Install

In Node.js through npm

$ npm install --save cids

Browser: Browserify, Webpack, other bundlers

The code published to npm that gets loaded on require is in fact an ES5 transpiled version with the right shims added. This means that you can require it and use with your favourite bundler without having to adjust asset management process.

const CID = require('cids')

In the Browser through <script> tag

Loading this module through a script tag will make the Cids obj available in the global namespace.

<script src="https://unpkg.com/cids/dist/index.min.js"></script>
<!-- OR -->
<script src="https://unpkg.com/cids/dist/index.js"></script>

Gotchas

You will need to use Node.js Buffer API compatible, if you are running inside the browser, you can access it by multihash.Buffer or you can install Feross's Buffer.

Usage

const CID = require('cids')

// V1 CID
const cid = new CID(1, 'dag-pb', multihash)

// V0 CID
const cid = new CID(base58Multihash)

API
