   Index.entryCount() does not return the number of staged files, rather the total number of files checked in at the current index. To get the number of staged changes you can use:

   const repo = await Repository.open(repoPath);
   const index = await repo.refreshIndex();
   
   const flags: Diff.OPTION = Diff.OPTION.IGNORE_WHITESPACE; // not needed, can be 0
   
   const head = await repo.getHeadCommit();
   
   // In an "empty" repository the `oldTree` parameter (here `await head.getTree()`) must be `undefined`.
   const stagedDiff = await Diff.treeToIndex(repo, await head.getTree(), index, { flags });
   const numberOfStagedChanges = stagedDiff.numDeltas();

   And to get the files which are changed, but not yet staged, could be something like:

   const unstagedDiff = await Diff.indexToWorkdir(repo, index, {
       flags: Diff.OPTION.INCLUDE_UNTRACKED | Diff.OPTION.SHOW_UNTRACKED_CONTENT | Diff.OPTION.RECURSE_UNTRACKED_DIRS | flags
   });
