An example implementation of machine activation and process heartbeats using Keygen

Primary LanguageJavaScriptMIT LicenseMIT

Example Process Heartbeats

This is an example of machine activation and process heartbeats. Machine activation allows you to limit the number of devices used by a license, while processes allow you to limit application concurrency. For example, the demo credentials will allow up to 3 machine activations and up to 3 concurrent processes across all machines.

Running the example

First up, configure a few environment variables:

# Your Keygen account ID. Find yours at https://app.keygen.sh/settings.
export KEYGEN_ACCOUNT_ID="YOUR_KEYGEN_ACCOUNT_ID"

You can either run each line above within your terminal session before starting the app, or you can add the above contents to your ~/.bashrc file and then run source ~/.bashrc after saving the file.

Next, install dependencies with yarn:

yarn

Activating a machine

To perform a machine activation, run the script and supply a valid license key:

yarn start

If the license key is valid, the script will attempt to active the current machine and then it will maintain process heartbeats, until a SIGINT signal is sent to the process.

To use demo credentials, you can run the following:

KEYGEN_ACCOUNT_ID=demo yarn start

Enter C1B6DE-39A6E3-DE1529-8559A0-4AF593-V3 when prompted.
