Set gif avatar/banner to bot via discord.js

bot.ts

// discord developer dashboard doesnt yet allow uploading gif banners or avatars, so you need to do it via their api


// some gifs end up being "corrupted", as in they'll flicker black or look like they were shat out by a hellhound
// not sure yet why, maybe it's a filesize/dimensions kinda thing
const url = 'url.gif';
const banner = await axios.get(url, { responseType: 'arraybuffer' });
const base64 = Buffer.from(banner.data).toString('base64');
const base64Image = `data:image/gif;base64,${base64}`;

await this.client.rest.patch('/users/@me', {
    body: {
        avatar: base64Image,
        // banner: base64Image,
    }
});
