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.

-#### 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 listenning 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:

 In `libp2p@0.27` we integrated the PeerStore (former [peer-book](https://github.com/libp2p/js-peer-book)) into the codebase. By that time, it was not documented in the [API DOC](../API.md) since it kept the same API as the `peer-book` and it was expected to be completelly rewritten in `libp2p@0.28`.
 
-Moving towards a separation of concerns regarding known peers' data, as well as enabling PeerStore persistence, the PeerStore is now divided into four main components: `AddressBook`, `ProtoBook`, `KeyBook` and `MetadataBook`. This resulted in API changes in the PeerStore, since each type of peer data should now be added in an atomic fashion.

 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

+
+## 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 { 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
+
+  //...
+}
+

 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 browser’s 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.

-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.

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