/**
* Base implementation for all JavaScript SDK clients.
*
* Call the constructor with the corresponding options
* specific to the client subclass. To access these options later, use
* {@link Client.getOptions}.
*
* If a Dsn is specified in the options, it will be parsed and stored. Use
* {@link Client.getDsn} to retrieve the Dsn at any moment. In case the Dsn is
* invalid, the constructor will throw a {@link SentryException}. Note that
* without a valid Dsn, the SDK will not send any events to Sentry.
*
* Before sending an event, it is passed through
* {@link BaseClient._prepareEvent} to add SDK information and scope data
* (breadcrumbs and context). To add more custom information, override this
* method and extend the resulting prepared event.
*
* To issue automatically created events (e.g. via instrumentation), use
* {@link Client.captureEvent}. It will prepare the event and pass it through
* the callback lifecycle. To issue auto-breadcrumbs, use
* {@link Client.addBreadcrumb}.
*
* @example
* class NodeClient extends BaseClient {
* public constructor(options: NodeOptions) {
* super(options);
* }
*
* // ...
* }
