# `@borewit/text-codec`
|
||
|
||
A **lightweight alternative implementation** of `TextEncoder` / `TextDecoder` supporting common encodings missing in some JavaScript engines and Node.js builds.
|
||
Works in environments like **Hermes** (React Native) or **Small-ICU Node.js** where only UTF-8 and UTF-16LE are available.
|
||
|
||
| Encoding | Hermes — **Encode** | Hermes — **Decode** | Small-ICU Node.js — **Encode** | Small-ICU Node.js — **Decode** |
|
||
|---------------------------|---------------------|---------------------|--------------------------------|--------------------------------|
|
||
| **utf-8** / `utf8` | ➕ | Native | Native | Native |
|
||
| **utf-16le** | ➕ | ➕ | Native | Native |
|
||
| **ascii** | ➕ | ➕ | ➕ | ➕ |
|
||
| **latin1** / `iso-8859-1` | ➕ | ➕ | ➕ | Native (sometimes) |
|
||
| **windows-1252** | ➕ | ➕ | ➕ | ➕ |
|
||
|
||
**Legend:**
|
||
- **Native** — Supported natively by the JavaScript engine.
|
||
- **➕** — Support added by this module.
|
||
- **Native (sometimes)** — Available in some builds (e.g., certain Small-ICU Node.js builds).

|
||
|
||
When your project needs to handle encodings like `latin1` / `iso-8859-1` or `windows-1252` in these environments,
|
||
native `TextDecoder` / `TextEncoder` may throw an error or return incorrect results.
|
||
|
||

## `textDecode(bytes, encoding): string`
|
||
|
||
Decodes binary data into a JavaScript string using the specified encoding.
|
||
|
||
**Parameters**
|
||
- `bytes` (`Uint8Array`) — The binary data to decode.
|
||
- `encoding` (`SupportedEncoding`, optional) — Encoding type. Defaults to `"utf-8"`.
|
||
|
||
**Returns**
|
||
- `string` — The decoded text.
|
||
|
||
**Example**
|
||
```js
|
||
import { textDecode } from "@borewit/text-encode";
|
||
|
||
const bytes = new Uint8Array([0x48, 0x65, 0x6c, 0x6c, 0x6f]);
|
||
const text = textDecode(bytes, "ascii");
|
||
console.log(text); // "Hello"
|
||
```
|
||
Encodes a JavaScript string into binary form using the specified encoding.
|
||
|
||
## `textEncode(input, encoding): Uint8Array`
|
||
|
||
**Parameters**
|
||
|
||
- `input` (`string`) — The string to encode.
|
||
- `encoding` (`SupportedEncoding`, optional) — Encoding type. Defaults to `"utf-8"`.
|
||
|
||
**Returns**
|
||
|
||
`Uint8Array` — The encoded binary data.
|
||
|
||
Example:
|
||
```js
|
||
import { textEncode } from "@borewit/text-encode";
|
||
|
||
const bytes = textEncode("Hello", "utf-16le");
|
||
console.log(bytes); // Uint8Array([...])
|
||
```
