ffx-to-js

Convert an After Effects .ffx file into a JS-escaped binary string, optionally wrapped in an ExtendScript helper to recreate the file.

CLI

ffx-to-js <path> [-o <output.js>] [--var <name>] [--file-name <name.ffx>]
        [--resource-folder <path>] [--raw]

• Default output: <input base>.js
• Default names: inferred from embedded controlName when present, otherwise the input name.

Install / run

npm install -g ffx-to-js
# or
npx ffx-to-js <path>
# or (local dev)
npm run bin <path>

[!NOTE] bun can be used instead of npm, but npm is the target.

Library

import {
  fileToBinaryString,
  fileToFfxScript,
  writeBinaryStringToTxt,
} from "ffx-to-js";

// Returns binary string
const binary = await fileToBinaryString("./preset.ffx");

// Returns full JS code (binary string + script)
const script = await fileToFfxScript("./preset.ffx");

// Saves JS code as file
await writeBinaryStringToTxt("./preset.ffx", "./preset.js");
