Utilities to make working with libp2p configuration simpler.

## Example - Load or create the "self" private key in a datastore

Most nodes will want to persist the same private key between restarts so this
function helps you extract one from a datastore if it exists, otherwise it
will create a new one and save it in the keystore.

The options you pass to this function should be the same as those passed to
the `@libp2p/keychain` service you configure your node with.

```TypeScript
import { loadOrCreateSelfKey } from '@libp2p/config'
import { keychain } from '@libp2p/keychain'
import { LevelDatastore } from 'datastore-level'
import { createLibp2p } from 'libp2p'

const datastore = new LevelDatastore('/path/to/db')
await datastore.open()

const keychainInit = {
 pass: 'yes-yes-very-secure'
}

const privateKey = await loadOrCreateSelfKey(datastore, keychainInit)

const node = await createLibp2p({
  privateKey,
  datastore,
  services: {
    keychain: keychain(keychainInit)
  }
})
```

# Install

```console
$ npm i @libp2p/config
```
