Add Reddit Document Loader and Tool Support for LangchainJS

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

Request to have a document loader and tool for Reddit in LangchainJS. It is already an integration in the Python version of Langchain and would be a great enhancement to have in LangchainJS. The Reddit document loader and tool will have the same functionality as the Python version:

• Fetch and load posts from Reddit based on search queries
• Load posts either from specific subreddits or users
• Load posts from specific categories like “hot”, “top”, “new” etc

Motivation

Reddit is a major social media platform hosting a diverse range of discussions and user-generated content, widely utilized by our team and many others. Using the Reddit API, we can seamlessly search and retrieve posts. Having this integration would provide a gateway for those who need to use Reddit as a document source or a tool to query for specific Reddit posts.

Proposal (If applicable)

We are a team of four that is eager to contribute to LangchainJS. We will develop the Reddit Document Loader and Reddit tool using the Reddit API and contribute it as a community package to LangchainJS to further expand its capabilities. The functionalities will be the same as the Reddit integration in the Python version.

Hey @jacoblee93 , just following up on the idea I posted earlier. Do you think it's something we can create an issue for and work on?

It would be pretty nice to get posts from Reddit, directly on langchain. And, by my understanding, it would make the JS version more similar to the Python version, at least in terms of features implemented.
