My thoughts on Bun

Bun is a toolkit for running, building, testing, and debugging JavaScript and TypeScript projects. Robinson says developers want fewer tools to manage and a faster Node.js experience while keeping access to Node.js packages.

Robinson places Bun alongside earlier efforts to improve JavaScript tooling and runtime performance. He notes that Deno has added Node.js compatibility, while Rome was discontinued and its open-source work continued through a community project.

Bun allows CommonJS and ESM imports in the same file, helping developers work across projects that use both module systems. Robinson sees this as a useful way to absorb ecosystem complexity and suggests the Node.js community could discuss whether similar support belongs in Node.js.

Robinson appreciates Jarred's invitation to report Bun compatibility issues so the team can fix them. He says Bun's performance work deserves credit while Node.js contributors have focused on other priorities, including capabilities and security, and also do volunteer work.

Robinson is interested in using Bun as a runtime, toolkit, and package manager for projects he builds. He also raises the possibility of Bun support on Vercel.
