TyphonLint-ThreadSafe

Thread Safety Analyzer for JavaScript Code

A package that analyzes JavaScript code snippets to detect potential race conditions and concurrency conflicts, helping developers ensure thread-safe implementations in multi-threaded environments like Node.js or web workers.

🚀 Installation

Install via pip:

pip install typhonlint_threadsafe

📝 Usage

Basic Usage (Default LLM7)

from typhonlint_threadsafe import typhonlint_threadsafe

# Analyze JavaScript code for thread safety
response = typhonlint_threadsafe(
    user_input="""
    // Example JavaScript code snippet
    let sharedVar = 0;
    function increment() {
        sharedVar++;
    }
    setInterval(increment, 100);
    """
)
print(response)

Custom LLM Integration

You can replace the default LLM (ChatLLM7) with any LangChain-compatible model:

Using OpenAI

from langchain_openai import ChatOpenAI
from typhonlint_threadsafe import typhonlint_threadsafe

llm = ChatOpenAI()
response = typhonlint_threadsafe(
    user_input="...",  # Your JS code here
    llm=llm
)

Using Anthropic

from langchain_anthropic import ChatAnthropic
from typhonlint_threadsafe import typhonlint_threadsafe

llm = ChatAnthropic()
response = typhonlint_threadsafe(
    user_input="...",  # Your JS code here
    llm=llm
)

Using Google Generative AI

from langchain_google_genai import ChatGoogleGenerativeAI
from typhonlint_threadsafe import typhonlint_threadsafe

llm = ChatGoogleGenerativeAI()
response = typhonlint_threadsafe(
    user_input="...",  # Your JS code here
    llm=llm
)

🔧 Parameters

Parameter	Type	Description
user_input	str	The JavaScript code snippet to analyze.
api_key	Optional[str]	LLM7 API key (if not provided, falls back to LLM7_API_KEY env var).
llm	Optional[BaseChatModel]	Custom LangChain LLM instance (defaults to ChatLLM7).

---

🔑 API Key & Rate Limits

• Default LLM: Uses ChatLLM7 from langchain_llm7.
• Free Tier: Sufficient for most use cases.
• Custom API Key: Pass via api_key parameter or LLM7_API_KEY env var.
• Get API Key: Register at LLM7.

---

📌 Features

• Detects race conditions in JavaScript code.
• Validates concurrency patterns.
• Structured output for easy integration.
• Supports custom LLMs for flexibility.

---

📝 Output
