# import/no-self-import

> Disallow a module from importing itself

A file that imports itself is almost always a mistake left over from a rename, a move, or an editor's auto-import. Everything it gets that way is already in scope, and `require()` returns the `exports` object before the file has finished filling it.

The rule resolves each path, so it also catches other spellings of the same file, such as `.` in an `index.js`. It checks `import`, `export .. from`, `import()` and `require()`.
