Five simple programs

In this chapter, we will build five small programs that we will combine together at the end. The key features of the programs are as follows:

  • Sprinkle: This program will add some web-friendly sprinkle words to increase the chances of finding available domain names
  • Domainify: This program will ensure words are acceptable for a domain name by removing unacceptable characters and replacing spaces with hyphens and adding an appropriate top-level domain (such as .com and .net) to the end
  • Coolify: This program will make a boring old normal word into Web 2.0 by fiddling around with vowels
  • Synonyms: This program will use a third-party API to find synonyms
  • Available: This program will check to see whether the domain is available or not using an appropriate WHOIS server

Five programs might seem like a lot for one chapter, but don't forget how small entire programs can be in Go.
