0.21.0-beta.1

This beta release introduces a new, homegrown way of handling RTCPeerConnection instances behind the scenes. Trystero previously used simple-peer which is mostly unmaintained and showing its age. The new peer management code uses modern techniques, makes the build significantly lighter, and allows more flexibility for the project, like getting Trystero working in Node (see the new rtcPolyfill option for details).

If you use Trystero in your projects, please test this new beta version and report any issues you find. If you encounter a problem, be sure to confirm the issue does not occur on the latest stable version (0.20.1) under the same network conditions (e.g. peer A on network 1 <-> peer B on network 2).

Try this release via npm i trystero@beta.

0.20.1

Improvements

• 🐦 Nostr strategy - Default relays are now chosen based on app ID to distribute Trystero connections more evenly
• Updated default relay lists across strategies
• Updated to latest dependency versions

0.20.0

Breaking changes

• 🔐 Auto encrypted sessions - SDPs are now always encrypted by default with a key derived from the app ID and room name. The key can be reverse engineered using these parameters, but it's better than flooding relays with plaintext session descriptions. For extra security, use a custom password argument.

Improvements

• makeAction() now has referential equality when called multiple times with the same name argument. This makes it better suited for reactive frameworks. Thanks to @rogersanick for suggesting it.
• Room leave events should fire reliably in Firefox when a peer closes the window or refreshes. (#77)

0.19.0

Improvements

• Shared peering logic - This release streamlines and consolidates all the different code for interfacing with strategy relays into a single place. This means that peering strategies are now much simpler and it's significantly easier to write new ones (or in future releases, mix and match strategies with the same group of peers). Previously, duplicated logic existed between various strategy modules, but going forward any fixes for deadlocks, race conditions, etc. will benefit all strategies.
• More reliable/faster room entrance/exit events - Joining, leaving, and re-joining rooms should be noticeably faster and more reliable due to the strategy logic overhaul.
• Better support for SSR frameworks - While it isn't working on Node quite yet (but getting closer), you can now import Trystero in Node without causing problems, which avoids the need for workarounds for shared code in SSR frameworks.
• 🪐 IPFS - The IPFS strategy had been broken but is now working again.

New features

• ⚡️ Supabase strategy - A new connection strategy is now available using Supabase, an open-source BaaS built on Postgres.
• Incorrect password handling - joinRoom() now accepts a third argument, a function that will be called if a user tries to join a room with a password that doesn't match other users (docs).

0.18.0

New features

• 🐦 Nostr strategy - A new connection strategy is now available using Nostr, a decentralized network protocol with many public relays.
• Unified relay API - The BitTorrent, Nostr, and MQTT strategies now take relayUrls and relayRedundancy options, so there is shared terminology across strategies and a smaller configuration API. These strategies also expose a getRelaySockets() function that returns a map of URLs to WebSockets.
• Bug fix: Action sender functions can now send empty strings
• Torrent tracker failures are now logged with their URLs

Breaking changes

• 🌊 BitTorrent strategy
  • trackerUrls has been renamed relayUrls
  • trackerRedundancy has been renamed relayRedundancy
  • getTrackers() has been renamed getRelaySockets()
• 📡 MQTT strategy
  • brokerUrls has been renamed relayUrls
  • brokerRedundancy has been renamed relayRedundancy

0.17.0

New features

• 📡 MQTT strategy - A new connection strategy is now available using MQTT, an open protocol for IoT device communication. Thanks to @freehuntx for suggesting the approach.

0.16.0

• (🪐 IPFS) swarmAddresses in IPFS config has been replaced by libp2pConfig

0.15.2

• (🪐 IPFS) Overhauled IPFS strategy
• (🔥 Firebase) Updated to firebase@^10.6.0

0.15.1

• (🔥 Firebase only) fixed getOccupants()

0.15.0

• joinRoom() and makeAction() are now idempotent when called with the same namespaces which allows you to use them as React hooks. See the readme for details. Thanks to @rogersanick for proposing a solution.
