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

``bash
ffx-to-js [-o ] [--var ] [--file-name ]
[--resource-folder ] [--raw]
`

- Default output: .js
- Default names: inferred from embedded controlName when present, otherwise the input name.

$3

`bash
npm install -g ffx-to-js


or

npx ffx-to-js

or (local dev)

npm run bin
`

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

Library

`ts
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");
``
