The JavaScript implementation of the IPFS protocol


ipfs-core is the implementation of the IPFS Core API written in JavaScript without depending on other languages/implementations. It contains all you need to integrate IPFS into your application.

If you want to run IPFS as a standalone daemon process, see the ipfs module.

Getting Started

The ipfs-core package contains all the features of ipfs but in a lighter package without the CLI or HTTP servers:

$ npm install ipfs-core

Then start a node in your app:

import * as IPFS from 'ipfs-core'

const ipfs = await IPFS.create()
const { cid } = await ipfs.add('Hello world')
// QmXXY5ZxbtuYj6DnfApLiGstzPN7fvSyigrRee3hDWPCaf

Next Steps

Browser CDN

You can load IPFS right in your browser by adding the following to your page using the super fast jsdelivr CDN:

<!-- loading the minified version using jsDelivr -->
<script src=""></script>

<!-- loading the human-readable (not minified) version jsDelivr -->
<script src=""></script>

Inserting one of the above lines will make an IpfsCore object available in the global namespace:

async function main () {
const node = await window.IpfsCore.create()
// Ready to use!
// See

Browser bundle

Learn how to bundle IPFS into your application with webpack, parceljs and browserify in the examples.
