⛔️ DEPRECATED: interface-peer-discovery is now included in libp2p-interfaces
interface-peer-discovery
A test suite and interface you can use to implement a Peer Discovery module for libp2p.
The primary goal of this module is to enable developers to pick and/or swap their Peer Discovery modules as they see fit for their application, without having to go through shims or compatibility issues. This module and test suite was heavily inspired by abstract-blob-store.
Publishing a test suite as a module lets multiple modules all ensure compatibility since they use the same test suite.
The API is presented with both Node.js and Go primitives, however, there is not actual limitations for it to be extended for any other language, pushing forward the cross compatibility and interop through diferent stacks.

Badge
Include this badge in your readme if you make a new module that uses interface-peer-discovery API.
Usage
Node.js
Install interface-discovery
as one of the dependencies of your project and as a test file. Then, using mocha
(for JavaScript) or a test runner with compatible API, do:
const test = require('interface-discovery')
const common = {
setup () {
return YourDiscovery
},
teardown () {
// Clean up any resources created by setup()
}
}
// use all of the test suits
test(common)
API
A valid (read: that follows this abstraction) Peer Discovery module must implement the following API:
start
the service
await discovery.start()
Start the discovery service.
It returns a Promise
stop
the service
await discovery.stop()
Stop the discovery service.
It returns a Promise
discoverying peers
discovery.on('peer', (peerInfo) => {})
Everytime a peer is discovered by a discovery service, it emmits a peer
event with the discover peer's PeerInfo.
