NodeJs:用ES6系统写导出

Question

我目前正在开发一个机器人，我用node.js编写

但是，我有一段代码:命令/server.js

const { SlashCommandBuilder } = require("discord.js");

module.exports = {
  data: new SlashCommandBuilder()
    .setName("server")
    .setDescription("Provides information about the server."),
  async execute(interaction) {
    // interaction.guild is the object representing the Guild in which the command was run
    await interaction.reply(
      `This server is ${interaction.guild.name} and has ${interaction.guild.memberCount} members.`
    );
  },
};

我在我的index.js里这样称呼它：

//for every command we have
for (const file of commandFiles) {
  //get the file path
  const filePath = path.join(commandsPath, file);
  //load our command_name.js
  const command = require(filePath);
  // Set a new item in the Collection with the key as the command name and the value as the exported module
  if ("data" in command && "execute" in command) {
    client.commands.set(command.data.name, command);
  } else {
    console.log(
      `[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`
    );
  }
}

当我将我的类型设置为模块时，在ES6语法中，什么是与server.js的等价的&&希望使用导入语法--所以我仍然得到数据并执行属性。

下面是如何使用server.js导入语法和导出语法编写ES6文件的示例：

// Import the `SlashCommandBuilder` class from the `discord.js` module
import { SlashCommandBuilder } from 'discord.js';

// Create an object with the data and execute properties
const command = {
  // Create a new instance of the `SlashCommandBuilder` class and set its name and description properties
  data: new SlashCommandBuilder()
    .setName('server')
    .setDescription('Provides information about the server.'),

  // Define the `execute` method, which takes an `interaction` object as its argument
  async execute(interaction) {
    // Use the `interaction.guild` property to get information about the Guild in which the command was run
    await interaction.reply(
      `This server is ${interaction.guild.name} and has ${interaction.guild.memberCount} members.`
    );
  },
};

// Export the `command` object
export default command;

然后，在index.js文件中，您可以使用导入语法导入命令对象，并对其进行重构以获取数据并执行属性：

// Import the `command` object from the `server.js` file
import command from './commands/server';

// Destructure the `data` and `execute` properties from the `command` object
const { data, execute } = command;

// Set a new item in the Collection with the key as the command name and the value as the exported module
if ("data" in command && "execute" in command) {
  client.commands.set(data.name, { data, execute });
} else {
  console.log(
    `[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`
  );
}
