Create thread in slash command execute

[ggrantrowberry]

I want to create a thread when I execute a slash command. This is probably really easy to do but I'm trying to follow the guide but I can't figure it out.

The guide says

const thread = await channel.threads.create({
	name: 'food-talk',
	autoArchiveDuration: 60,
	reason: 'Needed a separate thread for food',
});

I figured I could use the interaction object passed into the execute callback to get the channel and then create a thread. However the .threads property doesn't exist on it. I tried importing the client from my index.ts and fetching the channel by the id from the channelId property on the interaction object. But the .threads property didn't exist on that either.

How can I do this?

What error did you get, how is channel defined, what does it log as and what version of the library are you currently using npm list discord.js?

This is how I define the channel. Getting the correct channel is my issue.

export const Hello = {
    data: new SlashCommandBuilder()
        .setName('hello')
        .setDescription('say hello'),
    async execute(interaction: CommandInteraction<CacheType>) {
        const channel = await interaction.channel;
        

        await interaction.reply('Hello!');
    },
};

The error I get is from VS Code and Typescript telling me that

Property 'threads' does not exist on type 'TextBasedChannel'.
  Property 'threads' does not exist on type 'DMChannel'.

By default, the property channel of CommandInteraction is TextBasedChannel | null. The typedef TextBasedChannels includes the class DMChannel, that does not include the property threads.
You can easily avoid this by typing the channel like this:

const channel = interaction.channel as TextChannel;

Or check if the channel is typed as TextChannel before creating the thread, like this:

const channel = interaction.channel;

if (channel instanceof TextChannel) {
    channel.threads.create({
        name: 'food-talk',
        autoArchiveDuration: 60,
        reason: 'Needed a separate thread for food',
      });
} else {
      interaction.reply('This channel is not a text channel');
}

TextChannel is one of the TextBasedChannels and contain the property that you want, threads.
