OptionalequalityFn

equalityFn?: (
    cachedOverrides: Partial<EmscriptenModule>,
    overrides: Partial<EmscriptenModule>,
) => boolean

A function to compare the cached overrides with the input overrides. So that the module promise can be reused if the overrides are the same. Defaults to a shallow equality function.

OptionalfireImmediately

fireImmediately?: boolean

Whether to instantiate the module immediately. If true, the module is eagerly instantiated and a promise of the module is returned. If false, only the overrides are updated and module instantiation is deferred to the first read/write operation.

Default

false

Optionaloverrides

overrides?: Partial<EmscriptenModule>

The Emscripten module overrides to be passed to the factory function. The locateFile function is overridden by default to load the WASM file from the jsDelivr CDN.
