Part of: Microservices

KafkaParserConfig defines parser behavior for Kafka message payloads within the microservices configuration layer. Its keepBinary flag controls whether incoming Kafka values remain in their binary form instead of being converted during parsing.

Usage

ts
import type { KafkaParserConfig } from './interfaces/microservice-configuration.interface';

const parserConfig: KafkaParserConfig = {
  keepBinary: true,
};

// Use this when configuring a Kafka consumer/parser that must receive
// raw Buffer payloads, such as protobuf, Avro, or encrypted messages.

AI Coding Instructions

  • Set keepBinary: true when handlers need access to the raw Kafka Buffer payload.
  • Use keepBinary: false when message values should be parsed or converted before reaching application handlers.
  • Ensure downstream handlers match the configured payload type; binary payloads should not be treated as JSON strings without decoding.
  • Keep this configuration aligned with the message serializer and deserializer used by Kafka producers and consumers.
