arc-applescript-api

A wrapper for Arc Browser's basic AppleScript APIs.

It partially implements Arc's AppleScript dictionary and exports functions for interacting with Arc from Node.js runtime. Might be helpful for writing small automations (e.g. using ScriptKit).

Requires Node.js 16+.

Install

npm install @kkoscielniak/arc-applescript-api

Usage

import { openTab } from "@kkoscielniak/arc-applescript-api";

await openTab("https://koscielniak.pro");

Contributing

This project is a side effect of my experiments with automating the Arc Browser. Its feature-set is limited as of now. I am gradually adding the features whenever I need them.

If there's a missing feature, a bug, or other improvement you'd like, I encourage you to contribute. Feel free to open an issue or, even better, a Pull Request.
