import hapiHealthcheck from 'hapi-health-check'

Server.register({ register: hapiHealthcheck, // options are explained below. Options are not mandatory. Default values are the one used in this snippet. options: { path: '/status', health_checks: {}, custom_health_checks: [], feature_health_checks: {}, custom_feature_health_checks: [], } }, (err) => { // handle error

})

.Use built-in healthchecks

Server.register({ register: hapiHealthcheck, options: { path: '/status', // you can choose among all these built-in health checks health_checks: { type: 'postgres', options: { url: 'POSTGRES_URL', ssl: false // default value }, { type: 'redis', options: { url: 'REDIS_URL' }, { type: 's3', options: { access_key_id: 'ACCESS_KEY_ID', secret_access_key: 'SECRET_ACCESS_KEY' }, { type: 'nats', options: { url: 'NATS_URL' } }

Other options are the following :

• custom_health_checks : an array of functions doing custom health checks.
• feature_health_checks : same type of array as health_checks but if one of theses checks fail, the plugin will not return a failure but a warning.
