feat: convert to typescript (#1172) 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
