Integrations are a core component of LangChain.

Hey there, I am interested in merging my integration, I have a few questions here.

1. To create a new integration package, do we first fork and then integrate the package into it there, or is it a separate process? It looks like first you make the integration package, publish it to PyPi, and then you fork and clone the monorepo but only to alter the dogs?
2. There's a lot missing from the Polygon integration relative to the actual integration, how would you alter a pre-existing package?

1. your second sentence is correct! You don't integrate the package into a fork of langchain-ai/langchain. Instead, you manage the code for your integration out of your own repository.
2. In this case, would recommend copying the integration out (similar to how google has their main ChatVertexAI class in the langchain-ai/langchain-google repository, and @deprecated the old community integration. Good shout - I will add a guide for this

[dual-sharks]

Just to make sure I have this right:

1. Create the integration in a personal repository
2. Test and make sure it works
3. expose this on PyPi as a package.
4. alter only the docs of langchain to point to the PyPi package that you published.

[efriis]

correct! small nit, but in step [4] you also edit libs/packages.yml

Hi @efriis,

I created a PR that includes only the requested changes to the docs and libs/package.yml files. However, Vercel keeps failing because the following lacked providers pages: exa, prompty, sema4, google-genai, google-vertexai, google-community, nvidia-ai-endpoints, postgres, azure-dynamic-sessions, and sqlserver.

I went ahead provided provider pages for them : ) , but Vercel still fails : (. So now I've reverted back to my initial FalkorDB-specific commit.

Pls, could you clarify what I need to adjust to move this forward?
