LangGraph Studio With Local Deployment
!!! warning "Browser Compatibility" Viewing the studio page of a local LangGraph deployment does not work in Safari. Use Chrome instead.
Setup
Make sure you have setup your app correctly, by creating a compiled graph, a .env file with any environment variables, and a langgraph.json config file that points to your environment file and compiled graph. See here for more detailed instructions.
After you have your app setup, head into the directory with your langgraph.json file and call langgraph up -c langgraph.json --watch to start the API server in watch mode which means it will restart on code changes, which is ideal for local testing. If the API server start correctly you should see logs that look something like this:
Ready!
- API: http://localhost:8123
2024-06-26 19:20:41,056:INFO:uvicorn.access 127.0.0.1:44138 - "GET /ok HTTP/1.1" 200
Read this reference to learn about all the options for starting the API server.
Access Studio
Once you have successfully started the API server, you can access the studio by going to the following URL: https://smith.langchain.com/studio/?baseUrl=http://127.0.0.1:8123 (see warning above if using Safari).
If everything is working correctly you should see the studio show up looking something like this (with your graph diagram on the left hand side):
