## Reconnect Strategy
|
|
|
|
You can implement a custom reconnect strategy as a function:
|
|
|
|
- Receives the number of retries attempted so far.
|
|
- Returns `number | Error`:
|
|
- `number`: wait time in milliseconds prior to attempting a reconnect.
|
|
- `Error`: closes the client and flushes internal command queues.
|
|
|
|
## TLS
|
|
|
|
To enable TLS, set `socket.tls` to `true`. Below are some basic examples.
|
|
|
|
> For configuration options see [tls.connect](https://nodejs.org/api/tls.html#tlsconnectoptions-callback) and [tls.createSecureContext](https://nodejs.org/api/tls.html#tlscreatesecurecontextoptions), as those are the underlying functions used by this library.
|
|
|
|
### Create a SSL client
|
|
|
|
```typescript
|
|
createClient({
|
|
socket: {
|
|
tls: true,
|
|
ca: '...',
|
|
cert: '...'
|
|
}
|
|
});
|
|
```
|
|
|
|
### Create a SSL client using a self-signed certificate
|
|
|
|
```typescript
|
|
createClient({
|
|
socket: {
|
|
tls: true,
|
|
rejectUnauthorized: false,
|
|
cert: '...'
|
|
}
|
|
});
|
|
```
