How to send messages to the first channel on all Discord servers?

Question

Node.js

I want to do something like alerts for servers that have a bot. So that I can write one command to send a message to the server through the bot.

Answer 1

client.guilds.cache.array().forEach(guild => {
    guild.channels.cache
        .array()
        .filter(c => c.type !== "category" && c.type !== "voice" && c.position === 0)[0]
        .send("сообщение")
})

Don't forget two important things:

1. the first text channel on the server may have the setting "Prohibit server members from sending messages to the channel".
   will throw an error:
   

   UnhandledPromiseRejectionWarning: DiscordAPIError: Missing Permissions

   
   
2. the server may not have text channels.
   will throw a fatal error:
   

   TypeError: Cannot read property 'send' of undefined

   
   

make checks to avoid such cases.
