Javascript 升级到 v14 时 Discord.js v13 代码中断

不一致js v14包含许多突破性的更改.现在需要使用Node 16.9或更高版本，因此请确保使用upgrade to the latest LTS version.

此版本的v14使用Discord API v10.

意图错误:

// v13
const client = new Client({
  intents: [
    Intents.FLAGS.GUILDS,
    Intents.FLAGS.GUILD_MESSAGES,
  ],
});

// OR
const client = new Client({
  intents: ['GUILDS', 'GUILD_MESSAGES'],
});

// v14
const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
  ],
});

Errors with interactions:

一些交互类型的防护装置已被拆除.您可以将interaction.type与InteractionType enum进行比较.

const { InteractionType } = require('discord.js');

// v13
if (interaction.isCommand()) {}
// v14
if (interaction.type === InteractionType.ApplicationCommand) {}

// v13
if (interaction.isAutocomplete()) {}
// v14
if (interaction.type === InteractionType.ApplicationCommandAutocomplete) {}

// v13
if (interaction.isMessageComponent()) {}
// v14
if (interaction.type === InteractionType.MessageComponent) {}

// v13
if (interaction.isModalSubmit()) {}
// v14
if (interaction.type === InteractionType.ModalSubmit) {}

通道错误:

一些通道型防护装置已拆除.要缩小通道，可以将channel.type与ChannelType enum进行比较.

const { ChannelType } = require('discord.js');
// v13
if (message.channel.isText()) {}
// v14
if (channel.type === ChannelType.GuildText) {}

// v13
if (message.channel.isVoice()) {}
// v14
if (channel.type === ChannelType.GuildVoice) {}

// v13
if (message.channel.isDM()) {}
// v14
if (channel.type === ChannelType.DM) {}

// v13
if (message.channel.isCategory()) {}
// v14
if (channel.type === ChannelType.GuildCategory) {}

对于ChannelType人的完整列表，您可以 Select read this answer人.

此外，还有一些新型防护装置:

channel.isDMBased();
channel.isTextBased();
channel.isVoiceBased();

生成器和嵌入错误:

MessageEmbed已重命名为EmbedBuilder.

// v13
const embed = new MessageEmbed();
// v14
const { EmbedBuilder } = require('discord.js');
const embed = new EmbedBuilder();

MessageComponents已重命名；它们不再有Message前缀，现在有Builder后缀.

// v13
const button = new MessageButton();
// v14 
const { ButtonBuilder } = require('discord.js');
const button = new ButtonBuilder();

// v13
const actionRow = new MessageActionRow();
// v14 
const { ActionRowBuilder } = require('discord.js');
const actionRow = new ActionRowBuilder();

// v13
const selectMenu = new MessageSelectMenu();
// v14
const { SelectMenuBuilder } = require('discord.js');
const selectMenu = new SelectMenuBuilder();

// v13
const textInput = new TextInputComponent();
// v14
const { TextInputBuilder } = require('discord.js');
const textInput = new TextInputBuilder();

枚举错误:

任何用于接受枚举参数的字符串或数字类型的区域现在只接受独占数字.

// Wrong
new ButtonBuilder()
  .setCustomId('verification')
  .setStyle('PRIMARY')

// Fixed
const { ButtonStyle } = require('discord.js');
new ButtonBuilder()
  .setCustomId('verification')
  .setStyle(ButtonStyle.Primary)

// Wrong
new TextInputBuilder()
  .setCustomId('verification')
  .setStyle('SHORT')

// Fixed
const { TextInputStyle } = require('discord.js');
new TextInputBuilder()
  .setCustomId('verification')
  .setStyle(TextInputStyle.Short)

活动类型错误:setPresence activity type in discord.js v14 can only be set to "PLAYING"
