core.config - Configuration

Puter's configuration object. This includes values from config.json or their defaults, and computed values like origin and api_origin.

const config = use('core.config');

extension.get('/get-origin', { noauth: true }, (req, res) => {
    res.send(config.origin);
})

Common utility functions used throughout Puter's backend. Use with caution as some of these functions may be deprecated.
