ThingsDB Module (Go)

ThingsDB module written using the Go language.

With this module you gain access other scopes. This works both on the same node as with a connection to another ThingsDB cluster.

Installation

Install the module by running the following command in the @thingsdb scope:

new_module('thingsdb', 'github.com/thingsdb/module-go-thingsdb');

Optionally, you can choose a specific version by adding a @ followed with the release tag. For example: @v0.1.0.
