So it is enough to create only - * two chunks A containing [AB] and C containing [C]. - * - * So we do not assign the dynamic entry C as dependent entry point to modules - * that are already loaded. - * - * In a more complex example, let us assume that we have entry points X and Y. - * Further, let us assume - * X -> A, X -> B, X -> C, - * Y -> A, Y -> B, - * A => D, - * D -> B, D -> C - * So without dynamic import optimization, the dependent entry points are - * A: XY, B: DXY, C: DX, D: D, X: X, Y: Y, so we would for now create six - * chunks. - * - * Now D is loaded only after A is loaded. But A is loaded if either X is - * loaded or Y is loaded. So the modules that are already in memory when D is - * loaded are the intersection of all modules that X depends on with all - * modules that Y depends on, which in this case are the modules A and B. - * We could also say they are all modules that have both X and Y as dependent - * entry points. - * - * So we can remove D as dependent entry point from A and B, which means they - * both now have only XY as dependent entry points and can be merged into the - * same chunk. - * - * Now let us extend this to the most general case where we have several - * dynamic importers for one dynamic entry point. - * - * In the most general form, it works like this: - * For each dynamic entry point, we have a number of dynamic importers, which - * are the modules importing it. Using the previous ideas, we can determine - * the modules already in memory for each dynamic importer by looking for all - * modules that have all the dependent entry points of the dynamic importer as - * dependent entry points. - * So the modules that are guaranteed to be in memory when the dynamic entry - * point is loaded are the intersection of the modules already in memory for - * each dynamic importer. - * - * Assuming that A => D and B => D and A has dependent entry points XY and B - * has dependent entry points YZ, then the modules guaranteed to be in memory - * are all modules that have at least XYZ as dependent entry points. - * We call XYZ the *dynamically dependent entry points* of D. - * - * Now there is one last case to consider: If one of the dynamically dependent - * entries is itself a dynamic entry, then any module is in memory that either - * is a dependency of that dynamic entry or again has the dynamic dependent - * entries of that dynamic entry as dependent entry points. - * - * A naive algorithm for this proved to be costly as it contained an O(n^3) - * complexity with regard to dynamic entries that blew up for very large - * projects. - * - * If we have an efficient way to do Set operations, an alternative approach - * would be to instead collect already loaded modules per dynamic entry. And as - * all chunks from the initial grouping would behave the same, we can instead - * collect already loaded chunks for a performance improvement. - * - * To do that efficiently, need - * - a Map of dynamic imports per dynamic entry, which contains all dynamic - * imports that can be triggered by a dynamic entry - * - a Map of static dependencies per entry - * - a Map of already loaded chunks per entry that we initially populate with - * empty Sets for static entries and Sets containing all entries for dynamic - * entries - * - * For efficient operations, we assign each entry a numerical index and - * represent Sets of Chunks as BigInt values where each chunk corresponds to a - * bit index. Then the last two maps can be represented as arrays of BigInt - * values. - * - * Then we iterate through each dynamic entry.

While side effects are usually things like global function calls, - * global variable mutations or potentially thrown errors, details do not - * matter here, and we just discern chunks without side effects (pure chunks) - * from other chunks. - * - * As a first step, we assign each pre-generated chunk with side effects a - * label. I.e. we have side effect "A" if the non-pure chunk "A" is loaded. - * - * Now to determine the side effects of loading a chunk, one also has to take - * the side effects of its dependencies into account. So if A depends on B - * (A -> B) and both have side effects, loading A triggers effects AB. - * - * Now from the previous step we know that each chunk is uniquely determine by - * the entry points that depend on it and cause it to load, which we will call - * its dependent entry points. - * - * E.g. if X -> A and Y -> A, then the dependent entry points of A are XY. - * Starting from that idea, we can determine a set of chunks—and thus a set - * of side effects—that must have been triggered if a certain chunk has been - * loaded. Basically, it is the intersection of all chunks loaded by the - * dependent entry points of a given chunk. We call the corresponding side - * effects the correlated side effects of that chunk. - * - * Example: - * X -> ABC, Y -> ADE, A-> F, B -> D - * Then taking dependencies into account, X -> ABCDF, Y -> ADEF - * The intersection is ADF. So we know that when A is loaded, D and F must also - * be in memory even though neither D nor A is a dependency of the other. - * If all have side effects, we call ADF the correlated side effects of A. The - * correlated side effects need to remain constant when merging chunks. - * - * In contrast, we have the dependency side effects of A, which represents - * the side effects we trigger if we directly load A. In this example, the - * dependency side effects are AF. - * For entry chunks, dependency and correlated side effects are the same. - * - * With these concepts, merging chunks is allowed if the correlated side - * effects of each entry do not change. Thus, we are allowed to merge two - * chunks if - * - * a) the dependency side effects of each chunk are a subset of the correlated - * side effects of the other chunk, so no additional side effects are - * triggered for any entry, or - * b) The dependent entry points of chunk A are a subset of the dependent entry - * points of chunk B while the dependency side effects of A are a subset of - * the correlated side effects of B. Because in that scenario, whenever A is - * loaded, B is loaded as well. But there are cases when B is loaded where A - * is not loaded. So if we merge the chunks, all dependency side effects of - * A will be added to the correlated side effects of B, and as the latter is - * not allowed to change, the former need to be a subset of the latter. - * - * Another consideration when merging small chunks into other chunks is to - * avoid - * that too much additional code is loaded. This is achieved when the dependent - * entries of the small chunk are a subset of the dependent entries of the - * other - * chunk. Because then when the small chunk is loaded, the other chunk was - * loaded/in memory anyway, so at most when the other chunk is loaded, the - * additional size of the small chunk is loaded unnecessarily. - * - * So the algorithm performs merges in two passes: - * - * 1. First we try to merge small chunks A only into other chunks B if the - * dependent entries of A are a subset of the dependent entries of B and the - * dependency side effects of A are a subset of the correlated side effects - * of B. - * 2.
