[![Build Status](https://travis-ci.org/finnp/postgres-blob-store.svg?branch=master)](https://travis-ci.org/finnp/postgres-blob-store)

[![BlobStore compatible](https://raw.githubusercontent.com/maxogden/abstract-blob-store/master/badge.png)](https://github.com/maxogden/abstract-blob-store)

This module is a PostgreSQL implementation of [abstract-blob-store](https://github.com/maxogden/abstract-blob-store)
and passes its tests.

Right now it doesn't use `bytea`, but is saving the binary files in `text` format as `base64`
Strings.

It is very experimental, since I have no clue about PostgresSQL. Your can install it 
with `npm install postgres-blob-store`.

## Usage

Right now the usage looks like this, however if possible I would like to get
rid of the callback structure in the beginning.

```js
var blob = require('postgres-blob-store')
var fs = require('fs')

var url = 'postgresql://localhost:5432/blob'

var store = blob({url: url})
var file = fs.createReadStream('./index.js')

var save = store.createWriteStream(function (err, metadata) {
  console.log('saved ' + metadata.key)
  var readStream = store.createReadStream(metadata)
  readStream.pipe(fs.createWriteStream('./index2.js'))
})

file.pipe(save)
```
