The aim of this library is to simplify the process of working with meteor server over DDP protocol using external JS environments

Under the hood this is DDPClient and meteor-sdk also simpleddp-plugin-login is integrated but those libraries are out of date and this was brought up to date with the latest typescript and tools. All browser related libraries were swapped out for the default node ones.
DDP (protocol) specification.
npm install simpleddp-node --save
