How do I get all messages on a channel and post to hastebin? discord.js

Question

I'm idealizing a doubt bot. In view of this, I must explain that at the end of the member's question, the channel must be closed and before that the bot must send a link from hastebin.com with the logs of the created channel.

An example in practice would be: I create the ticket, the channel is created so that only me and the staff can see the channel. I ask and am answered. After having my answer, the channel is closed (deleted). Before being deleted, the bot creates a log and sends it to the hastebin, which stays the same in the print below.

Please, help me!

edit: I know how to do most of them, but my problem is to get the channel log and post it in hastebin, formatted.

Answer 1

after we talk about we really got something here. I updated your code to something more efficiently and I think whatever people that uses discord.js will be able to understand what is going on here.

Old Code

    message.channel.fetchMessages().then(messages => {
        console.log(`${messages.size} procuradas.`);
        messages.array().reverse().forEach(msg => {
            console.log(`[${moment(msg.createdTimestamp).format("DD/MM/YYYY - hh:mm:ss a").replace("pm", "PM").replace("am", "AM")}] ` +
            `[${msg.author.username.toString()}]` + ": " + msg.content);
        });
        
    })

New Code

message.channel.fetchMessages().then(async messages => {
    console.log(`${messages.size} procuradas.`);

    let finalArray = [];

    const putInArray = async (data) => finalArray.push(data);
    const handleTime = (timestamp) => moment(timestamp).format("DD/MM/YYYY - hh:mm:ss a").replace("pm", "PM").replace("am", "AM"); 

    for (const message of messages.array().reverse()) await putInArray(`${handleTime(message.createdTimestamp)} ${message.author.username} : ${message.content}`); 

    console.log(finalArray);
    console.log(finalArray.length);

});

Hope it helps!

An update to the accepted answer: the Discord.js package has changed since the answer was written and the new way to fetch messages is with

message.channel.messages.fetch().then(...);
