Install

Install with npm

$ npm install randomorg-js --save

or install using yarn

$ yarn add randomorg-js

Or in the browser directly using the unpkg CDN:

<script src="https://unpkg.com/randomorg-js/dist/randomorg.min.js"></script>
<script>
  var randomorg = RandomOrg
  console.log(randomorg)
  console.log(randomorg.generateIntegers)

  // see more below in that README
</script>

Please don't use the https://unpkg.com/randomorg-js shortcut that Unpkg allows you, because it will give you the CommonJS / Nodejs (with module.exports) build, that you can't use in the browser.

Usage

For more use-cases see the tests

All methods from the API documentation - both "Basic Methods" and "Digital Signing" - are exposed as named exports. In addition, it also has request method, which has signature (methodName, params, callback) and one RandomOrg function which has (id) signature and it returns an object with same methods.

ES6

Each method has (id, params, callback) signature, where id is optional.

import {
  generateIntegers,
  generateDecimalFractions,
  generateGaussians,
  generateStrings,
  generateUUIDs,
  generateBlobs,
  getUsage,
  generateSignedIntegers,
  generateSignedDecimalFractions,
  generateSignedGaussians,
  generateSignedStrings,
  generateSignedUUIDs,
  generateSignedBlobs,
  verifySignature,

  // special
  request,
  RandomOrg
} from 'randomorg-js'

CommonJS / Node.JS

Notice that Node > 4 is required for destructing feature.

const {
  generateIntegers,
  generateDecimalFractions,
  generateGaussians,
  generateStrings,
  // ...
  generateSignedBlobs,
  verifySignature,

  // special
  request,
  RandomOrg
} = require('randomorg-js')

So you simply can just use old way

var randomorg = require('randomorg-js')

console.log(randomorg)
console.log(randomorg.generateIntegers)
console.log(randomorg.generateDecimalFractions)
console.log(randomorg.verifySignature)
console.log(randomorg.request)
console.log(randomorg.RandomOrg)
// and etc.

Example

const params = {
  apiKey: 'your api key',
  n: 6,
  min: 1,
  max: 6
}

generateIntegers(params, (err, response) => {
  // there may have `err` or `response.error`
  console.log(err || response.error)

  // response is exactly what the API spec
  // defines as response object
  console.log(response)
  console.log(response.id)
  console.log(response.result)
})

Or using the request method

request('generateSignedStrings', {
  n: 8,
  length: 10,
  characters: 'ab!~cdefg+_-hijk@lmn#$%opqr^stuvwxyz',
}, (err, response) => {
  console.log(err, response)
})

By default the package exports all methods with randomly generated id. To change that, the onoe way can be to add id as first argument to each method e.g. generateStrings(id, params, callback); or the second variant is to call the RandomOrg(id) which returns the same methods and they will use the defined id from the constructor.

const { RandomOrg } = require('randomorg-js')

const random = RandomOrg(123555)

random.generateSignedBlobs({
 apiKey: 'your api key here',
 and: 'other params for that method'
}, (er, { id, result }) => {
  // response always has the same ID what
  // user has provided
  console.log(id) // => 123555
  console.log(result) // => random Signed Blobs
})

// but you still can provide
// different `id` to same method
random.generateSignedBlobs(4444, params, (e, { id }) => {
  console.log(id) // => 4444
})

// or to some other method
random.generateIntegers(2938742, params, (e, { id }) => {
  console.log(id) // => 2938742
})

Contributing

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.
Please read the contributing guidelines for advice on opening issues, pull requests, and coding standards.
If you need some help and can spent some cash, feel free to contact me at CodeMentor.io too.

In short: If you want to contribute to that project, please follow these things

  1. Please DO NOT edit README.md, CHANGELOG.md and .verb.md files. See "Building docs" section.
  2. Ensure anything is okey by installing the dependencies and run the tests. See "Running tests" section.
  3. Always use npm run commit to commit changes instead of git commit, because it is interactive and user-friendly. It uses commitizen behind the scenes, which follows Conventional Changelog idealogy.
  4. Do NOT bump the version in package.json. For that we use npm run release, which is standard-version and follows Conventional Changelog idealogy.

Thanks a lot! :)

Building docs

Documentation and that readme is generated using verb-generate-readme, which is a verb generator, so you need to install both of them and then run verb command like that

$ npm install verbose/verb#dev verb-generate-readme --global && verb

Please don't edit the README directly. Any changes to the readme must be made in .verb.md.

Running tests

Clone repository and run the following in that cloned directory

$ npm install && npm test
