sourcetextmodule createcacheddata

• Returns: {Buffer}

Creates a code cache that can be used with the SourceTextModule constructor’s cachedData option. Returns a Buffer. This method may be called any number of times before the module has been evaluated.

// Create an initial module
const module = new vm.SourceTextModule('const a = 1;');
// Create cached data from this module
const cachedData = module.createCachedData();
// Create a new module using the cached data. The code must be the same.
const module2 = new vm.SourceTextModule('const a = 1;', { cachedData });
