A typeguard to check if the received message is from inside a guild.

I'm currently using the

@discordjs/core

@discordjs/core

package along with it's other subpackages and

discord-api-types

discord-api-types

for my bot.

Based off of the util functions from API Types. I wanted to check if the message is from a guild or not using a typeguard. Rather than checking if both

guild_id

guild_id

and

member

member

properties exist using if functions everytime.

After reading the docs. I realized the

guild_id

guild_id

property only exists when the message is from a guild. (obviously)
So I made this just like the

isGuildInteraction

isGuildInteraction

typeguard.

export type APIGuildMessage = GatewayMessageCreateDispatchData &
  Required<Pick<GatewayMessageCreateDispatchData, 'guild_id' | 'member'>>;

export function isGuildMessage(
  message: GatewayMessageCreateDispatchData
): message is APIGuildMessage {
  return Reflect.has(message, 'guild_id');
}

export type APIGuildMessage = GatewayMessageCreateDispatchData &
  Required<Pick<GatewayMessageCreateDispatchData, 'guild_id' | 'member'>>;

export function isGuildMessage(
  message: GatewayMessageCreateDispatchData
): message is APIGuildMessage {
  return Reflect.has(message, 'guild_id');
}

Idk if this actually exists and I missed it or if this is redundant in usage.
But I just thought it'd be nice. Any thoughts are welcome teri_smug

What's your exact discord.js

npm list discord.js

npm list discord.js

and node

node -v

node -v

version?

Ooooh yeah true... My mind actually skipped that part entirely.
Thanks for pointing that out teri_love

Then I think the best approach is to have and

Omitting the members property for webhook type and renaming the APIGuildMessage to APIGuildMemberMessage

Then creating a Guild message type which only has the guild id property available and others optional...
