Small app making short urls.

1. Clone the repository

2. go build

3. Set the environment variables:

   • SHORTURL_POSTGRES_USER (f.e admin)
   • SHORTURL_POSTGRES_PASSWORD (f.e admin)
   • SHORTURL_SERVER_ADDRESS (f.e localhost:8000)

   For HTTPS support:

   • SHORTURL_HTTPS_ADDRESS (f.e localhost:8080)
   • SHORTURL_CERTFILE (public key, path to the .crt/.pem file)
   • SHORTURL_KEYFILE (private key, path to the .key file)

4. ./shorturl

1. Create short link

   Item	Value	required?
   URL	shorturl.space/api/new	yes
   Request type	POST	yes
   Request body(JSON)	{urlOriginal: $url}, where $url is the URL to be shortened.	yes
