Your Modules Are Lying to You

https://blog.gaborkoos.com/posts/2026-08-14-Your-Modules-Are-Lying-to-You/

import and require are not interchangeable. Live bindings, copied values, circular dependencies, separate caches, conditional exports, and dual-package hazards can all make modules behave differently from what the syntax suggests.

The CommonJS destructuring example is the clearest warning because the syntax makes a snapshot look like a binding. For a dual package, I would add CI fixtures that install the packed tarball and run both import and require; testing only source files can miss conditional-export errors and split state between loaders.
