Node v18.6.0 (Current)

Notable Changes

Experimental ESM Loader Hooks API

Node.js ESM Loader hooks now support multiple custom loaders, and composition is achieved via "chaining": foo-loader calls bar-loader calls qux-loader (a custom loader must now signal a short circuit when intentionally not calling the next). See the ESM docs for details.

Real-world use-cases are laid out for end-users with working examples in the article Custom ESM loaders: Who, what, when, where, why, how.
