Consumer ESLint rule#

Starting with beta.2, Marionette provides an ESLint flat-config plugin at marionette/eslint. Beta.1 does not export this subpath. Use the documentation matching the package artifact you installed.

// eslint.config.mjs
import marionette from 'marionette/eslint';

export default [marionette.configs.recommended];

The plugin requires ESLint 10. It has no runtime effect on a Marionette application and does not load any Marionette runtime module.

no-private-framework-members (MN0040)#

The recommended config reports dot-property access to a known private framework member when the receiver is proven to be a Marionette instance. The rule follows aliased named and namespace imports, local native subclasses, .extend() hierarchies, and constant variables initialized with new.

The private-member inventory is derived from the authored framework source and checked for stale names. It is a lint implementation detail, not a promise that private names will remain stable. An application's own _field is not assumed to be private framework state.

Computed properties, shadowed imports, mutable receiver or constructor bindings, and receivers whose identity cannot be proven are not classified. The rule has no autofix because choosing a public replacement requires application knowledge.

Deferred checks#

Literal UI-reference and named-handler checks are deferred. Marionette permits a subclass or constructor options to replace an inherited ui or event map, and initialize or preinitialize may install a named handler before delegation. A rule that inspects an extensible base definition alone would reject these valid patterns. These checks should ship only with a bounded construction model that can prove the effective configuration and handler surface.
