• 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)

Hello, Is this open for external help?

Hi! I’m new to contributing to webpack docs and I’ve been reading about layers and dynamic imports.
Is this issue still open for external contributions? If so, I’d be happy to work on the documentation update.
Thanks!
