# blob-store
Store blobs in a content-addressed way. This uses [@nichoth/multihash](https://github.com/nichoth/multihash) to create a unique hash for any file.
So far have only implemented a backend via [cloudinary](https://www.npmjs.com/package/cloudinary), but it would be good to implement other backends as well.
## install
```
npm i -S @nichoth/blob-store
```
## example
```js
require('dotenv').config()
const BlobStore = require('@nichoth/blob-store/cloudinary')
const cloudinaryUrl = require('@nichoth/blob-store/cloudinary/url')
import { scale } from "@cloudinary/url-gen/actions/resize";
const test = require('tape')
test('create a blob store', t => {
// this wraps the package 'cloudinary'
// takes the same config object
const blobStore = BlobStore({
cloud_name: process.env.CLOUDINARY_CLOUD_NAME,
api_key: process.env.CLOUDINARY_API_KEY,
api_secret: process.env.CLOUDINARY_API_SECRET
})
t.ok(blobStore, 'should create a blobStore')
t.end()
})
var _hash
test('blobstore.write', t => {
blobStore.write(file)
// get a hash here for a given file
.then(({ hash, response }) => {
_hash = hash
t.ok(hash.includes('.sha256'),
'should return hash, and create a sha256 hash as default')
t.ok(response, 'should return http response')
t.equal(response.public_id, hash, 'should use the hash as filename')
t.end()
})
.catch(err => {
t.fail(err)
t.end()
})
})
test('get a URL', t => {
// this wraps the package '@cloudinary/url-gen'
// takes the same config object
const cld = cloudinaryUrl({
cloud: { cloudName: process.env.CLOUDINARY_CLOUD_NAME },
url: {
secure: true // force https, set to false to force http
}
})
const url = (cld
.image(_hash)
.resize( scale().width(100) )
.toURL())
console.log(url)
// => https://res.cloudinary.com/nichoth/image/upload/GmuzSvBeEBT5tvt1vhtRkhl1a7V8MkTqCxT4Z4jFz_s.sha256?_a=ATAMhUk0
t.ok(url.includes('https'), 'should return an https URL')
t.ok(url.includes(_hash), 'url should include the right filename')
t.end()
})
```
