## Connecting
``` ts
const client = new WAClient()
import { WAClient } from '@adiwajshing/baileys'
client.connect()
.then (([user, chats, contacts, unread]) => {
async function connectToWhatsApp () {
const client = new WAClient()
const [user, chats, contacts] = await client.connect ()
console.log ("oh hello " + user.name + " (" + user.id + ")")
console.log ("you have " + unread.length + " unread messages")
console.log ("you have " + chats.length + " chats")
})
.catch (err => console.log("unexpected error: " + err) )
// every chat object has a list of most recent messages
// can use that to retreive all your pending unread messages
// the 'count' property a chat object reflects the number of unread messages
// the 'count' property is -1 if the entire thread has been marked unread
const unread = chats.all().flatMap (chat => chat.messages.slice(chat.messages.length-chat.count))
console.log ("you have " + unread.length + " unread messages")
}
// run in main file
connectToWhatsApp ()
.catch (err => console.log("unexpected error: " + err) ) // catch any errors
```
If the connection is successful, you will see a QR code printed on your terminal screen, scan it with WhatsApp on your phone and you'll be logged in!
If you don't want to wait for WhatsApp to send all your chats while connecting, you can use the following function:
``` ts
const client = new WAClient()
client.connectSlim() // does not wait for chats & contacts
.then (user => {
import { WAClient } from '@adiwajshing/baileys'
async function connectToWhatsApp () {
const client = new WAClient()
const user = await client.connectSlim ()
console.log ("oh hello " + user.name + " (" + user.id + ")")
client.receiveChatsAndContacts () // wait for chats & contacts in the background
.then (([chats, contacts, unread]) => {
console.log ("you have " + unread.length + " unread messages")
console.log ("you have " + chats.length + " chats")
.then (([chats, contacts]) => {
console.log ("you have " + chats.all().length + " chats and " + contacts.length + " contacts")
})
})
.catch (err => console.log("unexpected error: " + err))
}
// run in main file
connectToWhatsApp ()
.catch (err => console.log("unexpected error: " + err) ) // catch any errors
```
Do note, the `chats` object returned is now a [KeyedDB](https://github.com/adiwajshing/keyed-db). This is done for the following reasons:
- Most applications require chats to be ordered in descending order of time. (`KeyedDB` does this in `log(N)` time)
- Most applications require pagination of chats (Use `chats.paginated()`)
- Most applications require **O(1)** access to chats via the chat ID. (Use `chats.get(jid)` with `KeyedDB`)
## Saving & Restoring Sessions
You obviously don't want to keep scanning the QR code every time you want to connect.
