const { HealthChecker, HealthStatus } = require('@wiredcraft/health-checks');
const healthChecker = new HealthChecker();
healthChecker.addCheck(async () => {
if (Math.random() > 0.5) {
throw new Error('RandomFailure');
}
}, 'db', HealthStatus.Unhealthy.name, ['default', 'all']);
healthChecker.addCheck(async () => {
if (Math.random() > 0.5) {

}
}, 'external-service', HealthStatus.Degraded.name, ['all']);
// By default, it will filter checks which includes 'default' tag
const res = await healthChecker.getStatus();
// res will be something like
// {
// "status": "unhealthy",
// "checks": [
// {
// "name": "db",
// "state": "unhealthy",
// "data": {
// "reason": "RandomFailure"
// }
// }
// ]
// }
// You can use other tag to filter the checks
const res = await healthChecker.getStatus('all');
// res will be something like
// {
// "status": "degraded",
// "checks": [
// {
// "name": "db",
// "state": "healthy",
// "data": {
// "reason": ""
