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

Local development

Install Go.

Clone this repo and switch into it:

$ go get github.com/txcsmad/will-it-rain
$ cd $GOPATH/src/github.com/txcsmad/will-it-rain

Get a Forecast IO API key. Then set the environment variable:

$ export FORECASTIO_API_KEY=<your-api-key>

Run local server.

$ go build
$ ./will-it-rain

Then visit http://localhost:8080
