• Add layer property to ContextModule class and its serialization and deserialization methods (link, link, link)
• Set layer property of data object in ContextModuleFactory class from contextInfo object populated by ContextDependency class (link)
• Add new rule to webpack configuration file to assign dynamic-layer layer to files matching dynamic-module-layer in name (test/configCases/layer/rules/webpack.config.js, link)
• Add new test case file dynamic-module-layer.js to export an object with name, layer, and modules properties, where modules is an array of promises resolving to dynamic modules imported with dynamic resources (test/configCases/layer/rules/dynamic-module-layer.js, link)
• Add new test case files module1.js and module2.js to export objects with name and layer properties, where layer is a special variable __webpack_layer__ replaced by webpack at runtime (test/configCases/layer/rules/dynamic/module1.js, link; test/configCases/layer/rules/dynamic/module2.js, link)
• Import object from dynamic-module-layer.js and add new test case to assert that layer property of object and dynamic modules match dynamic-layer (test/configCases/layer/rules/index.js, link, link)
