Quick Note to Node.js Users
|
||
------------------------
|
||
|
||
You SHOULD NOT use this module. You already have [`Buffer`](https://nodejs.org/api/buffer.html) and [`thirty-two`](https://github.com/chrisumbel/thirty-two):
|
||
|
||
```javascript
|
||
var buf = new Buffer('I ½ ♥ 💩', 'utf8');
|
||
buf.toString('hex');
|
||
buf.toString('base64');
|
||
buf.toString('ascii');
|
||
buf.toString('utf8');
|
||
buf.toString('binary'); // deprecated, do not use
|
||
```
|
||
|
||
API
|
||
===
|
||
|
||
```javascript
|
||
// TypedArray <--> UTF8
|
||
var uint8Array = Unibabel.strToUtf8Arr(str);
|
||
var str = Unibabel.utf8ArrToStr(uint8Array);
|
||
|
||
// TypedArray <--> Base64
|
||
var base64 = Unibabel.arrToBase64(uint8Array)
|
||
var uint8Array = Unibabel.base64ToArr(base64)
|
||
```
|
||
|
||
**Normal APIs**
|
||
|
||
`index.js`
|
||
|
||
* utf8ToBuffer(utf8str) => array
|
||
* bufferToUtf8(array) => string
|
||
* utf8ToBase64(utf8str) => base64
|
||
* base64ToUtf8(base64) => string
|
||
* bufferToBase64(array) => base64
|
||
* base64ToBuffer(base64) => array
|
||
|
||
**Hex APIs**
|
||
|
||
`unibabel.hex.js`
|
||
|
||
* hexToBuffer(hexstr) => array
|
||
* bufferToHex(array) => hexstr
|
||
|
||
**Base32 APIs**
|
||
|
||
`unibabel.base32.js`
|
||
|
||
* base32ToBuffer(b32str) => array
|
||
* bufferToBase32(array) => b32str
|
||
|
||
**Helper APIs**
|
||
|
||
* utf8ToBinaryString(utf8str) => binstr
|
||
* binaryStringToUtf8(binstr) => utf8str
|
||
* bufferToBinaryString(buffer) => binstr
|
||
* binaryStringToBuffer(binstr) => array

Examples

ChangeLog
|
||
====
|
||
|
||
v2.1.0
|
||
------
|
||
|
||
Added `unibabel.base32.js`
|
||
|
||
v2.0.0
|
||
------
|
||
|
||
The new implementation is binary compatible with node.js, TextEncoder,
|
||
and other more-common UTF-8 encodings.
|
||
|
||
It is also based on DOM APIs which result in much less code and are still
|
||
backwards compatible all the way back to IE6 (not on purpose, just that
|
||
it happens to work).
|
||
|
||
See <https://coolaj86.com/articles/base64-unicode-utf-8-javascript-and-you/>
|
||
|
||
v1.0.0
|
||
------
|
||
|
||
This version was based on the work by good folks at the MDN, however,
|
||
the UTF-8 conversion was not byte-compatible with other UTF-8 conversions
|
||
(such as node.js and TextEncoder), so don't use it.
