createMetrics
The createMetrics function creates a Metrics object, and is the main entry point into the metrics module.
createMetrics(store: Store): MetricsA given Store can only have one Metrics object associated with it. If you call this function twice on the same Store, your second call will return a reference to the Metrics object created by the first.
Examples
This example creates a Metrics object.
const store = createStore();
const metrics = createMetrics(store);
console.log(metrics.getMetricIds());
// -> []
This example creates a Metrics object, and calls the method a second time for the same Store to return the same object.
const store = createStore();
const metrics1 = createMetrics(store);
const metrics2 = createMetrics(store);
console.log(metrics1 === metrics2);
// -> true
