ようやくFedifyを触り始めた。WSL+DockerでNode.jsの環境をサクッと作って、コードはVSCodeで書けるようにした。後から環境設定が取っ散らからなくて良さそう。

Starting with 1.3.0, you can customize the User-Agent header for every HTTP request that Fedify makes.

https://unstable.fedify.dev/manual/federation#useragent

userAgent This API is available since Fedify 1.3.0. The options for making User-Agent header in the HTTP requests that Fedify makes. By default, it contains the name and version of the Fedify library, and the name and version of the JavaScript runtime, e.g.: Fedify/1.3.0 (Deno/2.0.4) Fedify/1.3.0 (Node.js/v22.10.0) Fedify/1.3.0 (Bun/1.1.33) You can customize the User-Agent header by providing options like software and url. For example, if you provide the following options: { software: "MyApp/1.0.0", url: "https://myinstance.com/" } The User-Agent header will be like: MyApp/1.0.0 (Fedify/1.3.0; Deno/2.0.4; +https://myinstance.com/) Or, you can rather provide a custom User-Agent string directly instead of an object for options.

Fedify: ActivityPub server framework

Have you heard of Val Town? Val Town is a kind of code pastebin + serverless function.

Actually, works just fine with Val Town. Here's a piece of ActivityPub software, implemented in about 170 lines of code, running on Val Town. Of course, it's built with Fedify!

Give it a follow @demo, and it will follow you back.

Curious to see how it was implemented? Check out the source code!

Fedify lookup 생각보다 유용해 보이긴 하는데

심심해서 포인트리스 fedify node -b로 출력해봤더니 파비콘 다 깨짐 ㅋㅋㅋㅋㅋㅋ
그리고 포인트리스 꽤 큰 인스턴스였구나

白背景が抜かれてしまっているが、一応弊インスタンスも(-b付きで)fetchできるようになった b付きじゃなくてもいけるように整えていくぞ
