To sum up, libp2p is a "network stack" -- a protocol suite -- that cleanly separates concerns, and enables sophisticated applications to only use the protocols they absolutely need, without giving up interoperability and upgradeability. libp2p grew out of IPFS, but it is built so that lots of people can use it, for lots of different projects.
|
||||
|
||||
## Bundles
|
||||
|
||||
With its modular nature, libp2p can be found being used in different projects with different sets of features, while preserving the same top level API. `js-libp2p` is only a skeleton and should not be installed directly, if you are looking for a prebundled libp2p stack, please check:
|
||||
|
||||
- [libp2p-ipfs-nodejs](https://github.com/ipfs/js-ipfs/tree/master/src/core/runtime/libp2p-nodejs.js) - The libp2p build used by js-ipfs when run in Node.js
|
||||
- [libp2p-ipfs-browser](https://github.com/ipfs/js-ipfs/tree/master/src/core/runtime/libp2p-browser.js) - The libp2p build used by js-ipfs when run in a Browser (that supports WebRTC)
|
||||
|
||||
If you have developed a libp2p bundle, please consider submitting it to this list so that it can be found easily by the users of libp2p.
|
||||
|
||||
## Install
|
||||
|
||||
Again, as noted above, this module is only a skeleton and should not be used directly other than libp2p bundle implementors that want to extend its code.
|
||||
|
||||
```sh
|
||||
npm install libp2p
|
||||
npm install --save libp2p
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Configuration
|
||||
**IMPORTANT NOTE**: We are currently on the way of migrating all our `libp2p` modules to use `async await` and `async iterators`, instead of callbacks and `pull-streams`. As a consequence, when you start a new libp2p project, we must check which versions of the modules you should use. For now, it is required to use the modules using callbacks with `libp2p`, while we are working on getting the remaining modules ready for a full migration. For more details, you can have a look at [libp2p/js-libp2p#266](https://github.com/libp2p/js-libp2p/issues/266).
|
||||
|
||||
For all the information on how you can configure libp2p see [CONFIGURATION.md](./doc/CONFIGURATION.md).
|
||||
### [Tutorials and Examples](/examples)
|
||||
|
||||
You can find multiple examples on the [examples folder](/examples) that will guide you through using libp2p for several scenarios.
|
||||
|
||||
### Creating your own libp2p bundle
|
||||
|
||||
The libp2p module acts as a glue for every libp2p module that you can use to create your own libp2p bundle. Creating your own libp2p bundle gives you a lot of freedom when it comes to customize it with features and default setup. We recommend creating your own libp2p bundle for the app you are developing that takes into account your needs (e.g. for a browser working version of libp2p that acts as the network layer of IPFS, we have built one that leverages the Browser transports).
|
||||
|
||||
**Example:**
|
||||
|
||||
```JavaScript
|
||||
// Creating a bundle that adds:
|
||||
// transport: websockets + tcp
|
||||
// stream-muxing: spdy & mplex
|
||||
// crypto-channel: secio
|
||||
// discovery: multicast-dns
|
||||
|
||||
const Libp2p = require('libp2p')
|
||||
const TCP = require('libp2p-tcp')
|
||||
const WS = require('libp2p-websockets')
|
||||
const SPDY = require('libp2p-spdy')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const MulticastDNS = require('libp2p-mdns')
|
||||
const DHT = require('libp2p-kad-dht')
|
||||
const GossipSub = require('libp2p-gossipsub')
|
||||
const defaultsDeep = require('@nodeutils/defaults-deep')
|
||||
const Protector = require('libp2p/src/pnet')
|
||||
const DelegatedPeerRouter = require('libp2p-delegated-peer-routing')
|
||||
const DelegatedContentRouter = require('libp2p-delegated-content-routing')
|
||||
|
||||
class Node extends Libp2p {
|
||||
constructor (_options) {
|
||||
const peerInfo = _options.peerInfo
|
||||
const defaults = {

|
||||

## Events
|
||||
|
||||
Once you have a libp2p instance, you can listen to several events it emits, so that you can be notified of relevant network events.
|
||||
|
||||
#### An error has occurred
|
||||
|
||||
`libp2p.on('error', (err) => {})`
|
||||
|
||||
- `err`: instance of `Error`
|
||||
|
||||
#### A peer has been discovered
|
||||
|
||||
`libp2p.on('peer:discovery', (peer) => {})`
|
||||
|
||||
If `autoDial` option is `true`, applications should **not** attempt to connect to the peer
|
||||
unless they are performing a specific action. See [peer discovery and auto dial](./PEER_DISCOVERY.md) for more information.
|
||||
|
||||
- `peer`: instance of [`PeerInfo`][peer-info]
|
||||
|
||||
#### A new connection to a peer has been opened
|
||||
|
||||
This event will be triggered anytime a new Connection is established to another peer.
|
||||
|
||||
`libp2p.on('peer:connect', (peer) => {})`
|
||||
|
||||
- `peer`: instance of [`PeerInfo`][peer-info]
|
||||
|
||||
#### An existing connection to a peer has been closed
|
||||
|
||||
This event will be triggered anytime we are disconnected from another peer, regardless of the circumstances of that disconnection. If we happen to have multiple connections to a peer, this event will **only** be triggered when the last connection is closed.
|
||||
|
||||

#### Configuring Dialing
|
||||
|
||||
Dialing in libp2p can be configured to limit the rate of dialing, and how long dials are allowed to take. The below configuration example shows the default values for the dialer.
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')

|
||||
}
|
||||
```
|
||||
|
||||
#### Configuring Connection Manager
|
||||
|
||||
The Connection Manager prunes Connections in libp2p whenever certain limits are exceeded. If Metrics are enabled, you can also configure the Connection Manager to monitor the bandwidth of libp2p and prune connections as needed. You can read more about what Connection Manager does at [./CONNECTION_MANAGER.md](./CONNECTION_MANAGER.md). The configuration values below show the defaults for Connection Manager. See [./CONNECTION_MANAGER.md](./CONNECTION_MANAGER.md#options) for a full description of the parameters.

#### Customizing Transports
|
||||
|
||||
Some Transports can be passed additional options when they are created. For example, `libp2p-webrtc-star` accepts an optional, custom `wrtc` implementation. In addition to libp2p passing itself and an `Upgrader` to handle connection upgrading, libp2p will also pass the options, if they are provided, from `config.transport`.
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebRTCStar = require('libp2p-webrtc-star')

* Parallel dials to the same peer will yield the same connection/error when the first dial settles.
|
||||
* All Dial Requests in js-libp2p must request a token(s) from the Dialer.
|
||||
* The number of tokens requested should be between 1 and the MAX_PER_PEER_DIALS max set in the Dialer.
|
||||
* If the number of available tokens is less than requested, the Dialer may return less than requested.

|

## Install
|
||||
|
||||
The first step is to install libp2p in your project:
|
||||
|
||||
```sh
|
||||
npm install libp2p
|
||||
```
|
||||
|
||||
## Configuring libp2p
|
||||
|
||||
If you're new to libp2p, we recommend configuring your node in stages, as this can make troubleshooting configuration issues much easier. In this guide, we'll do just that. If you're more experienced with libp2p, you may wish to jump to the [Configuration readme](./CONFIGURATION.md).
|
||||
|
||||
### Basic setup
|
||||
|
||||
Now that we have libp2p installed, let's configure the minimum needed to get your node running. The only modules libp2p requires are a [**Transport**][transport] and [**Crypto**][crypto] module. However, we recommend that a basic setup should also have a [**Stream Multiplexer**](streamMuxer) configured, which we will explain shortly. Let's start by setting up a Transport.
|
||||
|
||||
#### Transports
|
||||
|
||||
Libp2p uses Transports to establish connections between peers over the network. Transports are the components responsible for performing the actual exchange of data between libp2p nodes. You can configure any number of Transports, but you only need 1 to start with. Supporting more Transports will improve the ability of your node to speak to a larger number of nodes on the network, as matching Transports are required for two nodes to communicate with one another.
|
||||
|
||||
You should select Transports according to the runtime of your application; Node.js or the browser. You can see a list of some of the available Transports in the [configuration readme](./CONFIGURATION.md#transport). For this guide let's install `libp2p-websockets`, as it can be used in both Node.js and the browser.
|
||||
|
||||
Start by installing `libp2p-websockets`:
|
||||
|
||||
```sh
|
||||
npm install libp2p-websockets
|
||||
```
|
||||
|
||||
Now that we have the module installed, let's configure libp2p to use the Transport. We'll use the [`Libp2p.create`](./API.md#create) method, which takes a single configuration object as its only parameter. We can add the Transport by passing it into the `modules.transport` array:
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebSockets = require('libp2p-websockets')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [WebSockets]
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
There are multiple libp2p transports available, you should evaluate the needs of your application and select the Transport(s) that best suit your requirements. You can add as many transports as you like to `modules.transport` in order to establish connections with as many peers as possible.

|

</details>
|
||||
|
||||
#### Connection Encryption
|
||||
|
||||
Encryption is an important part of communicating on the libp2p network. Every connection must be encrypted to help ensure security for everyone. As such, Connection Encryption (Crypto) is a required component of libp2p.
|
||||
|
||||
There are a growing number of Crypto modules being developed for libp2p. As those are released they will be tracked in the [Connection Encryption section of the configuration readme](./CONFIGURATION.md#connection-encryption). For now, we are going to configure our node to use the `libp2p-secio` module, which is widely supported across the various libp2p implementations.
|
||||
|
||||
```sh
|
||||
npm install libp2p-secio
|
||||
```
|
||||
|
||||
With `libp2p-secio` installed, we can add it to our existing configuration by importing it and adding it to the `modules.connEncryption` array:
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebSockets = require('libp2p-websockets')
|
||||
const SECIO = require('libp2p-secio')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [WebSockets],
|
||||
connEncryption: [SECIO]
|
||||
}
|
||||
})
|
||||
```

||||

|
||||
</details>
|
||||
|
||||
#### Multiplexing
|
||||
|
||||
While multiplexers are not strictly required, they are highly recommended as they improve the effectiveness and efficiency of connections for the various protocols libp2p runs. Adding a multiplexer to your configuration will allow libp2p to run several of its internal protocols, like Identify, as well as allow your application to easily run any number of protocols over a single connection.
|
||||
|
||||
Looking at the [available stream multiplexing](./CONFIGURATION.md#stream-multiplexing) modules, js-libp2p currently only supports `libp2p-mplex`, so we will use that here. Bear in mind that future libp2p Transports might have `multiplexing` capabilities already built-in (such as `QUIC`).
|
||||
|
||||
You can install `libp2p-mplex` and add it to your libp2p node as follows in the next example.
|
||||
|
||||
```sh
|
||||
npm install libp2p-mplex
|
||||
```
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebSockets = require('libp2p-websockets')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [WebSockets],
|
||||
connEncryption: [SECIO],
|
||||
streamMuxer: [MPLEX]
|
||||
}
|
||||
})
|
||||

|
||||
|
||||
#### Running Libp2p
|
||||
|
||||
Now that you have configured a [**Transport**][transport], [**Crypto**][crypto] and [**Stream Multiplexer**](streamMuxer) module, you can start your libp2p node. We can start and stop libp2p using the [`libp2p.start()`](./API.md#start) and [`libp2p.stop()`](./API.md#stop) methods.
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebSockets = require('libp2p-websockets')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [WebSockets],
|
||||
connEncryption: [SECIO],
|
||||
streamMuxer: [MPLEX]
|
||||
}
|
||||
})
|
||||
|
||||
// start libp2p
|
||||
await node.start()
|
||||
console.log('libp2p has started')
|
||||
|
||||
// stop libp2p
|
||||
await node.stop()
|
||||
console.log('libp2p has stopped')
|
||||
```
|
||||
|
||||
### Custom setup
|
||||
|
||||
Once your libp2p node is running, it is time to get it connected to the public network. We can do this via peer discovery.
|
||||
|
||||
#### Peer Discovery
|
||||
|
||||
Peer discovery is an important part of creating a well connected libp2p node. A static list of peers will often be used to join the network, but it's useful to couple other discovery mechanisms to ensure you're able to discover other peers that are important to your application.
|
||||
|
||||
For each discovered peer libp2p will emit a `peer:discovery` event which includes metadata about that peer. You can read the [Events](./API.md#events) in the API doc to learn more.
|
||||
|
||||
Looking at the [available peer discovery](./CONFIGURATION.md#peer-discovery) protocols, there are several options to be considered:
|
||||
- If you already know the addresses of some other network peers, you should consider using `libp2p-bootstrap` as this is the easiest way of getting your peer into the network.
|
||||
- If it is likely that you will have other peers on your local network, `libp2p-mdns` is a must if you're node is not running in the browser. It allows peers to discover each other when on the same local network.
|
||||
- If your application is browser based you can use the `libp2p-webrtc-star` Transport, which includes a rendezvous based peer sharing service.
|
||||
- A random walk approach can be used via `libp2p-kad-dht`, to crawl the network and find new peers along the way.
|
||||
|
||||
For this guide we will configure `libp2p-bootstrap` as this is useful for joining the public network.
|
||||
|
||||
Let's install `libp2p-bootstrap`.
|
||||
|
||||
```sh
|
||||
npm install libp2p-bootstrap
|
||||
```
|
||||
|
||||
We can provide specific configurations for each protocol within a `config.peerDiscovery` property in the options as shown below.
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const WebSockets = require('libp2p-websockets')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
|
||||
const Bootstrap = require('libp2p-bootstrap')
|
||||
|
||||
// Known peers addresses
|
||||
const bootstrapMultiaddrs = [
|
||||
'/dns4/ams-1.bootstrap.libp2p.io/tcp/443/wss/p2p/QmSoLer265NRgSp2LA3dPaeykiS1J6DifTC88f5uVQKNAd',

# Migrating to the new API
|
||||
|
||||
A migration guide for refactoring your application code from libp2p v0.26.x to v0.27.0.

|
||||
## Migrating from callbacks
|
||||
|
||||
Callbacks are no longer supported in the libp2p API, as the API has now fully moved to async / await. You can see a full list of the available methods in the [API readme][api]
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.start((err) => {
|
||||
if (err) throw err
|
||||
console.log('libp2p started')
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
await libp2p.start()
|
||||
console.log('libp2p started')
|
||||
```
|
||||
|
||||
## Pull Streams to Streaming Iterables
|
||||
|
||||
The libp2p API no longer supports Pull Streams and has migrated to [Streaming Iterables][streaming_iterable]. If you would like to continue using Pull Streams in your application code, or need additional time to migrate your code base, you can leverage the conversion modules [async-iterator-to-pull-stream](https://github.com/alanshaw/async-iterator-to-pull-stream) and [pull-stream-to-async-iterator](https://github.com/alanshaw/pull-stream-to-async-iterator).
|
||||
|
||||
For a growing list of async iterator modules, you should follow the [it-awesome repo][it_awesome].
|
||||
|
||||
## Sample API Migrations
|
||||
|
||||
### Registering Protocol Handlers
|
||||
|
||||
Protocol registration is very similar to how it previously was, however, the handler now takes a single parameter containing the incoming stream and its protocol. Additionally, you can now pass an array of protocols to `.handle`, but a single string is still supported.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const pull = require('pull-stream')
|
||||
libp2p.handle('/echo/1.0.0', (protocol, conn) => pull(conn, conn))
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const pipe = require('it-pipe')
|
||||
libp2p.handle(['/echo/1.0.0'], ({ protocol, stream }) => pipe(stream, stream))
|
||||
```
|
||||
|
||||
### Dialing and Sending Data
|
||||
|
||||
`dialProtocol` no longer takes a callback, and will now return a [Streaming Iterable][streaming_iterable] and the protocol that was successfully negotiated. The new stream can be used with async iterator modules, see [it-awesome][it_awesome], instead of pull streams.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const pull = require('pull-stream')
|
||||
libp2p.dialProtocol(peerInfo, '/echo/1.0.0', (err, conn) => {
|
||||
if (err) { throw err }
|
||||
pull(
|
||||
pull.values(['hey']),
|
||||
conn,
|
||||
pull.drain((data) => {
|
||||
console.log('received echo:', data.toString())
|
||||
}, (err) => {
|
||||
if (err) { throw err }
|
||||
})
|
||||
)
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const pipe = require('it-pipe')
|
||||
const { protocol, stream } = await libp2p.dialProtocol(peerInfo, '/echo/1.0.0')
|
||||
await pipe(
|
||||
['hey'],
|
||||
stream,
|
||||
async function (source) {
|
||||
for await (const data of source) {
|
||||
console.log('received echo:', data.toString())
|
||||
}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### Checking if a peer is connected
|
||||
|
||||
`peerInfo.isConnected` has been deprecated. libp2p now tracks all connections centrally and will no longer update the state of `peerInfo.isConnected`. Consumers should switch to using `libp2p.registrar.getConnection(peerInfo)`, which will return an open connection to that peer if one exists.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
if (peerInfo.isConnected()) {
|
||||
// ...do something if connected
|
||||
}
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const connection = libp2p.registrar.getConnection(peerInfo)
|
||||
if (connection) {
|
||||
// ...do something if connected
|
||||
}
|
||||
```
|
||||
|
||||
### Pinging another peer
|
||||
|
||||
`libp2p.ping` will no longer callback with a `Ping` event emitter. The internal logic has been simplified to give more flexibility to the API. `libp2p.ping` will now execute a single ping and return the latency.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.ping(peerInfo, (err, ping) => {
|
||||
if (err) throw err
|
||||
ping.once('ping', (latency) => {
|
||||
console.log('Latency is %s ms', latency)
|
||||
ping.stop()
|
||||
})
|
||||
|
||||
ping.start()
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const latency = await libp2p.ping(peerInfo)
|
||||
console.log('Latency is %s ms', latency)
|
||||
```
|
||||
|
||||
### Pubsub
|
||||
|
||||
#### Getting subscribers
|
||||
|
||||
`libp2p.pubsub.peers()` is now `libp2p.pubsub.getSubscribers()` and is no longer an asynchronous action.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.pubsub.peers(topic, (err, subscribers) => {
|
||||
if (err) throw err
|
||||
console.log('Subscribers:', subscribers)
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const subscribers = libp2p.pubsub.getSubscribers(topic)
|
||||
console.log('Subscribers:', subscribers)
|
||||
```
|
||||
|
||||
#### Getting subscribed topics
|
||||
|
||||
`libp2p.pubsub.ls()` is now `libp2p.pubsub.getTopics()` and is no longer an asynchronous action.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.pubsub.ls((err, topics) => {
|
||||
if (err) throw err
|
||||
console.log('Topics:', topics)
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const topics = libp2p.pubsub.getTopics()
|
||||
console.log('Topics:', topics)

## 2. MulticastDNS to find other peers in the network
|
||||
|
||||
For this example, we need `libp2p-mdns`, go ahead and `npm install` it. You can find the complete solution at [2.js](./2.js).
|
||||
|
||||
Update your libp2p configuration to include MulticastDNS.
|
||||
Update your libp2p bundle to include MulticastDNS.
|
||||
|
||||
```JavaScript
|
||||
const Libp2p = require('libp2p')
|
||||
const MulticastDNS = require('libp2p-mdns')
|
||||
|
||||
const createNode = () => {
|

return Libp2p.create({

|
||||
```
|
||||
|
||||
To observe it working, spawn two nodes.
|
||||
|
||||
```JavaScript
|
||||
const [node1, node2] = await Promise.all([
|
||||
createNode(),
|
||||
createNode()
|
||||
])
|
||||

node2.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
|
||||
})
|
||||
```
|
||||
|
||||
If you run this example, you will see the other peers being discovered.

A byproduct of having these encrypted communications modules is that we can authenticate the peers we are dialing to. You might have noticed that every time we dial to a peer in libp2p space, we always use its PeerId at the end (e.g /ip4/127.0.0.1/tcp/89765/p2p/QmWCbVw1XZ8hiYBwwshPce2yaTDYTqTaP7GCHGpry3ykWb), this PeerId is generated by hashing the Public Key of the peer. With this, we can create a crypto challenge when dialing to another peer and prove that peer is the owner of a PrivateKey that matches the Public Key we know.

# libp2p in the browser

# libp2p running in the Browser
|
||||
|
||||
This example leverages the [Parcel.js bundler](https://parceljs.org/) to compile and serve the libp2p code in the browser. Parcel uses [Babel](https://babeljs.io/) to handle transpilation of the code. You can use other bundlers such as Webpack or Browserify, but we will not be covering them here.
|
||||
One of the primary goals with libp2p P2P was to get it fully working in the browser and interopable with the versions running in Go and in Node.js.
|
||||
|
||||
## Setup
|
||||
# 1. Setting up a simple app that lists connections to other nodes
|
||||
|
||||
In order to run the example, first install the dependencies from same directory as this README:
|
||||
Start by installing libp2p's dependencies.
|
||||
|
||||
```
|
||||
cd ./examples/libp2p-in-the-browser
|
||||
npm install
|
||||
```bash
|
||||
> cd ../../
|
||||
> npm install
|
||||
> cd examples/libp2p-in-the-browser
|
||||
```
|
||||
|
||||
## Signaling Server
|
||||
Then simply go into the folder [1](./1) and execute the following
|
||||
|
||||
This example uses the `libp2p-webrtc-star` module, which enables libp2p browser nodes to establish direct connections to one another via a central signaling server. For this example, we are using the signaling server that ships with `libp2p-webrtc-star`.
|
||||
|
||||
You can start the server by running `npm run server`. This will start a signaling server locally on port `9090`. If you'd like to run a signaling server outside of this example, you can see instructions on how to do so in the [`libp2p-webrtc-star` README](https://github.com/libp2p/js-libp2p-webrtc-star).
|
||||
|
||||
When you run the server, you should see output that looks something like this:
|
||||
|
||||
```log
|
||||
$ npm run server
|
||||
|
||||
> libp2p-in-browser@1.0.0 server
|
||||
> star-signal
|
||||
|
||||
Listening on: http://0.0.0.0:9090
|
||||
```bash
|
||||
> cd 1
|
||||
> npm install
|
||||
> npm start
|
||||
# open your browser in port :9090
|
||||
```
|
||||
|
||||
## Running the examples
|
||||
|
||||
Once you have started the signaling server, you can run the Parcel server.
|
||||
|
||||
```
|
||||
npm start
|
||||
```
|
||||
|
||||
The output should look something like this:
|
||||
|
||||
```log
|
||||
$ npm start
|
||||
|
||||
> libp2p-in-browser@1.0.0 start
|
||||
> parcel index.html
|
||||
|
||||
Server running at http://localhost:1234
|
||||
✨ Built in 1000ms.
|
||||
```
|
||||
|
||||
This will compile the code and start a server listening on port [http://localhost:1234](http://localhost:1234). Now open your browser to `http://localhost:1234`. You should see a log of your node's Peer ID, the discovered peers from the Bootstrap module, and connections to those peers as they are created.
|
||||
|
||||
Now, if you open a second browser tab to `http://localhost:1234`, you should discover your node from the previous tab. This is due to the fact that the `libp2p-webrtc-star` transport also acts as a Peer Discovery interface. Your node will be notified of any peer that connects to the same signaling server you are connected to. Once libp2p discovers this new peer, it will attempt to establish a direct WebRTC connection.
|
||||
|
||||
**Note**: In the example we assign libp2p to `window.libp2p`, in case you would like to play around with the API directly in the browser. You can of course make changes to `index.js` and Parcel will automatically rebuild and reload the browser tabs.

This feature is super power for network protocols. It works in the same way as versioning your RPC/REST API, but for anything that goes in the wire. We had to use this feature to upgrade protocols within the IPFS Stack (i.e Bitswap) and we successfully managed to do so without any network splits.
|
||||
|
||||
There is still one last feature, you can provide multiple protocols for the same handler. If you have a backwards incompatible change, but it only requires minor changes to the code, you may prefer to do protocol checking instead of having multiple handlers

There is still one last feature, you can create your custom match functions.

# 2. Reuse existing connection

The examples above would require a node to create a whole new connection for every time it dials in one of the protocols, this is a waste of resources and also it might be simply not possible (e.g lack of file descriptors, not enough ports being open, etc). What we really want is to dial a connection once and then multiplex several virtual connections (stream) over a single connection, this is where _stream multiplexing_ comes into play.

Stream multiplexing is an old concept, in fact it happens in many of the layers of the [OSI System](https://en.wikipedia.org/wiki/OSI_model). In libp2p, we make this feature to our avail by letting the user pick which module for stream multiplexing to use.

Using PubSub is super simple, you only need to provide the implementation of your choice and you are ready to go. No need for extra configuration.
|
||||
|
||||
First, let's update our libp2p configuration with a pubsub implementation.
|
||||
|
||||
```JavaScript
|
||||
const Libp2p = require('libp2p')
|
||||
const Gossipsub = require('libp2p-gossipsub')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [ TCP ],
|
||||
streamMuxer: [ Mplex ],
|
||||
connEncryption: [ SECIO ],
|
||||
// we add the Pubsub module we want
|
||||
pubsub: Gossipsub
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
Once that is done, we only need to create a few libp2p nodes, connect them and everything is ready to start using pubsub.
|
||||
|
||||
```JavaScript
|
||||
const topic = 'news'
|
||||
|
||||
const node1 = nodes[0]
|

const node2 = nodes[1]
|

|

await node1.dial(node2.peerInfo)
|

|

await node1.pubsub.subscribe(topic, (msg) => {

console.log(`node1 received: ${msg.data.toString()}`)

|

libp2p doesn't make assumptions for you, instead, it enables you as the developer of the application to pick the modules you need to run your application, which can vary depending on the runtime you are executing. A libp2p node can use one or more Transports to dial and listen for Connections. These transports are modules that offer a clean interface for dialing and listening, defined by the [interface-transport](https://github.com/libp2p/js-interfaces/tree/master/src/transport) specification. Some examples of possible transports are: TCP, UTP, WebRTC, QUIC, HTTP, Pigeon and so on.

When using libp2p, you need properly configure it, that is, pick your set of modules and create your network stack with the properties you need. In this example, we will create a libp2p node TCP. You can find the complete solution on the file [1.js](./1.js).

When using libp2p, you always want to create your own libp2p Bundle, that is, pick your set of modules and create your network stack with the properties you need. In this example, we will create a bundle with TCP. You can find the complete solution on the file [1.js](./1.js).

You will need 4 dependencies total, so go ahead and install all of them with:

## 2. Dialing from one node to another node

|

Now that we have our bundle, let's create two nodes and make them dial to each other! You can find the complete solution at [2.js](./2.js).
|
||||
|
||||
For this step, we will need one more dependency.
|
||||
|
||||
```bash
|
||||
> npm install it-pipe it-buffer
|
||||
> npm install pull-stream
|
||||
```
|
||||
|
||||
And we also need to import the module on our .js file:
|
||||
|
||||
```js
|
||||
const pipe = require('it-pipe')
|
||||
const { toBuffer } = require('it-buffer')
|
||||
const pull = require('pull-stream')
|
||||
```
|
||||
|
||||
We are going to reuse the `createNode` function from step 1, but this time to make things simpler, we will create another function to print the addrs to avoid duplicating code.
|
||||
We are going to reuse the MyBundle class from step 1, but this time to make things simpler, we will create two functions, one to create nodes and another to print the addrs to avoid duplicating code.
|
||||
|
||||
```JavaScript
|
||||
function createNode (callback) {
|
||||
let node
|
||||

||||
waterfall([
|
||||
(cb) => PeerInfo.create(cb),
|
||||
(peerInfo, cb) => {
|
||||
peerInfo.multiaddrs.add('/ip4/0.0.0.0/tcp/0')
|
||||
node = new MyBundle({ peerInfo: peerInfo })
|
||||
node.start(cb)
|
||||
}
|
||||

|
||||
function printAddrs (node, number) {

console.log('node %s is listening on:', number)
|

node.peerInfo.multiaddrs.forEach((ma) => console.log(ma.toString()))
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Now we are going to use `async/parallel` to create two nodes, print their addresses and dial from one node to the other. We already added `async` as a dependency, but still need to import `async/parallel`:
|
||||
|
||||
```js
|
||||
const parallel = require('async/parallel')

`print` is a function created using the code from 2.js, but factored into its own function to save lines, here it is:
|
||||
|
||||
```JavaScript
|
||||
function print ({ stream }) {
|
||||
pipe(
|
||||
stream,
|
||||
async function (source) {
|
||||
for await (const msg of source) {
|
||||
console.log(msg.toString())
|
||||
}
|
||||
}
|
||||
function print (protocol, conn) {
|
||||
pull(
|
||||
conn,
|
||||
pull.map((v) => v.toString()),
|
||||
pull.log()
|
||||
)
|
||||
}
|
||||
```

As expected, we created 3 nodes, node 1 with TCP, node 2 with TCP+WebSockets and node 3 with just WebSockets. node 1 -> node 2 and node 2 -> node 3 managed to dial correctly because they shared a common transport, however, node 3 -> node 1 failed because they didn't share any.

## 4. How to create a new libp2p transport
|
||||
|
||||
Today there are already several transports available and plenty to come, you can find these at [interface-transport implementations](https://github.com/libp2p/js-interfaces/tree/master/src/transport#modules-that-implement-the-interface) list.
|
||||
Today there are already 3 transports available, one in the works and plenty to come, you can find these at [interface-transport implementations](https://github.com/libp2p/interface-transport#modules-that-implement-the-interface) list.
|
||||
|
||||
Adding more transports is done through the same way as you added TCP and WebSockets. Some transports might offer extra functionalities, but as far as libp2p is concerned, if it follows the interface defined at the [spec](https://github.com/libp2p/js-interfaces/tree/master/src/transport#api) it will be able to use it.

|

|

If you decide to implement a transport yourself, please consider adding to the list so that others can use it as well.
