Main Webserver Issue

Main Webserver Issue: Troubleshooting and Optimization

Setting up a webserver can be a complex task, especially when using containerization tools like Docker. In this article, we will discuss a common issue that arises when using Docker Compose to set up a webserver, specifically with the LibreLingo project. We will explore the root cause of the problem and provide step-by-step solutions to resolve it.

Issue 1: Missing Node Modules Setup

When using Docker Compose to set up a webserver, it is essential to ensure that the node modules are properly installed and configured. However, in some cases, the Docker Compose file may not include the setup of node modules, leading to errors and issues.

Solution: Create Node Modules Folder Manually

To resolve this issue, you need to create the node modules folder manually. You can do this by running the following command:

mkdir -p /opt/LibreLingo/node_modules

This will create the node modules folder and its subdirectories, allowing you to install the required packages.

Issue 2: Missing Vite Config

Another common issue that arises when using Docker Compose is the missing Vite config. Vite is a popular tool for building and serving web applications, and it requires a configuration file to function properly.

Solution: Update Vite Config

To resolve this issue, you need to update the Vite config file to include the allowed hosts. You can do this by navigating to the vite.config.ts file and updating the server.allowedHosts property to include the domain name of your web application.

Here is an example of the updated Vite config file:

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';
import { plugin as mdPlugin, Mode } from 'vite-plugin-markdown';

export default defineConfig({
    css: {
        preprocessorOptions: {
            sass: {
                quietDeps: true,
                silenceDeprecations: ['legacy-js-api'],
                api: 'modern-compiler' // or 'modern'
            },
            scss: {
                api: 'modern-compiler', // or 'modern'
                quietDeps: true,
                silenceDeprecations: ['legacy-js-api', 'import', 'global-builtin']
            }
        }
    },
    plugins: [sveltekit(), mdPlugin({ mode: [Mode.MARKDOWN] })],
    server: {
        fs: {
            allow: [
                // search up for workspace root
                //searchForWorkspaceRoot('.'),
                // your custom rules
                'config'
            ]
        },
        allowedHosts: ['lingo.example.com'] // Change this line
    }
});

Including Steps in Docker Compose File

To ensure a smooth installation, it is essential to include the steps outlined above in the Docker Compose file. Here is an example of how you can include these steps in the Docker Compose file:

version: '3'

services:
  web:
    build: .
    ports:
      - "3000:3000"
    environment:
      - NODE_ENV=development
    volumes:
      - .//web:/opt/LibreLingo/apps/web
      - ./node_modules:/opt/LibreLingo/node_modules
    depends_on:
      - db
    command: npm run start

  db:
    image: postgres
    environment:
      - POSTGRES_USER=librelingo
      - POSTGRES_PASSWORD=librelingo
      - POSTGRES_DB=librelingo
    volumes:
      - ./db:/var/lib/postgresql/data

By including these steps in the Docker Compose file, you can ensure that the node modules are properly installed and configured, and that the Vite config is updated to include the allowed hosts.

In conclusion, setting up a webserver using Docker Compose can be a complex task, but by following the steps outlined above, you can resolve common issues and ensure a smooth installation. Remember to create the node modules folder manually and update the Vite config file to include the allowed hosts. By including these steps in the Docker Compose file, you can ensure that your web application is properly configured and ready for deployment.

In our previous article, we discussed a common issue that arises when using Docker Compose to set up a webserver, specifically with the LibreLingo project. We explored the root cause of the problem and provided step-by-step solutions to resolve it. In this article, we will answer some frequently asked questions (FAQs) related to the main webserver issue.

Q: What is the main webserver issue?

A: The main webserver issue is a common problem that arises when using Docker Compose to set up a webserver. It is characterized by the absence of node modules setup and missing Vite config, leading to errors and issues.

Q: Why is the node modules folder not created automatically?

A: The node modules folder is not created automatically because the Docker Compose file does not include the setup of node modules. This is a common oversight that can lead to errors and issues.

Q: How do I create the node modules folder manually?
