FizzBuzz as a Service (FBaaS)

various implementations of FizzBuzz as a Service.

see the branch list for each implementation.

specification

a 'natural number' is a member of the set of positive integers {1, 2, 3, …}.

response

all successful response bodies are in UTF-8 encoded JSON. all errors are 500s with empty body, or 404s as appropriate.

get FizzBuzz range

GET /fizzbuzz/a,b

error if a > b or if either a or b is not a natural number. if b > 100000, behavior is undefined.

otherwise given the natural number interval [a,b], respond with a string constructed as follows:

for each n in [a,b]:

  1. if n is evenly divisible by 3, append the string "Fizz".
  2. if n is evenly divisible by 5, append the string "Buzz".
  3. if n is evenly divisible by neither 3 nor 5, append n as a string.
  4. append a line-feed character "\n"

example request

GET /fizzbuzz/1,20
