will-it-rain

Find out if it will rain in Austin today! This is part 8 of the spring 2016 web workshops.

What we built

Web app that tells you if it will rain in Austin today. When a user makes a request, the Go server gets the forecast information as JSON, decodes it, and uses the precipitation probability to come up with a "yes" or "no" answer. The answer is rendered to the user using Go's built-in html template package.

Topics

• setting up a web server using the net/http package
• using the html/template package to make simple HTML pages
• error handling
• making HTTP requests, unmarshaling JSON using encoding/json
