encodeHeader

encodeHeader(header): Buffer

Defined in: packages/protocol/src/wire-format.ts:126

Encode a frame header into an 11-byte buffer.

WHY BINARY: JSON-RPC would add ~100 bytes overhead and require JSON.stringify. This header is just 11 bytes, written directly.

Parameters

header

FrameHeader

Returns

Buffer

Example

const header = encodeHeader({
  methodId: 1,
  flags: 0,
  requestId: 42,
  payloadLength: 1024,
});
// header is Buffer of 11 bytes
