ConcatenationScope

Tracks the symbols and cross-module references needed while rendering a concatenated module.

new ConcatenationScope(modulesMap, currentModule, usedNames): ConcatenationScope

Creates the mutable scope object used while rendering a concatenated module and its cross-module references.

concatenationScope.createModuleReference(module, __namedParameters): string

Encodes a reference to another concatenated module as a placeholder identifier that can be parsed later during code generation.

concatenationScope.getRawExport(exportName): string | undefined

Returns the raw expression registered for an export, if one exists.

concatenationScope.isModuleInScope(module): boolean

Checks whether a module participates in the current concatenation scope.

concatenationScope.registerExport(exportName, symbol): void

Records the symbol that should be used when the current module exports a named binding.

concatenationScope.registerNamespaceExport(symbol): void

Records the symbol that should be used for the synthetic namespace export.

concatenationScope.registerRawExport(exportName, expression): void

Records a raw expression that can be used to reference an export without going through the normal symbol map.

concatenationScope.setRawExportMap(exportName, expression): void

Replaces the raw expression for an export only when that export already has an entry in the raw export map.

ConcatenationScope.isModuleReference(name): boolean

Checks whether an identifier is one of webpack's encoded concatenation module references.

ConcatenationScope.matchModuleReference(name): ModuleReferenceOptions & { index: number } | null

Parses an encoded module reference back into its module index and reference flags.
