deepId

One function one file deepId() returns 20 bytes of good entropy base64 encoded. Browser and node.

Node

npm run test

which runs:

import deepId from "./deepId.js";
console.log("deepId()", deepId());

If all goes well, you should see output like deepId() wqLDkcKGwqXDjkROWcKrJx1gwpnDjcKJSARzw5rDiw==.

If all does NOT go well, perhaps you are using an old version of node? This project uses the "type=module" setting in package.json and is expected to use import not require(). This requires a relatively new node.

Browser

npx http-server then open test.html in a browser (probably http://localhost:8080/test.html)

which runs:

    import deepId from './deepId.browser.js';
    console.log("deepId()", deepId());

If all goes well, you should see output like deepId() wqLDkcKGwqXDjkROWcKrJx1gwpnDjcKJSARzw5rDiw== in the browser developer tools console. In terms of actually using this script in the browser, first install the dependency npm install @javajosh/deepid Then your html file can load node_modules/javajosh/deepid/deepid.browser.js as a browser module.

Publish

npm run publish

published at npm.org @javajosh/deepid such that anyone in the world can do an npm install @javajosh/deepid!

History

I wrote this codepen in response to this excellent blog post on using better UUIDs. I realized this would make a decent npm package, so I extracted it into a module and published it.
