Reduced is a modern free web application that reduces the length of a link URL so it’s easier to remember, share and track. In other words, Reduced is an Open-Source URL Shortener. Convert those ugly and long URLs into short, easy to manage links and QR-Codes. If you want to run a more complex and advanced URL shortener, take a look at my Shlink Installation guide. If you want to run a simple UI URL shortener, take a look at my Lynx Installation guide. In this step by step guide I will show you how to install Reduced on your Synology NAS using Docker and Portainer.

    healthcheck:
      test: ["CMD", "pg_isready", "-q", "-d", "reduced", "-U", "reduceduser"]
      timeout: 45s
      interval: 10s

      - /volume1/docker/reducedb:/var/lib/postgresql/data
    environment:
      POSTGRES_DB: reduced
      POSTGRES_USER: reduceduser
      POSTGRES_PASSWORD: reducedpw
    restart: always

  reduced-back:
    image: ghcr.io/origranot/reduced.to/backend:master
    container_name: Reduced-BACK
    hostname: reduced-back
    security_opt:
      - no-new-privileges:true
    user: 1026:100
    environment:
      - APP_PORT=3000
      - RATE_LIMIT_TTL=60
      - RATE_LIMIT_COUNT=10
      - FRONT_DOMAIN=http://reduced-front:5000
      - DATABASE_URL=postgresql://reduceduser:reducedpw@reduced-db:5432/reduced?schema=public
      - JWT_SECRET=MariushostingMariushostingMari13
    restart: always
    depends_on:
      reduced-db:
        condition: service_started

  reduced-front:
    image: ghcr.io/origranot/reduced.to/frontend:master
    container_name: Reduced-FRONT
    hostname: reduced-front
    security_opt:
      - no-new-privileges:true
    healthcheck:
      test: wget --no-verbose --tries=1 --spider http://localhost:5000/ || exit 1
    user: 1026:100
    environment:
      - API_DOMAIN=http://reduced-back:3000
    ports:
      - 8302:5000
    restart: always
    depends_on:
      - reduced-back
      - reduced-db

Note: Before you paste the code above in the Web editor area below, change the value numbers for user with your own UID and GID values. (Follow my step by step guide on how to do this.) 1026 is my personal UID value and 100 is my personal GID value. You have to type in your own values.
Note: Before you paste the code above in the Web editor area below, change the value for JWT_SECRET and add your own JWT SECRET. MariushostingMariushostingMari13 is an example for a JWT SECRET. You should invent your own Value. Add 32 random characters, both letters and numbers.

• STEP 13

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

• STEP 14

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

• STEP 15

Go back to STEP 1 or you will deal with karma 🙂.

• STEP 16

Now open your browser and type in your HTTPS/SSL certificate like this https://reduced.yourname.synology.me In my case it’s https://reduced.mariushosting.synology.me If everything goes right, you will see the reduced main page. Type in a long link then click SHORTEN URL to shorten your very long URL into an URL with fewer characters. Follow the instructions in the image below.

• STEP 17

You can also switch to the Dark Mode theme. Follow the instructions in the image below.

Enjoy Reduced!
