@lukeed/csprng 
A tiny (~90B) isomorphic wrapper for
crypto.randomBytesin Node.js and browsers.
Why?
This package allows you/dependents to import a cryptographically secure generator (CSPRNG) without worrying about (aka, checking the runtime environment for) the different crypto implementations. Instead, by extracting a random function into a third-party/external package, one can rely on bundlers and/or module resolution to load the correct implementation for the desired environment.
In other words, one can include the browser-specific implementation when bundling for the browser, completely ignoring the Node.js code – or vice versa.
By default, this module is set up to work with Rollup, webpack, and Node's native ESM and CommonJS path resolutions.
Install
$ npm install --save @lukeed/csprng
Usage
General Usage
1// Rely on bundlers/environment detection 2import { random } from '@lukeed/csprng'; 3 4const array = random(12); 5// browser => Uint8Array(12) [...] 6// Node.js => <Buffer ...>
Specific Environment
1// Choose the "browser" implementation explicitly. 2//=> ! NOTE ! Will break in Node.js environments! 3import { random } from '@lukeed/csprng/browser'; 4 5const array = random(1024); 6//=> Uint8Array(1024) [...] 7 8// --- 9 10// Choose the "node" implementation explicitly. 11//=> ! NOTE ! Will break in browser environments! 12import { random } from '@lukeed/csprng/node'; 13 14const array = random(1024); 15//=> <Buffer ...>
API
random(length)
Returns: Buffer or Uint8Array
Returns a typed array of given length.
