Repl errors and limitations

[dryprogrammer]

Hi, I discovered this from the LangServe blog. Thanks for the repl for a quickstart, but I think it's misleading and maybe a deadend for langchain & repl nix newbies.

Maybe you can elaborate that this is not for deployment, and direct them to a different replit where securing the endpoint is simpler, perhaps with an nginx in front like https://replit.com/@ritza/nix-template

Also Replit nix doesn't allow many pkgs such as pkgs.ollama so it might help others to install a small model to your repl. Llama2 didn't run for me probably due to RAM/Swap space:
https://replit.com/@dryprogrammer/langserve-replit-template

Errors:

langserve-replit-template/.replit

Line 6 in 6aca25d

entrypoint = "main.py"

main.py should be app/server.py

langserve-replit-template/.replit

Line 15 in 6aca25d

run = ["sh", "-c", "langserve serve"]

langserve serve should be langchain serve --host 0.0.0.0

Also /pirate-speak/playground/ doesn't work without trailing slash, and even with, it doesn't work.
