Hi folx! My name's Kent, and I like computers. This repo is a pretty simple little app that gets the weather for a given city.
- Download and install the go binary for your operating system from here
- Clone the repo into
$GOPATH/src(echo $GOPATHafter installing the binary) - From the project root:
go get ./... - From the project root:
go build export OPENWEATHERMAPAPIKEY=<api-key>. You can get an api key from the openweathermap website for free.get-ze-weather
- I'm a rookie Go developer! In deciding what language to use for this project, I wanted something with the least amount of bootstrapping required, and Go was the perfect fit. All the libraries used in this project are native libraries.
- I'm inexperienced using Go's funky default testing framework. In the course of this project, I learned it from scratch; previously, I've used the Ginkgo and Gomega frameworks. I was considering using them as well, but I felt that they would overcomplicate the tests.
- There are some "idiomatic" things in here that are untested. These are
convertHTTPResponseToByteArrayandpromptUserForInput. I don't like leaving them untested, but I also tried to keep them as small as possible and isolated away from the actual logic. - The only exported function from the
modelspackage has a comment above it. This is a by-product of a go package that I use through Atom that does some aggressive style-checking. Don't interpret it as an endorsement or denouncement of comments. - In general, the code assumes a relatively happy path. My error-handling in Go is not particularly sophisticated, so there's a few hard exits. The code does assume that you're going to input a valid city in a somewhat expected format, e.g.
City,StateorCity Country. - I try to be explicit with variable names, but you might see something glib or silly. I'm sorry that my brain loves the word "response" so much.
- Can I run this on Windows? Please don't. I had to write code on Windows towards the end of this exercise and it was awful.
