Project Setup ⚙

• Clone the repository using git clone <repo_url>

• Go to the project directory using cd golang-url-shortener

• Run go mod tidy or you can manually install all the golang dependencies using go get <dep_name> command.

• Install docker and docker-compose on windows, follow these instructions for easy setup.

• Create a .env file in /api/ folder similar to .env.example file.

• Run docker-compose up -d to spin the docker containers for Go-Fiber server and Redis database at ports localhost:3000 and localhost:6379 respectively.

• You can test the API using postman or VSCode's thunder client using following api call:

  • POST request at localhost:3000/api/v1 with body:

  {
    "url" : "URL_TO_BE_SHORTEN",
    "custom" : "UNIQUE_CUSTOM_URL_ID"
  }

  which will respond you with a response format:

  {
     "url":                "URL_TO_BE_SHORTEN",
     "short":              "SHORTEN_URL",
     "expiry":             "Cache expiry {set to 30 mins}",
     "rate_limit":         "No of times the API have been called", 
     "rate_limit_reset":   "After how much time the rate limit will reset (in hours)",
  }

  • GET request at localhost:3000/:URL_TO_BE_SHORTEN will redirect to the original URL.
