lmdb-extend

A small utility to support extending the functionality of LMDB databases

Installation

npm install lmdb-extend

API

functioon extend(db:lmdbDatabase, extensions:object) - returns db

Extends an LMDB root database and any child databases it opens to have the extensions.

In order to support over-riding built-in behavior, if the extension is a function and the database already has a function with the same name, the extension will be called with the original function as the first argument already bound to the database instance. It is up to the developer to call the original function at the appropriate time if desired.

Testing

Testing is conducted using jest.
