no-reassign

Added rule no-reassign, made some mistakes publishing to npm. 😳

re-exports + messages

Aggregates ExportAllDeclaration names (export * from './third-module';).
Caches export map. (didn't seem to especially help in tests, but the files are tiny.)
named rule has a more informative message.

default + named

Rules check that your imports exist.

Note that if no imports exist in the imported file, no report is generated. Use the "es6-only" option to enforce exports on all files.

valid-relative-path

1st rule: you do not import relative files that don't exist.
