Please consider the hints at the end of this document. This task is not about implementing a performant fibonacci algorithm, it is about productive and structured coding.
Write an API action that returns the n-th value of the fibonacci series.
POST /fibonacci.json
Parameter:
n: [integer] n-th value of the fibonacci series
If the paramter is missing the response should have status code 400 with an appropriate error message.
The successful response should be JSON in the following structure:
{
"value": 3,
"result": 5,
"runtime": 67
}value: the value of the parameter nresult: the n-th value of the fibonacci seriesruntime: time in milliseconds it took to compute the result
Save the computation results on each request to the database.
The data that should be stored:
value: value of the paramternresult: the n-th value of the fibonacci seriesruntime: time in milliseconds it took to compute the resultcreated_at: creation datetime of the record
Write an API action that returns the last 10 computation results from the database in JSON format.
GET /fibonacci.json
Parameters: none
The successful response should be JSON in the following structure:
[
{
"value": 3,
"result": 5,
"runtime": 67,
"created_at": "2019-01-30T12:45:56Z"
},
{
"value": 10,
"result": 55,
"runtime": 187,
"created_at": "2019-01-30T12:43:34Z"
}
]The main purpose of these tasks is to see that you know the rails stack and get a glimpse of your coding style.
You can use the docker setup to start the server with:
make server
or
make server-rebuild
if you need to rebuild the docker image.
- tackle each mission one after another
- commit at least after each mission is completed
- use libraries whenever they fit
- write passing specs!
- keep it simple and focus on the task
- don't forget the edge cases
- make sure the endpoints are actually working as expected
