Getting started

Where is Edge Microgateway installed?

When you use npm with the global option (npm install -g edgemicro), the software is installed in [prefix]/lib/node_modules/edgemicro. You can find the value of [prefix] with this command:

npm config get prefix

The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On Windows, it's %AppData%\npm. The value of [prefix] is configurable. See npm-folders for more information about where Node.js modules are installed by default and how to configure the installation location.

Uninstalling Edge Microgateway

If you need to remove Edge Microgateway:

  1. Delete or archive the installation directory [prefix]/lib/node_modules/edgemicro, where [prefix] is the npm prefix as explained in Where is Edge Microgateway installed?
  2. Delete or archive the log files. By default, edgemicro-*.log files are in /var/tmp/, but this location is configurable. Check the Edge Microgateway configuration file if in doubt.
  3. Delete or archive the runtime config and cache config files:
    ~/.edgemicro/*.yaml
