Hey team, I've flagged this PR for your review as it introduces a new fetch request in the _makeRequest method. This is a net-new, non-api client external HTTP request, and I wanted to bring it to your attention for further review.

[tolares]

Their is no official Stack Exchange NPM package that wrap the API so I used the fetch directly

Could you add a docs page?

couple nits, besides that it lgtm! thanks for handling this.

Will merge tmro when I cut a release. Thank you!

[bracesproul]

Hmm, looks like formatting is failing. Could you run yarn format and push the changes? Thanks

[tolares]

Thank you for spotting the format issue @bracesproul . I have fixed them and apply your proposal to have some cleaner jsdoc

[tolares]

Sorry I think my last commit didn't include the fix will push it asap

[bracesproul]

Ah woops, you need to add this new module to libs/langchain-community/langchain.config.js see docs here

Pushed a commit running yarn build

This is required after you add a new entrypoint b/c it adds it to the package.json and updates the gitignore to not commit build artifacts
