Go - shorty

A Golang implementation of URL shortener just like : bitly

Tech stack 💻

Features included 📋

• Rate limiting concept added along with expiry option to maintain service reliability.

• Certain checks to ensure correct URL/domain creation.

• Integrated Redis for scalable and persistent data storage.

• Dockerized the whole application using Docker and Docker-compose

Project Setup 📎

• Clone the repository using git clone <repoURL>

• Go to the project working directory.

• RUN go mod tidy to get all Golang dependencies

• Install docker and docker-compose -> Install (Check docs for help during installation)

• Create a .env file in the main working directory

  • Example .env file:

APP_PORT:(add your port)
DB_ADDR:(add your database port), used Redis mostly locally should be `:6379`
DB_PASS:(add your database password)
DOMAIN:(add your domain where the project will be hosted along with the port)
API_QUOTA:(set to 10 by default, you can choose some other number)

• Run docker-compose up -d to spin docker containers for both Go-fiber and Redis.

• Eventually, you can also set up a makefile to shorthand docker commands

• YOUR Project is up NOW !!

• To test it call API on Postman

• POST request

  • (localhost:3000/api/v1)

{
    "url": "URL_TO_SHORT"
    "short": "CUSTOM_URL_ID"
}

where you will get a response :

{
    "url": "URL_TO_SHORT",
    "short": "SHORTEN_URL",
    "expiry": "SET IT TO A NUMBER say 30",
    "rate_limit": "{how many more number of times API can be called, which in our case will be 9}"
    "rate_limit_reset": "After how much time rate will reset"
}

• GET request
  • (localhost:3000/:SHORTEN_URL) will redirect to the original URL.
