Implement a geohashing restful service, as described in XKCD:
Given: GET /geohash?lat=37.421542&lon=-122.085589
Expected Output from API: => 200 application/json {lat: 37.857713, lon: -122.544543}
- Dow Opening Query:
- Accept lat/lon as POST
- Abstract the geohashing logic into a separate module
- Cache the dow opening API call to occur once per day
- Write unit tests for the module and/or TDD your way there!
- Use pipe instead of a callback to handle the stock call
- Implement a "cacheable" function that takes as input a function to cache, and a cacheKey such that when you compose the functions together ie:
cacheable(myFunc() {..}, "my-cache-key")
you are returned a function that caches results for that key; use this function as your caching strategy - Implement a promise-based API
- Make the promise-based API also handle callbacks :)
