EmscriptenModuleFactory

EmscriptenModuleFactory<T>: (moduleOverrides?: Partial<T>) => Promise<T>

Type parameters

T: EmscriptenModule = EmscriptenModule

Type declaration

- (moduleOverrides?: Partial<T>): Promise<T>
- A factory function is generated when setting the MODULARIZE build option to 1 in your Emscripten build. It return a Promise that resolves to an initialized, ready-to-call EmscriptenModule instance.
  
  By default, the factory function will be named Module. It’s recommended to use the EXPORT_ES6 option, in which the factory function will be the default export. If used without EXPORT_ES6, the factory function will be a global variable. You can rename the variable using the EXPORT_NAME build option. It’s left to you to export any global variables as needed in your application’s types.
  Parameters
  - optionalmoduleOverrides: Partial<T>
    Default properties for the initialized module.
  Returns Promise<T>
