be8fc9daf1 fix: stop stream after first pong received (#545)

the ping protocol is never closed.

The change here uses `take` to only receive one buffer from the
remote node before closing the stream.

440fbf0c04 refactor(async): update transports subsystem (#461)
* test: remove all tests for a clean slate

The refactor will require a large number of updates to the tests. In order
to ensure we have done a decent deduplication, and have a cleaner suite of tests
we've removed all tests. This will also allow us to more easily see tests
for the refactored systems.

We have a record of the latest test suites in master, so we are not losing any history.

* chore: update tcp and websockets
* chore: remove other transports until they are converted
* chore: use mafmt and multiaddr async versions
* chore: add and fix dependencies
* chore: clean up travis file
* feat: add new transport manager
* docs: add constructor jsdocs
* refactor(config): check that transports exist
This also removes the other logic, it can be added when those subsystems are refactored

* chore(deps): use async peer-id and peer-info
* feat: wire up the transport manager with libp2p
* chore: remove superstruct dep

## 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.
`libp2p.on('peer:disconnect', (peer) => {})`

## 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><summary>Read More</summary>
If you want to know more about libp2p transports, you should read the following content:
- https://docs.libp2p.io/concepts/transport
- https://github.com/libp2p/specs/tree/master/connections
</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><summary>Read More</summary>
If you want to know more about libp2p connection encryption, you should read the following content:
- https://docs.libp2p.io/concepts/secure-comms
- https://github.com/libp2p/specs/tree/master/connections
</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]
}
})
```

- https://github.com/libp2p/specs/tree/master/connections
- https://github.com/libp2p/specs/tree/master/mplex
</details>
#### 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',

]
const node = await Libp2p.create({
modules: {
transport: [WebSockets],
connEncryption: [SECIO],
streamMuxer: [MPLEX],
peerDiscovery: [Bootstrap]
},
config: {
peerDiscovery: {
autoDial: true, // Auto connect to discovered peers (limited by ConnectionManager minPeers)
// The `tag` property will be searched when creating the instance of your Peer Discovery service.
// The associated object, will be passed to the service when it is instantiated.
[Bootstrap.tag]: {
enabled: true,
list: bootstrapMultiaddrs // provide array of multiaddrs
}
}
}
})
node.on('peer:discovery', (peer) => {
console.log('Discovered %s', peer.id.toB58String()) // Log discovered peer
})
node.on('peer:connect', (peer) => {
console.log('Connected to %s', peer.id.toB58String()) // Log connected peer
})
// start libp2p
await node.start()

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

- [Pubsub](#pubsub)
- [Getting subscribers](#getting-subscribers)
- [Getting subscribed topics](#getting-subscribed-topics)
## 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)
```

For this demo, we will connect to IPFS default bootstrapper nodes and so, we will need to support the same set of features those nodes have, that are: TCP, mplex and SECIO. You can see the complete example at [1.js](./1.js).

## 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 bundle to include MulticastDNS.
Update your libp2p configuration to include MulticastDNS.
```JavaScript
class MyBundle extends libp2p {
constructor (peerInfo) {
const defaults = {
modules: {
transport: [ TCP ],
streamMuxer: [ Mplex ],
connEncryption: [ SECIO ],
peerDiscovery: [ MulticastDNS ]
},
config: {
peerDiscovery: {
mdns: {
// Run at 1s so we can observe more quickly, default is 10s
interval: 1000,
enabled: true
}
const Libp2p = require('libp2p')
const MulticastDNS = require('libp2p-mdns')
const createNode = () => {
return Libp2p.create({
modules: {
transport: [ TCP ],
streamMuxer: [ Mplex ],
connEncryption: [ SECIO ],
peerDiscovery: [ MulticastDNS ]
},
config: {
peerDiscovery: {
mdns: {
interval: 20e3,
enabled: true
}
}
}
super(defaultsDeep(_options, defaults))
}
})
}
```
To observe it working, spawn two nodes.
```JavaScript
parallel([
(cb) => createNode(cb),
(cb) => createNode(cb)
], (err, nodes) => {
if (err) { throw err }
const [node1, node2] = await Promise.all([
createNode(),
createNode()
])
const node1 = nodes[0]
const node2 = nodes[1]
node1.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
node2.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
})
node1.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
node2.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
```
If you run this example, you will see a continuous stream of each peer discovering each other.
If you run this example, you will see the other peers being discovered.

# libp2p running in the Browser
# libp2p in the browser
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.
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.
# 1. Setting up a simple app that lists connections to other nodes
## Setup
Start by installing libp2p's dependencies.
In order to run the example, first install the dependencies from same directory as this README:
```bash
> cd ../../
> npm install
> cd examples/libp2p-in-the-browser
```
cd ./examples/libp2p-in-the-browser
npm install
```
Then simply go into the folder [1](./1) and execute the following
## Signaling Server
```bash
> cd 1
> npm install
> npm start
# open your browser in port :9090
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
```
## 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 create your custom match functions.
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

# 2. Reuse existing connection
The example 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.

Currently, we have two available [libp2p-spdy](https://github.com/libp2p/js-libp2p-spdy) and [libp2p-mplex](https://github.com/libp2p/js-libp2p-mplex) and pluging them in is as easy as adding another transport. Let's revisit our libp2p bundle.

# [Transports](http://libp2p.io/implementations/#transports)
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/interface-transport) specification. Some examples of possible transports are: TCP, UTP, WebRTC, QUIC, HTTP, Pigeon and so on.

Now that we have our `createNode` function, 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 pull-stream
> npm install it-pipe it-buffer
```
And we also need to import the module on our .js file:
```js
const pull = require('pull-stream')
const pipe = require('it-pipe')
const { toBuffer } = require('it-buffer')
```
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.

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')

```js
parallel([
(cb) => createNode(cb),
(cb) => createNode(cb)

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/interface-transport#api) it will be able to use it.
