#BotKit is a #TypeScript framework for building #ActivityPub bots. The difference from typical Mastodon/Misskey bots? Your bot runs as its own independent server—no platform account needed.

This means no character limits, no rate limiting headaches, no API restrictions.

bot.onMention = async (session, message) => {
 await message.reply(text`Hi, ${message.actor}!`);
};

The ActivityPub stuff (federation, HTTP Signatures, delivery queues) is handled by #Fedify under the hood. You just write your bot logic.

Works with both #Deno and #Node.js.

BotKitは、ActivityPubボットを作るためのTypeScriptフレームワークです。既存のMastodon/Misskeyボットとの違いは、ボット自体が独立したサーバーとして動作すること。プラットフォームのアカウントは不要です。

文字数制限もなければ、APIレート制限に悩まされることもありません。

bot.onMention = async (session, message) => {
 await message.reply(text`こんにちは、${message.actor}さん！`);
};

フェデレーション、HTTP Signatures、配送キューといったActivityPub周りの処理はFedifyがすべて引き受けます。ボットのロジックを書くだけです。

DenoでもNode.jsでも動きます。

BotKit은 ActivityPub 봇을 만드는 #TypeScript 프레임워크입니다. 일반적인 Mastodon/Misskey 봇과 다른 점은, 봇 자체가 독립된 서버로 돌아간다는 겁니다. 플랫폼 계정이 필요 없습니다.

글자 수 제한도 없고, API 호출 제한에 시달릴 일도 없습니다.

bot.onMention = async (session, message) => {
 await message.reply(text`안녕하세요, ${message.actor}님!`);
};

연합(federation), HTTP Signatures, 메시지 전달 같은 #ActivityPub 관련 처리는 Fedify가 알아서 해줍니다. 봇 로직만 짜면 되는 거죠.

#Deno 및 #Node.js 둘 다 지원합니다.

#deno Question :
I have a fairly large process calculating all the osm admin levels to hierarchies by continent.

What makes "--max-heap-size" different from "--max-old-space-size" ?

When I had this, it allocated enough RAM for calculating but not for writing somehow …

Exciting news for #Fedify developers! We've just landed a major milestone for Fedify 2.0—the #CLI now runs natively on #Node.js and #Bun, not just #Deno (#456). If you install @fedify/cli@2.0.0-dev.1761 from npm, you'll get actual JavaScript that executes directly in your runtime, no more pre-compiled binaries from deno compile. This is part of our broader transition to Optique, a new cross-runtime CLI framework we've developed specifically for Fedify's needs (#374).

This change means a more natural development experience regardless of your #JavaScript runtime preference. Node.js developers can now run the CLI tools directly through their familiar ecosystem, and the same goes for Bun users. While Fedify 2.0 isn't released yet, we're excited to share this progress with the community—feel free to try out the dev version and let us know how it works for you!

Ha, someone ported my Node.js SQLite APIs to Deno https://docs.deno.com/api/node/sqlite/~/Session
