The Hands-On Scala.js tutorial is really good. But the weatherapp could be changed as follows (if you like):
[1] Mention that it's worth adding the line:
import scalajs.js
(Maybe this need is due to some amateur mistake [e.g. omitting extends in class defn?] by the unskilled issue-raiser himself, but anyway that import solved the rash of syntax errors around js.JSON.parse , js.Array , etc)
[2] IDE was complaining that .runNow is deprecated and should be replaced by .queue - i.e. change:
import scala.scalajs.concurrent.JSExecutionContext.Implicits.runNow to
import scala.scalajs.concurrent.JSExecutionContext.Implicits.queue
[3] Though it's no big deal getting an API key from openweathermap.org (takes 2 minutes max to register), you could change the code in two places...
[3a] replace ".com" with ".org" in:
p(
"Enter the name of a city to pull the ",
"latest weather data from api.openweathermap.com!"
),
[3b] change the URL querybuilding to sth like:
def fetchWeather(query: String) = {
val searchUrl =
"http://api.openweathermap.org/data/" +
"2.5/find?type=like&mode=json&q=" +
query + "&APPID=" + "6ce0e1********************748ec3" //<- replace with your actual API-key
(the idea being that the //-comment encourages the padawans to make the relevant string-substitution)
