How to truncate a channel? - Chat

Truncate implies removing all messages from the channel. This will not delete the channel instead wipe out the messages from the channel.

This can be done from the client-side/server-side. I am using an admin user.

Steps in detail

Create and initialize the channel 

const channelID="live1"
const conversationlive = client.channel("livestream",channelID, {
 name: 'fourthlive',
 members: ['Seetha', 'Stephen'],
});

await conversationlive.create();

Send Message

const livemessage = await conversationlive.sendMessage({
text: 'Fourth livestream Helloo',
attachments: [
 {
  type: 'image',
  asset_url: 'https://bit.ly/2K74TaG',
  thumb_url: 'https://bit.ly/2Uumxti',
  myCustomField: 1
 }
],
 mentioned_users: ['Seetha'],
 anotherCustomField: 1
});

Query Channel 

const channel = client.channel("livestream", 'fourthlive' , {});
const lastMessageID = ''; 
const result = await channel.query({
 messages: { limit: 20, id_lt: lastMessageID},
 members: { limit: 20, offset: 0 },
 watchers: { limit: 20, offset: 0 }
});
console.log(result);
}
