Discord.js ガイド

# v11からv12へのアップデート

長期間の開発の末、Discord.js v12は正式にリリースされました。つまり、v11から更新してボットで新しい機能を使うときです！しかし追加された新機能と同時に、v11向けに書かれたコードを壊すライブラリへの多くの変更があります。このガイドは、コードを更新するための便利なリファレンスとして機能し、変更された最もよく使用されるメソッドや、パーシャル、内部シャーディングなどの新しいトピックをカバーします。最後にメソッドとプロパティの変更の包括的なリストも含まれます。

# 始める前に

v12を使用するにはNode 12.x以降が必要です。最新の状態であることを確認してください。Nodeのバージョンを確認するには、ターミナルまたはコマンドプロンプトでnode -vを使用します。v12以降ではない場合は更新してください。使用しているOSごとにこれを手助けする情報がネット上に多くあります。

Nodeを最新にしたら、ターミナルまたはコマンドプロンプトでnpm install discord.jsを実行してテキストのみを使用するか、音声サポート用にnpm install discord.js @discordjs/opusを実行してv12をインストールできます。

インストールされたdiscord.jsのバージョンはnpm list discord.jsで確認できます。それでもv11.xが表示される場合はdiscord.jsを一度アンインストールし(npm uninstall discord.js)、再びインストールすることで、package.jsonの指定がメジャーバージョンの更新を妨げていないことを確認してください。詳しくはnpm documentationを参照してください。

# 変更されたよく使われるメソッド

  • すべての節の見出しには、Class#methodOrPropertyという規則に従って名前が付けられます。
  • 括弧の使用は、オプションを含むことを表します。例えばChannel#fetch(Pinned)Message(s)は、その節にChannel#fetchPinnedMessages、Channel#fetchMessages、およびChannel#fetchMessageの変更が含まれることを意味します。
  • アスタリスクはワイルドカードを示します。例えばChannel#send***は、このセクションにChannel#sendMessageやChannel#sendFile、Channel#sendEmbedなどの変更が含まれることを意味します。

# マネージャー/ キャッシュ

v12ではマネージャーという概念が導入されているため、Client#usersなどのデータ構造でCollection#getなどのコレクションメソッドを直接使用することはできなくなります。コレクションのメソッドを使用する前に、マネージャーでキャッシュを直接要求する必要があります。GuildMemberManager＃fetchやMessageManager#deleteなど、マネージャーで直接呼び出されるメソッドはAPIを呼び出します。

- client.users.get('123456789012345678');
+ client.users.cache.get('123456789012345678');

- channel.messages.get('123456789012345678');
+ channel.messages.cache.get('123456789012345678');

- guild.members.get('123456789012345678');
+ guild.members.cache.get('123456789012345678');

# Collection

# Collection#exists

collection.exists()は完全に削除されました。collection.some()を使用して、指定された値を満たす要素がコレクション内に存在するかどうかを確認する必要があります。

- client.users.exists('username', 'Bob');
+ client.users.cache.some(user => user.username === 'Bob');

# Collection#filterArray

collection.filterArray()は完全に削除されました。これは単なるcollection.filter().array()のヘルパーメソッドであり、ほとんどの場合、コレクションを配列に変換することは不要な操作です。

# Collection#find

collection.find('property', value)は完全に削除されました。v12のcollection.find()では関数のみを受け入れます。

- client.users.find('username', 'Bob');
+ client.users.cache.find(user => user.username === 'Bob');

# Collection#findAll

collection.findAll()は、collection.filterArray()の結果を複製するだけなので、完全に削除されました。

# Fetch

キャッシュされていないデータを取得する一部のメソッドが変更され、マネージャーを使用する形式に変更されました。

- client.fetchUser('123456789012345678');
+ client.users.fetch('123456789012345678');

- guild.fetchMember('123456789012345678');
+ guild.members.fetch('123456789012345678');

- guild.fetchMembers();
+ guild.members.fetch();

- textChannel.fetchMessage('123456789012345678');
+ textChannel.messages.fetch('123456789012345678');

- textChannel.fetchMessages({ limit: 10 });
+ textChannel.messages.fetch({ limit: 10 });

- textChannel.fetchPinnedMessages();
+ textChannel.messages.fetchPinned();

# Send

すべての.send***()メソッドは削除され、1つの一般的な.send()メソッドが採用されました。

- channel.sendMessage('Hey!');
+ channel.send('Hey!');

- channel.sendEmbed(embedVariable);
+ channel.send(embedVariable);
+ channel.send({ embed: embedVariable });

channel.send(embedVariable)は、その変数が MessageEmbedクラスのインスタンスである場合にのみ機能します。埋め込みデータがembedキー内にない限り、オブジェクトリテラルは期待した結果になりません。

- channel.sendCode('js', 'const version = 11;');
+ channel.send('const version = 12;', { code: 'js' });

- channel.sendFile('./file.png');
- channel.sendFiles(['./file-one.png', './file-two.png']);
+ channel.send({
    files: [{
        attachment: 'entire/path/to/file.jpg',
        name: 'file.jpg'
    }]
});
+ channel.send({
    files: ['https://cdn.discordapp.com/icons/222078108977594368/6e1019b3179d71046e463a75915e7244.png?size=2048']
});

# 役職

GuildMember.rolesコレクションはv12でマネージャーに変更されたため、メンバーの役職とやり取りするための多くの関連メソッドも変更されました。それらはもはやGuildMemberオブジェクトではなく、GuildMemberRoleManagerです。マネージャーは役職のAPIメソッドとキャッシュを、プレーンなコレクションであるGuildMemberRoleManager#cacheの形式で保持します。

- guildMember.addRole('123456789012345678');
- guildMember.addRoles(['123456789012345678', '098765432109876543']);
+ guildMember.roles.add('123456789012345678');
+ guildMember.roles.add(['123456789012345678', '098765432109876543']);

- guildMember.removeRole('123456789012345678');
- guildMember.removeRoles(['123456789012345678', '098765432109876543']);
+ guildMember.roles.remove('123456789012345678');
+ guildMember.roles.remove(['123456789012345678', '098765432109876543']);

- guildMember.setRoles(['123456789012345678', '098765432109876543']);
+ guildMember.roles.set(['123456789012345678', '098765432109876543']);

- guildMember.roles.get('123456789012345678');
+ guildMember.roles.cache.get('123456789012345678');

さらに、役職に関連するGuildMemberプロパティもGuildMemberRoleManagerに移動されました。

- guildMember.colorRole;
+ guildMember.roles.color;

- guildMember.highestRole;
+ guildMember.roles.highest;

- guildMember.hoistRole;
+ guildMember.roles.hoist;

# BANとBAN解除

メンバーとユーザーをBANするメソッドは、GuildMemberManagerに移動しました。

- guild.ban('123456789012345678');
+ guild.members.ban('123456789012345678');

- guild.unban('123456789012345678');
+ guild.members.unban('123456789012345678');

# 画像URL

user.avatarURLのような画像関連のプロパティはv12でメソッドになったため、それらに表示サイズを変えるなどのオプションを適用できます。

- user.avatarURL;
+ user.avatarURL();

- user.displayAvatarURL;
+ user.displayAvatarURL();

- guild.iconURL;
+ guild.iconURL();

- guild.splashURL;
+ guild.splashURL();

# 動的ファイルタイプ

バージョン12では、画像のファイルタイプを動的に設定できるようになりました。dynamicオプションが提供されている場合、画像がアニメーション化されているときは.gifのURLを受け取ります。それ以外の場合は、指定されたformatまたはデフォルトの.webpにフォールバックします。

user.avatarURL({ format: 'png', dynamic: true, size: 1024 });

# RichEmbedコンストラクター

RichEmbedコンストラクターが削除され、MessageEmbedコンストラクターが使用されるようになりました。使用方法はほとんど同じですが、違いはrichEmbed.attachFileとrichEmbed.addBlankFieldが削除され、代わりにmessageEmbed.addFieldsが追加されました。（messageEmbed.attachFilesはパラメーターとして単一のファイルも受け入れます）

# String Concatenation

v12 has changed how string concatenation works with stringifying objects. The

valueOf any data structure will return its id, which affects how it behaves in strings, eg. using an object for a mention. In v11, you used to be able to use channel.send(userObject + ' has joined!') and it would automatically stringify the object and it would become the mention (@user has joined!), but in v12, it will now send a message that says 123456789012345678 has joined instead. Using template literals (``) will still return the mention, however.

v12では、文字列連結がオブジェクトを文字列化する方法が変更されました。データ構造体のvalueOfはそのidを返します。これは、メンションにオブジェクトを使用するときなどの、文字列内での振る舞いに影響します。v11では、channel.send(userObject + ' has joined!')を使用して、オブジェクトを自動的に文字列化しメンションにできましたが(@user has joined!)、v12では123456789012345678 has joinedというメッセージを送信します。代わりにテンプレートリテラル(``)を使用するとメンションが返されます。

- channel.send(userObject + ' has joined!')
+ channel.send(`${userObject} has joined!`)

# ユーザーアカウント限定のメソッド

APIから一般公開されないため、すべてのユーザーアカウント限定のメソッドは削除されました。

# 音声

v12には安定性を向上させる新しい音声システムがありますが、オーディオの再生にいくつかの変更が加えられています。

# VoiceConnectionおよびVoiceBroadcastに適用
- connection.playFile('file.mp3')
+ connection.play('file.mp3')

- connection.playStream(stream)
+ connection.play(stream)

- connection.playArbitraryInput(input)
+ connection.play(input)

- connection.playBroadcast(broadcast)
+ connection.play(broadcast)

- connection.playOpusStream(stream)
+ connection.play(stream, { type: 'opus' })

- connection.playConvertedStream(stream)
+ connection.play(stream, { type: 'converted' })

また、v12でFFmpegを必要とせずに、Ogg OpusファイルまたはWebM Opusファイルを直接再生できるようになりました。

connection.play(fs.createReadStream('file.ogg'), { type: 'ogg/opus' });
connection.play(fs.createReadStream('file.webm'), { type: 'webm/opus' });

ストリームを再生するときに、plp、fec、bitrateの初期値を定義することもできます。マイナスビットレートは、不安定なネットワーク接続でオーディオを再生するときに役立つv12の新しい設定可能なオプションです。

- connection.playStream(stream).setBitrate(96)
+ connection.play(stream, { bitrate: 96 })

再生中にストリームの音量を変更する必要がない場合は、ボリュームを無効にしてパフォーマンスを改善できます。これは、再生中に元に戻すことはできません。

connection.play(stream, { volume: false });

v12の内部音声システムは、可能な限りストリームを使用するようになり、StreamDispatcher自体がWritableStreamになりました。また、新しい変更も含まれています。

- dispatcher.end()
+ dispatcher.destroy()

- dispatcher.on('end', handler)
+ dispatcher.on('finish', handler)

highWaterMarkオプション（デフォルトは12）を使用して、より安定した再生のためにオーディオを再生する前にキューに入れるオーディオパケットの数を手動で制御できます。

connection.play(stream, { highWaterMark: 512 });

オーディオストリームを頻繁に一時停止/再開する場合は、一時停止中に無音パケットの再生を有効にして、Discordクライアントでのノイズ(オーディオグリッチ)を防ぐことができます。

// trueを渡して”無音”を再生する
dispatcher.pause(true);

# ブロードキャスト

ブロードキャスト自体に、StreamDispatcherと同じのインターフェースを共有し、オーディオストリームの再生を制御するために使用できるBroadcastDispatcherが含まれるようになりました。

- client.createVoiceBroadcast()
+ client.voice.createBroadcast()

- broadcast.dispatchers
+ broadcast.subscribers

# 破壊的変更と削除

破壊的な変更の節の見出しは、v11のクラス/メソッド/プロパティにちなんで名前が付けられ、アルファベット順になっているため、探しているものを簡単に見つけることができます。追加の節ヘッダーには、現在の構文を適切に反映するために、v12クラス/メソッド/プロパティにちなんで名前が付けられます。

「差分」コードブロックは、古いメソッドと新しいメソッドを表示するために使用されます。赤は削除されたもので、緑はその代替です。一部には、処理されるバージョンが複数ある場合があります。反対に追加は、通常のJavaScript構文コードブロックが使用されます。

- user.presence.game
+ user.presence.activities

# GroupDMChannel

The GroupDMChannel class has been deprecated from the Discord API. While it's still available through Gamebridge for now, that will also be removed in the future. In addition, group DM's has always been unreliable and hacky to work with a bot.

# Guild

# Guild#acknowledge

guild.acknowledge() has been removed entirely, along with all other user account-only properties and methods.

# Guild#allowDMs

guild.allowDMs() has been removed entirely, along with all other user account-only properties and methods.

# Guild#ban

guild.ban() has been moved to the GuildMemberManager. In addition, the second parameter in guild.members.ban() has been changed. The options parameter no longer accepts a number, nor a string.

- guild.ban(user, 7);
+ guild.members.ban(user, { days: 7 });

- guild.ban(user, 'Too much trolling');
+ guild.members.ban(user, { reason: 'Too much trolling' });

# Guild#Channels

guild.channels is now a Manager instead of a Collection.

# Guild#createChannel

guild.createChannel() has been transformed in the shape of a Manager. The second, third and fourth parameters in guild.createChannel() have been changed/removed, leaving it with a total of two parameters, the second one being an object with all of the options available in ChannelData.

- guild.createChannel('new-channel', 'text', permissionOverwriteArray, 'New channel added for fun!');
+ guild.channels.create('new-channel', { type: 'text', permissionOverwrites: permissionOverwriteArray, reason: 'New channel added for fun!' });

# Guild#createEmoji

guild.createEmoji() has been transformed in the shape of a Manager. The third and fourth parameters in guild.createEmoji() have been changed/removed, leaving it with a total of three parameters. The roles and reason parameters from v11 have been merged into an object as the third parameter.

- guild.createEmoji('./path/to/file.png', 'NewEmoji', collectionOfRoles, 'New emoji added for fun!');
+ guild.emojis.create('./path/to/file.png', 'NewEmoji', { roles: collectionOfRoles, reason: 'New emoji added for fun!' });

# Guild#createRole

# Guild#defaultChannel

Unfortunately, "default" channels don't exist in Discord anymore, and as such, the guild.defaultChannel property has been removed with no alternative.

Q: "I previously had a welcome message system (or something similar) set up using that property. What can I do now?"

A: There are a few ways to tackle this. Using the example of a welcome message system, you can:

  1. Set up a database table to store the channel ID in a column when someone uses a !welcome-channel #channel-name command, for example. Then inside the guildMemberAdd event, use client.channels.cache.get('id') and send a message to that channel. This is the most reliable method and gives server staff freedom to rename the channel as they please.
  2. Make a new command that creates a welcome-messages channel, use guild.channels.cache.find(channel => channel.name === 'welcome-messages'), and send a message to that channel. This method will work fine in most cases, but will break if someone on that server decides to rename the channel. This may also give you unexpected results, due to Discord allowing multiple channels to have the same name.
