Powercord snippet for adding and removing built in slash commands

slashcommand.md

Snippet

let { getModule, messages: { receiveMessage } } = require("powercord/webpack")
let { createBotMessage } = getModule(["createBotMessage"], false)


function CreateCommand(name, description, options, callback, applicationId="-1") {
    getModule(["getBuiltInCommands"], false).BUILT_IN_COMMANDS.push({
        applicationId: applicationId,
        description: description,
        displayDescription: description,
        displayName: name,
        execute: (args, context) => {
            let res = callback(args, context)
            if (res) {
                let msg = createBotMessage({channelId: context.channel.id, content: res.value})
                receiveMessage(context.channel.id, msg)
            }
        },
        id: `-${getModule(["getBuiltInCommands"], false).BUILT_IN_COMMANDS.length + 1}`,
        inputType: 0,
        name: name,
        options: options,
        type: 1,
    })
}

function RemoveCommand(name) {
    let cmds = getModule(["getBuiltInCommands"], false).BUILT_IN_COMMANDS
    cmds.pop(cmds.indexOf(cmds.find(i => i.name.toLowerCase() == name.toLowerCase())))
}

Adding a slash command

// syntax: (name, description, options[], callback)
CreateCommand("test", "test command", [{name: "test", displayName: "test", type: 3, required: true, description: "test", displayDescription: "test"}], (args, context) => {return {value: args[0].value}})

Removing a slash command

// syntax: (name)
RemoveCommand("test")

I've applied the suggested changes, thanks!

👍

cmds.pop(cmds.indexOf(cmds.find(i => i.name.toLowerCase() == name.toLowerCase())))

Array::pop doesn't take an index, try using Array::splice:

let cmdIndex = cmds.findIndex(i => i.name.toLowerCase() == name.toLowerCase())
if (cmdIndex >= 0) cmds.splice(cmdIndex, 1)
