Freshly Toasted: How Bun stable version is Heating Up JS & TS Development
summary
Bun 1.0 is a single toolkit combining package manager, test runner, and bundler plus a runtime; the talk shows concrete demos and microbenchmarks using hyperfine (warm‑ups and 10 runs) comparing bun install to pnpm/npm/yarn (roughly 2× faster than pnpm, ~3× vs npm, ~4× vs yarn in the demo), bun test about 1.3× faster than vitest in CI-style runs, and bundling roughly on par or slightly faster than esbuild/rollup/parcel/webpack. Demos exercise global cache, workspaces, lifecycle scripts, source maps and minification and the builds and tests run successfully.
