Utiliser MessagePack pour efficient binary serialization
MessagePack packs JSON-comme données en un compact binary formater, reducing taille et parsing time. Popular en high-performance APIs et IoT.

MessagePack is a binary serialization format that represents JSON-like data in fewer bytes. It uses a type-length-value encoding: small integers fit in 1 byte, short strings in 1-2 bytes, and there are no delimiters or quotes. It is faster to encode/decode than JSON because it avoids text parsing.

Coder the MessagePack binary output as base64 for transport through text channels. MessagePack produces raw bytes — base64 makes them safe for JSON fields, HTTP headers, or logs. The receiver reverses: base64 decode → MessagePack unpack.
- 3 Encodeur hexadécimal →
Alternatively, encode as hex for debugging — hex is human-readable and lets you inspect the MessagePack byte structure. Each byte shows the type and value encoding. Use this for protocol debugging, not production transport (hex is 2x larger than base64).

Use MessagePack for: internal microservice communication (gRPC-like efficiency without protobuf schema), IoT (small payloads), and caching (smaller Redis values). For public APIs, use JSON with content negotiation — support both application/json and application/x-msgpack.
Questions fréquentes
- MessagePack vs Protobuf?
- Protobuf requires a schema (.proto file) and generates code — smaller and faster but less flexible. MessagePack is schemaless like JSON — easier to use but slightly larger. Use Protobuf for stable, high-volume internal APIs; MessagePack for flexibility or when schemas change often.
- Can I use MessagePack in the browser?
- Yes. Libraries like @msgpack/msgpack provide fast encoding/decoding. For HTTP, use content negotiation: send Accept: application/x-msgpack and decode the binary response. For WebSocket, send/receive ArrayBuffer directly.
