Thin wrapper around random-js (https://github.com/ckknight/random-js) to provide reproducibility.
The intended use-case is within test suites which generate random data for fuzzing -- using this library will allow you to run the exact same test suite with the same fuzzed data, which should help with debugging flickering tests.
In Typescript/ES6:
import { random } from 'reproducible-random'
const foo = random.integer(0, 100)
const bar = random.bool()
console.log({
foo,
bar,
})
When run, this will output a line of the form RANDOM_SEED=123456789 on the console, which can then be passed back in as an environment variable for reproducing the same random data.
