 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.

 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.

-- A random walk approach can be used via `libp2p-kad-dht`, to crawl the network and find new peers along the way.

Different libp2p subsystems were running with different visions of the known peers data. For instance, a libp2p subsystem receives a copy of this instance with the peer multiaddrs and protocols, but if new data of the peer is obtained from other subsystem, it would not be updated on the former.

 There is one relevant aspect to consider with this change.

This was also true in the past, but it is important pointing it out because it might not be enough to switch from using [`PeerInfo`](peer-info) to [`PeerId`](peer-id).

+
+## ESM
+
+The biggest change to `libp2p@0.37.0` is that the module is now [ESM-only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
+
+ESM is the module system for JavaScript, it allows us to structure our code in separate files without polluting a global namespace.
+
+Other systems have tried to fill this gap, notably CommonJS, AMD, RequireJS and others, but ESM is [the official standard format](https://tc39.es/ecma262/#sec-modules) to package JavaScript code for reuse.
+
+## TypeScript
+
+The core `libp2p` module and all supporting modules have now been ported to TypeScript in a complete ground-up rewrite. This will not have a huge impact on most application code, but those that are type-aware, either by being written in TypeScript themselves or using JSDoc comments will notice full type completion and better error message when coding against the libp2p API.
+
+To reflect the updated nature of these modules, all ecosystem modules have been moved to the `@libp2p` org on npm, so `libp2p-tcp` has become `@libp2p/tcp`, `libp2p-mplex` has become `@libp2p/mplex` and so on. `@chainsafe/libp2p-noise` and `libp2p-gossipsub` are unaffected.
+
+## Config
+
+Because libp2p is now fully typed it was necessary to refactor the configuration object passed to the libp2p constructor. The reason being, it previously accepted config objects to pass to the constructors of the various modules - to type those we'd need to know the types of all possible modules in advance which isn't possible.
+
+The following changes have been made to the configuration object:
+
+1. It now takes instances of modules rather than their classes
+2. Keys from the `config` and `modules` objects have been migrated to the root of the object
+3. Use of the `enabled` flag has been removed - if you don't want a particular feature enabled, don't pass a module implementing that feature
+4. Some keys have been renamed = `transport` -> `transports`, `streamMuxer` -> `streamMuxers`, `connEncryption` -> `connectionEncryption`, etc
+5. Keys from `config.dialer` have been moved to `config.connectionManager` as the connection manager is now responsible for managing connections
+6. The `protocolPrefix` configuration option is now passed on a per-protocol basis for `identify`, `fetch` and `ping`
+
+**Before**
+
+```js
+import Libp2p from 'libp2p'
+import TCP from 'libp2p-tcp'

+    listen: ['/ip4/127.0.0.1/tcp/8000']
+  },
+  modules: {
+    transport: [
+      TCP
+    ],
+    streamMuxer: [
+      Mplex
+    ],
+    connEncryption: [
+      NOISE
+    ],
+    dht: KadDHT,

+  config: {
+    peerDiscovery: {
+      autoDial: true,
+      [MulticastDNS.tag]: {

+        enabled: true
+      }
+    },
+    dialer: {
+      dialTimeout: 60000
+    }
+  }
+})
+```
+
+**After**
+
+```js
+import { createLibp2p } from 'libp2p'

+    })
+  ],
+  identify: {
+    protocolPrefix: 'ipfs'
+  }
+})
+```
+
+## Bundled modules
+
+Previously you'd have to use deep import paths to get at bundled modules such as the private network module.
+
+Access to these modules is now controlled by the package.json export map so your import paths will need to be updated:
+
+**Before**
+
+```js
+import plaintext from 'libp2p/src/insecure/plaintext.js'
+import Protector from 'libp2p/src/pnet/index.js'
+import generateKey from 'libp2p/src/pnet/key-generator.js'
+import TransportManager from 'libp2p/src/transport-manager.js'
+```
+
+**After**
+
+```js
+import { Plaintext } from 'libp2p/insecure'
+import { PreSharedKeyConnectionProtector, generateKey } from 'libp2p/pnet'
+import { TransportManager } from 'libp2p/transport-manager'
+```
+
+## Events
+
+To reduce our dependency on Node.js internals, use of [EventEmitter](https://nodejs.org/api/events.html#class-eventemitter) has been replaced with the standard [EventTarget](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget).
+
+The EventTarget API is very similar to [HTML DOM Events](https://developer.mozilla.org/en-US/docs/Web/API/Event) used by the browser.
+
+All events are instances of the [CustomEvent](https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent) class. Event-specific information can be accessed via the `.detail` property of the passed event.
+
+They type of event emitted can be inferred from the types for each event emitter.
+
+**Before**
+
+```js
+const handler = (peerInfo) => {
+  //...
+}
+
+// listen for event
+libp2p.on('peer:discovery', handler)
+
+// stop listening for event
+libp2p.removeListener('peer:discovery', handler)
+libp2p.off('peer:discovery', handler)
+```
+
+**After**
+
+```js
+const handler = (event) => {
+  const peerInfo = event.detail
+  //...
+}
+
+// listen for event
+libp2p.addEventListener('peer:discovery', handler)
+
+// stop listening for event
+libp2p.removeEventListener('peer:discovery', handler)
+```
+
+## Pubsub
+
+Similar to the events refactor above, pubsub is now driven by the standard [EventTarget](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget) API.
+
+You can still subscribe to events without a listener with `.subscribe` but all other uses now use the standard API.
+
+Similar to the other events emitted by libp2p the event type is [CustomEvent](https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent). This is part of the js language but at the time of writing Node.js [does not support](https://github.com/nodejs/node/issues/40678) `CustomEvent`, so a polyfill is supplied as part of the `@libp2p/interfaces`
+
+**Before**
+
+```js
+const handler = (message: Message) => {
+  const topic = message.topic
+
+  //...
+}
+
+// listen for event
+libp2p.pubsub.subscribe('my-topic')
+libp2p.pubsub.on('my-topic', handler)
+
+// send event
+libp2p.pubsub.emit('my-topic', Uint8Array.from([0, 1, 2, 3]))
+
+// stop listening for event
+libp2p.unsubscribe('my-topic', handler)
+libp2p.pubsub.off('my-topic', handler)
+```
+
+**After**
+
+```js
+import type { Message } from '@libp2p/interface-pubsub'
+
+const handler = (event: CustomEvent<Message>) => {
+  const message = event.detail
+  const topic = message.topic
+
+  //...
+}
+
+// listen for event
+libp2p.pubsub.subscribe('my-topic')
+libp2p.pubsub.addEventListener('message', handler)
+
+// send event
+libp2p.pubsub.publish('my-topic', Uint8Array.from([0, 1, 2, 3]))
+
+// stop listening for event
+libp2p.pubsub.unsubscribe('my-topic')
+libp2p.pubsub.removeEventListener('message', handler)
+```

 # Delegated Routing with Libp2p and IPFS
 
-This example shows how to use delegated peer and content routing. The [Peer and Content Routing Example](../peer-and-content-routing) focuses
-on the DHT implementation. This example takes that a step further and introduces delegated routing. Delegated routing is
-especially useful when your libp2p node will have limited resources, making running a DHT impractical. It's
-also highly useful if your node is generating content, but can't reliably be on the network. You can use delegate nodes
-to provide content on your behalf.

It's also highly useful if your node is generating content, but can't reliably be on the network. You can use delegate nodes to provide content on your behalf.
 
 The starting [Libp2p Bundle](./src/libp2p-bundle.js) in this example starts by disabling the DHT and adding the Delegated Peer and Content Routers.

+Once you've completed the example, you should try enabled the DHT and see what kind of results you get! You can also enable the various Peer Discovery modules and see the impact it has on your Peer count.
 
 ## Prerequisite
-**NOTE**: This example is currently dependent on a clone of the [delegated routing support branch of go-ipfs](https://github.com/ipfs/go-ipfs/pull/4595).
+
+This example uses a publicly known delegated routing node. This aims to ease experimentation, but you should not rely on this in production.
 
 ## Running this example
 
 1. Install IPFS locally if you dont already have it. [Install Guide](https://docs.ipfs.io/introduction/install/)
 2. Run the IPFS daemon: `ipfs daemon`
-3. The daemon will output a line about its API address, like `API server listening on /ip4/127.0.0.1/tcp/8080`
-4. In another window output the addresses of the node: `ipfs id`. Make note of the websocket address, it will contain `/ws/` in the address.
-5. In `./src/libp2p-bundle.js` check if the host and port of your node are correct, according to the previous step. If they are different, replace them.
-6. In `./src/App.js` replace `BootstrapNode` with your nodes Websocket address from step 4.
-7. Start this example:

 ### Finding Content via the Delegate
 1. Add a file to your IPFS node. From this example root you can do `ipfs add ./README.md` to add the example readme.

 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.
-- 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).

 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.

 With the aid of both mechanisms, we can reuse an incomming connection to dial streams out too, this is specially useful when you are behind tricky NAT, firewalls or if you are running in a browser, where you can't have listening addrs, but you can dial out. By dialing out, you enable other peers to talk with you in Protocols that they want, simply by opening a new multiplexed stream.
 
-You can see this working on example [3.js](./3.js). The result should look like the following:
+You can see this working on example [3.js](./3.js).
+
+As we've seen earlier, we can create our node with this createNode function.
+```js
+const createNode = async () => {
+  const node = await createLibp2p({
+    addresses: {
+      listen: ['/ip4/0.0.0.0/tcp/0']
+    },
+    transports: [new TCP()],
+    streamMuxers: [new Mplex()],
+    connectionEncryption: [new Noise()],
+  })
+
+  await node.start()
+
+  return node
+}
+```
+
+We can now create our two nodes for this example.
+```js
+const [node1, node2] = await Promise.all([
+  createNode(),
+  createNode()
+])
+```
+
+Since, we want to connect these nodes `node1` & `node2`, we add our `node2` multiaddr in key-value pair in `node1` peer store.
+```js
+await node1.peerStore.addressBook.set(node2.peerId, node2.getMultiaddrs())
+```
+
+You may notice that we are only adding `node2` to `node1` peer store. This is because we want to dial up a bidirectional connection between these two nodes.
+
+Finally, let's create protocols for `node1` & `node2` and dial those protocols.
+```js
+node1.handle('/node-1', ({ stream }) => {
+  pipe(
+    stream,
+    async function (source) {
+      for await (const msg of source) {
+        console.log(uint8ArrayToString(msg.subarray()))
+      }
+    }
+  )
+})
+
+node2.handle('/node-2', ({ stream }) => {
+  pipe(
+    stream,
+    async function (source) {
+      for await (const msg of source) {
+        console.log(uint8ArrayToString(msg.subarray()))
+      }
+    }
+  )
+})
+
+// Dialing node2 from node1
+const stream1 = await node1.dialProtocol(node2.peerId, ['/node-2'])
+await pipe(
+  [uint8ArrayFromString('from 1 to 2')],
+  stream1
+)
+
+// Dialing node1 from node2
+const stream2 = await node2.dialProtocol(node1.peerId, ['/node-1'])
+await pipe(
+  [uint8ArrayFromString('from 2 to 1')],
+  stream2
+)
+```
+
+If we run this code, the result should look like the following:
 
 ```Bash
 > node 3.js
 from 1 to 2
 from 2 to 1
 ```
+
+So, we have successfully set up a bidirectional connection with protocol muxing. But you should be aware that we were able to dial from `node2` to `node1` even we haven't added the `node1` peerId to node2 address book is because we dialed node2 from node1 first. Then, we just dialed back our stream out from `node2` to `node1`. So, if we dial from `node2` to `node1` before dialing from `node1` to `node2` we will get an error.
+
+The code below will result into an error as `the dial address is not valid`.
+```js
+// Dialing from node2 to node1
+const stream2 = await node2.dialProtocol(node1.peerId, ['/node-1'])
+await pipe(
+  [uint8ArrayFromString('from 2 to 1')],
+  stream2
+)
+
+// Dialing from node1 to node2
+const stream1 = await node1.dialProtocol(node2.peerId, ['/node-2'])
+await pipe(
+  [uint8ArrayFromString('from 1 to 2')],
+  stream1
+)
+```

 You can change the pubsub `emitSelf` option if you want the publishing node to receive its own messages.
 
 ```JavaScript
-const defaults = {
-  config: {
-    pubsub: {
-      enabled: true,
-      emitSelf: true
-    }
-  }
-}

-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.
