 You can also use the object form of the return value to configure additional properties of the module. Note that it's possible to return only properties and no code transformations.
 
-If `false` is returned for `moduleSideEffects` and no other module imports anything from this module, then this module will not be included even if the module would have side-effects. If `true` is returned, Rollup will use its default algorithm to include all statements in the module that have side-effects (such as modifying a global or exported variable). If `"no-treeshake"` is returned, treeshaking will be turned off for this module and it will also be included in one of the generated chunks even if it is empty. If `null` is returned or the flag is omitted, then `moduleSideEffects` will be determined by the `load` hook that loaded this module, the first `resolveId` hook that resolved this module, the `treeshake.moduleSideEffects` option, or eventually default to `true`.
