Quick Preview

Experience the power of automatic type inference:

import type { CodecSpec
, Infer
 } from 'binary-codec';
import { deserialize
 } from 'binary-codec';

const packetSpec
 = {
  byteLength
: 6,
  fields
: [
    {
      name
: 'status',
      type
: 'number',
      numberType
: 'uint',
      byteOffset
: 0,
      byteLength
: 1
    },
    {
      name
: 'message',
      type
: 'string',
      byteOffset
: 1,
      byteLength
: 5
    }
  ]
} as const
 satisfies CodecSpec
;

// ✨ Hover over PacketType to see the inferred type
type PacketType
 = Infer
<typeof packetSpec
>;

const buffer
 = new Uint8Array
(6);
// Hover over result to see the automatically inferred return type
const result
 = deserialize
(packetSpec
, buffer
);
