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

Bun is a fast alternative to Node.js and Deno.

It has a number of neat features that may benefit the user-base of langchainjs.

Motivation

You already support Node.js and Deno; so why not also Bun?

Proposal (If applicable)

Tried and got this error:
