During Libp2p startup, transport listeners will be created for the configured listen multiaddrs. Some transports support custom listener options and you can set them using the `listenerOptions` in the transport configuration. For example, [libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star) transport listener supports the configuration of its underlying [simple-peer](https://github.com/feross/simple-peer) ice server(STUN/TURN) config as follows:
```js
const transportKey = WebRTCStar.prototype[Symbol.toStringTag]
const node = await Libp2p.create({
modules: {
transport: [WebRTCStar],
streamMuxer: [MPLEX],
connEncryption: [NOISE]
},
addresses: {
listen: ['/dns4/your-wrtc-star.pub/tcp/443/wss/p2p-webrtc-star'] // your webrtc dns multiaddr
},
config: {
transport: {
[transportKey]: {
listenerOptions: {
config: {
iceServers: [
{"urls": ["turn:YOUR.TURN.SERVER:3478"], "username": "YOUR.USER", "credential": "YOUR.PASSWORD"},
{"urls": ["stun:YOUR.STUN.SERVER:3478"], "username": "", "credential": ""}]
}
}
}
}
}
})
```
#### Configuring the NAT Manager
Network Address Translation (NAT) is a function performed by your router to enable multiple devices on your local network to share a single IPv4 address. It's done transparently for outgoing connections, ensuring the correct response traffic is routed to your computer, but if you wish to accept incoming connections some configuration is necessary.
The NAT manager can be configured as follows:
```js
const node = await Libp2p.create({
config: {
nat: {
description: 'my-node', // set as the port mapping description on the router, defaults the current libp2p version and your peer id
enabled: true, // defaults to true
gateway: '192.168.1.1', // leave unset to auto-discover
externalIp: '80.1.1.1', // leave unset to auto-discover
ttl: 7200, // TTL for port mappings (min 20 minutes)
keepAlive: true, // Refresh port mapping after TTL expires
pmp: {
enabled: false, // defaults to false
}
}
}
})
```
##### Browser support
Browsers cannot open TCP ports or send the UDP datagrams necessary to configure external port mapping - to accept incoming connections in the browser please use a WebRTC transport.
##### UPnP and NAT-PMP
By default under nodejs libp2p will attempt to use [UPnP](https://en.wikipedia.org/wiki/Universal_Plug_and_Play) to configure your router to allow incoming connections to any TCP transports that have been configured.
[NAT-PMP](http://miniupnp.free.fr/nat-pmp.html) is a feature of some modern routers which performs a similar job to UPnP. NAT-PMP is disabled by default, if enabled libp2p will try to use NAT-PMP and will fall back to UPnP if it fails.
#### Configuring protocol name
Changing the protocol name prefix can isolate default public network (IPFS) for custom purposes.
```js
const node = await Libp2p.create({
config: {
protocolPrefix: 'ipfs' // default
}
})
/*
protocols: [
"/ipfs/id/1.0.0", // identify service protocol (if we have multiplexers)
"/ipfs/id/push/1.0.0", // identify service push protocol (if we have multiplexers)
"/ipfs/ping/1.0.0", // built-in ping protocol
]
*/
```

# Discoverability and Connectivity
While different p2p applications have different needs and requirements, they might also run in different environments and have different hardware capabilities. These characteristics will influence how other peers can be discovered, as well as how connections are established and kept open.
This document contains a set of guidelines to setup libp2p for the most common use cases, in the context of the typical environments where you can run a `js-libp2p` node.

- [Overview](#overview)
[Node](#node)
## Background
### Discovery
Libp2p offers a variety of options to discover other peers on the network. They range from specifying well known peer addresses, to issue queries in a local network or exchanging peer addresses with other previously discovered peers.
To enable peer addresses exchange, peers need to specify their own announce addresses. Accordingly, announce addresses should be reachable from other peers to be valuable.
### Connectivity
A libp2p node cannot keep a unlimited number of connections over time due to hardware and network constraints. As a consequence, a node must keep the most important connections open at any moment. While certain connections will probably be important over longer periods of time, others might only be important for a smaller interval. Accordingly, libp2p needs to keep track of its open connections over time and verify if there are better connections to establish while keeping an healthy number open.
Well known peers are important for bootstrapping and getting to know other peers in the network. However, they will become less important over time since their main purpose is usually to bootstrap the network and not to provide other services. Moreover, as they will be reached by most of the network, they should be disconnected when they do not provide any more clear value to keep the network healthy.
Libp2p is able to automatically identify the importance of some connections over time, but the application layer should also flag important connections manually to improve the node's sensing of the network. For instance, libp2p will protect connections that are used in their listening addresses, in order to be reachable by other nodes, as well as connections with relevant peers for core protocols like gossipsub.
## Browser
Regarding enabling p2p applications, browsers currently have limitations that have impact on how libp2p should be setup.
### Discovery
Taking into account that a web browser does not offer any mDNS-like local discovery method to find peers on the same network and/or on the same web origin, a browser node will need to know other peers' addresses beforehand, so that it can bootstrap its network. These initial nodes should be used as a way to get to know other peers in the network and establish connections with them. Moreover, some of these peers can also advertise the browser peer to other nodes in the network, so that they can connect to it.
### Connectivity
Browser nodes do not have the ability to "listen" for incoming connections, nor a permanent address that can be dialed later for quick resume. However, Libp2p provides a set of possibilities to overcome these limitations. These solutions usually rely on other nodes to listen for connections on its behalf, as well as to advertise its information to other peers.
A browser node should start by establishing a connection with a known machine. As a result of this connection, the browser node will likely be interested to have its addresses announced to other peers in the network. Given that a browser cannot be dialed, the announced addresses of the node will be addresses that rely on this previously connection as the entry point of a dial request. For example, a circuit relay address from a connected peer. Shortly, browser nodes should have auto-relay enabled, so that they can bind to relay nodes that support HOP and become diable via them.
### Routing
DHTs are an essential building block of a p2p system to provide a lookup mechanism similar to a key-value hash table.
As browsers cannot handle large pools of open connections at the same time, as well as establish direct connections to each others, browser nodes cannot participate efficiently in DHTs. Once again, the best way to circumvent this limitation is to rely on more capable nodes in the network to handle DHT queries on their behalf. Browser nodes can rely on delegate nodes or use the DHT in client mode.
### Overview
The base connections to have a fully functional libp2p browser node are:
- nodes that can listen for incoming connections
- Relay nodes, Webrtc-star servers, ...
- nodes that can enable peer discovery and service discovery
- Webrtc-star servers, Rendezvous servers, DHT server Nodes, ...
- closest nodes
- nodes that can enable efficient routing
- DHT server nodes
- nodes from the pubsub topics mesh
- application protocol peers (as needed via `MulticodecTopology`)
While the first three points are important in any context, the last three points depend on the application use case and if the mentioned subsystems are needed.
TODO: Clearly define what libp2p handles and how it is handled
- Libp2p will protect connections used in their listening addresses like connections to a `webrtc-star` server or connections to a node acting as a relay through the `AutoRelay`, as well as nodes used for peer and service discovery
- Libp2p pubsub routers will protect the most important peer connections
- How to control and avoid excess
- Libp2p will protect connections to n DHT servers
- Libp2p will protect the n (configurable) closest peers on the network and refresh them over time, if needed
- Application protocol peers should be protected

In a Node.js context, there are less limitations that need to be considered regarding discoverability and connectivity compared to browser nodes.
The most common issue is when Libp2p nodes are behind NATs. While NAT is usually transparent for outgoing connections, listening for incoming connections might require some configuration. While its usually possible to manually configure routers, not everyone that wants to run a peer-to-peer application or other network service will have the ability to do so. Moreover, libp2p applications should run everywhere, not just in data centers or on machines with stable public IP addresses.
The best approach at the moment to circumvent this limitation is to rely on relay to communicate indirectly via an intermediary peer.
### Overview
The base connections to have a fully functional libp2p browser node are:
- nodes that can listen for incoming connections when behind a NAT
- Relay nodes, ...
- nodes that can enable service discovery
- Rendezvous servers, DHT server Nodes, ...
- closest nodes
- nodes that can enable efficient routing
- DHT server nodes
- nodes from the pubsub topics mesh
- application protocol peers (as needed via `MulticodecTopology`)

# Migrating to libp2p@30
A migration guide for refactoring your application code from libp2p v0.29.x to v0.30.0.
## Table of Contents

- [Development and Testing](#development-and-testing)
- [Module Updates](#module-updates)
## API
### Pubsub
`js-libp2p` nodes prior to this version were emitting to self on publish by default.
This default value was changed on the pubsub router layer in the past, but we kept it overwritten in libp2p to avoid an upstream breaking change.
Now `js-libp2p` does not overwrite the pubsub router options anymore. Upstream projects that want this feature should enable it on their libp2p configuration.
**Before**
```js
const Gossipsub = require('libp2p-gossipsub')
const Libp2p = require('libp2p')
const libp2p = await Libp2p.create({
modules: {
// ... Add required modules according to the Configuration docs
pubsub: Gossipsub
}
})
```
**After**
```js
const Gossipsub = require('libp2p-gossipsub')
const Libp2p = require('libp2p')
const libp2p = await Libp2p.create({
modules: {
// ... Add required modules according to the Configuration docs
pubsub: Gossipsub
},
config: {
pubsub: {
emitSelf: true
}
}
})
```
The [Pubsub interface](https://github.com/libp2p/js-libp2p-interfaces/tree/master/src/pubsub) was updated on its message signing properties, taking into account the Gossipsub spec updates on [libp2p/specs#294](https://github.com/libp2p/specs/pull/294) and [libp2p/specs#299](https://github.com/libp2p/specs/pull/299)
The signing property is now based on a `globalSignaturePolicy` option instead of the previous `signMessages` and `strictSigning` options. The default to strict signing pubsub messages was kept, but if you would like to disable it, the properties should be changed as follows:
**Before**
```js
const Gossipsub = require('libp2p-gossipsub')
const Libp2p = require('libp2p')
const libp2p = await Libp2p.create({
modules: {
// ... Add required modules according to the Configuration docs
pubsub: Gossipsub
},
config: {
pubsub: {
signMessages: false,
strictSigning: false
}
}
})
```
**After**
```js
const Gossipsub = require('libp2p-gossipsub')
const { SignaturePolicy } = require('libp2p-interfaces/src/pubsub/signature-policy')
const Libp2p = require('libp2p')
const libp2p = await Libp2p.create({
modules: {
// ... Add required modules according to the Configuration docs
pubsub: Gossipsub
},
config: {
pubsub: {
globalSignaturePolicy: SignaturePolicy.StrictNoSign
}
}
})
```
### Addresses
Libp2p has supported `noAnnounce` addresses configuration for some time now. However, it did not provide the best developer experience. In this release, we dropped the `noAnnounce` configuration property in favor of an `announceFilter` property function.
**Before**
```js
const Libp2p = require('libp2p')
const libp2p = await Libp2p.create({
addresses: {
listen: ['/ip4/127.0.0.1/tcp/8000/ws'],
noAnnounce: ['/ip4/127.0.0.1/tcp/8000/ws'],
},
// ... additional configuration per the Configuration docs
})
```
**After**
```js
const Libp2p = require('libp2p')
// Libp2p utils has several multiaddr utils you can leverage
const isPrivate = require('libp2p-utils/src/multiaddr/is-private')
const libp2p = await Libp2p.create({
addresses: {
listen: ['/ip4/127.0.0.1/tcp/8000/ws'],
// Filter function: (ma: Array<multiaddr>) => Array<multiaddr>
announceFilter: (multiaddrs) => multiaddrs.filter(m => !isPrivate(m))
},
// ... additional configuration per the Configuration docs
})
```
It is important pointing out another change regarding address advertising. This is not an API breaking change, but it might have influence on your libp2p setup.
Previously, when using the addresses `announce` property, its multiaddrs were concatenated with the `listen` multiaddrs and then they were filtered out by the `noAnnounce` multiaddrs, in order to create the list of multiaddrs to advertise.
In `libp2p@0.30` the logic now operates as follows:
- If `announce` addresses are provided, only they will be announced (no filters are applied)
- If `announce` is not provided, the transport addresses will be filtered (if a filter is provided)
- if the `announceFilter` is provide it will be passed the transport addresses
## Development and Testing
While this is not an API breaking change, there was a behavioral breaking change on the Websockets transport when in a browser environment. This change might create issues on local test setups.
`libp2p-websockets` has allowed `TCP` and `DNS` addresses, both with `ws` or `wss` to be used for dial purposes. Taking into account security (and browser policies), we are now restricting addresses to `DNS` + `wss` in the browser
With this new behavior, if you need to use non DNS addresses, you can configure your libp2p node as follows:
```js
const Websockets = require('libp2p-websockets')
const filters = require('libp2p-websockets/src/filters')
const Libp2p = require('libp2p')
const transportKey = Websockets.prototype[Symbol.toStringTag]
const libp2p = await Libp2p.create({
modules: {
transport: [Websockets]
// ... Add required modules according to the Configuration docs
},
config: {
transport: {
[transportKey]: {
filter: filters.all
}
}
}
})
```
## Module Updates
With this release you should update the following libp2p modules if you are relying on them:
<!--Specify module versions in JSON for migration below.
It's recommended to check package.json changes for this:
`git diff <release> <prev> -- package.json`

"libp2p-floodsub": "^0.24.0",
"libp2p-gossipsub": "^0.7.0",
"libp2p-websockets": "^0.15.0",
```
Note that some of them do not need to be updated for this libp2p version to work as expected, but we suggest you to keep them updated as part of this release.

# Migrating to libp2p@31
A migration guide for refactoring your application code from libp2p v0.30.x to v0.31.0.
## Table of Contents
- [Types](#types)
- [API](#api)
- [Module Updates](#module-updates)
## Types
Most of the type definitions in the libp2p configuration were `any` or were not included before this release. This might cause breaking changes on upstream projects relying on the previous provided types, as well as to libp2p modules implemented by the libp2p community.
## API
### Core API
`libp2p.dialProtocol` does not accept empty or null protocols returning a connection anymore and `dial` must be used instead.
```js
const connection = await libp2p.dialProtocol(peerId)
```
**After**
```js
const connection = await libp2p.dial(peerId)
```
### Connection Manager Options
We updated the connection manager options naming in `libp2p@0.29` but kept it backward compatible until now.
**Before**
```js
const node = await Libp2p.create({
connectionManager: {
minPeers: 0
}
})
```
**After**
```js
const node = await Libp2p.create({
connectionManager: {
minConnections: 0
}
})
```
You can see full details on how to configure the connection manager [here](https://github.com/libp2p/js-libp2p/blob/master/doc/CONFIGURATION.md#configuring-connection-manager).
### Dialer and Keychain components
Internal property names to create a libp2p `Dialer` and `Keychain` were updated to reflect the properties naming in the libp2p configuration. These are internal modules of libp2p core and should not impact most of the users, but as it is possible to use them separately here follow the changes:
***Before**
```js
const dialer = new Dialer({
transportManager,
peerStore,
concurrency,
perPeerLimit,
timeout,
resolvers,
addressSorter
})
const keychain = new Keychain(datastore, {
passPhrase
})
```
**After**
```js
this.dialer = new Dialer({
transportManager,
peerStore,
maxParallelDials,
maxDialsPerPeer,
dialTimeout,
resolvers,
addressSorter
})
const keychain = new Keychain(datastore, {
pass
})
```
## Module Updates
With this release you should update the following libp2p modules if you are relying on them:
<!--Specify module versions in JSON for migration below.

## Module Updates
Libp2p uses a datastore implementation for Peerstore persistence and for the DHT state. While libp2p defaults to a datastore implementation, it can receive any implementation of a datastore compliant with the [interface-datastore](https://github.com/ipfs/js-ipfs-interfaces/tree/master/packages/interface-datastore) via its configuration.
In this release, we updated to `interface-datastore@6.0.0`. As a result, libp2p users relying on a configured datastore should update it to a compliant implementation for updating libp2p.

# Production
Nowadays, you can run JavaScript code in several different environments, some of them with their own particularities. Moreover, you can use `js-libp2p` for a wide range of use cases. Different environments and different use cases mean different configurations and challenges in the network.
Libp2p nodes can vary from nodes behind an application, to infrastructure nodes that enable the network to operate and to be efficient. In this context, the Libp2p project provides public infrastructure to boost the network, enable nodes connectivity and improve constrained nodes performance. This public infrastructure should be leveraged for learning the concepts and experimenting. When an application on top of libp2p aims to move into production, its own infrastructure should be setup as the public nodes will be intensively used by others and its availability is not guaranteed.
This guide aims to guide you from using the public infrastructure into setting up your own.

## Joining the Network
Once a libp2p node stars, it will need to connect to a set of peers in order to establish its overlay network.
Currently `js-libp2p` is not the best choice for being a bootstrap node. Its DHT needs to be improved, in order to become an effective server to enable other nodes to properly bootstrap their network.
Setting up a fleet of [`go-libp2p`](https://github.com/libp2p/go-libp2p) nodes is the recommended way to proceed here.
## Connecting to Nodes with connectivity limitations
While the libp2p core codebase aims to work in multiple environments, there are some limitations that are not possible to overcome at the time of writing. These limitations include browser nodes, nodes behind NAT, reverse proxies, firewalls, or lack of compatible transports.
In the browser, libp2p supports two transports: `websockets` and `webrtc-star`. Nowadays, browsers do not support listening for connections, but only to dial known addresses. `webrtc-star` servers can be used to enable libp2p nodes to discover other nodes running on the browser and to help them establish a connection.
For nodes that cannot be dialed (including browser), circuit relay nodes should be used.
### `webrtc-star` servers
Regarding `webRTC` connections, a set of star servers are needed to act as a rendezvous point, where peers can learn about other peers (`peer-discovery`), as well as exchange their SDP offers (signaling data).
You can read on how to setup your own star servers in [libp2p/js-libp2p-webrtc-star/DEPLOYMENT.md](https://github.com/libp2p/js-libp2p-webrtc-star/blob/master/DEPLOYMENT.md).
It is worth pointing out that with new discovery protocols on the way, as well as support for distributed signaling, the star servers should be deprecated on the long run.
### Circuit Relay
Libp2p nodes acting as circuit relay aim to establish connectivity between libp2p nodes (e.g. IPFS nodes) that wouldn't otherwise be able to establish a direct connection to each other.
A relay is needed in situations where nodes are behind NAT, reverse proxies, firewalls and/or simply don't support the same transports (e.g. go-libp2p vs. browser-libp2p). The circuit relay protocol exists to overcome those scenarios. Nodes with the `auto-relay` feature enabled can automatically bind themselves on a relay to listen for connections on their behalf.
You can use [libp2p/js-libp2p-relay-server](https://github.com/libp2p/js-libp2p-relay-server) to setup your own relay server. This also includes an easy to customize Docker setup for a HOP Relay.
## Querying the network from the browser
Libp2p nodes in scenarios such as browser environment and constrained devices will not be an efficient node in the libp2p DHT overlay, as a consequence of their known limitations regarding connectivity and performance.
Aiming to support these type of nodes to find other peers and content in the network, delegate nodes can be setup. With a set of well known IPFS delegate nodes, nodes with limitations in the network can leverage them to perform peer and content routing queries.
Currently, delegate nodes must be IPFS nodes as the IPFS HTTP API is leveraged by them to make routing queries.
You can read on how to setup your own set of delegated nodes in [DELEGATE_NODES.md](./DELEGATE_NODES.md).

# Auto relay
Auto Relay enables libp2p nodes to dynamically find and bind to relays on the network. Once binding (listening) is done, the node can and should advertise its addresses on the network, allowing any other node to dial it over its bound relay(s).
While direct connections to nodes are preferable, it's not always possible to do so due to NATs or browser limitations.
## 0. Setup the example
Before moving into the examples, you should run `npm install` on the top level `js-libp2p` folder, in order to install all the dependencies needed for this example. Once the install finishes, you should move into the example folder with `cd examples/auto-relay`.
This example comes with 3 main files. A `relay.js` file to be used in the first step, a `listener.js` file to be used in the second step and a `dialer.js` file to be used on the third step. All of these scripts will run their own libp2p node, which will interact with the previous ones. All nodes must be running in order for you to proceed.
## 1. Set up a relay node
In the first step of this example, we need to configure and run a relay node in order for our target node to bind to for accepting inbound connections.
The relay node will need to have its relay subsystem enabled, as well as its HOP capability. It can be configured as follows:
```js
const Libp2p = require('libp2p')
const Websockets = require('libp2p-websockets')
const { NOISE } = require('@chainsafe/libp2p-noise')
const MPLEX = require('libp2p-mplex')
const node = await Libp2p.create({
modules: {
transport: [Websockets],
connEncryption: [NOISE],
streamMuxer: [MPLEX]
},
addresses: {
listen: ['/ip4/0.0.0.0/tcp/0/ws']
// TODO check "What is next?" section
// announce: ['/dns4/auto-relay.libp2p.io/tcp/443/wss/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3']
},
config: {
relay: {
enabled: true,
hop: {
enabled: true
},
advertise: {
enabled: true,
}
}
}
})
await node.start()
console.log(`Node started with id ${node.peerId.toB58String()}`)
console.log('Listening on:')
node.multiaddrs.forEach((ma) => console.log(`${ma.toString()}/p2p/${node.peerId.toB58String()}`))
```
The Relay HOP advertise functionality is **NOT** required to be enabled. However, if you are interested in advertising on the network that this node is available to be used as a HOP Relay you can enable it. A content router module or Rendezvous needs to be configured to leverage this option.
You should now run the following to start the relay node:
```sh
node relay.js
```
This should print out something similar to the following:
```sh
Node started with id QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
Listening on:
/ip4/127.0.0.1/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
/ip4/192.168.1.120/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
```
## 2. Set up a listener node with Auto Relay Enabled
One of the typical use cases for Auto Relay is nodes behind a NAT or browser nodes due to their inability to expose a public address. For running a libp2p node that automatically binds itself to connected HOP relays, you can see the following:
```js
const Libp2p = require('libp2p')
const Websockets = require('libp2p-websockets')
const { NOISE } = require('@chainsafe/libp2p-noise')
const MPLEX = require('libp2p-mplex')
const relayAddr = process.argv[2]
if (!relayAddr) {
throw new Error('the relay address needs to be specified as a parameter')
}
const node = await Libp2p.create({
modules: {
transport: [Websockets],
connEncryption: [NOISE],
streamMuxer: [MPLEX]
},
config: {
relay: {
enabled: true,
autoRelay: {
enabled: true,
maxListeners: 2
}
}
}
})
await node.start()
console.log(`Node started with id ${node.peerId.toB58String()}`)
const conn = await node.dial(relayAddr)
// Wait for connection and relay to be bind for the example purpose
await new Promise((resolve) => {
node.peerStore.on('change:multiaddrs', ({ peerId }) => {
// Updated self multiaddrs?
if (peerId.equals(node.peerId)) {
resolve()
}
})
})
console.log(`Connected to the HOP relay ${conn.remotePeer.toString()}`)
console.log(`Advertising with a relay address of ${node.multiaddrs[0].toString()}/p2p/${node.peerId.toB58String()}`)
```
As you can see in the code, we need to provide the relay address, `relayAddr`, as a process argument. This node will dial the provided relay address and automatically bind to it.
You should now run the following to start the node running Auto Relay:
```sh
node listener.js /ip4/192.168.1.120/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
```
This should print out something similar to the following:
```sh
Node started with id QmerrWofKF358JE6gv3z74cEAyL7z1KqhuUoVfGEynqjRm
Connected to the HOP relay QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
Advertising with a relay address of /ip4/192.168.1.120/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3/p2p-circuit/p2p/QmerrWofKF358JE6gv3z74cEAyL7z1KqhuUoVfGEynqjRm
```
Per the address, it is possible to verify that the auto relay node is listening on the circuit relay node address.
Instead of dialing this relay manually, you could set up this node with the Bootstrap module and provide it in the bootstrap list. Moreover, you can use other `peer-discovery` modules to discover peers in the network and the node will automatically bind to the relays that support HOP until reaching the maximum number of listeners.
## 3. Set up a dialer node for testing connectivity
Now that you have a relay node and a node bound to that relay, you can test connecting to the auto relay node via the relay.
```js
const Libp2p = require('libp2p')
const Websockets = require('libp2p-websockets')
const { NOISE } = require('@chainsafe/libp2p-noise')
const MPLEX = require('libp2p-mplex')
const autoRelayNodeAddr = process.argv[2]
if (!autoRelayNodeAddr) {
throw new Error('the auto relay node address needs to be specified')
}
const node = await Libp2p.create({
modules: {
transport: [Websockets],
connEncryption: [NOISE],
streamMuxer: [MPLEX]
}
})
await node.start()
console.log(`Node started with id ${node.peerId.toB58String()}`)
const conn = await node.dial(autoRelayNodeAddr)
console.log(`Connected to the auto relay node via ${conn.remoteAddr.toString()}`)
```
You should now run the following to start the relay node using the listen address from step 2:
```sh
node dialer.js /ip4/192.168.1.120/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3
```
Once you start your test node, it should print out something similar to the following:
```sh
Node started: Qme7iEzDxFoFhhkrsrkHkMnM11aPYjysaehP4NZeUfVMKG
Connected to the auto relay node via /ip4/192.168.1.120/tcp/61592/ws/p2p/QmWDn2LY8nannvSWJzruUYoLZ4vV83vfCBwd8DipvdgQc3/p2p-circuit/p2p/QmerrWofKF358JE6gv3z74cEAyL7z1KqhuUoVfGEynqjRm
```
As you can see from the output, the remote address of the established connection uses the relayed connection.
## 4. What is next?
Before moving into production, there are a few things that you should take into account.
A relay node should not advertise its private address in a real world scenario, as the node would not be reachable by others. You should provide an array of public addresses in the libp2p `addresses.announce` option. If you are using websockets, bear in mind that due to browsers security policies you cannot establish unencrypted connection from secure context. The simplest solution is to setup SSL with nginx and proxy to the node and setup a domain name for the certificate.

## 3. Pubsub based Peer Discovery ## 3. Where to find other Peer Discovery Mechanisms
For this example, we need [`libp2p-pubsub-peer-discovery`](https://github.com/libp2p/js-libp2p-pubsub-peer-discovery/), go ahead and `npm install` it. You also need to spin up a set of [`libp2p-relay-servers`](https://github.com/libp2p/js-libp2p-relay-server). These servers act as relay servers and a peer discovery source.
In the context of this example, we will create and run the `libp2p-relay-server` in the same code snippet. You can find the complete solution at [3.js](./3.js).
You can create your libp2p nodes as follows:
```js
const Libp2p = require('libp2p')
const TCP = require('libp2p-tcp')
const Mplex = require('libp2p-mplex')
const { NOISE } = require('@chainsafe/libp2p-noise')
const Gossipsub = require('libp2p-gossipsub')
const Bootstrap = require('libp2p-bootstrap')
const PubsubPeerDiscovery = require('libp2p-pubsub-peer-discovery')
const createNode = async (bootstrapers) => {
const node = await Libp2p.create({
addresses: {
listen: ['/ip4/0.0.0.0/tcp/0']
},
modules: {
transport: [TCP],
streamMuxer: [Mplex],
connEncryption: [NOISE],
pubsub: Gossipsub,
peerDiscovery: [Bootstrap, PubsubPeerDiscovery]
},
config: {
peerDiscovery: {
[PubsubPeerDiscovery.tag]: {
interval: 1000,
enabled: true
},
[Bootstrap.tag]: {
enabled: true,
list: bootstrapers
}
}
}
})
return node
}
```
We will use the `libp2p-relay-server` as bootstrap nodes for the libp2p nodes, so that they establish a connection with the relay after starting. As a result, after they establish a connection with the relay, the pubsub discovery will kick in and the relay will advertise them.
```js
const relay = await createRelayServer({
listenAddresses: ['/ip4/0.0.0.0/tcp/0']
})
console.log(`libp2p relay starting with id: ${relay.peerId.toB58String()}`)
await relay.start()
const relayMultiaddrs = relay.multiaddrs.map((m) => `${m.toString()}/p2p/${relay.peerId.toB58String()}`)
const [node1, node2] = await Promise.all([
createNode(relayMultiaddrs),
createNode(relayMultiaddrs)
])
node1.on('peer:discovery', (peerId) => {
console.log(`Peer ${node1.peerId.toB58String()} discovered: ${peerId.toB58String()}`)
})
node2.on('peer:discovery', (peerId) => {
console.log(`Peer ${node2.peerId.toB58String()} discovered: ${peerId.toB58String()}`)
})
;[node1, node2].forEach((node, index) => console.log(`Node ${index} starting with id: ${node.peerId.toB58String()}`))
await Promise.all([
node1.start(),
node2.start()
])
```
If you run this example, you will see the other peers being discovered.
```bash
> node 3.js
libp2p relay starting with id: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
Node 0 starting with id: QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N
Node 1 starting with id: QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv
Peer QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N discovered: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
Peer QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv discovered: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
Peer QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv discovered: QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N
Peer QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N discovered: QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv
```
Taking into account the output, after the relay and both libp2p nodes start, both libp2p nodes will discover the bootstrap node (relay) and connect with it. After establishing a connection with the relay, they will discover each other.
This is really useful when running libp2p in constrained environments like a browser. You can run a set of `libp2p-relay-server` nodes that will be responsible for both relaying websocket connections between browser nodes and for discovering other browser peers.
## 4. Where to find other Peer Discovery Mechanisms
There are plenty more Peer Discovery Mechanisms out there, you can: There are plenty more Peer Discovery Mechanisms out there, you can:
- Find one in [libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star). Yes, a transport with discovery capabilities! This happens because WebRTC requires a rendezvous point for peers to exchange [SDP](https://tools.ietf.org/html/rfc4317) offer, which means we have one or more points that can introduce peers to each other. Think of it as MulticastDNS for the Web, as in MulticastDNS only works in LAN. - Find one in [libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star).

- Any DHT will offer you a discovery capability. You can simple _random-walk_ the routing tables to find other peers to connect to. For example [libp2p-kad-dht](https://github.com/libp2p/js-libp2p-kad-dht) can be used for peer discovery. An example of how to configure it to enable random walks can be found [here](https://github.com/libp2p/js-libp2p/blob/v0.28.4/doc/CONFIGURATION.md#customizing-dht). - Any DHT will offer you a discovery capability.

Before moving into the examples, you should run `npm install` on the top level `js-libp2p` folder, in order to install all the dependencies needed for this example. In addition, you will need to install the example related dependencies by doing `cd examples && npm install`. Once the install finishes, you should move into the example folder with `cd pubsub`.

### Webrtc-direct example
An example that uses [js-libp2p-webrtc-direct](https://github.com/libp2p/js-libp2p-webrtc-direct) for connecting
nodejs libp2p and browser libp2p clients. To run the example:
## 0. Run a nodejs libp2p listener
When in the root folder of this example, type `node listener.js` in terminal. You should see an address that listens for
incoming connections. Below is just an example of such address. In your case the suffix hash (`peerId`) will be different.
```bash
$ node listener.js
Listening on:
/ip4/127.0.0.1/tcp/9090/http/p2p-webrtc-direct/p2p/QmUKQCzEUhhhobcNSrXU5uzxTqbvF1BjMCGNGZzZU14Kgd
```
## 1. Prepare a browser libp2p dialer
Confirm that the above address is the same as the field `list` in `public/dialer.js`:
```js
peerDiscovery: {
[Bootstrap.tag]: {
enabled: true,
// paste the address into `list`
list: ['/ip4/127.0.0.1/tcp/9090/http/p2p-webrtc-direct/p2p/QmUKQCzEUhhhobcNSrXU5uzxTqbvF1BjMCGNGZzZU14Kgd']
}
}
```
## 2. Run a browser libp2p dialer
When in the root folder of this example, type `npm run dev` in terminal. You should see an address where you can browse
the running client. Open this address in your browser. In console
logs you should see logs about successful connection with the node client. In the output of node client you should see
a log message about successful connection as well.
