 #### Configuring Transport Manager
 
-The Transport Manager is responsible for managing the libp2p transports life cycle. This includes starting listeners for the provided listen addresses, closing these listeners and dialing using the provided transports. By default, if a libp2p node has a list of multiaddrs for listening on and there are no valid transports for those multiaddrs, libp2p will throw an error on startup and shutdown. However, for some applications it is perfectly acceptable for libp2p nodes to start in dial only mode if all the listen multiaddrs failed. This error tolerance can be enabled as follows:

 Since this PeerInfo instances were navigating through the entire codebases, some data inconsistencies could be observed in libp2p. 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. Moreover, considering that several subsystems were modifying the peer data, libp2p had no way to determine the accurate data.

 There is one relevant aspect to consider with this change. When using a [`PeerId`](peer-id), the PeerStore **MUST** have known addresses for that peer in its AddressBook, so that it can perform the request. 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). When using a [`PeerInfo`](peer-info), the PeerStore was not required to have the multiaddrs when they existed on the PeerInfo instance.

-## 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`

-## 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/interfaces/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)

You should provide an array of public addresses in the libp2p `addresses.announce` option.

The simplest solution is to setup SSL with nginx and proxy to the node and setup a domain name for the certificate.

 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). 
+You can see this working on example [3.js](./3.js). The result should look like the following:
-
-As we've seen earlier, we can create our node with this createNode function.
-```js
-const createNode = async () => {
-  const node = await Libp2p.create({
-    addresses: {
-      listen: ['/ip4/0.0.0.0/tcp/0']

-      connEncryption: [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.multiaddrs)
-```
-
-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(msg.toString())
-      }
-    }
-  )
-})
-

-    stream,
-    async function (source) {
-      for await (const msg of source) {
-        console.log(msg.toString())
-      }
-    }
-  )
-})
-
-// Dialing node2 from node1
-const { stream: stream1 } = await node1.dialProtocol(node2.peerId, ['/node-2'])
-await pipe(
-  ['from 1 to 2'],
-  stream1
-)
-
-// Dialing node1 from node2
-const { stream: stream2 } = await node2.dialProtocol(node1.peerId, ['/node-1'])
-await pipe(
-  ['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 { stream: stream2 } = await node2.dialProtocol(node1.peerId, ['/node-1'])
-await pipe(
-  ['from 2 to 1'],
-  stream2
-)
-
-// Dialing from node1 to node2
-const { stream: stream1 } = await node1.dialProtocol(node2.peerId, ['/node-2'])
-await pipe(
-  ['from 1 to 2'],
-  stream1
-)

Some transports might offer extra functionalities, but as far as libp2p is concerned, if it follows the interface defined in 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.
 
 Hope this tutorial was useful. We are always looking to improve it, so contributions are welcome!
