Send message to specific channel with typescript

问题

I want to send a greeting message to an "welcome" text channel, whenever a new user joins the server (guild).

The problem I'm facing is that, when I find the wanted channel, I will receive the channel with the type GuildChannel.

Since GuildChannel has no send() function, I'm not able to send the message. But I can't find a way to find the TextChannel, so I'm stuck here.

How can I get to the TextChannel so that I'm able to use the send() message? Below the code I'm using by now:

// Get the log channel (change to your liking) 
const logChannel = guild.channels.find(123456); 
if (!logChannel) return;

// A real basic message with the information we need. 
logChannel.send('Hello there!'); // Property 'send' does not exist on type 'GuildChannel'

I'm using version 11.3.0 of discord.js

Thanks to this GitHub issue I've found the solution to my problem.

I need to use a Type Guard to narrow down the correct type.

My code now is this:

// Get the log channel
const logChannel = member.guild.channels.find(channel => channel.id == 123456);

if (!logChannel) return;

// Using a type guard to narrow down the correct type
if (!((logChannel): logChannel is TextChannel => logChannel.type === 'text')(logChannel)) return;

logChannel.send(`Hello there! ${member} joined the server.`);

I do this:

let channel = client.guilds.get('your-guild-id').channels.get('your-channel-id');
channel.send("it worked");

(client is the discord client). your code should work if you change find to get and put the channel id in some single quotes. Well, it works for me.

Maybe this can help you?

Code:

client.on('guildMemberAdd', member => {
    let channel = member.guild.channels.find('name', 'welcome');
    let memberavatar = member.user.avatarURL
        if (!channel) return;
        let embed = new Discord.RichEmbed()
            .setColor('RANDOM')
            .setThumbnail(memberavatar)
            .addField(':bust_in_silhouette: | name : ', `${member}`)
            .addField(':microphone2: | Welcome!', `Welcome to the server, ${member}`)
            .addField(':id: | User :', "**[" + `${member.id}` + "]**")
            .addField(':family_mwgb: | Your are the member', `${member.guild.memberCount}`)
            .addField("Name", `<@` + `${member.id}` + `>`, true)
            .addField('Server', `${member.guild.name}`, true )
            .setFooter(`**${member.guild.name}**`)
            .setTimestamp()
        channel.sendEmbed(embed);
});

Maybe for latecomers who are still looking for an answer this worked for me

let channel = client.channels.get("channelid") as Discord.TextChannel;
channel.send("what you want to send to that channel");
