Compared to other LLM frameworks, it offers these core benefits; cycles, controllability, and persistence.\n\n![graph image](https://raw.githubusercontent.com/Ashot72/CoinMarketCap-LangGraph-JS/refs/heads/main/public/CoinMarketCap_graph.png)\n\nIn this app, we created a LangGraph workflow using built-in and custom tools integrated with the [CoinMarketCap API](https://coinmarketcap.com/api/documentation/v1/#section/Authentication/). We defined our own states with the MessageAnnotation. The workflow is dynamically interrupted, as the app follows a human-in-the-loop (HITL) approach, requiring human intervention before proceeding with certain tasks.\n\nWe add tracing in [LangSmith](https://www.langchain.com/langsmith) to monitor model performance, trace execution flows, and evaluate LLM interactions, ensuring they operate efficiently and meet expectations.\n\n\nTo get started.\n```\n       # Clone the repository\n\n         git clone https://github.com/Ashot72/CoinMarketCap-LangGraph-JS\n         cd CoinMarketCap-LangGraph-JS\n\n       # Create the .env file based on the .env.example.txt file and include the respective keys.\n       \n       # installs dependencies\n         npm install\n\n       # to start\n         npm start\n      \n```\n\nGo to [CoinMarketCap LangGraph JS Video](https://youtu.be/faosBOaERnU) page\n\nGo to [CoinMarketCap LangGraph JS Description](https://ashot72.github.io/CoinMarketCap-LangGraph-JS/doc.html) page\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fashot72%2Fcoinmarketcap-langgraph-js","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fashot72%2Fcoinmarketcap-langgraph-js","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fashot72%2Fcoinmarketcap-langgraph-js/lists"}
