Warnings

• gotcha akracer primarily addresses dynamic library issues for py_mini_racer on 64-bit ARM operating systems. While installing akracer may not hurt on other architectures, its primary benefit is for ARM users. On x86-64, py_mini_racer typically installs and compiles correctly without akracer.
  Fix: Only install akracer if you are on a 64-bit ARM operating system and experiencing issues with py_mini_racer's native installation. Otherwise, `pip install py_mini_racer` might suffice.
• breaking The project is currently in '4 - Beta' development status according to PyPI. This indicates that the API or stability might not be fully mature and could be subject to breaking changes in future releases.
  Fix: Monitor release notes and the GitHub repository for updates and potential breaking changes. Consider pinning to specific minor versions to mitigate unexpected issues.
• gotcha A security analysis by ReversingLabs indicated that the akracer package contains 'risks' and 'known severe vulnerabilities' that are actively being exploited. Users should review the analysis results before use.
  Fix: Exercise caution and consult the latest security reports for the library. Implement robust security practices in projects using akracer, such as regular dependency scanning and ensuring isolated execution environments.

Install

• pip install akracer Install akracer

Imports

• MiniRacer

  from py_mini_racer import MiniRacer

  akracer acts as a provider of underlying binaries for py_mini_racer, so the primary interaction is still through the py_mini_racer library itself.

Quickstart

This quickstart demonstrates basic usage of py_mini_racer, which akracer enables by providing the necessary underlying binaries, especially for ARM-based systems. It shows how to evaluate JavaScript expressions and call JavaScript functions within a Python environment.

import os
from py_mini_racer import MiniRacer

# Initialize a MiniRacer context
context = MiniRacer()

# Evaluate JavaScript code
result = context.eval("1 + 1")
print(f"Result of '1 + 1': {result}")

# Call a JavaScript function
context.eval("var add = function(a, b) { return a + b; };")
add_result = context.call("add", 5, 3)
print(f"Result of add(5, 3): {add_result}")

# Example using a JavaScript file (simulate loading a file)
js_content = """
var greet = function(name) {
    return 'Hello, ' + name + '!';
};
"""
context.eval(js_content)
greet_result = context.call("greet", "World")
print(f"Result of greet('World'): {greet_result}")
