Benefits

  • Dead-simple installation and setup: npm install --save reify, require("reify")
  • Works with every version of Node.
  • Put import and export statements anywhere you like.
    • They're just statements.
    • If you have a philosophical preference for restricting them to the top-level, there are plenty of ways to enforce that.
    • This library doesn't limit you either way.
  • Imported symbols are just normal variables.
    • Debuggers and dev tools display the symbols as you wrote them, unmangled by a transpiler.
    • Not having to rename variables references leads to much faster compilation.
    • Variables are confined to the scope where they were imported.
    • import statements work in the Node REPL.
  • Any existing module or package can be imported.
    • Babel's interopRequire{Default,Wildcard} logic is captured by Module.prototype.getExportByName.
  • Does not interfere with existing require.extensions hooks.
  • Much simpler transform implementation as compared with other ECMASCript module compilers.
    • import statements become calls to module.importSync(id, setters)
    • export statements become assignments to the exports object.
    • The compiler doesn't have to parse the entire file to find import and export statements.
  • Line numbers are strictly preserved.
    • No hoisting of import statements.
    • All import and export statements are compiled in-place.
  • No need for Object.defineProperty-style getters to support export * from "...".
  • The module.importSync(id, setters) API is human-writable, too, if you want to implement custom update logic.
  • Generated code is statically analyzable, since the exports object is not exposed.
