esdf/utils/index.js

a frugal event-sourced domain-driven design framework with elements of cqrs

/**
 * Attaches a label with a given value to the error object given as the first argument.
 * Labels are stored under the "labels" property of the error object with the label name used as the key. Label values can be of any type.
 * If the error is not enrichable (is not an object), this function intentionally does nothing, to avoid breaking the flow when errors are scalars.
 * 
 * @param err The error object to be enriched with the label given.
 * @param {String} label_name The label key, to be stored under the "labels" property of the error.
 * @param label_value The label value. Can be any scalar value. Putting names of error-handling layers (catch, callback wrappers) here is usually a good idea.
