Meme generator rewritten on Node.js

This repository contains a previous LEMP stack meme generator, rewritten on Node.js along with necessary steps to set up and run the app.

Getting Started

1. Explore docker-compose.yml

Take a look at the docker-compose.yml file to understand the services and configurations defined for Docker or create a Docker external network "meme-generator-net" or create a docker-compose.yml file and copy this configuration:

# ./docker-compose.yml
version: '3'

networks:
  meme-generator-net:
    external: true
    name: "meme-generator-net"

services:
  app:
    image: adhocore/lemp:8.1
    # For different app you can use different names. (eg: )
    container_name: memegenerator
    volumes:
      # app source code
      - ./meme-generator-nodejs:/var/www/html
      # db data persistence
      # Here you can also volume php ini settings
      # - /path/to/zz-overrides:/usr/local/etc/php/conf.d/zz-overrides.ini
    ports:
      - 3000:3000
    environment:
      MYSQL_ROOT_PASSWORD: supersecurepwd
      MYSQL_DATABASE: appdb
      MYSQL_USER: dbusr
      MYSQL_PASSWORD: securepwd
      # for postgres you can pass in similar env as for mysql but with PGSQL_ prefix
    networks:
      - "meme-generator-net"
    restart: always

volumes:
  db_data: {}

2. Run the Docker container

Run the container using Docker Compose:

docker-compose up -d

3. Clone the Repository

Clone this repository to your local machine:

git clone https://repo.gabrielkheisa.xyz/gabrielkheisa/meme-generator-nodejs.git
cd meme-generator-nodejs

4. Bash into the Container

Access the container's terminal/bash, look for it using "docker ps":

docker exec -it <container_name> bash

Update the repository:

apk update

5. Backup SQL table structure

Backup the file table_structure_ronaldo.sql from the repository or via terminal by logging into MySQL

mysql -u root -p

with the password supersecurepwd . Then, select database appdb

use appdb;

and backup the table structure

6. Install Python, video renderer, NPM, and all of the requirements

For video renderer purposes:

apk add --no-cache python3 py3-pip
apk add make automake gcc g++ subversion python3-dev
apk add ffmpeg
pip3 install --upgrade pip
pip3 install mysql-connector-python==8.0.29
pip3 install python-dotenv
apk add npm

7. Install Node.js Development or Production Tools

In this case, for development only, use nodemon, else use pm2:

npm install -g nodemon

8. Configure .env File

Create a .env file in the root directory and add necessary configurations:

DB_HOST=localhost
DB_USER=dbusr
DB_PASSWORD=securepwd
DB_NAME=appdb
PORT=3000

9. Start the Node.js App

Run the application using npm, in a detached session using Linux screen:

apk add screen

Create a screen session for npm:

screen

Install dependencis:

npm install

Run the application using npm:

npm start

Detach from the screen, using CTRL + A then CTRL + D

10. Run the Python video renderer script

Create a screen session for Python video renderer:

screen

Execute the Python video renderer script:

cd videos
python render.py

Detach from the screen, using CTRL + A then CTRL + D

11. Access the Server Endpoint

Navigate to http://localhost:3000 or the configured endpoint in your browser to access the server.

Additional Notes:

• Modify configurations in docker-compose.yml for custom setups.
• Ensure proper permissions and access rights when running docker commands.
