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.
