Thank you for your contribution.

1. there are quite a lot of console.log, as I understand this might be useful sometimes (are they visible to the end-users?), you might want to extract the logging function into a separate Logger class, which could be configured to write to log files (persistent for debuging purpose)
2. You might want to format your code, as some are not properly styled.
3. for Javascript, you might want to cache array length in a for loop such as for (let i = 0, len = groupedTxs[index].length; i < len; i++) {
4. Inconsistent usage of semi-colon
5. var could be completely replaced by either let or const
6. commented out code that is misleading. such as
   
7. Missing exception handling when e.g. MongoDB is not accessible.
8. Nested try-catch all catch general exceptions is not a good idea e.g. code-smell.
9. Regarding this commit not sure why it has shown changes even quite a lot of code are actually un-changed.
