Release Highlights ✨

IPFS API exposed as window.ipfs

IPFS Companion is exposing a subset of IPFS APIs as window.ipfs on every webpage ✨

This means websites can detect that window.ipfs already exists and use it instead of spawning own js-ipfs node, which saves resources, battery etc.

Make sure to read our notes on window.ipfs in v2.2.0.
Additional background and open questions can be found in original issue: Expose IPFS API as window.ipfs (#330)

Some highlights below:

• window.ipfs property in every web page! 🎠
  • also adds window.Buffer if not there
  • also adds window.Ipfs
• Proxies to running js-ipfs or go-ipfs node (via js-ipfs-api) in the extension
  (improves performance and battery life)
  • in-depth 20min talk: How window.ipfs works in IPFS companion
• Scope-based permissions (origin+path)
  • 4min video explanation: window.ipfs scope based permissions
  • ipfs.files.* APIs are additionally sandboxed within an application path (#431, FAQ)
• Built-in access controls for proxied IPFS functions (#382)
  • Non-whitelisted ipfs functions prompt user for a allow/deny 🎭 decision on first use:
    
  • Option on the Preferences to globally enable/disable 🎭 access via window.ipfs proxy:
    
  • Page for managing permissions:
    

• Documentation: window.ipfs.md @ v2.2.0
• Demo apps that use window.ipfs
  • ipfs-peer-map-example
  • ipfs-id-qr-codes

Embedded Node (js-ipfs)

We now provide a mechanism for switching between embedded and external IPFS nodes.

Embedded node is a fine fallback for situations when user needs to quickly share a file with someone or just wants to run a dapp against window.ipfs but has no third party IPFS daemon running locally.
User can provide own config (eg. to enable experimental pubsub) via Preferences (#395, visible only when embedded node type is selected)

UX Note: Embedded node does not run when external one is used. Every time you switch to Embedded node, a new instance is spawned on-demand, so it takes a few seconds for a brand new node to find peers:

Other Improvements

Protocol Indicator in Firefox

This feature is limited to Firefox – sorry Chrome users! :-)

Different color and tooltip are shown when resource was loaded via local gateway:

• grey icon – valid IPFS resource, but loaded from a public gateway (via HTTP)
• aqua icon – IPFS resource loaded via user's custom gateway (actual IPFS was used)

Demo (click to zoom):

Page Actions in Firefox

To make things more intuitive, page-specific actions are available in a short menu under Protocol Indicator:

Support for simplified redirect-based protocol handlers without web+ prefix in Firefox >= 59

Still just a redirect and not a real protocol handler, but it is a step in the right direction.

More info: #164 (comment)

Known Issues

• Support for simplified redirect-based protocol handlers does not work on Android due to upstream bug.

Want help?

• Should we merge virtual roots for the same IPFS Paths on different gateways?
  See pros and cons in #330 (comment)
• Translate user interface to your preferred language! #300
