Module @exodus/bytes/encoding-lite.js

The exact same exports as @exodus/bytes/encoding.js are also exported as @exodus/bytes/encoding-lite.js, with the difference that the lite version does not load multi-byte TextDecoder encodings by default to reduce bundle size 10x.

import { TextDecoder, TextEncoder } from '@exodus/bytes/encoding-lite.js'
import { TextDecoderStream, TextEncoderStream } from '@exodus/bytes/encoding-lite.js' // Requires Streams

// Hooks for standards
import { getBOMEncoding, legacyHookDecode, labelToName, normalizeEncoding } from '@exodus/bytes/encoding-lite.js'
Copy

The only affected encodings are: gbk, gb18030, big5, euc-jp, iso-2022-jp, shift_jis and their labels when used with TextDecoder.

Legacy single-byte encodingds are loaded by default in both cases.

TextEncoder and hooks for standards (including labelToName / normalizeEncoding) do not have any behavior differences in the lite version and support full range if inputs.

To avoid inconsistencies, the exported classes and methods are exactly the same objects.
