数据类型的属性不存在

Question

I am new to TypeScript and I am having two problems with data types.

This is my code:

const say: object = {
  name: "say",
  aliases: [""],
  description: "",
  usage: "",
  run: (client: object, msg: object, args: string) => {
    if (!args[0]) return;
    msg.channel.send(args.join(" "));
  },
};

export default say;

The errors that come out are:

Property 'channel' does not exist on type 'object'.

Property 'join' does not exist on type 'string'.

I did a console.log (typeof msg) and console.log (typeof args) and indeed its data type is object and string .

I'm looking for an alternative to change the data type to any .

Answer 1

I assume that channel and message are discord.js types. So you can check discord.js types from here: https://github.com/discordjs/discord.js/tree/master/typings

and you can use Message type like this:

import {Message }from "discord.js"

in the second question. join is not a property for string. it's the property for arrays so probably args would be string[]

Answer 2

If you are sure about the type of msg, then you can create your own type.

interface Msg {
    channel: type here;
}
at the run, use this interface. (client: object, msg: Msg, args: string)

if you are not sure about its structure, then just say 'msg' there without any typedef.

do you mean args: string[] . It doesn't make sense to apply a join on a string here.
