This is an example of a Stripes "platform". It consists simply of an NPM package.json that specifies the version of @folio/stripes and of any Stripes modules you wish to make available to generate client bundles.
Please see the quick start guide for more information.
The stripes.config.js is a configuration for a specific tenant. In general, a platform supports multiple tenants, each of which may include a different set of the available modules.
Copy the stripes.config.js file to be your stripes.config.js.local configuration file.
