`fedify`: CLI toolchain

The fedify command is a CLI toolchain for Fedify and debugging ActivityPub-enabled federated server apps. Although it is primarily designed for developers who use Fedify, it can be used with any ActivityPub-enabled server.

Installation

Using npm

If you have Node.js or Bun installed, you can install fedify by running the following command:

Node.jsBun

npm install -g @fedify/cli

bun install -g @fedify/cli

Using Deno

If you have Deno installed, you can install fedify by running the following command:

Linux/macOSWindows

deno install \
  -g \
  -A \
  --unstable-fs --unstable-kv --unstable-temporal \
  -n fedify \
  jsr:@fedify/cli

powershell

deno install `
  -g `
  -A `
  --unstable-fs --unstable-kv --unstable-temporal `
  -n fedify `
  jsr:@fedify/cli

Downloading the executable

You can download the pre-built executables from the releases page. Download the appropriate executable for your platform and put it in your PATH.

`fedify init`: Initializing a Fedify project

This command is available since Fedify 0.12.0.

The fedify init command is used to initialize a new Fedify project. It creates a new directory with the necessary files and directories for a Fedify project. To create a new Fedify project, run the below command:

fedify init my-fedify-project

The above command will start the interactive prompt to initialize a new Fedify project. It will ask you a few questions to set up the project:

JavaScript runtime: Deno, Bun, or Node.js
Package manager (if Node.js): npm, pnpm, or Yarn
Web framework: Bare-bones, Fresh (if Deno), Hono, Express (unless Deno), or Nitro (unless Deno)
Key-value store: In-memory, Redis, PostgreSQL, or Deno KV (if Deno)
Message queue: In-memory, Redis, PostgreSQL, AMQP (e.g., RabbitMQ), or Deno KV (if Deno)

Alternatively, you can specify the options in the command line to skip some of interactive prompts:

`-r`/`--runtime`: JavaScript runtime

You can specify the JavaScript runtime by using the -r/--runtime option. The available options are:

deno: Deno
bun: Bun
node: Node.js

`-p`/`--package-manager`: Node.js package manager

If you choose Node.js as the JavaScript runtime, you can specify the package manager by using the -p/--package-manager option. The available options are:

npm: npm
pnpm: pnpm
yarn: Yarn

It's ignored if you choose Deno or Bun as the JavaScript runtime.

`-w`/`--web-framework`: Web framework

You can specify the web framework to integrate with Fedify by using the -w/--web-framework option. The available options are:

fresh: Fresh (if Deno)
hono: Hono
express: Express (unless Deno)
nitro: Nitro (unless Deno)

If it's omitted, no web framework will be integrated.

`-k`/`--kv-store`: Key-value store

You can specify the key-value store to use by using the -k/--kv-store option. The available options are:

redis: Redis
postgres: PostgreSQL
denokv: Deno KV (if Deno)

If it's omitted, the in-memory key-value store (which is for development purpose) will be used.

`-q`/`--message-queue`: Message queue

You can specify the message queue to use by using the -q/--message-queue option. The available options are:

redis: Redis
postgres: PostgreSQL
amqp: AMQP (e.g., RabbitMQ)
denokv: Deno KV (if Deno)

If it's omitted, the in-process message queue (which is for development purpose) will be used.

`fedify lookup`: Looking up an ActivityPub object

The fedify lookup command is used to look up an ActivityPub object by its URL or an actor by its handle.

For example, the below command looks up a Note object with the given URL:

fedify lookup https://todon.eu/@hongminhee/112341925069749583

The output will be like the below:

Note {
  id: URL "https://todon.eu/users/hongminhee/statuses/112341925069749583",
  attachments: [
    Document {
      name: "The demo video on my terminal",
      url: URL "https://todon.eu/system/media_attachments/files/112/341/916/300/016/369/original/f83659866f94054f.mp"... 1 more character,
      mediaType: "video/mp4"
    }
  ],

  sensitive: false
}

Looking up an actor by handle

You can also look up an actor by its handle or URL. For example, the below command looks up an actor with the given handle:

fedify lookup @fedify-example@fedify-blog.deno.dev

The output will be like the below:

Person {
  id: URL "https://fedify-blog.deno.dev/users/fedify-example",
  name: "Fedify Example Blog",
  published: 2024-03-03T13:18:11.857384756Z,
  summary: "This blog is powered by Fedify, a fediverse server framework.",
  url: URL "https://fedify-blog.deno.dev/",
  preferredUsername: "fedify-example",
  publicKey: CryptographicKey {
    id: URL "https://fedify-blog.deno.dev/users/fedify-example#main-key",
    owner: URL "https://fedify-blog.deno.dev/users/fedify-example",
    publicKey: CryptoKey {
      type: "public",
      extractable: true,
      algorithm: {
        name: "RSASSA-PKCS1-v1_5",
        modulusLength: 4096,
        publicExponent: Uint8Array(3) [ 1, 0, 1 ],
        hash: { name: "SHA-256" }
      },
      usages: [ "verify" ]
    }
  },
  inbox: URL "https://fedify-blog.deno.dev/users/fedify-example/inbox",
  outbox: URL "https://fedify-blog.deno.dev/users/fedify-example/outbox",
  following: URL "https://fedify-blog.deno.dev/users/fedify-example/following",
  followers: URL "https://fedify-blog.deno.dev/users/fedify-example/followers",
  endpoints: Endpoints { sharedInbox: URL "https://fedify-blog.deno.dev/inbox" },
  discoverable: true,
  suspended: false,
  memorial: false,
  indexable: true
}

You can omit the @ prefix when looking up an actor by handle:

fedify lookup fedify-example@fedify-blog.deno.dev

Or you can look up an actor by acct: URL:

fedify lookup acct:fedify-example@fedify-blog.deno.dev

Looking up multiple objects at once

You can also look up multiple objects at once by specifying multiple URLs or handles. For example, the below command looks up multiple objects:

fedify lookup @hongminhee@fosstodon.org @fedify@hollo.social

The output will be like the below:

Person {
  ...
}
----
Person {
  ...
}

As you can see, the outputs are separated by ---- by default. You can change the separator by using the -s/--separator option.

`-c`/`--compact`: Compact JSON-LD

NOTE

This option is mutually exclusive with -e/--expanded and -r/--raw.

You can also output the object in the compacted JSON-LD format by using the -c/--compact option:

fedify lookup --compact https://todon.eu/@hongminhee/112341925069749583

The output will be like the below:

`-e`/`--expanded`: Expanded JSON-LD

NOTE

This option is mutually exclusive with -c/--compact and -r/--raw.

You can also output the object in the expanded JSON-LD format by using the -e/--expanded option:

fedify lookup --expand https://todon.eu/@hongminhee/112341925069749583

The output will be like the below:

`-r`/`--raw`: Raw JSON

This option is available since Fedify 0.15.0.

NOTE

This option is mutually exclusive with -c/--compact and -e/--expanded.

You can also output the fetched object in the raw JSON format by using the -r/--raw option:

fedify lookup --raw https://todon.eu/@hongminhee/112341925069749583

The output will be like the below:

      ]
    }
  }
}

`-a`/`--authorized-fetch`: Authorized fetch

You can also use the -a/--authorized-fetch option to fetch the object with authentication. Under the hood, this option generates an one-time key pair, spins up a temporary ActivityPub server to serve the public key, and signs the request with the private key.

Here's an example where the fedify lookup fails due to the object being protected:

fedify lookup @tchambers@indieweb.social

The above command will output the below error:

Failed to fetch the object.
It may be a private object.  Try with -a/--authorized-fetch.

However, you can fetch the object with the -a/--authorized-fetch option:

fedify lookup --authorized-fetch @tchambers@indieweb.social

This time, the above command will output the object successfully:

`-u`/`--user-agent`: Custom `User-Agent` header

This option is available since Fedify 1.3.0.

By default, the fedify lookup command sends the User-Agent header with the value Fedify/1.3.0 (Deno/2.0.4) (version numbers may vary). You can specify a custom User-Agent header by using the -u/--user-agent option. For example, to send the User-Agent header with the value MyApp/1.0, run the below command:

fedify lookup --user-agent MyApp/1.0 @fedify@hollo.social

`-s`/`--separator`: Output separator

This option is available since Fedify 1.3.0.

You can specify the separator between the outputs when looking up multiple objects at once by using the -s/--separator option. For example, to use the separator ==== between the outputs, run the below command:

fedify lookup -s ==== @fedify@hollo.social @hongminhee@fosstodon.org

It does not affect the output when looking up a single object.

`fedify inbox`: Ephemeral inbox server

The fedify inbox command is used to spin up an ephemeral server that serves the ActivityPub inbox with an one-time actor, through a short-lived public DNS with HTTPS. This is useful when you want to test and debug the outgoing activities of your server. To start an ephemeral inbox server, run the below command:

fedify inbox

If it goes well, you will see the output like the below (without termination; press ^C to stop the server):

✔ The ephemeral ActivityPub server is up and running: https://12a4fea81cbcf6.lhr.life/
✔ Followed @bibelus_vasariol@activitypub.academy
╭───────────────┬─────────────────────────────────────────╮
│ Actor handle: │ i@12a4fea81cbcf6.lhr.life               │
├───────────────┼─────────────────────────────────────────┤
│    Actor URI: │ https://12a4fea81cbcf6.lhr.life/i       │
├───────────────┼─────────────────────────────────────────┤
│  Actor inbox: │ https://12a4fea81cbcf6.lhr.life/i/inbox │
├───────────────┼─────────────────────────────────────────┤
│ Shared inbox: │ https://12a4fea81cbcf6.lhr.life/inbox   │
╰───────────────┴─────────────────────────────────────────╯

Although the given URIs and handle are short-lived, they are anyway publicly dereferenceable until the server is terminated. You can use these URIs and handle to test and debug the outgoing activities of your server.

If any incoming activities are received, the server will log them to the console:

╭────────────────┬────────────────────────────────────╮
│     Request #: │ 3                                  │
├────────────────┼────────────────────────────────────┤
│ Activity type: │ Create                             │
├────────────────┼────────────────────────────────────┤
│  HTTP request: │ POST /inbox                        │
├────────────────┼────────────────────────────────────┤
│ HTTP response: │ 202                                │
├────────────────┼────────────────────────────────────┤
│        Details │ http://12a4fea81cbcf6.lhr.life/r/3 │
╰────────────────┴────────────────────────────────────╯

You can also see the details of the incoming activities by visiting the /r/:id endpoint of the server in your browser:

The details of the incoming activities

`-f`/`--follow`: Follow an actor

The -f/--follow option is used to follow an actor. You can specify the actor handle or URI to follow. For example, to follow the actor with the handle @john@doe.com and @jane@doe.com, run the below command:

fedify inbox -f @john@doe.com -f @jane@doe.com

NOTE

Although -f/--follow option sends Follow activities to the specified actors, it does not guarantee that they will accept the follow requests. If the actors accept the follow requests, you will receive the Accept activities in the inbox server, and the server will log them to the console:

╭────────────────┬─────────────────────────────────────╮
│     Request #: │ 0                                   │
├────────────────┼─────────────────────────────────────┤
│ Activity type: │ Accept                              │
├────────────────┼─────────────────────────────────────┤
│  HTTP request: │ POST /i/inbox                       │
├────────────────┼─────────────────────────────────────┤
│ HTTP response: │ 202                                 │
├────────────────┼─────────────────────────────────────┤
│        Details │ https://876f71397f5c31.lhr.life/r/0 │
╰────────────────┴─────────────────────────────────────╯

`-a`/`--accept-follow`: Accept follow requests

The -a/--accept-follow option is used to accept follow requests from actors. You can specify the actor handle or URI to accept follow requests. Or you can accept all follow requests by specifying the wildcard *. For example, to accept follow requests from the actor with the handle @john@doe.com and @jane@doe.com, run the below command:

fedify inbox -a @john@doe.com -a @jane@doe.com

When the follow requests are received from the specified actors, the server will immediately send the Accept activities to them. Otherwise, the server will just log the Follow activities to the console without sending the Accept activities.

`-T`/`--no-tunnel`: Local server without tunneling

The -T/--no-tunnel option is used to disable the tunneling feature of the inbox server. By default, the inbox server tunnels the local server to the public internet, so that the server is accessible from the outside. If you want to disable the tunneling feature, run the below command:

fedify inbox --no-tunnel

It would be useful when you want to test the server locally but are worried about the security implications of exposing the server to the public internet.

NOTE

If you disable the tunneling feature, the ephemeral ActivityPub instance will be served via HTTP instead of HTTPS.

`fedify node`: Visualizing an instance's NodeInfo

This command is available since Fedify 1.2.0.

The result of fedify lookup fosstodon.org. The NodeInfo document is
visualized along with the favicon.

The fedify node command fetches the given instance's NodeInfo document and visualizes it in neofetch-style. The argument can be either a bare hostname or a full URL.

TIP

Not all instances provide the NodeInfo document. If the given instance does not provide the NodeInfo document, the command will output an error message.

`-b`/`--best-effort`: Parsing with best effort

The -b/--best-effort option is used to parse the NodeInfo document with best effort. If the NodeInfo document is not well-formed, the option will try to parse it as much as possible.

`--no-favicon`: Disabling favicon fetching

The --no-favicon option is used to disable fetching the favicon of the instance.

`-m`/`--metadata`: Showing metadata

The -m/--metadata option is used to show the extra metadata of the NodeInfo, i.e., the metadata field of the document.

`-u`/`--user-agent`: Custom `User-Agent` header

This option is available since Fedify 1.3.0.

By default, the fedify node command sends the User-Agent header with the value Fedify/1.3.0 (Deno/2.0.4) (version numbers may vary). You can specify a custom User-Agent header by using the -u/--user-agent option. For example, to send the User-Agent header with the value MyApp/1.0, run the below command:

fedify node --user-agent MyApp/1.0 mastodon.social

`fedify tunnel`: Exposing a local HTTP server to the public internet

This command is available since Fedify 0.13.0.

The fedify tunnel command is used to expose a local HTTP server to the public internet using a secure tunnel. It is useful when you want to test your local ActivityPub server with the real-world ActivityPub instances.

To create a tunnel for a local server, for example, running on port 3000, run the below command:

fedify tunnel 3000

TIP

The HTTP requests through the tunnel have the following headers:

X-Forwarded-For: The IP address of the client.
X-Forwarded-Proto: The protocol of the client, either http or https.
X-Forwarded-Host: The host of the public tunnel server.

If you want to make your local server aware of these headers, you can use the x-forwarded-fetch middleware in front of your HTTP server.

For more information, see How the Federation object recognizes the domain name section in the Federation document.

`-s`/`--service`: The tunneling service

The -s/--service option is used to specify the tunneling service to use. Available services can be found in the output of the fedify tunnel --help command. For example, to use the serveo.net, run the below command:

fedify tunnel --service serveo.net 3000
