LangChain Google Routes Tool

I developed a Google Routes tool into the LangChain.js framework. This tool enhances LangChain.js by enabling route calculations for various transport modes and providing detailed route information, improving the framework’s utility for developers. The PR for the tool can be checked at: https://github.com/langchain-ai/langchainjs/pull/5329

The tool itself can be found at: https://js.langchain.com/v0.2/docs/integrations/tools/google_routes
