    environment: Environment

    Vite-specific environment instance

    fs: RolldownFsModule

    Provides abstract access to the file system.

    meta: PluginContextMeta

    An object containing potentially useful metadata.

    Methods

    getModuleInfo: (moduleId: string) => ModuleInfo | null

    Get additional information about the module in question.

    Type Declaration

      • (moduleId: string): ModuleInfo | null

      • Parameters

        • moduleId: string

        Returns ModuleInfo | null

        Module information for that module. null if the module could not be found.

    • Resolve imports to module ids (i.e. file names) using the same plugins that Rolldown uses, and determine if an import should be external.

      When calling this function from a resolveId hook, you should always check if it makes sense for you to pass along the options.

      Parameters

      Returns Promise<ResolvedId | null>

      If Promise<null> is returned, the import could not be resolved by Rolldown or any plugin but was not explicitly marked as external by the user. If an absolute external id is returned that should remain absolute in the output either via the makeAbsoluteExternalsRelative option or by explicit plugin choice in the resolveId hook, external will be "absolute" instead of true.

    Logging Methods

    debug: (
        log: string | RolldownLog | (() => string | RolldownLog),
        pos?: number | { column: number; line: number },
    ) => void

    Same as PluginContext.debug, but a position param can be supplied.

    info: (
        log: string | RolldownLog | (() => string | RolldownLog),
        pos?: number | { column: number; line: number },
    ) => void

    Same as PluginContext.info, but a position param can be supplied.

    warn: (
        log: string | RolldownLog | (() => string | RolldownLog),
        pos?: number | { column: number; line: number },
    ) => void

    Same as PluginContext.warn, but a position param can be supplied.

    • Same as PluginContext.error, but the id of the current module will also be added and a position param can be supplied.

      Parameters

      • e: string | RolldownError
      • Optionalpos: number | { column: number; line: number }

      Returns never
