Detect links in messages in Discord.js

Question

I'm new to discord.js. I'm trying to check if a message contains a link like "Hi, I'm from discord.gg/xxxxx and now I'll spam my link".
How can I check if the message contain the link?

Answer 1

I am unsure if you want to check for discord invite links specifically, or if you want to check for all links. Either way, you can use message.content.includes.

Example:

bot.on('message', (message) => { //whenever a message is sent
  if (message.content.includes('discord.gg/'||'discordapp.com/invite/')) { //if it contains an invite link
    message.delete() //delete the message
      .then(message.channel.send('Link Deleted:\n**Invite links are not permitted on this server**'))
  }
})

Answer 2

I find this is the best:

let regx = /^((?:https?:)?\/\/)?((?:www|m)\.)? ((?:discord\.gg|discordapp\.com))/g
let cdu = regx.test(message.content.toLowerCase().replace(/\s+/g, ''))

Tell me if it works!
