Tomorrow's ES modules today
summary
A production-ready NPM package called ESM enables ES module syntax in Node 6+ today by installing a loader that is ~200 KB (gzip ~64 KB), zero-dependency, and already sees 125+ releases. It provides a require hook for REPL, Mocha, Ava and webpack, a package-level bridge so one distribution serves both CJS and ESM, mutable namespace and named-export interop, caching plus engine code cache that promises ~20–30% startup gains, isolated loader contexts and multiple instances; it works in Electron.
