rom-runtime 0.0.2

Python wrapper for the ROM browser-like runtime

rom-runtime

Python bindings for the ROM browser-like runtime.

This package exposes a thin Python API on top of ROM:

• eval()
• eval_async()
• eval_json()
• surface_snapshot()
• fingerprint_probe()
• run_fingerprintjs_harness()
• fingerprintjs_version()

It prefers a native PyO3 extension when available and falls back to the ROM CLI bridge otherwise.

Install

pip install rom-runtime

Usage

from rom import RomRuntime, has_native_binding

runtime = RomRuntime(
    {
        "href": "https://example.test/",
        "cors_enabled": False,
        "proxy_url": None,
    }
)
href = runtime.eval_async("(async () => location.href)()")
snapshot = runtime.surface_snapshot()

print("native:", has_native_binding())
print(href)
print(snapshot["fetch"])

Config keys use the Rust runtime field names, so use snake_case such as cors_enabled and proxy_url. cors_enabled is False by default.

Optional native build from source

python -m pip install maturin
python -m maturin build --manifest-path bindings/gom-python/Cargo.toml --release

Tagged GitHub releases build and publish wheels for Linux, Windows, and macOS, plus an sdist for source installs.

Common methods

• eval()
• eval_async()
• eval_json()
• surface_snapshot()
• fingerprint_probe()
• run_fingerprintjs_harness()
• fingerprintjs_version()

Environment

• ROM_FORCE_CLI_BRIDGE=1: disable the native path and force CLI fallback
• ROM_BRIDGE_BIN: explicit path to the rom_bridge executable
• ROM_BRIDGE_CWD: working directory used by the CLI fallback
