trying to get number of files to avoid empty commits using entryCount(), but it is returning a number > 0 even if there is no file to commit

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
});
