Installation

Fedify is available on JSR for Deno and on npm for Node.js and Bun.

TIP

We recommend using Deno or Bun (which are TypeScript-first) for the best experience, but you can use Node.js if you prefer.

Deno

Deno is the primary runtime for Fedify. As a prerequisite, you need to have Deno 1.41.0 or later installed on your system. Then you can install Fedify via the following command:

deno add @fedify/fedify

Since Fedify requires Temporal API, which is an unstable feature in Deno as of May 2024, you need to add the "temporal" to the "unstable" field of the deno.json file:

{
  "imports": {
    "@fedify/fedify": "jsr:@fedify/fedify"
  },
  "unstable": ["temporal"]
}

Node.js

Fedify can also be used in Node.js. As a prerequisite, you need to have Node.js 20.0.0 or later installed on your system. Then you can install Fedify via the following command:

npm add @fedify/fedify

Fedify is an ESM-only package, so you need to add "type": "module" to the package.json file:

{
  "type": "module",
  "dependencies": {
    "@fedify/fedify": "^0.8.0"
  }
}

Bun

Fedify can also be used in Bun. You can install it via the following command:

bun add @fedify/fedify
