Addresses PR comments from #1172 - fixes syntax of examples in docs, adds the transport manager to the exports map and renames fault tolerance enum for consistency.
Converts this module to typescript.
- Ecosystem modules renamed from (e.g.) `libp2p-tcp` to `@libp2p/tcp`
- Ecosystem module now have named exports
- Configuration has been updated, now pass instances of modules instead of classes:
- Some configuration keys have been renamed to make them more descriptive. `transport` -> `transports`, `connEncryption` -> `connectionEncryption`. In general where we pass multiple things, the key is now plural, e.g. `streamMuxer` -> `streamMuxers`, `contentRouting` -> `contentRouters`, etc. Where we are configuring a singleton the config key is singular, e.g. `connProtector` -> `connectionProtector` etc.
- Properties of the `modules` config key have been moved to the root
- Properties of the `config` config key have been moved to the root
```js
// before
import Libp2p from 'libp2p'
import TCP from 'libp2p-tcp'
await Libp2p.create({
modules: {
transport: [
TCP
],
}
config: {
transport: {
[TCP.tag]: {
foo: 'bar'
}
},
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
}
})
```
```js
// after
import { createLibp2p } from 'libp2p'
import { TCP } from '@libp2p/tcp'
await createLibp2p({
transports: [
new TCP({ foo: 'bar' })
],
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
})
```
- Use of `enabled` flag has been reduced - previously you could pass a module but disable it with config. Now if you don't want a feature, just don't pass an implementation. Eg:
```js
// before
await Libp2p.create({
modules: {
transport: [
TCP
],
pubsub: Gossipsub
},
config: {
pubsub: {
enabled: false
}
}
})
```
```js
// after
await createLibp2p({
transports: [
new TCP()
]
})
```
- `.multiaddrs` renamed to `.getMultiaddrs()` because it's not a property accessor, work is done by that method to calculate announce addresses, observed addresses, etc
- `/p2p/${peerId}` is now appended to all addresses returned by `.getMultiaddrs()` so they can be used opaquely (every consumer has to append the peer ID to the address to actually use it otherwise). If you need low-level unadulterated addresses, call methods on the address manager.
BREAKING CHANGE: types are no longer hand crafted, this module is now ESM only
We have a peerstore that keeps all data for all observed peers in memory with no eviction.
This is fine when you don't discover many peers but when using the DHT you encounter a significant number of peers so our peer storage grows and grows over time.
We have a persistent peer store, but it just periodically writes peers into the datastore to be read at startup, still keeping them in memory.
It also means a restart doesn't give you any temporary reprieve from the memory leak as the previously observed peer data is read into memory at startup.
This change refactors the peerstore to use a datastore by default, reading and writing peer info as it arrives. It can be configured with a MemoryDatastore if desired.
It was necessary to change the peerstore and *book interfaces to be asynchronous since the datastore api is asynchronous.
BREAKING CHANGE: `libp2p.handle`, `libp2p.registrar.register` and the peerstore methods have become async
Looks like this project stopped running the `test:node` npm script when it was migrated to gh actions.
Re-enable it and fix all the related test failures.
BREAKING CHANGES:
top level types were updated, multiaddr@9.0.0 is used, dialer and keychain internal property names changed and connectionManager minPeers is not supported anymore
* feat: auto relay
* fix: leverage protoBook events to ask relay peers if they support hop
* chore: refactor disconnect
* chore: do not listen on a relayed conn
* chore: tweaks
* chore: improve _listenOnAvailableHopRelays logic
* chore: default value of 1 to maxListeners on auto-relay
BREAKING CHANGE: all API methods with peer-info parameters or return values were changed. You can check the API.md document, in order to check the new values to use
* refactor: add dialing over relay support
* chore: fix lint
* fix: dont clear listeners on close
* fix: if dial errors already have codes, just rethrow them
* fix: clear the registrar when libp2p stops
* fix: improve connection maintenance with circuit
* chore: correct feedback
* test: use chai as promised
* test(fix): reset multiaddrs on dial test
* 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
