We are pleased to announce to everyone in our community that a new version of our browser extension has been released!

🔦 Highlights

Your node is exposed as window.ipfs on every webpage

The API aims to be compatible with interface-ipfs-core, which means websites can now detect if the property exists in window context and opt-in to use it instead of creating their own js-ipfs node. It saves system resources and battery (on mobile), avoids the overhead of peer discovery/connection, enables shared repository access and more!

Make sure to read our notes on exposing IPFS API as window.ipfs, where we explain it in-depth and provide examples on how to use it your own dapp.

You can also play with simple demo apps that take advantage of window.ipfs:

• IPFS Peer Map provides a visualization of ipfs.swarm.peers
• PeerID-to-QRCode creates QR Codes based on ipfs.id
• and obligatory TODO App, uses ipfs.files for storage

Embedded js-ipfs Node

The Browser Action menu provides a toggle for switching between external IPFS node accessed over HTTP API and embedded, in-memory instance of js-ipfs.

The embedded node is great for quickly sharing files with someone, or for testing a dapp that uses window.ipfs without having to install and start up your own IPFS daemon. Power users can provide own config (eg. to enable experimental pubsub) via Preferences.

Note: The embedded node does not run when external node is selected. Every time you switch back to the embedded node, a new instance is created on-demand. It can take a few seconds for a brand-new node to find peers.

…and more!
