Please Wait... Loading: A Talk of Two Loaders
summary
Node.js implements ES modules behind --experimental-modules with ESM files forced to use dot MJS extension, no transparent CJS interop (CJS imports appear as a default), and CJS-to-ESM requires the createRequire workaround plus fileURL handling. A 49‑member modules team across ~10 countries and ~10 companies produces a minimal kernel (phase one) that omits Node resolver features; phase plan adds extensible userland loaders and performance work. Runtime supports dynamic import and import.meta today; goal is unflagged shipping by Node 12.
