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. 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

2. Explore docker-compose.yml

Take a look at the docker-compose.yml file to understand the services and configurations defined for Docker. Create a Docker external network "meme-generator-net".

# ./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: {}

3. Run the Docker container

Run the container using Docker Compose:

docker-compose up -d

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, and all of the requirements

For video renderer purposes:

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

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

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
