What's new

v0.7.0:

• Moved to Monorepo
• Updated some Typescript Types: they caused build errors with the Monorepo setup

v0.6.0:

• Fixed error reporting to application insights, it now properly reports all properties including innerErrorsProperties.
• Fixed baseError, it now properly supports nested innerErrors. Exception/inner Error used to overwrite each others property if they had the same name.
• BaseError now has errorTraceId, either from backEnd, or a unique frontEnd id
• BaseError helper methods added for getting properties or propertyByName

It's recommended to create your own error types, extending BaseError, and decorate it with your own fields:

    export class PdfError extends BaseError {
        docNo: string;
        constructor(args: { message: string; docNo: string; innerError?: Error }) {
            super({ name: 'PdfError', message: args.message, innerError: args.innerError });
            this.docNo = args.docNo;
        }
    }

Breaking Changes

v0.6.0:

• Renamed initializeError to initializeNetworkError and simplified it. It now only takes NetworkErrorArgs as argument.
• BaseError now properly support nested (and nested-nested) errors with argument innerError.
  Earlier properties with the same name would overwrite each other.
  exception argument renamed to innerError, of type Record<string, unknown> | Error
• BaseError doesn't add properties directly onto itself anymore, but uses nested errors with argument innerError.
• Instead of BaseError.allProperties()["someCustomProperty"] use BaseError.findPropertyByName("someCustomProperty"). Since we now use innerError of type Error or Record<string, unknown>, the property has been moved from baseError[property] to baseError.innerError[property].
• Moved EchoEvents enum to EchoCore.
• Changed types for EventHub event keys in all functions from string | EchoEvents to string only.

v0.5.0:

• SubClasses of BaseError will not get the name of the class automatically anymore, but have to specify it. This to avoid name obfuscation/minify to a single letter in appInsight.

Example implementation:

export class CustomError extends BaseError {
    constructor(args: ErrorArgs) {
        super({ ...args, name: 'CustomError' });
    }
}
