To prevent triggering keychain attack prevention on startup, refactor the `KeyChain` class to load the current PeerId as the `'self'` key on startup.
Fixes#1315
BREAKING CHANGE: the `loadKeychain` method has been removed as it is no longer necessary
Uses peer tag values to select low-value connections to prune when we have too many connections open.
BREAKING CHANGE: `connectionManager.peerValue` has been removed, use `peerStore.tagPeer` instead
* feat: limit protocol streams per-connection
Uses the `maxInboundStreams` and `maxOutboundStreams` of the `registrar.handle`
opts to limit the number of concurrent streams open on each connection
on a per-protocol basis.
Both values default to 1 so some tuning will be necessary to set
appropriate values for some protocols.
* chore: make error codes consistent
* chore: fix up examples
Adds a config option to specify a maximum message size we'll accept
for an Identify message.
The default is 8KB, the same as go-libp2p - previously we fell back
to the default `maxMessageLength` option of `it-length-prefixed`
which is 4MB.
Also adds a default timeout for reading responses to identify
requests which is used if an AbortSignal is not passed in.
The default timeout also aligns with go-libp2p.
There are a few places in the codebase where we send/receive data from the network without timeouts/abort controllers which means the user has to wait for the underlying socket to timeout which can take a long time depending on the platform, if at all.
This change ensures we can time out while running identify (both flavours), ping and fetch and adds tests to ensure there are no regressions.
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
* feat: add uPnP nat manager
Adds a really basic nat manager that attempts to use UPnP to punch
a hole through your router for any IPV4 tcp addresses you have
configured.
Adds any configured addresses to the node's observed addresses list
and adds observed addresses to `libp2p.multiaddrs` so we exchange
them with peers when performing `identify` and people can dial you.
Adds configuration options under `config.nat`
Hole punching is async to not affect start up time.
