Due @ 6:00AM on February 10, 2014 (Submit via Camino)
Now that you’ve created an awesome interactive mock up in the previous assignment, we’re now going to take that mock up and make it into a real, breathing app.
As a result, it’s time to collapse the three HTML pages that you mocked up and make them use real data using jQuery. The goal of this assignment is to retrieve the weather data from forecast.io, that provides a great weather API that you can use for free. You’ll need to get an API key, but it is quite easy. You will get data for your “Current Location”, San Jose, and Sydney. In the next assignment, we will get data from any city.
- Show dynamic weather for “Current Location”, San Jose, and Sydney
- Use the HTML5 location API to get your current location
- Lat/long for San Jose: 37.3382082/-121.88632860000001
- Lat/long for Sydney: -33.8674869/151.20699020000006
- Show the cities in the list and also, in the cities detail pages
- Switch between screens using routing. You should be able to refresh the page and end up in the right place.
- The list is
- Current location is
- San Jose is
- Sydney is
- The list is
- You should be able to switch between Celsius and Fahrenheit. Default to Fahrenheit
- Use jQuery only for this assignment
- Make the weather icons provided as they match values in the API directly
- Use local storage to save the last data that you got from the server immediately. Then call the API to get the latest data.
- Refresh weather data at lest every 10 minutes
- Refresh the time every one minute (without calling the server)
- Use only supplied images for the weather icons (download zip)
Some useful conversions
- Speed or distance. SI units (km) to miles = 0.621371 * km
- Used for things like visibility, wind speed, etc
- Temperature. SI units (Celsius) to Fahrenheit = (celsius * 2) + 30)
- Pressure from HPA (SI unit) to inches = (pressure0.000295299830714100)
- Precipitation in SI (mm) to inches = (precipitation * 0.0393701)
- Wind bearing. See: ttp://stackoverflow.com/questions/3209899/determine-compass-direction-from-one-lat-lon-to-the-other
What to turn in:
- styles.less (if you use LESS for CSS)
- jQuery file (or not if externally linked)
- Image assets
Retrieving Data From Forecast.io
Weather data is retrieved through latitude and longitude combinations, which means that it is very easy to get weather data for any location:
So, let’s say my API key is
a157e0906b1d14fa719de4d1dada05325, and my latitude is
40.7142 and my longitude is
-74.0064 the call would be:
The app can also change between Celsius and Fahrenheit. Do do this, pass in
si for Celsius or
us for Fahrenheit:
API documentation is available at: https://developer.forecast.io/docs/v2 and here is a sample request and response:
It’s quite large, so here it is in a JSON file.
