Go: Building Web Applications

Summary

In this chapter, we learned how five small command-line programs can, when composed together, produce powerful results while remaining modular. We avoided tightly coupling our programs so they are still useful in their own right. For example, we can use our available program just to check if domain names we manually enter are available or not, or we can use our synonyms program just as a command-line thesaurus.

We learned how standard streams could be used to build different flows of these types of programs, and how redirection of the standard input and the standard output lets us play around with different flows very easily.

We learned how simple it is in Go to consume a JSON RESTful APIs web service when we needed to get synonyms from ...
