});

#### 2. Update Docker Compose for Network Mode and Port Binding

1. Make sure `5173:5173` is exposed correctly on the `node` service in `docker-compose.yml`.
2. Use `network_mode: "host"` for the `node` service to ensure proper networking across host and containers.

Here’s the updated configuration:

version: '3.8'

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: laravel_app
    volumes:
      - ./shareyourthoughts:/var/www/html
    networks:
      - laravel_network
    depends_on:
      - db
    ports:
      - "8080:80"

  db:
    image: mysql:8.0
    container_name: laravel_db
    restart: always
    environment:
      MYSQL_DATABASE: laravel
      MYSQL_USER: laravel
      MYSQL_PASSWORD: password
      MYSQL_ROOT_PASSWORD: rootpassword
    volumes:
      - db_data:/var/lib/mysql
      - ./init-scripts:/docker-entrypoint-initdb.d
    networks:
      - laravel_network

  adminer:
    image: adminer
    container_name: adminer
    restart: always
    ports:
      - "8081:8080"
    networks:
      - laravel_network

  node:
    image: node:latest
    container_name: node
    working_dir: /var/www/html  # Ensure this points to the Laravel project root
    volumes:
      - ./shareyourthoughts:/var/www/html
    command: ["npm", "run", "dev"]  # Run Vite in dev mode
    ports:
      - "5173:5173"
    network_mode: "host"  # Allow networking with host
    environment:
      - VITE_HOST=0.0.0.0

networks:
  laravel_network:
    driver: bridge

volumes:
  db_data:

> **Note:** `network_mode: "host"` may require elevated privileges on certain Docker setups or might be unsupported on Docker Desktop for Mac. In such cases, try with `host.docker.internal` for HMR host in `vite.config.js`.

#### 3. Restart Containers and Clear Cache

1. Restart all services to apply the changes:

docker-compose down && docker-compose up --build -d

2. Clear the browser cache or use an incognito window to prevent loading outdated assets.

#### 4. Debugging Steps

– **Check Vite Output**: Run `docker logs node` to confirm Vite is listening on `0.0.0.0:5173`.
– **Test Connection**: Try accessing `http://localhost:5173` directly in your browser to see if Vite is reachable.
– **Console Logs**: Look for WebSocket or HMR connection errors in the browser console, which might indicate networking issues or port mismatches.
