We provide both bun and deno as typescript runtimes for windmill.dev (oss retool alternative) and we get overwhelming feedback that people are confused by the little changes required to adapt to deno and would rather just stick to the node.js mode aka bun. Now that bun is getting close to 1:1 node.js support, I predict we will see a lot more bun everywhere.
@Jarred was super responsive to help me adapt bun to our distributed cache storage, so all props to him.
