Fiona is a tool for creating large sets of pseudo random data. At it's core it uses a Xorshift256 PRNG that makes a mockery of creating predictable seemingly random data.
Documentation
There is more complete, better overview of the features at: fiona.now.sh.
Quickstart
The most basic use case is to generate a random number: fiona().number({ max: 1000000, min: 0 })
// input // output
const myNumber = Fiona(1).number() 313150
const age = Fiona(1).number({ max: 100 }) 31
It becomes more useful when creating data structures.
// input // output
Fiona(2).object({ {
age: seeded => seeded.number({ max: 100 }), "age": 93,
name: seeded => seeded.fullname(), "name": "Mrs Sofia Fraser-Taylor",
iban: seeded => seeded.regex(/[A-Z]{2}\d{2}( \d{4}){4,5} \d{1,3}/), "iban": "KN55 2373 5064 2067 4772 5648 4",
favouriteColor: seeded => seeded.oneOf([ "favouriteColor": "yellow"
'red', }
'yellow',
'blue'
])
})
