On join, bot gives pre determined role

Question

I have a command the gets the ID of a role and stores it (joinrole)

client.on('guildMemberAdd', (guildMember) => {
   guildMember.addRole(guildMember.guild.roles.find(role => role.name === "joinrole"));
});

how do I define the joinrole and make the bot give that specific role

Answer 1

The addRole method is deprecated and removed in Discord.js V12.x. So you should use the .add() method to add roles on guild members. This code should do it:

client.on('guildMemberAdd', (guildMember) => {
    const RoleToGiveNewMembers = guildMember.guild.roles.cache.get("RoleID");

    if(RoleToGiveNewMembers) {
        /**
         * Role found
         * We found a role to give to the user.
        */
       guildMember.roles.add(RoleToGiveNewMembers);
    }
});

There is also a nice guide for upgrading and using Discord.js V12. Updating from v11 to v12 .
