# BSER Binary Serialization
BSER is a binary serialization scheme that can be used as an alternative to JSON.
BSER uses a framed encoding that makes it simpler to use to stream a sequence of
encoded values.
It is intended to be used for local-IPC only and strings are represented as binary
with no specific encoding; this matches the convention employed by most operating
system filename storage.
For more details about the serialization scheme see
[Watchman's docs](https://facebook.github.io/watchman/docs/bser.html).
## API
```js
var bser = require('bser');
```
### bser.loadFromBuffer
The is the synchronous decoder; given an input string or buffer,
decodes a single value and returns it. Throws an error if the
input is invalid.
```js
var obj = bser.loadFromBuffer(buf);
```
### bser.dumpToBuffer
Synchronously encodes a value as BSER.
```js
var encoded = bser.dumpToBuffer(['hello']);
console.log(bser.loadFromBuffer(encoded)); // ['hello']
```
### BunserBuf
The asynchronous decoder API is implemented in the BunserBuf object.
You may incrementally append data to this object and it will emit the
decoded values via its `value` event.
```js
var bunser = new bser.BunserBuf();
bunser.on('value', function(obj) {
console.log(obj);
});
```
Then in your socket `data` event:
```js
bunser.append(buf);
```
## Example
Read BSER from socket:
```js
var bunser = new bser.BunserBuf();
bunser.on('value', function(obj) {
console.log('data from socket', obj);
});
var socket = net.connect('/socket');
socket.on('data', function(buf) {
bunser.append(buf);
});
```
Write BSER to socket:
```js
socket.write(bser.dumpToBuffer(obj));
```
