ESM

The talk introduces Bun 1.0 as a fast JavaScript and TypeScript toolkit for running, building, testing, and debugging codebases. It explains the frustrations Bun aims to address: fragmented tooling and demand for faster Node.js. The speaker highlights Bun’s handling of CommonJS and ESM imports, its goal of compatibility with the Node.js ecosystem, and its focus on performance, while acknowledging Node.js’s own work and priorities. The talk closes with enthusiasm for Bun as a runtime, toolkit, and package manager, and interest in possible support on Vercel.
